2-flute Carbide Fish-tail (Square) End-mills (MM204) - 1/4 in. (0.250 in.) shank
Think & Tinker 2-flute end-mills feature an off-center 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 ±0.0015 in. (0.038mm), virtually eliminating the need for resetting Z-axis zero between tool changes (with bits of same overall length)
- made from premium grade submicrograin tungsten carbide (HRa 92, HRc 80)
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.
