The Foredom H.43T is the same handpeice as the H.44T but one inch shorter in length. The H.43T comes with three collets 3/32" (2.35mm), 1/8" (3.18mm) and 1/4" (6.4mm) and pin and chuck wrench. Other fractional and metric collets are available separately and in collet set 440. Can be used in Foredom's handpiece holder, but is too short for use in drill presses. 4-1/2" long by 1" diameter.
