CNC router bits and carbide cutting tools with tutorials and technical guides

2-flute Carbide Ball-nose End-mills (MM208) - 1/8" (0.1250" shank)

Think & Tinker 2-flute miniature and micro end-mills feature a high axial rake plunging tip style enhanced with revisions to the cutting edges and flute profile. These changes result in bits with improved cutting properties in a wider range of materials. Our tools are routinely used to shape and engrave metals, plastics, all types of woods and a wide variety of composites.

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 )

This attention to detail and the use of top quality materials result in tools with dependable cutting characteristics and one of the longest tool lives in the market. Combined with comprehensive customer support, our cutters have become the tools of choice for sign makers, model makers, artists and instrument builders around the world.
