Description
The Alpha Onsite Plus Step Drill Spiral Flute range has been designed to provide tradespeople with faster drilling speeds, smoother cutting performance and improved chip removal when drilling a variety of materials.
Manufactured with premium AlCrN (Aluminium Chromium Nitride) coating, these step drills offer excellent wear resistance and superior heat resistance for extended tool life. The spiral flute geometry efficiently removes swarf during drilling, helping to reduce clogging and improve cutting performance.
Unlike conventional step drills, the Onsite Plus range offers a 10mm cutting depth, making it suitable for thicker materials commonly encountered in fabrication, electrical, plumbing and general construction applications.
Suitable for use in power drills, these professional-grade step drills produce clean, burr-free holes while significantly reducing the need for multiple drill bits.
