3M 7010493379 | 1.250" Center Hole Diameter x 4.000" Overall Diameter x 0.250" Thickness x 674BN Wheel Type 1F1 Resin Bond Diamond Wheel

Description

The 3M 7010493379 674BN resin bond diamond wheel is built for precision grinding of cutting tools and carbide components. This wheel measures 4.000" overall diameter, 0.250" thickness, with a 1.250" center hole for standard mounting and low runout. Diamond abrasives provide high cutting ability and long life when working on cemented carbide and other superhard materials. The 3M 1F1 diamond grinding wheel configuration produces a narrow, controlled contact face that supports accurate form and profile control. Resin bond chemistry is tuned to balance abrasive exposure and bond retention for consistent stock removal and finish. A thin 0.250" section allows fine profile definition and tight-tolerance material removal on tool edges. Durable construction and balanced assembly reduce vibration and improve surface finish consistency in high-precision work. Correct coolant application helps control thermal transfer and preserves both wheel life and part metallurgy. Predictable wear behavior lowers dressing frequency and improves uptime in production environments. Available in multiple grit options, the 674BN can be matched to the required cut rate and finished surface quality. This industrial diamond abrasive wheel is suitable for OD, face, and form grinding on a variety of cutting-tool geometries. Operators benefit from repeatable performance, reduced rework, and improved throughput when using this wheel. The 3M 7010493379 is compatible with conventional toolroom spindles and CNC grinding centers when properly mounted. For demanding carbide applications, this superabrasive diamond wheel provides the balance of life and form retention needed. Consult your distributor for exact sizes, grit choices, and mounting recommendations to optimize performance.
