FOR USE ON AIRCRAFT STYLE DRILLS - Ideal for use in Kimball Midwest's Mini Pneumatic Right Angle Aircraft Style Drill (82-342). Used in the aviation and aerospace industries for drilling out rivets and machine screw holes where limited clearance is available.
SHORT PATTERN - Reduced overall length bits are designed for confined areas.
THREADED SHANK DESIGN - Shanks are constructed with 1/4-28 threads and an integrated square hex nut for fast and easy mounting.
SPLIT POINT DESIGN - Super heavy duty 135° split point eliminates center punching and prevents "walking" of the bit.
DURABLE - National Aerospace Standard (NAS) high speed steel construction provides superior service life.
