Product Number: AK8191
Variations
A snapped stud or broken screw buried in an engine block or component can quickly become one of the most time-consuming problems in the workshop. The Sealey AK8191 Left-Hand Spiral Drill Bit Set provides a 25-piece professional solution, with bits engineered to rotate in reverse so that as they cut into a broken fastener the reverse action simultaneously works to unthread and release it. Manufactured from 4241 HSS steel, the set covers diameters from 1mm to 13mm in precise 0.5mm increments, offering broader coverage than the 19-piece AK8190 and making it the stronger choice for tackling larger snapped studs and fixings. The 118° split-point tip bites into the workpiece quickly without wandering, reducing the need to centre-mark before drilling. Sizes included are 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, 10.5, 11, 11.5, 12, 12.5 and 13mm. The set arrives in a powder-coated metal storage case with internal organisers for neat, secure storage.

A. Left-hand drill bits rotate in reverse, making them specifically suited to extracting snapped studs, screws or fixings. The reverse cutting action often unthreads the broken fastener as the bit cuts into it, releasing it without the need for a separate extractor tool.
A. The set includes Ø1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, 10.5, 11, 11.5, 12, 12.5 and 13mm.
A. The bits are manufactured from 4241 HSS (high-speed steel).
A. The 118° split-point tip allows the bit to bite into the workpiece quickly and accurately, minimising the need to centre-mark the surface and reducing the risk of the bit drifting off-centre during drilling.
