Description

Key Features

• Black oxide coating prevents rust
• Tapered web eliminates the frustration of bit spinning in the chuck
• Patented core diameter reduces breakage

Black oxide coated for greater wear resistance with 3/8 inch shank and 31 degree helix minimizes the over aggressiveness of its true 135 degree parabolic flute. Split point for quicker starting & no walk applications, parabolic flute design improves chip ejection in metal & wood drilling applications, back oxide coating for greater resistance to wear, industrial grade steel, for drilling in metal, wood & plastic.

135 deg split provides greater durability to reduce breaking. Black oxide coated for greater wear resistance; split point drills on contact and prevents walking. Parabolic flute design improves chip ejection in metal and wood drilling applications. Helix is 31 degrees which minimizes the over aggressiveness of a tru e parabolic flute.
