This CBN wheel is 200mm diameter and 32mm wide. The coating continues around a 6mm radius on each side. This is most useful for sharpening smaller or shaped tools, as it gives you more control over where metal is being removed. The wheel’s 180 grit coating produces sharp edges on HSS tools. Cubic Boron Nitride (CBN) is a ceramic abrasive second only to diamond in hardness for outstanding performance.
The wheels run ultra smoothly when fitted to a suitable bench grinder. CBN wheels are at their best when grinding HSS steels and hardened carbon steels. They are invaluable for maintaining the edges of woodturning tools and other hand tools. CBN is the best material for grinding hardened steels. Attempting to grind unhardened steel or soft metal such as aluminium or copper etc is detrimental to performance and results in a clogged wheel.
These wheels do not require coolant, as they generate hardly any heat. Very little pressure is required to sharpen a tool; generally, the weight of the tool alone is sufficient. The face of the wheel will never need dressing; it will always remain flat and run true.
These outstanding wheels have an almost indefinite life if treated with respect. Since they cut very efficiently, you only remove a minimum of steel to get a fine and evenly sharp cutting edge, meaning your tools last longer.
Please note, these wheels have a 31.75mm bore, adaptors may be required for fitting to some bench grinders.
Sides feature 6mm radius for small or shaped tools
