LONGER TOOL LIFE : Engineered with 5% cobalt alloyed High Speed Steel, these bits deliver exceptional durability for demanding site applications. UP TO 4X LONGER LIFE : Outlasts standard HSS-R metal drill bits, reducing replacement frequency and maximising jobsite productivity. PRECISION ENTRY : Features advanced tip designs: split point tips (1–3mm) for rapid, accurate entry; optimised pilot points (3.2–8mm) for fast starts; and a new multistep point (8.5mm+) for unrivalled accuracy and zero bit walking. ULTIMATE VERSATILITY: Suitable for both portable and stationary drilling in high alloy steels and metals with tensile strength up to 1100N/mm², ensuring flexibility across applications. NO SLIP PERFORMANCE : The spin-proof, three-sided shaft guarantees optimal grip in the drill chuck, preventing slippage during intensive use. TOUGHER CORE DESIGN :Reinforced central core thickness towards the chuck enhances fracture stability, especially during freehand operation. FASTER DRILLING SPEED : Optimised tip and flute geometry deliver up to 4X faster penetration compared to standard HSS-R drill bits, accelerating your workflow. IDEAL FOR HARD METALS: Designed for superior performance on tough materials including bronze, cast iron, stainless steel, and titanium, meeting the demands of professional trades INCLUDE: HSS-E Cobalt Metal Drill Bit: 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.2mm, 3.3mm, 3.5mm, 4mm, 4.2mm, 4.5mm, 4.8mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, 10.5mm, 11mm, 11.5mm, 12mm, 12.5mm, 13mm Compatible with: DCD701D2-QW, Weight: 0.719 pounds, Manufacturer: AmazonUk/3K3AF
