Cobalt Drill Bit Set 3.5mm 10pc HSS 5% Co Twist Drills for Metal

A 10-piece set of 3.5mm twist drill bits made from HSS with 5% cobalt for drilling metal and other tougher materials. Useful when you need the same hole size repeatedly, these bits are a practical choice for keeping spares ready rather than relying on a single drill bit.

Used for workshop jobs, garage work, site work and home maintenance, this cobalt drill set suits anyone carrying out repeated drilling where a 3.5mm bit gets regular use. Handy for vehicle maintenance, fabrication, fitting work and general DIY repairs, especially when tougher materials can wear out a basic bit more quickly. Having 10 matching bits also helps keep the job moving if one becomes blunt or damaged part way through.

The set includes 10 identical 3.5mm bits, so you have a consistent size across the whole job without mixing different diameters. HSS construction makes them suitable for regular drilling work, while the 5% cobalt content helps with wear resistance when working on more demanding materials. For anyone who uses this size often, keeping several matching bits close to hand is useful for repeated work and helps avoid unnecessary interruptions between tasks.
