CBN plated over entire edge and also 18mm in from the face (that side hidden in photo). Fits to your grinder - maximum speed 3000 rpm. Centre hole is 32mm but we will include suitable precision machined bushes to suit your grinder shaft. Please specify bore required.

  • Perfect for sharpening all steel and HSS tools especially woodturning tools
  • Superfine grit for a superfine edge
  • Outlasts conventional wheels many times over
  • Grinds cool and very fast
  • Does not wear down to a smaller size
  • Never needs dressing
  • You can grind skews on the face, leaving a flat bevel as shown on second photo below
Cubic Boron Nitride is far better than diamond for grinding steel and will outlast a diamond plated wheel many times over. It is also tougher so will perform well at all speeds up to 3000 rpm. No coolant is required. Hardly any sparks are generated, proving that the wheel is cutting much cooler and more efficiently than any conventional grinding wheel. Carbon steel carpenters tools and plane blades can be sharpened as well as HSS (with care!)
Shipping cost to U.S.A. is £26. (contact us direct by email for exact quotation - do not order online)
The hole in the centre is 32mm. We can supply bushes for most sizes of grinder shaft. Grit is equivalent to 320/400.

For lathe mounting we can machine a dovetailed chuck recess to enable the wheel to fit chuck jaws, at extra cost, or alternatively we can supply a threaded adapter which enables the wheel to screw onto your lathe thread.
