HSS-G drill for metal DIN 338 type N series 109 Perfect
- Fully ground HSS-G high-speed steel for maximum dimensional precision.
- Manufactured to DIN 338 type N.
- 118° point with Split Point from Ø 2 mm for fast centring and lower feed pressure.
- h8 diameter tolerance for a precise fit in the chuck.
- Drilling depth up to 5ר.
The HSS-G DIN 338 type N twist drill is a versatile solution with good performance and durability for routine work and general professional use, made of fully ground high-speed steel to guarantee dimensional precision and stability during machining.
The full grinding improves concentricity and drilling accuracy. It has a 118° point angle and Split Point grinding from Ø 2 mm, reducing axial pressure and optimising centring. The 30° helix allows effective chip evacuation and stable behaviour during drilling. It has a bright finish and h8 tolerance to DIN 338.
