These wheels will change the way you sharpen forever – Think razor sharp edges.

CBN or Cubic Boron Nitride grinding wheels are electroplated and nickel coated. Why? Electroplating offers many advantages over other applications. It creates a more aggressive bond over other applications and will hold a form longer. It also performs a higher stock removal rate and will last for years. They are designed for sharpening high speed steels only and should not be used for other applications. These wheels have a 1.5" face so they are easy to use and work well with the Wolverine Sharpening System. The 180-grit wheel puts almost a mirror finish on your edges and makes them "scary sharp."

The 80-grit wheel whips your tools into the profile you want and you can even finish grind your tools with it as well as raise a burr for your scrapers. A unique feature of this wheel is the 1/4" radius on the left and right side of the wheel. The radius makes it easy to grind small 1/4" hollowing bits and round scrapers. This eliminates the problem of having to rotate a tool by the handle (in the case of scrapers) and end up over-grinding the tip. This is a very handy feature, and you can hold the small bits and not burn your fingers. You won't find a better wheel at these incredible prices. Money back guarantee.

Please be advised that due to the width of these wheels in most cases the guards on your grinder may have to be removed. As long as the wheels are properly used as intended this should not cause a problem as they are machined from one solid piece of 6061 aluminum. KJR Distributing, LLC, dba WoodTurners Wonders assumes no risk of consumer usage of these wheels and shall not be liable for any damages whether direct, indirect, incidental, special or consequential arising out of or in connection with the use of these products.


Q: Which Grit CBN wheels should I buy?

A:  That depends on your style.  If you reshape tools often or make some of your own tools on occasion, get the 80-grit wheel as your low grit wheel.  If you don’t do that type of grinding much, then get the 180 grit.  For sharpening and touching up your tools we suggest the 350 or 600. The 350 grit wheel is better for softer tool steel like M2 while the 600 works well with M42 and Powdered Metal.  Use of our Wonder Slick Stick is suggested with both of those grits to help keep the wheel clean and from loading up with particles of metal.  They will leave a scary sharp edge on your tool and remove very little metal, leaving you with a tool that will last a lot longer. We suggest you read the article by Tom Wirsing in our Blog section for additional guidance.

Q: I have heard that you can only sharpen certain types of steel with CBN wheels. What should I avoid?

A: Stay away from soft steels; aluminum, brass, and high carbon tools to name a few.  A good rule of thumb is if the item being ground throws off a lot of sparks then don’t make a steady habit of grinding it.  Occasionally is ok as long as long as you go back to sharpening high quality steel so it will help clean out the pores in the wheel.

Q: You have so many styles of wheels.  Which one should I get?

A:  All our wheels are constructed the same way (except the Tormek style wheel with the Nylon Center) and carry our famous lifetime warranty.  Wheels with Radius edges are great for sharpening smaller hollowing bits and round nose scrapers.  The main reason for this is the tool can be kept straight on the platform and just moved around the edge of the wheel.  Wheels with grit on the side like the 4 in 1 (which also has a radius) and the Mega Square are great for doing non hollow grinds on skews.  Our new Kodiak sharpening platform has a fixture to hold the skew in the right position when using the side of a wheel.  Our Spartan wheels are 1 inch wide with ¼ inch on the side.  Our Radius edge wheels are 1.5 inches side with a ¼ inch radius on the edge and no grit on the side.  Our 4-1 wheels are 1.25 inches wide with ¼ inch radius and 1 inch on the side.  Our Mega Square wheel is 1.5 inches wide, no radius and 1 inch down the side.  Our tormek-style wheels come in similar styles, to be used on Tormek grinders; The Spartan 10 inch which is 2 inches wide with a band of steel around Nylon and no grit down the side.  These will fit all 10 inch Tormeks.  The Tornado Tormek is 10 x 2 inch with 1 inch down the side and is constructed out of 6061 Aluminum like out other wheels.  The Tornado Jr is for the T-4 model Tormeks and are 1.5 x 8 inch in size. Shaft arbor sizes are 5/8  or ¾ for the 8 inch wheels,  ½ for the 6 inch wheels and 12 MM for the Tormek wheels.  Please check out our video section to see an in-depth explanation of our wheels.

Q: Will the wheels fit/run on my grinder?

