Metal Drill Bit Set 10 pcs Split Point 135 Degrees 1–3 mm HSS M35 with 5% Cobalt Gold For Metal and Stainless Steel Higher Heat Resistance
You already have the maximum available quantity in your cart.
The metal drill bit set includes 10 pieces of high-speed steel HSS M35 with a 5% cobalt alloy, which provides better resistance to the heat generated during drilling. The bits cover diameters from 1 to 3 mm, allowing you to choose the appropriate size for most common tasks. Each bit features a split point with a cutting angle of 135 degrees, which prevents slipping on smooth surfaces and ensures more accurate drilling. The set is designed for metal and stainless steel, materials where standard drill bits quickly lose sharpness. The gold finish is characteristic of cobalt drill bits, making them easily distinguishable from others in the workshop.
A key feature is the cobalt alloy, which enhances the thermal resistance of the material. When drilling into stainless steel, high temperatures are generated, and a standard HSS drill bit quickly dulls – the cobalt alloy maintains sharpness longer. The split point at 135 degrees also reduces the required pressure and does not require pre-drilling with a centre punch. The set contains two pieces of each size, so you have a spare on hand if one drill bit gets damaged. The bits have varying overall lengths depending on the diameter – from 34 mm for the 1 mm size up to 60 mm for the 3 mm size.
You can use the bits for drilling into steel, stainless steel, cast iron, brass, and aluminium, making them suitable for common locksmithing and maintenance tasks. Smaller diameters are ideal for drilling holes for screws, rivets, and small assemblies. It is recommended to drill at lower speeds and use cooling or cutting oil, which will extend the life of the bit. The material should be securely clamped before drilling to prevent the bit from breaking. The set is appreciated by both professionals and DIY enthusiasts in home workshops.
