Twist Drill — Type N short, 8.2 mm, 135° tip, 5% cobalt-alloyed, HSS‑E, DIN 338 (MetavCUT)

A Twist Drill Type N short designed for precision metal drilling with Drilling Machines, offering enhanced stability and wear resistance for demanding workshop tasks.

• Short design for higher stability
• 5% cobalt-alloyed HSS‑E for heat resistance
• 8.2 mm diameter with 135° tip for hard metals
• Fully ground shank for accurate runout
• Conforms to DIN 338 for standardised quality

Stable drilling in hard materials that reduces vibration and breakage

The short design of this drill gives a reduced overhang and therefore higher stability during machining. With an 8.2 mm diameter and a spiral length of 75 mm, the geometry minimises bending forces when used in a Hand Drill or on stationary Drilling Machines. For operations in tougher materials the compact length helps to keep the tool steady, which reduces chatter and the risk of sudden breakage while improving hole accuracy and surface finish.

Material choice and cutting geometry for longer tool life

Made from HSS‑E and alloyed with 5% cobalt, the drill maintains cutting hardness and heat resistance at elevated temperatures. The 135° tip angle is optimised for penetrating hardened and stainless steels, shortening the initial piercing time and improving centring in the workpiece. The combination of material and geometry makes the tool suitable for alloys and cast iron while preserving cutting edges when proper cooling is applied.

Precision manufacture: grinding, runout and compliance

This item is produced as a fully ground (HSS‑G) short Twist Drill rather than roll‑formed, which results in very sharp cutting lips and high concentricity. The ground flutes and accurately ground shank improve runout and produce clean bore surfaces, especially important when drilling small diameters in metal. Conformity to DIN 338 ensures the dimensions and tolerances meet recognised standards for short cylindrical shank drills.

Who benefits most: applications and working tips

Engineers, toolroom technicians and advanced hobbyists working with metal will value the performance of this short Type N drill for precise tasks and for drilling up to depths compatible with a 75 mm spiral length. Use moderate speeds, appropriate cutting fluid and a steady feed to exploit the cobalt alloy’s heat resistance. If drilling non‑ferrous materials or wood, expect less guidance than with specialised wood drills; however the tool can still be used with care for multi‑purpose tasks.

FAQ

What is the main use of the Twist Drill and where does it perform best?
The MetavCUT Twist Drill Type N short is primarily used for machining high‑strength metals and for larger hole diameters in metalworking; its short design improves stability and precision when drilling steels, castings and non‑ferrous alloys.

Which three drill types exist and how does this product fit in?
There are Metal drills, Wood drills and Masonry/Concrete drills; the MetavCUT Twist Drill belongs to the Metal drill group and is engineered for use in metalworking applications.

Why are Twist Drills sharpened at the tip?
Sharpening reduces the cross‑edge at the tip of a Twist Drill, which lowers friction and the necessary feed force; this also improves centring so the tip starts the hole more accurately in the workpiece.

Can a metal Twist Drill be used to drill wood?
A Metal drill can be used in Wood, but the guidance is generally poorer and the hole finish may not be as clean; however metal drills are easier to resharpen and tend to have a lower self‑feeding tendency compared to specialised wood bits.

For which hole depths is the Twist Drill most commonly used?
A full bore into solid material is typically made with a Twist Drill; for diameters up to about 20 mm and drilling depths to around 100 mm, the Twist Drill is the most commonly used tool.

Is HSS or HSSE better?
The common belief that HSSE steels are always superior to standard HSS is not universally correct; selection should be based on working conditions and whether the additional cost of HSSE is justified for your specific application.
