Hand Tools, 8" CBN Grinding Wheel, 180 Grit, 1.5" Wide, 5/8" Bore, for Sharpening High Speed Steel Tools

Series II wheels are made from an aluminum core, which is lighter in weight than steel and will run smoother on all grinders
Ideal for sharpening woodturning tools (High Speed Steel only)
Designed for use with bench type grinders; 1800 RPM (Preferred) or 3600 RPM
Wheel diameter does not change over time; CBN material is on the face and sides (1/4") of the wheel
Balanced in the manufacturing process and never need "Truing" or "Dressing"

Hand Tools Cubic Boron Nitride (CBN) Grinding Wheel 8" Diameter - 1.5" Wide, 5/8" Arbor - 180 GritWe would like to introduce you to the state of the art in bench grinding, Hurricane Series II Aluminum core CBN plated grinding wheels. Cubic Boron Nitride (CBN) is a man-made crystalline material which is one of the hardest materials in the world. It is just slightly below Diamond on the hardness scale. CBN grinding wheels have been used in manufacturing processes for many years and are now available for common bench grinders. CBN crystals are electroplated on to a precision aluminum grinding wheel substrate resulting in the finest grinding wheels available today. CBN wheels outperform common stone wheels in many ways.Features:Series II wheels are made from an aluminum core, which is lighter in weight than steel and will run smoother on all grindersIdeal for sharpening woodturning tools (High Speed Steel only)Designed for use with bench type grinders; 1800 RPM (Preferred) or 3600 RPMWheel diameter does not change over time; CBN material is on the face and sides (1/4") of the wheelBalanced in the manufacturing process and never need "Truing" or "Dressing"Available in coarse and fine gritThey can make an inexpensive grinder perform almost as well as an industrial grinderThe second picture shows comparison of 80 Grit and 180 Grit Wheels
