Twist Drill (Type N) — 8.7 mm, 135°, Short, 5% Cobalt‑Alloyed, HSS‑E, DIN 338

The Twist Drill (Type N) is a short HSS‑E metal drill designed for precise drilling in hard and alloyed steels using a Drilling Machine.

• Twist Drill Type N by MetavCUT
• 8.7 mm Diameter for precise metal holes
• 135° Tip for harder materials
• Short design improves stability and accuracy
• HSS‑E with 5% Cobalt for increased heat resistance

Precision and Durability for Tough Metals

Designed as a short Type N bit, this HSS‑E Twist Drill delivers high stability and reduced deflection thanks to its shorter overhang. The 5% cobalt alloy increases red‑hardness and thermal resistance, so heat buildup during high‑speed metal drilling is better tolerated, extending tool life. For users who require repeatable, clean holes in Alloyed Steel and Stainless Steel, the shorter geometry directly translates into improved hole quality and fewer rejects.

Optimised Geometry for Clean, Accurate Holes

With a 135° tip angle and a fully ground flute geometry, the tool enters harder materials with less walking and lower axial force. The grinding process creates sharp cutting edges and excellent concentricity, resulting in precise bores and smooth chip evacuation. For customers unfamiliar with cutting geometry: the larger tip angle reduces penetration aggressiveness and is recommended for harder workpieces such as stainless steels.

Suited Use Cases and Who Benefits

This short, Type N HSS‑E drill is particularly appropriate for machinists and professionals working on metal fabrication, maintenance, and toolmaking. The stable design makes it ideal for drilling on bench or column Drilling Machines where rigidity matters most. If occasional mobile hand‑drilling is needed, the bit still performs, but best results are achieved with a steady, well‑clamped setup.

Standards, Manufacturing and Practical Advice

Manufactured to DIN 338 and available in a fully ground shaft execution, the bit conforms to recognised short twist‑drill specifications for industrial use. Ground (HSS‑G) drills offer superior roundness and cutting precision compared to rolled counterparts, though they can be less tolerant of shock loads. For prolonged runs, use appropriate cutting fluid and moderate feed rates to maximise tool life and hole quality.
