The Greenfield Drill Chuck - Automobile Dealer and Repairer, Vol.19, March 1915

Manufactured by the Goodell Manufacturing Company, Greenfield, Mass., this is a strong, accurate, and well made drill chuck at a popular price, and it is especially adapted for use in automobile garages and repair shops.

The shell is one piece, and the jaws are of tool steel, carefully hardened and tempered. It has ball-bearing thrust, and the thread of the shank being concealed, there is no chance for it to become bruised or injured.

The bearing in the Greenfield Drill Chuck is in the center of the shell, which produces an accurate and more reliable chuck than when the bearing is at the extreme rear.

The chuck has such a strong grip that no spanner wrench is required to tighten, but one is furnished with the two larger sizes, as occasionally one is needed to loosen.

The shank forms part of the chuck, making it complete, ready for use. For prices and full particulars write to the Goodell Manufacturing Company, Greenfield, Mass.
