Features

Hi-PerCarb® Series 146U / 136U Flat Bottom Drill End Geometry Image

ECCENTRIC 4-MARGIN DESIGN

  • A unique coolant channel design allows repositioning of the trailing margins for improved stability over conventional two and four margin drills
  • Eccentric style clearance reduces margin contact with the workpiece without reducing strength

END GEOMETRY

  • The primary only relief allows the trailing margins to help stabilize the drill up to three times faster than conventional designs
  • High shear corner geometry minimizes exit bur
  • Computer controlled edge hone protects against edge chipping in difficult applications

COOLANT CHANNELS

  • The two-channel design provides additional coolant in the hole when thru-tool coolant is not available

Coating

Ti-Namite-x hard coating logo

Combine to minimize material adhesion and maximize wear resistance in a wide range of workpiece materials.
