Radius Edge CBN Wheel 8-inch, 5/8" arbor
What are CBN or Cubic Boron Nitride grinding wheels? They are electroplated, nickel coated, and balanced.
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 Closer Look at CBN: 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.
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.
