Twist Drill Set 1-13mm 25pc HSS Cobalt 5% Split Point

A 25-piece twist drill set covering sizes from 1mm to 13mm for general drilling work in the garage, workshop or on site. Made from HSS with 5% cobalt and fitted with 135° split points, these bits are suited to buyers who want a broad size range ready for regular jobs.

Used for drilling a wide spread of hole sizes during vehicle maintenance, fabrication, fitting work, workshop tasks and DIY repairs, this cobalt drill set gives you one bit in each common step size from 1mm up to 13mm. That makes it useful when working across thin metal, brackets, panels and general repair jobs where accurate sizing matters and you do not want to keep searching for individual replacement bits. For trade use or home maintenance, the range helps cover everything from smaller pilot holes through to larger fixing and clearance holes.

The practical benefit here is the full 25-piece size progression, giving you half millimetre increments through the range for easier matching to fasteners, fixings and planned hole sizes. The 135° split point tip helps the bit start more cleanly and reduces wandering compared with a standard point, which is handy when working on smooth surfaces. HSS cobalt 5% construction makes the set a sensible choice for repeated workshop use, while the broad size coverage helps avoid gaps between common drill sizes when everyday jobs come up.
