Twist Drill — Type N short, 7.6 mm, 135° point, HSS‑E, 5% cobalt‑alloyed (MetavCUT)

The Twist Drill Type N short is a precision metal drilling bit designed for drilling machines and handheld drills, optimised for hard materials and stable, accurate holemaking.

• Short design for greater stability
• 135° point for hard materials
• HSS‑E with 5% cobalt for higher toughness
• Fully ground shank for precise runout
• Conforms to DIN 338 for metal drilling

High stability and cutting performance for demanding metal work

The short design of this Twist Drill reduces overhang and significantly improves stability during drilling, which minimizes bending and runout. Combined with the HSS‑E substrate and 5% cobalt alloying, the bit shows increased resistance to heat and wear when cutting steels and other tough metals. The 135° point angle is engineered to reduce chipping when penetrating hard materials and to slow the initial centring time, leading to cleaner entry holes and less workpiece deformation.

Precision geometry and control for reliable results

A fully ground shank and CNC-ground flute geometry ensure excellent concentricity and a smooth chip evacuation pattern; this results in a consistent hole diameter and better surface finish. The tool’s spiral length of 75 mm and overall length of 117 mm are balanced for use in both drilling machines and controlled handheld applications, offering a good compromise between accessibility and rigidity. For best results, use appropriate cutting speeds, steady feed and coolant when machining stainless steels or other hard alloys.

Designed for professionals and demanding applications

This Twist Drill in the Standard Line by MetavCUT is aimed at metalworkers, maintenance engineers and toolroom technicians who require a robust, repeatable solution for drilling into alloyed and unalloyed steels, cast iron and non‑ferrous metals. The Type N normal spiral design is the proven classic for metal drilling and provides a dependable choice where straightforward, high‑quality holes are needed. The shorter flute length makes it particularly suitable for precision tasks and confined setups.

Care, handling and compatibility guidance

To prolong tool life and maintain hole quality, clamp workpieces securely, select speeds appropriate to HSS‑E drills and apply cutting fluid for heat management. The short Twist Drill performs best with reduced overhang and minimal lateral force; avoid aggressive side loads to prevent premature fracture. If machining very hard alloys, progressively reduce speed and increase cooling to maintain cutting-edge integrity. The designation DIN 338 indicates this bit conforms to recognised standards for short twist drills with cylindrical shank.

FAQ

What materials is the MetavCUT Twist Drill Type N suitable for?
The MetavCUT Twist Drill Type N with HSS‑E and 5% cobalt is primarily intended for drilling alloyed and unalloyed steel, cast iron and non‑ferrous metals; it performs well where heat resistance and edge retention are required.

Can this Twist Drill be used in handheld drills?
The short construction of the MetavCUT Twist Drill Type N improves stability and makes it suitable for careful use in handheld drills, though best results are achieved in a drilling machine or with firm workpiece clamping and controlled feed rates.

For what is a Twist Drill used?
A Twist Drill is mainly applied when machining high‑strength materials and larger drill diameters. Its geometry is easy to re‑grind and it withstands high loads, making it suitable for robust metalworking tasks.

Which three drill types exist?
The three main drill types are metal drills, wood drills and stone/concrete drills.

Why are Twist Drills pointed?
Pointing reduces the cross‑cutting edge at the tip of the Twist Drill. By pointing, friction forces are significantly lowered so that less feed force is required, while the tip centres better in the workpiece.

Can you drill wood with a Twist Drill?
A metal drill can also be used in wood, but guidance and surface finish are inferior; however, such drills are easier to re‑grind and typically exhibit lower self‑feeding tendencies.

For which drilling depths is the Twist Drill most used?
A through‑hole in solid material is commonly made with a Twist Drill. For diameters up to 20 mm and depths up to 100 mm, the Twist Drill is the most frequently used tool.
