Milwaukee Punte per metallo HSS-G 12,5 mm (confezione da 5)

Professional machinists and metal fabricators reach for this Milwaukee HSS-G twist drill bit when they need clean, accurate holes in steel plate, angle iron, or cast components. The 12.5 mm diameter is a common size for clearance holes for M12 bolts, and the split point starts on contact without wandering, even on curved or uneven surfaces.

Why choose it

The HSS-G construction with a ground finish delivers a sharp, precise cutting edge that resists wear and heat build-up. The 135° split point reduces thrust pressure and prevents the bit from skating across the workpiece, so you can start holes accurately without a centre punch. Suitable for a wide range of metals including alloyed and non-alloyed steel, cast iron, non-ferrous metals, and even plastics.

Ideal use cases

• Drilling clearance holes for M12 bolts in structural steel
• Creating precise holes in aluminium and copper sheet
• Maintenance and repair work on machinery and equipment
• Fabrication of metal brackets, frames, and supports
• General workshop drilling in mild steel and cast iron

Good to know

This pack contains five identical 12.5 mm drill bits, so you always have a sharp spare on hand. The cylindrical shank fits standard three-jaw chucks up to 13 mm. For best results, use cutting fluid on steel and run at the recommended speed for the material. Store the bits in a dry place to prevent corrosion.
