170 Piece HSS Drill Bit Set

The Sealey 170 Piece HSS Drill Bit Set is a comprehensive drill bit collection designed for professional tradespeople and serious DIY enthusiasts working with steel, copper and other metals. This extensive set provides fully ground high-speed steel drill bits manufactured to DIN 338 standards, ensuring consistent quality and performance across all sizes. Each drill bit features a 135° split point design that offers self-centring capability, significantly reducing thrust, friction and heat generation during drilling operations. This advanced geometry aids easier penetration through tough materials whilst promoting efficient, clog-free swarf clearance. The bits are suitable for use with both hand-held and pillar drills, making them particularly effective when working with high carbon steels and copper. The set includes a comprehensive range of sizes from 1mm to 10mm in 0.5mm increments, with the most commonly used sizes from 1mm to 8mm supplied in quantities of ten each, whilst larger sizes from 8.5mm to 10mm come with five of each. All drill bits are housed in a tough composite storage case that keeps the collection organised and protected between jobs, making it ideal for mobile tradespeople and workshop environments alike.
