CBN 8" Wheels - 4 in One

CBN Wheels - 4 in One   What is CBN?—Cubic boron nitride (CBN) is a synthetic chemical compound made up of boron and nitrogen atoms in a one-to-one ratio. It exists as a cubic crystal lattice, with its atoms arranged in a symmetrical, cube-shaped structure like the crystalline structure of diamond. Its material properties include extreme hardness, stability under heat, and superior chemical resistance. Cubic boron nitride is the second-hardest known material after diamond, making it useful in a wide variety of industrial applications, where it is often used as an abrasive or cutting tool. The heat resistance of CBN is quite high. Diamond begins to decompose to carbon dioxide in air at around 1,472°F (about 800°C), whereas cubic boron nitride is stable in air up to about 2,552°F (about 1,400°C). In industrial grinding applications and other processes where intense heat is generated, CBN is preferred over diamond.   4 in One :                           8" Wheel Width 1.25"                          1/4 inch radius   CBN material on both sides of 1 inch                           80, 180 or 220 Grit                                         If purchased as a pair: $319.99 This wheel has four use-able functions:  1) It has the face of the wheel for normal sharpening and is 1.25 inches wide. 2) It has the 1/4 inch radius on each side as our present best seller for sharpening hollowing tool bits and scrapers.  3) It has a total side face of CBN material on both sides of 1 inch for non-hollow grinding of skews and scrapers! 4) There is a 9 mm 90 degree gap (about 1/3 of an inch) space shoulder on the inside edge of the grinding wheel for making relief cuts or tapers on hook type scrapers or box scrapers. This wheel is 8 inches in Diameter and has a 5/8 Arbor hole.   Disclaimer on CBN grinding wheels: Please be advised that due to the width of these wheels in most cases the guards of your grinder may have to be removed. As long as the wheels are properly used as intended this should not cause any problems as they are machined from one solid piece of 6061 aluminum.

Enter CBN or Cubic Boron Nitride grinding wheels. They are electroplated, nickel coated, and balanced. Why? Electroplated 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. These are designed for sharpening high speed steels only and should not be used for other applications. A unique feature of both the 80 and 180 grit wheel is the 1/4 inch radius on the left and right side of the wheel. The radius makes it easy to grind small1/4 inch hollowing bits and round scrapers. This eliminates problems 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.  The wheels have a 1.25 inch face so they are easy to use and work excellent 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.  You won't find a better wheel at these incredible prices.
