I agreed to review its performance but hesitated to write anything immediately because I had some initial reservations that would only be answered after a few months of use.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eMy first impressions were very favourable. The wheel is an 8″ aluminium disc with a 6mm layer of diamond encrusted resin on the grinding surface. I hooked it up to the bench grinder and it ran nice and true and was well balanced which meant there was no need to contemplate how to dress it at this stage.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eI started by grinding a skew chisel. Wow. The finish was very impressive and very sharp. I did another skew and then a scraper with the same results. At this point my feelings were similar to those when I have discovered anything that will make a significant difference to my woodturning;. I was excited with the prospects. Next it was onto the bowl gouge. I sharpen freehand so I found this process difficult because there were no sparks to guide me. For me this was one of the down sides to this wheel because I find sharpening tools freehand quick and easy; no need for mucking around with jigs. However it became obvious to me that a sharpening jig will be essential for this wheel to be a successful addition to my sharpening regimen.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rich-text-content-block rich-text-content-block--with-float\"\u003e\n\u003cdiv class=\"rich-text-content-block__content\"\u003e\n\u003cp\u003eBut one of the most impressive things is that I found it difficult to burn the steel. Yes, hard to believe but it is true. I had to press very hard onto the wheel with the tool to get it to burn.\u003c\/p\u003e\n\u003cp\u003eOne of my initial concerns centered around the issue of dressing the wheel once it started to dish in the middle and get dirty, as is the case with most wheels. Well, after 4 months of use I am surprised to see no evidence of dishing and the wheel grinds equally as well without any dressing. In fact I don’t know how I would dress the wheel if I had to and all I have done is wiped the surface with a damp rag to clean it. There has also been an undetectable amount of wear of the grinding surface.\u003c\/p\u003e\n\u003cp\u003eThe cost of the wheel is US$150. Worth it? To answer this question I would have to compare it to its competitors. Given the finish achieved the competitors are the water grinding wheels more so than the al oxide wheels. Water wheels are considerably more expensive than the Wood River wheel so that would suggest they are worth the price if that is the sort of finish you need on your tools. To compare the price of the Wood River wheel to an al oxide wheel is a little unfair but if this is the bottom line then it is approximately 4 times the price. However this doesn’t take into consideration the fact the aluminum oxide wheels wear a lot quicker. Four times quicker? I’m not sure; only time will tell.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rich-text-content-block rich-text-content-block--with-float\"\u003e\n\u003cdiv class=\"rich-text-content-block__content\"\u003e\n\u003cp\u003eSo far this review has been from a woodturners perspective but to ignore a number of other applications would be doing it an injustice. I think this wheel would be very advantageous to those sharpening chisels, plane blades, knives and carving tools especially if used for the initial grind. I have sharpened my kitchen knives on it with very good results. I also sharpened a plane bade and used it with good results without any further fine sharpening or honing.\u003c\/p\u003e\n\u003cp\u003eMy only criticism of the product is its distinct lack of instructions and information. The wheel arrived in a box with the product description on the outside and nothing else. While the same can be said about al.oxide wheels, being a new concept in grinding wheel technology and given its price some information would help overcome some apprehensions potential customers may have. I have had many people ask me how to dress the wheel or clean it and there is simply no information to answer these fundamental questions.\u003c\/p\u003e\n\u003cp\u003eOverall, I think the Wood River diamond wheel is well worth considering and certainly is a serious contender for those not happy with the al. oxide wheels and perhaps considering the water wheel option. I would certainly recommend them for woodturning tools but only with some sort of guiding jig.

WoodRiver CBN Grinding Wheel

Product Description

When I find a good product I tell folks about it; when I find an excellent product I sell it.  This grinding wheel is one of those rare above excellent products I run across every now and then. I am so impressed by this grinding wheel that I replaced all the grinding wheels in my shop with this one.  It is such an  improvement on my old ceramic stone grinding wheels thats its almost unbelievable!

Here is what I love about this grinding wheel:

  • 120-Grit, Cubic Boron Nitride (CBN) coated wheel, cuts significantly faster as compared to Aluminum Oxide or other ceramic wheels.

  • 8" diameter x 1" wide, with 5/8" arbor.

  • Wheel balance is not an issue because the wheel is machined from solid steel plate.

  • Coated with CBN from edge to edge, as well as for a short distance down the face.

  • Solid steel wheel acts like a heat sink making tool overheating or burning much less likely.

  • CBN coating never loads up or requires dressing.

  • Economical: the CBN coating lasts for years under normal use

Cubic boron nitride, commonly known as CBN, is a man-made synthetic abrasive. CBN is made from cubic boron nitride grains bonded together by ceramic material.  CBN is the second hardest material after synthetic diamonds.

The process of making CBN abrasive is similar to that of synthetic diamonds: scientists treat hexagonal boron nitride at high temperature and pressure to create cubic boron nitride and treat graphite in the same way to create diamond.  

CBN is well suited for ferrous materials in grinding operations, as it will not carbonize when interacting with iron (Fe), as diamond abrasives may. Typically, CBN is used for grinding steel, cast iron, die steel, tool steel, super alloys, and in some cases ceramic materials.

CBN has several attractive characteristics that make it superior to diamond in grinding operations:

  • Withstands heat, especially during high-speed applications

  • Does not cause grit that can dull bits

  • Stays sharp and cool because it does not react with steel

  • Diamonds can also react with transition metals, limiting their usefulness for grinding certain materials. Cubic boron nitride is stable and does not tend to react unfavorably with standard transition metals.

