Description
Overview:
The Sealey AK8189 Left Hand Spiral Drill Bit Set is a 5‐piece kit designed for drilling in reverse to help release and extract snapped studs, broken screws, and stubborn fixings. Manufactured from high‐quality 4121 HSS steel for durability and clean cutting, the bits work anti‐clockwise when your drill is set to reverse. This action often bites into, loosens, and turns out damaged fasteners as you drill. Supplied in a compact storage case, the set covers common sizes for workshop, automotive, agricultural, and construction maintenance. Use with corded or cordless drills, or a drill press with reverse. It is a practical choice for mechanics, engineers, and DIY users tackling repair jobs on machinery, vehicles, plant equipment, and garden tools.
Key Features:
- Left‐hand spiral for effective reverse drilling and assisted fastener removal
- Made from 4121 HSS steel for strength, wear resistance, and consistent performance
- Five sizes: 3.2 mm (1/8"), 4.8 mm (3/16"), 6.4 mm (1/4"), 8.0 mm (5/16"), 8.7 mm (11/32")
- Suitable for use with most handheld drills and drill presses that have a reverse function
- Helps to loosen and extract broken studs and screws as the bit bites counter‐clockwise
- Neat storage/display case keeps bits organised and protected in the toolbox or van
- Useful preparatory step before using stud/screw extractors on seized fasteners
- Balanced sizing range covers many everyday repair and maintenance tasks
Typical Applications:
Removing broken bolts from engine blocks, housings, brackets, and casings; backing out snapped screws from bodywork, panels, hinges, and clamps; freeing seized fixings on construction equipment, plant, trailers, and agricultural or garden machinery; drilling pilot holes in reverse to reduce further tightening of damaged threads.
