Tool Holder Bushings

Somma Tool Company has a large variety of Tool Holder Bushings for CNC and Multi Spindle Machines, available in both metric and fractional ID's and OD's, including HDB series, Type Z and Type C, Type J and Type B, Type LB, LBF, DD, and L series. Somma also has drill holder bushings designed so the bushing grips the drill around three quarters of its circumference resulting in more accurate fitting and line up of the drill and the bushing. The entire length of the bushing firmly clamps the drill shank with less of a chance of the drill being pushed back. Somma Tap Holder bushings and Reamer Holder bushings are designed in the same manner resulting in a more accurate fitting and line up of the tap, or reamer, with the bushing.

Somma Full Floating Adapter Reamer Bushings are used to convert fixed bore reamer holders to a floating type holder for Stub Screw Machine Reamers. Close tolerances can be held without bellmouth because only the reamer floats. Boring Bar Sleeves and Taper Drill Sockets complete Somma's product line of Tool Holder Bushings.
