3M 7010491856 | 4.000" Diameter x 0.750" Thickness Cutter Grinding Wheel

The 3M CBN Wheel 144BI wheels are used for grinding primary and secondary relief angles on cutting tools made of tool steel and high speed steel. This general purpose wheel offers high cut rates and good form retention during grinding operations.

The 3M CBN Wheel 144BI was designed for high performance primary and secondary relief grinding. This process is used in the production and sharpening of cutting tools. Cutting edges are typically "relieved" to enhance chip clearance. Primary relief involves removing material directly behind the cutting edge. For secondary relief, a slight bevel is ground next to the primary relief.

3M provides a broad portfolio of superabrasive wheels used for your round tool relief and clearance angle applications. From short runs and re-sharpening to "lights-out" and long production runs.

Features:

• Best used for grinding high speed steel, tool steels, and ferrous metals
• The resin bond system provides enhanced cut rate with good form retention
• Cubic boron nitride abrasive mineral provides fast cut rates at high temperatures
