M35 Cobalt Step Drill Bit 3-13mm (11 Steps) Hex Shank - For Metal, Wood, Plastic, Spiral Groove Design

Tackle a whole range of hole sizes with just one bit! This M35 Cobalt Step Drill Bit is a powerhouse tool for DIYers and pros alike. It features 11 precision steps from 3mm all the way up to 13mm, so you can drill perfectly sized holes for pipes, cables, or fittings without switching bits constantly. It's made from premium M35 cobalt high-speed steel with an AlTiN coating, giving it extreme hardness (89HRC) and heat resistance. This means it chews through tough materials like stainless steel, mild steel, and aluminum way better than standard HSS bits. The clever spiral groove design helps pull metal shavings and chips out of the hole as you drill, keeping things clean and preventing clogging for smoother, faster cuts. The 118-degree split point starts drilling exactly where you want it, preventing the bit from 'walking' on the surface. It has a universal 1/4-inch (6.35mm) hex shank that fits securely into all standard drill chucks, impact drivers, and drill presses. Remember to use a little cutting oil when drilling metal to keep things cool and extend the bit's life. It's perfect for metalworking projects, woodworking, plumbing, electrical work, or any home DIY job involving sheet metal, wood, plastic, or PVC. A true multi-material workhorse that saves time and space in your toolbox.
