The 3M 7100239947 is a purpose-built 665BL diamond wheel optimized for cutter grinding and tooling applications. This 1E1 resin bond diamond wheel delivers a controlled cut ideal for producing precise cutter profiles and repeatable kerf widths. Manufactured to tight tolerances, the wheel minimizes runout and vibration for consistent surface integrity on tooling. 3M 1E1 D320 V60 diamond grading gives a balance of cutting speed and finish quality for common cutter materials. Resin bond construction helps manage heat and reduce glazing during prolonged cutter grinding cycles. The 665BL geometry supports thin-kerf cutting while preserving stability and wheel life in batch or single-part production. Operators will find predictable dressing intervals and steady performance when dressed to the required profile. This 3M 665BL diamond wheel for cutter grinding integrates easily into standard cutter grinder spindles and fixtures. Durable construction and balanced manufacturing reduce the frequency of wheel changes and downtime. The wheel is suited for trimming, shaping, and light stock removal on carbide and high-speed steel cutters. Repeatable kerf control aids downstream processes by improving blank uniformity and reducing rework. Consistent lot-to-lot quality simplifies procurement and inventory planning for production shops. Compatibility with coolant practices and standard dressing procedures ensures safe, reliable operation. Choose the 3M 7100239947 when in need of an industrial-grade wheel that prioritizes accuracy and service life. This 3M 665BL 1E1 diamond grinding wheel is an effective solution for toolrooms and production lines demanding precise cutter finishing.
1E1 Cut Geometry For Thin Kerf Control
