The A1-C and A2-C drill frames for dowel drilling have been redesigned with a 7-in. shorter wheel base, allowing for a tighter turning radius and is approximately 30 lbs lighter than previous models. Features include an automatic shut-off that stops the drill from absorbing the abuse of dry firing, which greatly extends the life of the drill. The company has also released new pistol grip control handles for the A-1-36 and A-1-48 on-grade dowel pin drills units. Releasing the handles will stop the drill instantly, creating a much safer drilling environment. Minnich Mfg.
