Twist Drill (Type N) — 6.2 mm, 135° tip, short HSS‑E, 5% cobalt‑alloyed, DIN 338 — MetavCUT

A Twist Drill (Type N) designed for precise metal drilling, combining a 6.2 mm diameter and a 135° tip angle in a short, stable execution suitable for demanding machining tasks.

• Type N Twist Drill, 6.2 mm diameter
• 135° tip angle for hard materials
• Short execution for higher stability
• HSS‑E with 5% cobalt for improved toughness
• Fully ground shank, DIN 338 compliant

Exceptional stability and precision for metalworking

Short-form drills deliver measurable advantages when precision matters. The short design of this MetavCUT Twist Drill reduces the unsupported overhang, which increases stability and lowers the tendency to wander or bend under load. Combined with the 135° tip angle, the geometry shortens pilot time and improves centring in harder materials. For production environments that require repeatable hole quality, the shorter spiral length also reduces vibration and contributes to more consistent hole diameter and surface finish.

Material composition for longer life under stress

Constructed from HSS‑E and alloyed with 5% cobalt, this short Twist Drill offers higher hot hardness and greater wear resistance than standard HSS. The cobalt content increases toughness at elevated temperatures, making the tool more suitable for drilling alloyed and unalloyed steel, cast iron, non‑ferrous metals and certain plastics. The fully ground flute geometry provides very sharp cutting edges and high running accuracy; however, grinding can increase brittleness, so coolant use and stable clamping are recommended to maximise tool life.

Designed for drilling machines and demanding applications

Classified to DIN 338, this Type N drill is the classical metal drill geometry optimised for machining of metallic workpieces on drilling machines. The shorter overall length and fully ground spiral make it particularly suited to stationary machines and operations that require high precision rather than freehand drilling. Typical applications include workshop fabrication, maintenance, toolmaking and any task where controlled drilling into Steel and similar materials is required. Note that Type N is not optimised for very soft materials where specialised geometries perform better.

Practical advice for safe and efficient use

When using the MetavCUT Twist Drill, ensure secure clamping and appropriate coolant or cutting fluid to dissipate heat and extend tool life. Start with a light feed to establish the hole, especially in harder materials, and avoid excessive spindle speeds that can overheat the tip. The 135° point reduces entry forces and improves centring for harder alloys, while the short execution minimises deflection—both contributing to cleaner, more accurate holes. For portable handheld drilling machines, consider the shorter projection to reduce user fatigue and increase control.

FAQ

What is the MetavCUT Twist Drill (Type N) mainly used for?
The MetavCUT Twist Drill (Type N) is primarily applied for machining high‑strength materials and larger bore diameters. Its short form suits precise work and makes the drill easier to re‑grind while maintaining resistance to higher loads in metalworking operations.

Which three drill types exist?
There are three common drill types: metal drills, wood drills and stone/concrete drills. The MetavCUT Twist Drill (Type N) belongs to the metal drill category, optimised for use in metalworking environments.

Why are Twist Drills pointed?
The point geometry reduces the cross‑cut at the tip of a Twist Drill, which lowers friction and thus requires smaller feed forces. By sharpening the tip, the drill centres more reliably in the workpiece and cuts with less resistance, improving entry behaviour and hole quality.

Can you use a Twist Drill to drill wood?
A metal drill such as the MetavCUT Twist Drill (Type N) can be used in wood, but guidance and centring are generally poorer and the finish may be less clean compared with purpose‑made wood bits. Metal drills are easier to re‑grind and show less self‑feed, which can be an advantage in some hobby or repair scenarios.

For which drilling depths is the Twist Drill most commonly used?
A through hole in a solid piece is typically executed with a Twist Drill. For diameters up to 20 mm and drilling depths up to 100 mm, the Twist Drill is the most frequently used tool. The MetavCUT Twist Drill (Type N) is therefore appropriate for many standard metal drilling tasks.

What is better, HSS or HSSE?
The common assumption that HSSE steels are always superior to standard HSS is not universally correct. Choose between HSS and HSSE based on actual working conditions and whether the higher purchase cost of HSSE is justified by the specific performance benefits required.
