Product information

Description

Twist drill bit made of high speed steel (HSS-G) with a 4 mm diameter, manufactured to DIN 340. The right-hand cutting, two-flute cylindrical drill has a split point ground to DIN 1412 C with a 135° tip angle and diameter tolerance h8. The bit is ground from solid metal and has an oxide-coated surface to improve chip removal. The shank equals the drill diameter; colour and packaging vary by pack size (polished in packs of 1, black in packs of 5).

Advantages

The Bosch HSS-G 4 mm twist drill provides precise diameter tolerance and a 135° split-point tip for accurate centring and reduced walking. Oxide coating supports smoother chip evacuation and increases wear resistance during metal drilling. Ground from solid metal with two flutes, it delivers consistent cutting performance for a range of metalworking tasks.

Suitable for

  • Drilling in steel and non-ferrous metals
  • General metal fabrication and maintenance tasks
  • Workshop and industrial applications requiring precise 4 mm holes

How to use

Mark the drilling point and secure the workpiece. Use an appropriate drill chuck and a suitable cutting speed for the metal being drilled. Apply steady feed pressure and allow the drill to cut without excessive force. Withdraw periodically to clear chips if drilling deep holes. After use, clean the drill and store it dry to prevent corrosion.

Usage recommendations

For best results when drilling metals, use cutting fluid or lubricant, select correct spindle speed for the material thickness and hardness, and replace the bit if wear or damage to the split point is observed.
