3M™ Resin Bond CBN Wheels and Tools, 14A1, 7.874X.394X3.5433

The 3M 394x3 Wheel is made for precise grinding work where clean results are important. It is part of the 3M Resin Bond CBN line, type 14A1, and comes in a size of 7.874 x .394 x 3.5433 with a 1/8 thickness. This wheel is often used for sharpening tools, surface grinding, cylindrical grinding, and centerless grinding on High Speed Steel (HSS) parts.

The 3M 394x3 uses a strong resin bond paired with CBN abrasive. This design helps the wheel keep its shape longer, which means less dressing and more consistent performance over time. Operators can focus on steady grinding instead of frequent wheel adjustments.

This wheel works with both oil and emulsion coolants, which helps manage heat during grinding and keeps the surface of the part in good condition. Many users notice tighter tolerances and shorter cycle times, which makes the process more efficient and reliable.

Because the wheel removes material at a steady rate and lasts longer between changes, downtime is kept to a minimum. This also reduces waste and keeps work flowing without unnecessary interruptions.

For tool rooms, machine shops, and other environments where consistent grinding is required, this wheel is a practical choice. Following standard mounting and RPM guidelines can extend the wheel’s life and maintain consistent results over longer runs.

• Improved profile retention and reduced dressing efforts
• Free-cutting bond
• Improved surface quality and higher geometric accuracy
• Shorter cycle-times
• Higher productivity/high removal rates
