RUKO SPB-DIN345 21,0 mm HSS-E-Co5 morseconus-spiraalboor

Precision-ground 21.0 mm Morse taper shank drill bit in HSS-E-Co5 cobalt high-speed steel, engineered for high-alloy steels, stainless steels, heat-resistant steels, titanium alloys, and cast iron. The split point (Form C) with 130° point angle ensures accurate self-centering and reduces thrust, while the bright finish and h8 tolerance deliver consistent performance.

Overview

This RUKO SPB-DIN345 drill bit conforms to DIN 345 and features a Morse taper shank size MK2 (MT2) for secure tool holding in drilling machines. The bit is ground from solid HSS-E-Co5, which contains 5% cobalt for enhanced heat resistance and wear resistance. With a total length of 235 mm and a flute length of 145 mm, it is suitable for deep-hole drilling operations. The right-hand cutting direction and standard spiral flute design ensure efficient chip evacuation.

What stands out

• HSS-E-Co5 cobalt steel withstands high temperatures, ideal for tough materials.
• Split point (Form C) eliminates walking and provides precise hole location.
• Morse taper shank MK2 (MT2) allows quick tool changes and secure fit.
• DIN 345 compliance guarantees dimensional accuracy and interchangeability.
• Bright finish reduces friction and improves chip flow.
