Twist Drill — Type N, 12.7 mm, 135° Point, 5% Cobalt‑Alloyed, Short, HSS‑E, DIN 338, Fully Ground by MetavCUT

The Twist Drill Type N is a short HSS‑E drill designed for precise metalworking with a 12.7 mm diameter and a 135° point angle, suitable for use in drilling machines.

• Short design for high stability
• 12.7 mm Diameter for precise holes
• 135° point angle for hard materials
• Fully ground HSS‑E with 5% cobalt alloy

Outstanding precision and reduced deflection for metalworking

The short geometry of this Twist Drill reduces the exposed length and therefore significantly lowers the tendency to bend under load, resulting in cleaner holes and better positional accuracy. The reduced cantilever length improves lateral stiffness, which means less wobble when machining tougher materials. For workshop applications that demand repeatable hole quality, the shorter construction offers measurable advantages in stability and process control.

Material composition that improves heat resistance and wear life

Manufactured from HSS‑E with 5% cobalt, the drill combines the toughness of high‑speed steel with enhanced hot hardness for longer life under elevated temperatures. This composition is particularly advantageous when working with alloyed and unalloyed steel, cast iron, non‑ferrous metals and plastics, since it helps maintain cutting edge geometry during sustained cutting. The 135° point angle further supports drilling in harder materials by reducing initial cutting forces and improving centring.

Fully ground geometry for sharp edges and precise bores

The fully ground flute and cutting geometry (geschliffen) produce very sharp edges and high concentricity, delivering clean, burr‑reduced bores and excellent roundness. Ground drills are typically favoured for demanding metalworking where hole quality matters most; they offer superior runout characteristics compared with rolled alternatives. Note that ground HSS‑E drills perform best with appropriate clamping and coolant use to mitigate breakage risk during heavy or interrupted cuts.

Designed for professionals who require repeatability and control

This short Type N twist drill is aimed at machinists and maintenance technicians who prioritise precise hole placement and minimal deflection. It is optimised for use in stationary and portable drilling machines and performs well in tasks requiring high positional accuracy. To get the best out of the tool, use steady feeds, adequate clamping and coolant when drilling into harder alloys — this ensures consistent tool life and hole quality across batches.
