Sunex Tools 2-Piece Air Hammer Chisel Hinge Pin Driver in Tool Roll (ACS2) provides a targeted solution for one of the more difficult tasks in automotive bodywork: the removal of door hinge roll pins. Standard straight punches often lack the necessary clearance to reach pins without damaging the surrounding door panel or frame. This set addresses that challenge with an angled shaft design that allows the technician to maintain a direct line of force on the pin while the air hammer remains at a safe distance from the vehicle’s body.
Key Features and Benefits:
- Optimized Access: The angled 7.5-inch shafts provide the necessary offset to reach hinge pins located in deep or narrow door recesses.
- Reduced Wear: The patented chamfer design is engineered to extend the life of the chisel by 50% by managing the impact energy more efficiently.
- Corrosion Resistance: A black oxide finish is applied to each driver to provide a barrier against moisture and chemical exposure.
- Pneumatic Compatibility: The .401 shank size ensures that these tools can be used with the vast majority of standard air hammers found in professional shops.
- Organized Storage: The 600D polyester roll pouch protects the tools and keeps them paired together, reducing the risk of losing individual sizes.

- Inspect the Tool: Ensure the .401 shank is clean and free of debris before insertion.
- Insert into Air Hammer: Slide the shank into the air hammer’s retainer and secure it according to the manufacturer’s instructions.
- Position the Tip: Place the tip of the 7.5-inch driver directly against the hinge roll pin.
- Align the Angle: Rotate the tool so that the angled shaft provides maximum clearance from the vehicle’s door panel.
- Apply Pressure: Hold the air hammer firmly and apply steady pressure against the pin.
