Set of 19 twist drills with cylindrical shanks, made from HSS, AISI M2, entirely ground, with smaller drill for high-precision centring and quicker drilling

ø 1÷10 x 0,5 mm
HIGHER DRILLING SPEED
R ≤ 900 N/mm²
HV ~ 820÷850

Higher cutting speed:
Peculiar subland drill (available from Ø 5 mm) makes an initial small hole, and next cutter drills actual hole more quickly.
Improved stability:
Smaller drill allows high-precision initial centring and provides improved drilling stability.
Extended durability:
Superior-quality HSS, AISI M2, results in a more durable drill, suitable for low-alloy and high-alloy steel, steel, stainless steel, iron, aluminium and other metals.
Perfect hold:
Shank with 3 smooth surfaces (from Ø 5 mm) ensures a perfect hold for spindle jaws, thereby preventing slipping, and optimal force transmission.
