Twist Drill (Typ N) — short HSS‑E Metal Drill, 4.4 mm, 135° tip, 5% cobalt‑alloyed

The Twist Drill (Typ N) is a short HSS‑E metal drill designed for precise machining with a 135° point angle and a fully ground shank for secure chucking.

• Short design for higher stability
• 135° tip for hard and alloyed steels
• 5% cobalt‑alloyed HSS‑E for increased red‑hardness
• Fully ground flutes for accurate, clean holes
• Conforms to DIN 338 for short twist drills

Precision and Stability for Demanding Metalwork

A short HSS‑E drill of this design delivers notably greater stability during drilling because the reduced overhang minimises bending and vibration. The combination of a 4.4 mm diameter with a 47 mm flute length and overall length of 80 mm results in a compact tool that keeps the cutting geometry close to the chuck, improving concentricity and repeatable hole quality when used in a compatible Drilling Machine or stationary set‑up. This construction is ideal for work that requires tight tolerances and reliable hole positioning.

Optimised for Hard Materials and Clean Holes

Thanks to the 135° point angle and the 5% cobalt‑alloyed HSS‑E substrate, the drill penetrates harder and alloyed steels more effectively than standard HSS tools. The fully ground flute geometry produces very sharp cutting edges and high roundness, which leads to cleaner holes with less burring. Users should note that the grinded version offers excellent precision but can be more brittle than roll‑formed variants; appropriate coolant and stable clamping are recommended to extend tool life during high‑performance drilling.

Designed to Meet DIN 338 Requirements and Workshop Needs

Manufactured to the DIN 338 standard for short twist drills with a cylindrical shank, this tool follows established size and tolerance criteria that support interchangeability and predictable performance. The Type N spiral geometry represents the classic metal‑drill profile, suitable for materials such as alloyed and unalloyed steel, cast iron, non‑ferrous metals and certain plastics. The short format is particularly suited to precision workshop tasks where reduced run‑out and minimal deflection are priorities.

Who benefits from this short HSS‑E drill?

Engineers, toolroom technicians and metalworkers who require accurate, repeatable holes in tougher materials will find this drill especially useful. Its compact design and fully ground shank make it a strong choice for setups where rigidity matters—such as jig bores, component finishing and jobs on vertical or radial drilling machines. For less rigid hand‑held applications, ensure a secure chuck grip and moderate feeds to avoid undue stress on the cutting edge.

FAQ

What is the Twist Drill (MetavCUT, Type N) mainly used for?
The MetavCUT Twist Drill (Type N) is primarily applied to the machining of high‑strength materials and larger drill diameters; its form allows straightforward re‑grinding and it endures higher mechanical loads, making it suitable for demanding metalworking tasks.

Which three drill types are there?
There are three common drill categories: metal drills, wood drills and stone/concrete drills.

Why is a twist drill pointed (ausgespitzt)?
The pointing reduces the cross‑cut at the drill tip, which significantly lowers friction and thus the required feed forces; at the same time the sharper point improves centring of the drill in the workpiece.
