RUKO SPB-DIN345-19.0mm-HSS Morse Taper Shank Twist Drill Bit

Drilling large-diameter holes in tough materials like steel and stainless steel demands a drill bit that resists heat, stays sharp, and centers accurately. The RUKO SPB-DIN345-19.0mm-HSS twist drill bit with Morse taper shank is built for exactly that—precision drilling in demanding workshop and industrial tasks.

Who is it for

Machinists, metalworkers, and maintenance professionals who need reliable large-diameter drilling in steel, stainless steel, cast iron, non-ferrous metals, and plastics. Ideal for use in pillar drills and lathes with a Morse taper socket.

Main features

• 19.0 mm diameter twist drill bit with Morse taper shank (MK2) for secure tool holding and high torque transfer.
• Made from HSS-E high-speed steel with 5% cobalt for superior heat resistance and wear resistance.
• Ground from solid with a cross-ground point and 130° point angle for accurate centering and reduced thrust.
• Bright surface finish and h8 tolerance for consistent hole quality.
• Conforms to DIN 345 standard for Morse taper shank twist drills.
• Right-hand cutting direction, suitable for materials up to 1100 N/mm² tensile strength.
