Holesaw 378

Dramatically improved drilling efficiency and cost effectiveness thanks to the Poly-Clic system.

Drimond Core Bit

CHARACTERISTICS
  • The carbide-tipped teeth have realized drilling in work materials such as stainless steel.
  • Easily bores a hole in work materials of up to 5/32" (4mm) in thickness.
  • By attaching this tool to an electric drill with high rotational speed, much faster drilling is possible compared to high speed steel cutters.
    1. The cutting depth can be set in consideration of safety.
    2. A safety stopper with this tool stops the cutter from moving forward even after penetration.
APPLICATIONS
  • Mild steel plates, stainless steel plates, copper plates, etc. and curved surfaces.
  • Work materials such as FRP and resin plates.
