The Hammer Core Pilot is used to make an initial starting groove and is then removed before further drilling is continued. Hammer core pilot bits are interchangeable with hammer core bodies from 1-1/2” diameter through 6” diameter. (The hammer core pilot drill will not fit 1” diameter through 1-1/4” diameter core bodies.)

Percussion / Hammer Core Extensions

PDE Series Extensions have 3/4-10 female threaded ends. These extensions fit the Percussion Core drive shanks. (They cannot be used with PC9888 or PC9999.)

Percussion / Hammer Core Adapters

Percussion core bit shank adapters have a replaceable 3/4-10 threaded coupler for an extra long working life. You need only replace the threaded adapter if it should wear or break. Due to changes and additions in power tool models, other adapters may be available, but not listed.
