HSS construction aims for repeatable performance during routine drilling. Straightforward geometry suits workshop and site use where consistent holes are needed.
Versatile material compatibility, with HSS construction
HSS is specified in the product name, suitable for cutting a wide range of materials. Flute length of 78mm and an overall length of 150mm give adequate engagement for many common drilling tasks.
Reliable cutting in aluminium, steel, timber and plastics reduces the need to swap bits. Suitable for bracket work, panel holes and general workshop drilling.
Secure chuck compatibility, thanks to reduced 12.7mm shank
Shank diameter is 12.7mm, smaller than the 20mm cutting diameter, so the bit fits most standard drill chucks. Reduced shanks allow larger cutting diameters to be used with widely available chucks.
No need for specialised large-capacity chucks, which simplifies use with hand drills and bench drills. Saves time on jobs where chuck capacity would otherwise be a limitation.
