• HSS-M2 step drill bit made of high speed steel, coated with titanium nitride.
• 3 faced shank to avoid chuck sliding.
• El Recubrimiento de nitruro de titanio alarga considerablemente la vida útil de la broca, y permite perforar aceros de mayor dureza.
• The titanium nitride significantly increases the bit lifespan allowing harder steel drilling.
• Sharpened tip to improve drilling quality on softer materials, without previous marking needed.
• Spiral grooving for an improved debris removal reducing vibrations and increasing drilling speed.
• We advise doing a previous smaller drilling before using this bit on harder materials.
Suited for thin metal sheet drilling, non ferrous materials, steels, copper, brass, aluminum, PVC, glassfibre & wood. 3 faced Cylindrical shaft.
Use with a hand drill, bench drills with a 10 mm or more
