Cobalt Drill Bit Set 3mm 10pc HSS 5% Co Twist Drills for Metal

A 10-piece set of 3mm cobalt HSS twist drill bits for keeping replacement bits close to hand when regular drilling jobs come up. Useful as a spare set for the toolbox, these bits are suited to tougher day-to-day work where durability matters more than using basic general-purpose bits.

Used across workshops, garages, site work and home maintenance, this set suits anyone who regularly drills small, clean holes and wants matching 3mm cobalt drill bits ready to go. Handy for repair work, fitting tasks and general DIY jobs, it helps when worn bits need replacing or when you want to top up your drill bit selection for repeated use.

The 3mm size makes these bits a practical choice for common drilling tasks, while the HSS construction with 5% cobalt is intended for more demanding use than a standard bit. Supplied as a 10-piece pack, there are enough bits on hand for ongoing jobs, which is useful when keeping consumables organised in a busy tool box or workshop. For regular drilling work, having matching spares ready can also help avoid unnecessary delays when a bit becomes blunt or damaged.
