Bosch PRO Metal broca helicoidal HSS-G 1,5 x 18 x 40 mm

Precision-ground twist drill bit for clean, accurate holes in metal. The Bosch PRO Metal HSS-G 1.5 mm bit combines high-speed steel construction with a self-centring split point, delivering reliable performance in alloyed and non-alloyed steel, cast iron, non-ferrous metals, and plastics.

Advantages

Ground from solid HSS-G for excellent durability and concentricity. The 135° split point starts fast, reduces walking, and requires less feed pressure. Bright finish prevents chip build-up and allows easy resharpening. Cylindrical shank fits standard keyed or keyless chucks.

Suitable for

• Alloyed and non-alloyed steel
• Cast iron
• Non-ferrous metals (aluminium, copper, brass)
• Plastics
• Handheld drills and drill presses
