Introducing the Twist Drill (Type N) — 5 mm diameter · 135° point · short execution · 5% cobalt-alloyed · HSS‑E · DIN 338 · MetavCUT

The Twist Drill (Type N) is a short 5 mm metal drilling bit designed for precise work on drilling machines and hardened materials.

• Short design increases rigidity for precise holes
• 135° point angle for easier entry in hard metals
• 5% cobalt-alloyed HSS‑E for improved heat resistance
• Fully ground shank for high roundness and accuracy
• Conforms to DIN 338 for standardized reliability

Greater precision and reduced deflection for metalworking

A short design delivers a tangible advantage in stability: the reduced overhang lowers bending and vibration, so drilling remains accurate even under higher cutting forces. This construction makes the bit especially suited to precision tasks in metalworking where hole roundness and positional accuracy matter. The result is fewer rejects and less rework when producing mating parts or tight-tolerance holes.

Material composition that withstands heat and stress

Manufactured from HSS‑E with 5% cobalt, the bit offers enhanced hot-hardness compared to standard HSS; this allows higher cutting temperatures without rapid softening. The fully ground geometry creates very sharp cutting edges and excellent concentricity, which improves hole finish. For users unfamiliar with these terms: HSS‑E is a high-speed steel alloyed with cobalt to maintain hardness at elevated temperatures, and "fully ground" means the flute geometry is generated by grinding for superior precision.

Clear guidance on application and machine compatibility

Designed for use in a Drilling Machine and similar stationary or powered setups, this bit performs well on alloyed and unalloyed steel, cast iron, non‑ferrous metals and many plastics. The flute (spiral) length of 52 mm and overall length of 86 mm balance chip evacuation and rigidity for typical shop tasks. As a Type N normal-spiral configuration, it is optimized for metal work rather than soft wood; for clean woodworking holes, a dedicated wood bit is preferable.

Practical handling tips to extend tool life

To reduce wear and avoid breakage, employ proper coolant and moderate feed for holes under 6 mm diameter—this short version already lowers the fracture risk but benefits from lubrication. The 135° point angle reduces initial cutting forces and helps the bit enter harder materials with less skidding; when re-grinding becomes necessary, the fully ground geometry is straightforward to restore on suitable equipment. These simple measures extend service life and maintain hole quality.
