Body Drills

High Speed Steel & Cobalt
Body Drills are intended primarily for use in hand held, air, or electric drill
motors, in sheet metal, thin wall tubing, or any other shallow hole drilling.
HOLE MAKING Single End
Because of their short flute design and heavy web construction, they are
considerably more rigid and durable than Jobber or Screw Machine lengths.
Breakage is significantly reduced or eliminated and tool life is greatly increased.

List No. 650S – Style S, 135° Split Point
Used in hand or machine drilling without guide bushings, and where
burring is not a problem. This point centers quickly and may be used
successfully in tougher, harder materials.
List No. 650F – Style F, Fishtail Point
Used in hand drilling thin material or machine drilling where the ratio of hole
size to material thickness is very large, and where burr free holes are desired.
A guide bushing must be used to center the drill point.
