3M 7010493449 | 0.787" Center Hole Diameter x 6.000" Overall Diameter x 655DK Wheel Type 1A1 Resin Bond Diamond Wheel

Description

The 3M 7010493449 655DK diamond grinding wheel is made for precision profile grinding on carbide and high-speed steel tooling. Built with a 1A1 resin bond, this wheel balances aggressive cutting with controlled wear for predictable form retention. A 0.7874" center hole provides secure mounting and low runout on standard tool grinder arbors. The 6.000" overall diameter offers stability and the working face needed for complex profile operations. The diamond abrasive formulation ensures extended life and consistent surface quality across long production runs. As a 655DK product, the wheel It is optimized for tool grinders performing intricate relief and flute grinding tasks. The resin bond matrix supports effective diamond retention while permitting controlled grit exposure for finishing passes. Engineered to reduce dressing frequency, the wheel improves throughput on repetitive profile-shaping cycles. Balanced construction reduces vibration and produces repeatable geometries and improved edge concentricity. Suitable for both bench and production tool grinders, the wheel integrates with common grinding setups. Heat management and bond formulation maintain abrasive effectiveness during moderate to aggressive stock removal. This 6-inch resin-bond diamond wheel with a 0.787 center hole simplifies replacement and inventory standardization. Proper dressing and speed selection help preserve profile accuracy and prolong the service life of the 655DK wheel. Manufactured to 3M quality standards, the 3M 655DK diamond grinding wheel supports consistent tool-making and regrinding workflows. Choose 3M 7010493449 for stable form control, long life, and consistent tool geometry.
