Easy removal: Removing corroded screws is always a headache! Remove damaged screws from damaged workpieces more easily and conveniently with a left-handed bit that works with the Screw Extractor. The screw extractor has a spiral slot that goes deep into the screw for added grip to remove double-headed bolts, screws and studs around the house, garage or work project.

2-in-1 Screw Extractor & Left Hand Drill Bit Set: The set includes 5 pieces of alloy steel screw extractor and 5 pieces of HSS M2 left hand drill bits. Screw extractors include #1, #2, #3, #4, #5.

High-quality cemented carbide material: The left hand drill is made of HSS M2. Compared with ordinary high-speed steel, M2 material can prolong service life, enhance wear resistance, and clear debris. HSS is harder and tougher than other materials.

Unique design: The angle of 118° is easier to cut into the workpiece, and the axial resistance is small. This design can not only increase the length of the cutting edge, but also reduce the nominal thickness of the cutting layer, improve heat dissipation and durability, and have a better cutting effect.

Scope of application：Reverse drill bit extractor set,It is more convenient and easy to remove the broken screw from the damaged workpiece by using the left hand drill bit which coordinates with the screw extractor. Spiral groove on screw extractor can go deep into screw to increase grip force to remove studs, screws and bolts around the house, garage or on your job project.

【High Quality】These 5 piece broken screw remover set is made of high-speed steel with jagged irregular cuts, which can create more extraction possibilities for broken screws or bolts for extra durability and a good lifespan.

【Meet Any Requirement】5 x Broken bolt extractor with magnetic extension screw holder, screw extractor size includes #1 for 1/8"-1/4", #2 for 1/4"-5/16", #3 for 5/16"-7/16", #4 for 7/16"-9/16", #5 for 9/16"-3/4".

【Clever Design】Reverse thread bits spiral design for extra gripping power. Spiral flutes are designed to embed themselves deeper into the metal as you turn the tool, so as the fastener resistance increases, the screw extractor's grip increases.

【Simple to Use】First attach drill bit(Dr) to the extension bit holder, then the drill should be moving the bit counter clockwise(and please use the slow speed), finally use the screw extractor(Ex) side to remove the screw-bolt.
