All American(r) Drill Bushing Tips provide a fast, accurate method for portable/stationary mounting of drilling, tapping and other self-contained machining units on a jig/fixture. The threaded end of the drill bushing tip screws into the nose end of the drilling unit. The helical flanges on the tip fit under the shoulders of the lock screws/lock strips on the jig, effectively holding the drilling unit in alignment position and absorbing drilling thrust and torque.
All American(r) Drill Bushing Tips are finished to order to the drill size specified by the user. They are available for applications from No. 70 drill up through 1-15/32" diameter.
Drill guide hole finished to ANSI specifications/customer's exact dimensional requirements.
Chip clearance hole prevents jam-up of chips. Chips work back into the nose piece and out slots in sides of nose piece.

Drill bushing tips are constructed by a two--piece method consisting of a collar and a pressed-in shank. The collar contains the screw threads, alignment diameter and the lock flange. The shank contains the A, B, and dimensions listed in the chart. Maximum and minimum drill sizes (A) for drill bushing tips are shown in the column headings of the chart. Collars/shanks only of two-piece drill bushing tips may be ordered separately for replacement purposed: (See "ordering Information.")
Collar and threads are heat treated to produce strength and provide wear resistance. Shank is hardened for maximum wear resistance.
Marked with part number and drill size for easy identification and simplicity in reordering.
Precision ground shank, with entering bevel for easy insertion in lock liner bushing.
Collar has blackened finish for resistance to rust and corrosion.
