Highlights
- 【Stripped Screw? Removed!】This easy out screw extractor set with left hand drill bits is specifically designed to remove stripped, broken, or damaged screws, studs, bolts, and fasteners — which cannot be removed with standard screwdrivers or wrenches, whereas hardened steel left‑hand drill bits can easily handle screws made from carbon steel, cast iron, copper, aluminum, and other similar materials.
- 【Tough & Break-Resistant】The left-hand drill bits are made of 6542 HSS (High-Speed Steel), offering hardness up to 63 HRC, better toughness, and resistance to high temperatures during high-speed cutting. The 135° split-point design makes drilling easier and reduces axial resistance. The extractors are made of 35# CR-MO steel, significantly enhancing strength, toughness, and heat resistance for long-lasting durability.
- 【Multiple Use Scenarios】This reverse screw extractor kit is a sturdy kit built for frequent, heavy-duty removal of broken screws — ideal for automotive shops, factory maintenance, construction sites, and mold repair. Covering most common industrial and household screws from M3 to M18, it's perfect 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.
- 【Non‑Applicable Screws】Our left-hand drill bits have a hardness of HRC 63–66. They cannot handle extremely hard “top-tier” or higher-grade alloy/stainless steel screws, such as 440 series stainless steel. And this reverse drill bit set is designed for left-hand (counterclockwise) rotation. When drilling, set your power drill to counterclockwise rotation. A slower speed makes screw remov'al easier; high speed requires precise control to avoid bit wandering or breakage.

Detailed Review
The FMENTOOLS 15-Piece Stripped Screw Extractor Set provides a practical solution for removing seized, stripped, or broken fasteners that standard screwdrivers and wrenches cannot budge. Designed to handle hardware ranging from M3 to M18, it suits auto mechanics, factory technicians, and home DIYers tackling stubborn bolts, studs, and screws in automotive shops, construction sites, or home workshops.
Drilling out stuck hardware requires dependable cutting tools, and this set uses left-hand drill bits made from 6542 High-Speed Steel with a hardness reaching 63 to 66 HRC. These bits feature a 135-degree split-point design to reduce axial resistance and cut smoothly into materials like carbon steel, cast iron, aluminum, and copper. The kit also includes a center punch, which lets you create an accurate starting point so the drill bit will not walk or slip off center.
Once a pilot hole is drilled, the spiral flute extractors take over. Made from 35# CR-MO steel, these extractors provide the strength, toughness, and heat resistance needed to bite into damaged fasteners and back them out. The 15-piece assortment includes seven left-hand drill bits (1/8 inch, 5/32 inch, 3/16 inch, 1/4 inch, and 19/64 inch, with duplicates for the two smallest sizes) and seven matching spiral extractors (#1 through #5, with duplicates for #1 and #2), all housed in a sturdy storage case.
While versatile, the set has clear limits. The 63 to 66 HRC hardness means these tools cannot drill into extremely hard alloy steels or higher-grade stainless steels, such as the 440 series. Users also need to operate their power drills in counterclockwise rotation at slower, controlled speeds, as high drilling speeds can lead to bit wandering or tool breakage.
Verdict: This set is a solid choice for mechanics and DIYers who frequently need to extract stuck or stripped fasteners made from standard metals. As long as you work at slower drill speeds and avoid hardened stainless alloys, it provides all the essential sizes and extraction tools in one organized kit.

Who Should Buy It
A great fit if you:
- Need to remove stripped, damaged, or broken fasteners between sizes M3 and M18.
- Work on automotive parts, machinery, mold repairs, or home DIY projects made from carbon steel, cast iron, copper, or aluminum.
- Want duplicate sizes for frequently used smaller drill bits and extractors.
- Appreciate having a center punch included to mark your starting spot.
Consider something else if you:
- Regularly work with high-grade alloys or 440 series stainless steel fasteners.
- Do not have a reversible power drill that can operate counterclockwise at slow speeds.
FAQ
Which direction should my drill spin when using these bits?
Your power drill must be set to counterclockwise (left-hand) rotation. Running the drill at slower speeds makes removal easier and prevents bit wandering or breakage.
What types of metal can this extractor set handle?
The drill bits can cut into screws and fasteners made from carbon steel, cast iron, aluminum, and copper. They are not designed for very hard alloy steels or higher-grade stainless steels like the 440 series.
What pieces are included in the 15-piece kit?
The set contains 1 center punch, 7 left-hand drill bits (two 1/8 inch, two 5/32 inch, one 3/16 inch, one 1/4 inch, and one 19/64 inch), 7 spiral flute extractors (two #1, two #2, one #3, one #4, and one #5), and a storage case.
