3-flute Mother-of-Pearl / Shell / Soft Stone Cutters (MS3I8) - (0.125 in. shank)

After years of experimenting with different flute geometries, tip designs and cutting parameters, we finally have a cutter that is optimized for high-speed cutting of natural mother-of-pearl and abalone. Superior bit life and fracture-free edges with no chipping or flaking are the result of a cutter geometry that is precisely tuned to the machining properties of natural shell products and close-grained hardwoods. The tools are designed specifically for use in CNC based cutters where relatively high, uniform feed rates can be maintained.

Manufactured in the USA, every tool is:

  • 100% measured / optically inspected to insure that EVERY tool meets, or exceeds, our published specifications
  • available with depth rings precisely positioned to ±0.004 in. (0.10mm), virtually eliminating the need for resetting Z-axis zero in many applications)
  • made from premium grade submicrograin tungsten carbide (HRa: 93, TRS: 4.0GPa )

When cutting cutting rosewood, ebony or African blackwood (Janka value greater than 2,700 lbf) or any wood with a high silica content, enhanced performance can be achieved with these relieved-neck 3-flute cutters because of their superior stiffness and resistance to breakage.

MADE IN USA
