## Description

The DeWalt 29 Piece HSS E Cobalt Drill Bit Set is a professional-grade metal drilling solution, engineered for demanding applications across a comprehensive range of sizes from 1mm to 13mm. With an 8% cobalt content throughout each bit, this set maintains a sharper cutting edge for longer, delivering 4x the working life compared to standard DeWalt Black Oxide bits. This makes it a sound investment for contractors, engineers, and fabricators regularly working with tough metals such as stainless steel and hardened alloys. The optimised tip and flute geometry achieves 2x the penetration speed versus Black Oxide equivalents, removing swarf more efficiently and reducing heat build-up at the cutting zone. A stronger central core also provides 2x the resistance to breakage , reducing the risk of bit failure during heavy-duty drilling tasks. Supplied in a durable plastic storage case, the 29-piece range covers a practical spread of metric and fractional sizes, ensuring you have the right bit to hand for clearance holes, tapping sizes, and precision applications without reaching for a separate set. Features and Benefits: • 8% cobalt content for a sharper cutting edge and extended bit life • 4x longer life versus DeWalt Black Oxide drill bits • 2x faster penetration speed for increased productivity on site • Optimised flute geometry reduces heat build-up and removes material faster • Stronger central core delivers 2x the resistance to breakage • 29 sizes from 1mm to 13mm covering a wide range of drilling applications • Supplied in a plastic storage case for organised, protected transport and storage Contents: 1mm Drill Bit 1.5mm Drill Bit 2mm Drill Bit 2.5mm Drill Bit 3mm Drill Bit 3.2mm Drill Bit 3.3mm Drill Bit 3.5mm Drill Bit 4mm Drill Bit 4.2mm Drill Bit 4.5mm Drill Bit 4.8mm Drill Bit 5mm Drill Bit 5.5mm Drill Bit 6mm Drill Bit 6.5mm Drill Bit 7mm Drill Bit 7.5mm Drill Bit 8mm Drill Bit 8.5mm Drill Bit 9mm Drill Bit 9.5mm Drill Bit 10mm Drill Bit 10.5mm Drill Bit 11mm Drill Bit 11.5mm Drill Bit 12mm Drill Bit 12.5mm Drill Bit 13mm Drill Bit Plastic Case
