Professional Fastener Recovery
Precision Extraction Tools Engineered For Extreme Torque
Broken bolts, stripped hex screws, and corroded studs cost industrial facilities, automotive repair shops, and maintenance crews critical downtime. Century Drill & Tool manufactures professional screw extractors and left-hand drill bits engineered to penetrate hardened fasteners and back them out cleanly without galling or damaging internal threads.
Every extraction tool in our lineup undergoes rigorous heat treatment and dimensional inspection. By combining left-hand reverse-cut drill bits with high-taper spiral or straight square splines, our systems deliver the gripping force required to solve the toughest fastener extraction challenges.
- Heat-Treated Chrome Vanadium Steel: High torsional resistance prevents snapping under intense pressure.
- Reverse Left-Hand Flute Geometry: Drilling motion often backs out broken bolts before extraction tools are needed.
- Spiral vs. Square Spline Options: Designed for high-torque solid studs or delicate thin-walled pipe fittings.
- Commercial & Distributor Packaging: Supplied in heavy-duty index boxes, molded cases, and blister packs ready for retail display.

Extractor Selection Guide By Fastener Condition
Selecting the correct extraction geometry prevents bit breakage and internal thread damage. Use our engineering guidelines below to match tool design to your specific repair application.
| Extractor Style | Core Geometry | Material / Alloy | Recommended Fasteners | Operational Advantage |
|---|---|---|---|---|
| Spiral Flute Extractor | Tapered left-hand spiral thread | Heat-Treated Cr-V Steel | Seized, rusted, or frozen studs & bolts | Bites deeper into broken shank as turning torque increases. |
| Square Flute Extractor | Straight, 4-point vertical splines | Hardened Alloy Steel | Thin-wall fittings, socket cap screws, soft alloys | Prevents outward wedge pressure, preserving internal sleeve threads. |
| Left-Hand Drill Bits | 118° split point, reverse spiral | M2 High Speed Steel (HSS) | Sheared bolts, flush-broken fasteners | Reverse cutting action frequently backs out broken screws during pre-drilling. |
| Damaged Screw Removers | Dual-ended burnisher & reverse cone | Hardened Tool Steel | Stripped Phillips, Torx, Slotted wood/deck screws | Compatible with power driver quick-change chucks for rapid extraction. |

Engineering Insights
Frequently Asked Questions
Spiral flute extractors feature left-hand spiral grooves that draw themselves deeper into the drilled hole as counter-clockwise torque increases, providing maximum grip for heavy-duty rusted bolts. Square flute extractors feature straight splines that bite without exerting outward expansion force, making them the safest choice for thin-walled pipe fittings or soft aluminum housings.
Left-hand drill bits rotate counter-clockwise. While creating the required center pilot hole, the bit's cutting edges and heat generation often catch the broken bolt shank and unscrew it automatically, eliminating the need to use an extractor bit altogether in up to 40% of cases.
Our professional extractors are forged from high-grade Chrome Vanadium (Cr-V) steel or premium tool steel, heat-treated to HRC 58-62 hardness. Our left-hand drills are manufactured from premium M2 High Speed Steel (HSS) to ensure clean cutting into grade 5 and grade 8 fasteners.
