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

Diamond-cut Down-cut Router Bits (RDDXX) - (fish-tail tip)

Think & Tinker solid carbide router 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 glass and carbon-fiber composites, reconstituted minerals, bisque, ceramic tile and masonry.

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 )
  • Geometry - diamond-cut down-cut flutes, 1/8in. shank, fish-tail point
  • Length - 1/8 in. shank - 1.5in. ±0.010 in.
  • Diameter - nominal +0.000 in., -0.002 in.
  • Max runout (TIR) - < 0.0005 in.
  • Max. depth of cut - EFL varies by diameter ±0.005 in.
  • Anticipated Life - anticipated life: 3,000 linear in. (FR4 epoxy glass)
  • Material - solid submicrograin carbide
  • Ring Set - 0.800 in. ±0.002 in. (optional)
  • Operating RPM - CNC certified operation 8k RPM to 60k RPM
Carbide diamond-cut down-cut router bits for PCB contouring, PCB depaneling, carbon fiber contouring and composite cutting
LPKF and T-Tech users must specify the make and model number of their CNC routers to insure that the rings are properly positioned!
