Broca helicoidal HSS RUKO DIN 345 10,0 mm haste de cone Morse MT1

Drilling precise 10 mm holes in tough metals demands a bit that stays sharp and centered. The RUKO SPB-DIN345-10,0mm-HSS twist drill bit is ground from solid high-speed steel to DIN 345, delivering reliable performance in steel, cast iron, and non-ferrous metals. Its Morse taper shank (MT1) seats securely in machine spindles, reducing slippage under load.

Who is it for

Machinists, metalworkers, and maintenance technicians who need a durable, accurate twist drill for general-purpose drilling on stationary machines. This bit suits workshops, production lines, and repair jobs where a 10 mm hole is required.

Tips

Use cutting fluid when drilling steel to extend tool life and improve hole quality. Ensure the Morse taper and spindle socket are clean before mounting to prevent runout. For deep holes, withdraw the bit periodically to clear chips.
