3M 7010492024 | 4.000" Diameter x 0.500" Thickness Cutter Grinding Wheel

3M CBN Wheel 144DI is used for grinding primary and secondary relief angles on cutting tools made of tool steel and high speed steel. This resin bonded wheel offers both free cutting action and good form retention, as well as increased thermal stability during higher temperature grinding operations.

• 3M CBN Wheel 144DI 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.
The Right Wheel for Every Job
• 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:

• Designed to be free cutting while retaining good form retention
• Used for flute grinding on high speed steel, tool steels, and ferrous metals
• Cubic boron nitride abrasive mineral provides fast cut rates at high temperatures
• Resin bond improves thermal stability during high temperature grinding operations
