Twist Drill — Type N, 8.3 mm, 135° tip, short, 5% cobalt-alloyed, HSS‑E, DIN 338, fully ground

The Twist Drill Type N is a short HSS‑E metalworking drill designed for precision drilling in hard materials with Drilling Machines.

• Short design for increased rigidity and precision
• Fully ground flutes for sharp edges and clean holes
• 8.3 mm Diameter with 135° tip for hard metals
• Conforms to DIN 338 for short cylinder‑shank drills
• 5% cobalt‑alloyed for enhanced heat resistance

High‑precision drilling thanks to a short, rigid design

The short execution of this Twist Drill reduces overhang and significantly improves stability during machining, which leads to more precise hole geometry and lower runout. For operations in steel and other hard alloys the reduced cantilever length minimises bending forces and vibration, increasing tool life under comparable conditions. This makes the drill particularly suitable where tight tolerances and concentricity are required.

Sharp, ground geometry for clean metal holes

A fully ground flute geometry produces very sharp cutting edges and high concentricity. The fully ground manufacturing method delivers precise cutting geometry that results in cleaner hole surfaces and consistent diameters when drilling metals. While rolled drills can be tougher, the ground version provides superior finish and dimensional accuracy, especially in demanding stationary or machine‑guided applications.

Material choice and tip geometry tailored for hard materials

Manufactured from HSS‑E with a 5% cobalt alloy, the drill combines toughness with elevated hot hardness for higher cutting temperatures. The 135° tip angle reduces initial cutting forces and is optimised for hard steels and stainless materials, shortening dwell during entry. For users unfamiliar with tip angles: a larger tip angle flattens the point and spreads cutting load, which helps when penetrating high‑strength materials.

Suitable applications and typical working conditions

This Type N Twist Drill is intended primarily as a metal drill for use on Drilling Machines and similar equipment, handling alloyed and unalloyed steels, cast iron, non‑ferrous metals and many plastics. Due to its ground geometry, the tool is best used with appropriate coolant and controlled feed to avoid chipping; it excels in precision workshop and production environments where clean, repeatable holes are required.

Who benefits from this drill

Metalworkers, toolroom technicians and production engineers who require accurate, repeatable holes in harder materials will value the combination of a short gaging length, HSS‑E material and a 135° tip. The design is aimed at users seeking improved stability and hole quality rather than extreme flexibility for long deep drilling; it is therefore particularly well‑suited to machine‑based drilling tasks.

FAQ

What is the best use for the Twist Drill (MetavCUT, Type N)?
The Twist Drill from MetavCUT, Type N, is primarily used for metalworking tasks and excels when drilling alloyed and unalloyed steels, cast iron and many non‑ferrous metals. Its short design and HSS‑E composition make it especially suitable for precise, machine‑guided holes in harder materials.

Which three drill types exist and how does this Twist Drill relate to them?
Common drill families are metal drills, wood drills and masonry/concrete drills. The MetavCUT Twist Drill (Type N) belongs to the metal‑drill category and is optimised for machining metals rather than timber or stone.

For what is a Twist Drill mainly used?
A Twist Drill is mainly applied in the machining of high‑strength materials and larger diameters; its geometry is relatively easy to resharpen and it withstands substantial loads. The shape and heat treatment permit reliable use in demanding metal drilling operations.

Why are Twist Drills point‑sharpened?
Point sharpening reduces the cross‑cut at the tip of the Twist Drill, lowering friction and therefore required feed force; this also improves centring and reduces walking, enabling easier, more controlled penetration into the workpiece.
