- 【Broken Screw & Bolt? Removed!】When you encounter stripped, broken, or damaged screws, bolts, studs, or fasteners that standard screwdrivers or wrenches can't remove, our easy out screw extractor set with left-hand drill bits makes removal easy—simple, time-saving, and effortless.
- 【Tough & Break-Resistant】These left-hand drill bits are made of 6542 HSS, offering better toughness and resistance to high temperatures during high-speed cutting. The 135° split-point design makes drilling easier and reduces axial resistance. And the bolt extractors are made of 35# CR-MO steel, offering good strength, toughness, and long-lasting durability.
- 【Multiple Use Scenarios】This broken bolt extractor kit is designed to remove damaged screws, bolts, and fasteners from wood or metal—ideal for automotive repair shops, factory maintenance, construction sites, and mold repair. Covering most common screws from M3 to M18, it’s suitable for auto mechanics, industrial technicians, and home DIY enthusiasts.
- 【10+4+1 Professional Set】This 15‐piece easy out bolt extractor set includes: 1 center punch for precise starting point marking to prevent bit walking and slipping; 7 left‐hand drill bits in sizes 1/8", 1/8", 5/32", 5/32", 3/16", 1/4", and 19/64"; and 7 spiral flute extractors in sizes #1, #1, #2, #2, #3, #4, and #5. All tools are stored in a durable, sturdy storage case to prevent loss.
- 【Extractor Set Usage Notes】Our left-hand drill bits feature a hardness of HRC 63–66. They cannot handle extremely hard alloy or stainless steel screws, such as 440 series stainless steel. This reverse drill bit set is designed for left-hand (counterclockwise) rotation. When drilling, set your power drill to the counterclockwise setting. A slower speed makes screw removal easier; high speed requires precise control to avoid bit wandering. For smoother removal, apply cutting fluid.

Select a product to estimate shipping.What Kinds of Screws Can Our Left-Hand Drill Bits Drill Through?
6542 HSS, with hardness HRC 63-66, is a general-purpose high-speed steel. It can easily handle metals with hardness below HRC 30, such as ordinary carbon steel, cast iron, copper, and aluminum.
What Kinds of Screws Can Our Left-Hand Drill Bits Not Drill Through?
Not suitable for drilling SAE Grade 8, ISO 10.9/12.9, or harder fasteners
1.Extremely hard screws (quenched/heat-treated steel) can reach HRC 50+.
2.Higher-grade alloys like 440 series stainless steel.
So standard HSS drill bits won't work well.
What Is the Green Center Punch Used For?
Broken/stripped screws are smooth, so drill bits slip. Tapping the center punch with a hammer creates a center indent for accurate drilling, preventing wandering and protecting threads. Ensures alignment for removing stuck screws counterclockwise.
What Are the Precautions for Using the Screw Extractor Set and Left-Hand Drill Bit Set?
1. When using an HSS twist drill bit, set the drill to low speed for easier and smoother drilling into the screw.
2. Both the twist drill and the extractor rotate counterclockwise. When using an electric drill, set it to the reverse rotation.
When Should You Stop Drilling?
If drilling feels unusually difficult or produces a high-pitched noise, stop immediately—this usually indicates that the material is too hard for the drill bit.
