STONE REEF Professional Screw Extractor Set [5 Pieces Made of HSS 4241] Left Professional, Extractor, Tool, Hand Turner Set, Remover, Drill

COMPATIBILITY & BOLT SIZES: 5-piece professional easy out set for common thread sizes. Suitable for extracting screws and bolts from M3 to M18 (1/8" to 3/4"). Precision-ground square drive compatible with tap wrenches, die stocks or matching sockets. Designed to remove stripped hex, Torx or slotted fasteners without damaging the internal thread. MATERIAL & BUILD QUALITY: Manufactured from high-alloy HSS 6542 (M2) High Speed Steel. Offers significantly higher hardness and heat resistance compared to standard carbon steel (GCR15) extractors. Specialized heat treatment ensures maximum torsional strength and prevents snapping when high torque is applied to seized or rusted components. PERFORMANCE & GRIP: Aggressive left-hand spiral design with conical geometry for superior bite. The sharp cutting edges dig deep into the pre-drilled bolt during counter-clockwise rotation, ensuring a non-slip grip. Effective for removing sheared-off screw heads, recessed bolts and stubborn manifold studs. APPLICATION & USAGE: Straightforward 3-step extraction: 1. Drill a pilot hole in the centre of the broken bolt using a suitable HSS drill bit. 2. Insert the correct size extractor into the hole. 3. Turn anti-clockwise using a tap wrench. The precision-fluted taper minimizes bolt expansion, preventing further jamming. DURABILITY & SET ADVANTAGE: Industrial grade for daily use in automotive workshops, engineering and home maintenance. This set covers the most frequent diameters, preventing costly downtime. Supplied in a heavy-duty storage case for quick selection and protection of the cutting flutes during transport., Manufacturer: STONE REEF
