Broca helicoidal de cone Morse RUKO DIN 345 HSS 27,5 mm MT3

Morse taper shank twist drill with a 27.5 mm diameter, made from high-speed steel (HSS) and manufactured to DIN 345 standards. The MT3 taper shank ensures secure clamping and efficient power transmission in stationary drilling machines, making it ideal for large-diameter holes in tough materials.

Advantages

Ground from solid HSS for high hardness (62-64 HRC) and wear resistance. Bright, uncoated surface reduces chip adhesion and allows easy resharpening. Right-hand cutting with standard spiral flutes ensures reliable chip evacuation and stable drilling performance.

Suitable for

• Steel
• Cast iron
• Non-ferrous metals
• Plastics
