Standard GEN2 SeriesDrilling| Powder coated High-speed steel, Coated carbide inserts

Large diameter and ultra-deep machining
Select the chipbreaker based on the workpiece material

Inserts achieve stable cutting performance with highly effective edge design and excellent wear resistance

Tooling selection supports hole machining diameters of "φ9.5 to φ114"
and maximum machining depth of "32D"

Features

  • Excellent chip control
  • Fragments chips with notch and unique chipbreaker designs
  • Coolant supplied to the tool tip evacuates the chips from cutting area and cools cutting edge
  • No step feed requirements to break chips

153mm/min

Competitor's HSS drill

41mm/min

By eliminating step feed, the machine time was reduced to less than 1/11th of the original machine tools.
There was also 3.7 times higher machining efficiency compared to the conventional tool.

Metal die for plastic (φ18×200mm, 11D)
Material :

162mm/min

Competitor's HSS solid drill

35mm/min

In addition to improving the machining efficiency by 4.6 times compared to the conventional tool, the machining time has been reduced to 1/8 or less by eliminating the step feed.
It has achieved the same life as conventional tools and is currently undergoing continuous testing.
