Cobalt Drill Bit Set 4.5mm 10pc HSS 5% Co Twist Drills for Metal

A 10-piece set of 4.5mm twist drill bits made from HSS with 5% cobalt for tougher drilling jobs. This twist drill bit set is a practical choice when you regularly use 4.5mm bits and want matching spares ready to hand for repeated work.

Used across workshop, garage and site jobs, these cobalt bits suit anyone drilling tougher materials where a standard bit may wear sooner. They are useful for regular fabrication, repair work, fitting tasks and general maintenance, especially when 4.5mm is a common size in your day-to-day work. Keeping a dedicated pack of the same size also helps when you are working through repeat jobs and do not want to stop midway to search for a replacement.

The set includes 10 matching drill bits, each sized at 4.5mm, so it is straightforward to keep one size together and ready for ongoing use. HSS construction with 5% cobalt makes them better suited to tougher materials, while the same-size pack is handy for restocking a drill case, workshop drawer or site box. For anyone who gets through this size regularly, having a full cobalt drill set close by is useful for repeated drilling and helps keep work moving without unnecessary interruptions. They are also easier to organise than mixed loose bits, which makes storage and quick access more straightforward between jobs.
