PreciseBIT 2-flute, Micro-engraving, PCB Traces Isolation Bits (EM2E8) - (0.125" shank)

Engraving / Metal Cutting

PreciseBits 2-flute spiral V-tip mechanical etching and PCB trace isolation tools offer an optimum combination of high-resolution cutting and tip strength. The plunge style tip geometry insures burr-free material removal at all plunge depths and cutting widths.

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. (0.038mm), 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.