CBN grinding wheels are made by electroplating CBN particles on steel, using electroplated nickel to hold the grit in place. A single layer of CBN grit applied to the surface of a metal disc can grind even the hardest surfaces and last for years.

Brendan Stemp of Australian Wood Review, October 2016

In February this year I acquired a WoodRiver 120 grit diamond grinding wheel; an 8” wheel designed to be mounted on a standard bench grinder. I agreed to review its performance but hesitated to write anything immediately because I had some initial reservations that would only be answered after a few months of use.

My first impressions were very favourable. The wheel is an 8″ aluminium disc with a 6mm layer of diamond encrusted resin on the grinding surface. I hooked it up to the bench grinder and it ran nice and true and was well balanced which meant there was no need to contemplate how to dress it at this stage.

I started by grinding a skew chisel. Wow. The finish was very impressive and very sharp. I did another skew and then a scraper with the same results. At this point my feelings were similar to those when I have discovered anything that will make a significant difference to my woodturning;. I was excited with the prospects. Next it was onto the bowl gouge. I sharpen freehand so I found this process difficult because there were no sparks to guide me. For me this was one of the down sides to this wheel because I find sharpening tools freehand quick and easy; no need for mucking around with jigs. However it became obvious to me that a sharpening jig will be essential for this wheel to be a successful addition to my sharpening regimen.

But one of the most impressive things is that I found it difficult to burn the steel. Yes, hard to believe but it is true. I had to press very hard onto the wheel with the tool to get it to burn.

One of my initial concerns centered around the issue of dressing the wheel once it started to dish in the middle and get dirty, as is the case with most wheels. Well, after 4 months of use I am surprised to see no evidence of dishing and the wheel grinds equally as well without any dressing. In fact I don’t know how I would dress the wheel if I had to and all I have done is wiped the surface with a damp rag to clean it. There has also been an undetectable amount of wear of the grinding surface.

The cost of the wheel is US$150. Worth it? To answer this question I would have to compare it to its competitors. Given the finish achieved the competitors are the water grinding wheels more so than the al oxide wheels. Water wheels are considerably more expensive than the Wood River wheel so that would suggest they are worth the price if that is the sort of finish you need on your tools. To compare the price of the Wood River wheel to an al oxide wheel is a little unfair but if this is the bottom line then it is approximately 4 times the price. However this doesn’t take into consideration the fact the aluminum oxide wheels wear a lot quicker. Four times quicker? I’m not sure; only time will tell.

So far this review has been from a woodturners perspective but to ignore a number of other applications would be doing it an injustice. I think this wheel would be very advantageous to those sharpening chisels, plane blades, knives and carving tools especially if used for the initial grind. I have sharpened my kitchen knives on it with very good results. I also sharpened a plane bade and used it with good results without any further fine sharpening or honing.

My only criticism of the product is its distinct lack of instructions and information. The wheel arrived in a box with the product description on the outside and nothing else. While the same can be said about al.oxide wheels, being a new concept in grinding wheel technology and given its price some information would help overcome some apprehensions potential customers may have. I have had many people ask me how to dress the wheel or clean it and there is simply no information to answer these fundamental questions.

Overall, I think the Wood River diamond wheel is well worth considering and certainly is a serious contender for those not happy with the al. oxide wheels and perhaps considering the water wheel option. I would certainly recommend them for woodturning tools but only with some sort of guiding jig. Still, I have hesitations based on its performance after a far longer period of time, perhaps a year or two.

    Amazing

    The slow speed grinder is an important tool for my woodworking. Working with hand planes, bench chisels, carving tools, and turning tools, I’m on the grinder almost daily. It is set up with Wolverine grinding jigs for speed and accuracy. Before replacing my wheels with the CBN wheels (120 and 180 grits), my biggest problem was overheating, or “bluing” the corners of plane irons, chisels, and gouges. To avoid this, I needed to work slowly, constantly cooling my tools in a jar of cold water. The other process that slowed me down was dressing the wheels. The CBN wheels are amazing. They are true and cool. The steel rims draw heat away from the surface and dissipate it without over-heating my tools. Hi he wheels never need dressing, and hold their perfectly flat shape. The 120 grit wheel works amazingly fast, enabling me to hollow-grind chisels and plane irons in a matter of seconds. The other day I wines up my adze, axe, and steel wedges to rough hue timber and the wheel worked fast and true. The 120 grit, when used with a very light touch, quickly puts a nearly polished edge on the bevels of my turning tools, bringing my lathe work to a new level; and it’s so quick and easy that I don’t hesitate to sharpen the tools at are slightest hint of dullness. This principle I learned through embracing Rob Cosman’s sharpening system tor my chisels and plane irons - using the Trend 300/1000 and Sharon 16000 grit stones for wiockly maintaining razor sharp edges. If sharpening is nearly risk-free, and very quick, it becomes a welcome pleasure rather than a burden. That’s what I have experienced with the CBN grinding wheels. They are Definitely worth the money! I have one suggestion for the manufacturer. Make a 180 or higher grit wheel with convex, rounded edges for the inside bevels of carving gouges. Those of us who have experienced the benefits Chris Pye’s inside bevel approach will buy them in a New York minute.
