2-flute Carbide Drill Bits (DC208) - 1/8 in. (0.125 in. shank)

Think & Tinker 2-flute carbide drill bits were designed and optimized for the fabrication of printed circuit boards on a wide variety of substrates. Decades of design improvements has expanded their application range to hard and soft woods, metals, glass and carbon-fiber composites and reconsititued minerals.

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 ) with a bonded stainless steel shank
  • Geometry - 2 flute, 1/8in. (3.18 mm) shank, drill point
  • Length - 1.5in. ±0.010 in.
