Blue-Point's XL Air Hammer Drift Set, No. PHGL37KT, can break free hard-to-reach bolts and pins that have seized due to rust and time. Designed for suspension work where rusted shock and strut bolts cannot be accessed with conventional length punches and tapered drifts. The drifts provide extra driving force of an air hammer where needed and its 5" long parallel shaft design does not get stuck in deep holes. The set includes the three most commonly used sizes (8 mm to 5/16-inch, 10 mm to 3/8-inch and 12 mm to 1/2-inch) and a canvas pouch for storing.
