Impact Wrench Extractor and Drill Bit Sets
 |  |
All the tools you need to quickly remove various sizes of the most stubborn bolts. Made with an oversized shank and hardened steel, the bits and extractors in these sets are built to handle the high torque of impact wrenches without snapping. Drill a pilot hole with the left-hand drill bit, then insert the extractor. The part will back out without damaging the threads around it. They work well even in hard materials like stainless steel.
You’ll need a VersaDrive chuck (sold separately) to install the drill bits and extractors into your impact wrench. You can also get chucks for impact drivers and magnetic-base drills (both sold separately). For jobs that don’t require the torque of an impact tool, you can fit these drill bits and extractors directly into a 1/2" chuck on a standard power drill.

These chucks mount directly onto the square drive of your impact wrench. They work with any tool with a VersaDrive hex shank, so you don’t need to swap chucks to use drill bits, taps, and other tools.
Quick-Change Pull-Back Tool Release—Require just one hand to load. Push your tool in the chuck until you hear the ball detents click into place. To remove your tool, pull back the collar.
Strong-Hold Push-Forward Tool Release—Hold cutting tools more securely than quick-change chucks. To insert and remove cutting tools, you must push a collar forward. Since impact force drives your cutting tool the opposite way, it can’t come loose from the chuck while you work.
Manganese Phosphate-Coated Steel—The coating on these chucks prevents rust.

Impact Wrench Left-Hand Cobalt Steel Drill Bits
 |  |
Use high torque to drill pilot holes in broken bolts and seized studs to prep them for extraction. Made with an oversized shank and hardened cobalt steel, these bits are built to handle the power of your impact wrench without snapping, even in large holes and hard materials such as stainless steel. The flutes spiral in the opposite direction of other bits, so they loosen stubborn fasteners as you drill. To use them, set your impact wrench to reverse. Once you have a pilot hole, use the matching extractor (sold separately) to back the fastener out. You may need to punch a starter hole in badly stripped screws before drilling. Also known as reverse-flute bits.
You’ll need a VersaDrive chuck (sold separately) to install these bits into your impact wrench. You can also get chucks for impact drivers and magnetic-base drills (both sold separately). For jobs that don’t require the torque of an impact tool, you can fit these bits directly into a 1/2" chuck on a standard power drill.
Short Length—The most rigid bits for drilling the straightest holes.
Titanium Aluminum Nitride (TiAlN) Coated—The hardest and most wear-resistant coating, especially at high temperatures. These bits are best for hard and abrasive materials, such as iron, titanium, and fiberglass.