A:  Most likely the answer is yes.  Most 8-inch grinders out there have a 5/8 shaft and some (Baldor 8 inch) have ¾ inch shafts and we carry both sizes.  Our 6-inch wheels have ½ inch shafts as most 6 inch grinders do.  We do carry a step-down bushing from 5/8 to ½ inch for those oddball grinders.  Our Radius Edge, Mega Square and 4-1 design wheels have hubs that are 1.25 inches wide so they will fit on most 2-inch-long shafts and have room for the self-alignment washer kits.  Our Spartan wheel hubs are 1 inch wide and have a 5/8 arbor and 1 inch long hub.  It may be necessary to purchase additional flat washers to make sure the threads on the shaft can reach the Spartan wheel or if it is desired to keep the guard on the grinder.  It may be also necessary to have a flat washer between the wheel and the motor to keep the guard on so there is enough clearance. 

Q:  Should I get by the ½ HP Rikon or should I buy the 1 HP?

A:  That depends:  If you watch the video on start up times its pretty evident the 1 HP is ready to go in 2 seconds.  The ½ HP takes 7-10 seconds depending on the wheels being used.  That really is the major deference.  Both machines will get the job done mainly because when used with CBN wheels, little pressure is needed because the wheels cut so wheel.  If you do a lot of reshaping of tools (think heavy grinding) then it would be wise to get the one horse as its extra power will mean a longer life in the long run. 

Q:  Which Lamp should I buy?

A:  The lamp you choose depends on a few things.  Where do I want to put it, what will it be used for, and how will I want to mount it?  If you plan on mounting your lamp to your lathe headstock, we feel the better lamps for those are the Aurora or Quasar model. Main reason for that is the flex pipe on that lamp goes into the side of the lamp housing at a 90-degree angle as opposed to the Super Nova and Beacon whose flex pipe goes into the back of the lamp head. This 90-degree orientation lends itself to making a more graceful arc into the face of the bowl for visibility of the inside turning surface. All our lamps, except the Galaxy, have 30 inch long necks that will stay in place where you

Grinding Excellence

Having read about the benefits of CBN wheels, I decided that I wanted to try one out for myself. I found Woodturners Wonders and decided that the Mega Square wheel was exactly what I needed. Not only was it 5/8th inch bore but offered a full 1" of abrasive material on each side for flat grinding which is my preference and is in excess of anything Ken answered many questions whilst I was making up my mind. It is good to be dealing with a woodturner rather than a tool outlet company. The wheel slipped beautifully onto my grinder's arbor and within 10 minutes, was running completely true thanks to the comprehensive fitting instructions. Early days yet for me but I have already sharpened several skews and gouges and a couple of parting off tools. These wheels are superbly engineered and grind so well that I wish I had bought one years ago.

Best Of The Best

Probably the best single item I've ever purchased for my lathe turning. You can buy all the best quality gouges, chiesels or any lathe tools, but without a quality turning wheel, you'll be spending more time Sharping and eating stone dust. I love the ease of mounting this wheel and the initial sharpening is unmatched, particularly with it's 1 1/4 in. width and large sidewalls. This is an unbelievably dependable, durable and reliable wheel. My only regret, Why didn't I buy one earlier. This is my 2nd or 3rd purchase from WoodTurners Wonders and I can only compliment them on the efficiency and professional courtesy given when ordering. I'll most definitely be ordering items in the future, as well as giving many "coodoos" to friends and fellow turners.

Surprisingly Nice Wheel

I ordered a complete system along with an extra "cheap" wheel in 1000 grit for knife sharpening. The Spartan wheel was delivered first and Wow! It's freakin nice. Mirror finish, excellent machining, and all around impressive wheel. I had to show it of to the few buddies I've got that would know what a cbn wheel is. Can't wait for the rest of the stuff to show up. If the Spartan is this nice, I can't wait to see the squares!

I'm Impressed!

It's not often that a product exceeds the claims of the salesman. This one did it. The wheels run amazingly true and the cut is smoother, more aggressive and cooler than any wheel I have ever used. The only complaint I have is that they won't tolerate carbon steel and as most tools these days are HSS that's not that big a deal. No need to hone or strop after using the 350 wheel. Just one light pass and the edge is razor sharp again. A great product at a reasonable price.
