Product Description

YG-1 DH421 Dream Drills are TiAlN-coated solid carbide 8XD coolant-hole drills for deep holes. They drill steel, cast steel, cast iron and malleable cast iron using internal coolant delivery. R-thinning supports self-centring and chip breaking, helping establish controlled entry in extended-reach drilling. The wave-shaped cutting edge and negative land are designed for low thrust and stable torque.

An optimised flute shape provides drilling strength and supports smooth chip evacuation. Extra-long 8XD geometry suits extended-depth holes where coolant must reach the cutting zone. DH421 diameters span 3.0 to 14.0 mm, with m7 shank tolerance throughout the series. Specified shank diameters range from 6 to 14 mm across available drill sizes.

  • TiAlN-coated solid carbide drill construction
  • Internal coolant holes for 8XD deep-hole drilling
  • R-thinning supports self-centring and chip breaking
  • Wave-shaped cutting edge and negative land support low thrust and stable torque
  • Optimised flute shape supports drilling strength and smooth chip evacuation
