RUKO SPB-DIN345-HSSCo-Ø20,0 mm kierreporanterä morsekiilakartiovarrellа

Drilling tough and abrasive materials demands a drill bit that stays sharp and precise under stress. The RUKO SPB-DIN345-HSSCo-Ø20.0mm twist drill bit solves this problem by combining a cobalt-alloyed high-speed steel body with a Morse taper shank, delivering reliable performance in steel, cast iron, stainless steel, and acid-resistant steel.

Who is it for

This drill bit is built for machinists, metalworkers, and maintenance professionals who need a durable, general-purpose tool for demanding drilling tasks. Its 20.0 mm cutting diameter and MT2 shank make it suitable for use in stationary drilling machines and lathes with a matching Morse taper socket.

Main features

• Precision-ground from solid HSS-Co for high heat resistance and long tool life.
• Morse taper shank (MT2) ensures secure, centered mounting and efficient power transmission.
• Spiral flute design with a 118° point angle for excellent chip removal and accurate hole starting.
• Bright surface finish reduces friction and improves corrosion resistance.
• Conforms to DIN 345, guaranteeing consistent geometry and interchangeability.
