Screw and bolt extractor set – includes 5 left hand drill bits and 5 screw extractor bits that range in size for removal of most common size screws and bolts. A metal case is included to store all 10 bits. Each size is clearly labelled on both the case as well as the bits themselves. Drill bits are titanium coated and made of HSS4241 (tough, high speed steel), and the screw extractor bits are made of GCr15 (high quality carbon steel). The left-hand drill bits are designed to drill in a counter-clockwise direction so that the screw or bolt you are removing will not tighten further. Once a small hole is drilled into the screw or bolt, the matching extractor bit can be tapped into the hole with a hammer and then can be attached to a tap handle, wrench, or inserted into a drill. Left-hand Drill bit sizes are: 5/64″, 7/64″, 5/32″, 1/4″ and 19/64″ Extractor bits are: M3-M4 #1 (3/32″ – 5/32″), M4-M5 #2 (5/32″ – 7/32″), M5-M7 #3 (7/32″ – 9/32″), M7-M9 #4 (9/32″ – 3/8″), and M9-M15 #5 (3/8″ – 5/8″) Full instructions: 1. Preparation: a. Ensure that the work piece is secure and will not move during the use of this tool b. Insert drilling bit directly into drill or quick change chuck c. Change drill direction to reverse d. Place the bit onto the center of the damaged screw/bolt, activate the drill and apply pressure toward the screw/bolt. Stop when a 1/16″ deep area has been drilled into the center. 2. Extracting: a. Hold the matching extractor bit in the hole in the screw/bolt and use a hammer or mallet to drive the extractor threads into the screw/bolt. b. Attach the bit to a tap handle, wrench, or drill c. Rotate the bit counter-clockwise (or drill at a low speed in reverse) while applying downward pressure – the extractor will thread into the screw/bolt head and remove the screw/bolt. Maintenance: Clean debris off of the bit and use oil to lubricate after each use.
