Twist Drill — Type N short, 6.8 mm, 135° tip, bright finished, HSS‑G, DIN 338 (MetavCUT)

The Twist Drill Type N short is a precision metalworking bit designed for stable, accurate drilling in Drilling Machines and similar equipment.

• Short design for higher stability
• 6.8 mm diameter for precise holes
• 135° tip for hard material starts
• Fully ground shank for accurate runout
• HSS‑G ground steel for clean metal drilling

Greater precision through reduced overhang and rigidity

A shorter flute length reduces the exposed part of the tool, which directly improves stability and minimises deflection during cutting. This design makes the short Twist Drill particularly suitable for demanding, precision tasks in metalworking where straight, accurate holes are required. For users who rely on repeatable results, the shorter projection reduces vibration and contributes to consistent hole geometry even in tougher materials.

Ground HSS‑G geometry for cleaner holes and faster cutting

The HSS‑G (ground) manufacturing method means the spirals and cutting edges are produced by CNC grinding rather than roll forming. This yields very sharp cutting edges and high runout accuracy, producing cleaner bores with less burr. According to manufacturer data, the ground HSS geometry can enable up to 40% faster drilling and may require approximately 50% less feed force compared with conventional HSS bits, which is beneficial when working with alloys or hardened steels. Note that ground tools are more brittle than rolled alternatives, so stationary machines and adequate cooling are recommended.

Optimised for metal — clear guidance on suitable materials

This Type N short Twist Drill is designed for metal applications and performs well in a range of workpieces such as alloyed and unalloyed steel, cast steel, cast iron, sintered iron, malleable iron, non‑ferrous metals and hard plastics. The 135° tip angle improves penetration and reduces chipping when starting holes in harder materials like stainless steel. For workshop professionals and maintenance technicians, this bit offers a reliable balance between cutting aggressiveness and centring behaviour.

Conformity and machine compatibility for safe workshop use

Manufactured to DIN 338, the drill corresponds to the standard for short twist drills with cylindrical shanks. The fully ground shank ensures consistent seating in the chuck and reduced radial runout, which is important when using both portable Drilling Machines and stationary machine tools. Technical dimensions: flute length and overall length are specified to support correct selection for the clamping length available in your machine, reducing the risk of excessive overhang.

FAQ

What is the best use for the Twist Drill Type N short from MetavCUT?
The MetavCUT Twist Drill Type N short is primarily used for precision drilling in metals; its short design and HSS‑G geometry make it ideal for demanding tasks in alloyed and unalloyed steel, cast materials and hard plastics where stability and clean holes are required.

Can the MetavCUT Twist Drill be used in hand drills or only in machines?
The MetavCUT short Twist Drill Type N is suitable for use in Drilling Machines and can be used in robust hand drills if the chuck and clamping conditions ensure low runout; however, for maximum lifetime and safety, stationary machines with proper cooling are recommended.

For what is a Twist Drill used?
It is mainly applied to the machining of high‑strength materials and larger drill diameters. The form is easy to grind and withstands higher loads.

Which three drill types exist?
There are Metal drills, Wood drills, and Stone/Concrete drills.

Why are Twist Drills sharpened at the tip?
The sharpening reduces the cross‑cut at the tip of the Twist Drill. By sharpening, friction forces are significantly lowered so that lower feed forces are required; at the same time the drill tip is better centred in the workpiece.

Can a Twist Drill be used to drill wood?
Metal drills can indeed be used in wood. They offer poorer guidance and less clean results than dedicated wood bits, but they are easier to re‑grind and exhibit less self‑feed.

For which drilling depths is the Twist Drill most used?
A full‑bore hole is usually executed with a Twist Drill. For diameters up to 20 mm and drilling depths up to 100 mm, the Twist Drill is the most commonly used tool.

Is HSS or HSSE better?
The common belief that HSSE steels are inherently superior to standard HSS is not universally correct; you should weigh up whether the working conditions justify the higher purchase price before choosing HSSE over HSS.
