Twist Drill Type N — 8.4 mm, 135°, short, bright finished, HSS‑G, DIN 338 (MetavCUT)

A Twist Drill Type N designed for precise metalworking, ideal for Drilling Machines where stability and clean holes are required.

• Short Twist Drill Type N 8.4 mm diameter
• 135° point for harder materials like stainless steel
• HSS‑G ground for sharp cutting and fast drilling
• Fully ground shank for high concentricity and stability
• Complies with DIN 338 for short cylinder shanks

High cutting performance for demanding metal jobs

The HSS‑G composition and ground geometry deliver a clear benefit: faster, cleaner drilling with less operator effort. This short design reduces the exposed length and therefore the tendency to bend, so users achieve precise holes even in tough materials. For professionals working with alloyed or unalloyed Steel, Cast Steel and Hardened Plastics, the result is a higher first‑pass success rate and reduced rework time.

Stable handling and improved concentricity for machine use

Because the shank is fully ground, the bit runs truer in the chuck, which directly reduces runout and improves hole accuracy. The reduced vibration also extends tool life and lowers the risk of breakage during stationary or portable drilling operations. This is particularly valuable when drilling on a Drilling Machine under feed and coolant, where consistent concentricity matters.

Geometry designed for hard materials and precise starts

A 135° point angle shortens the initial penetration time on harder workpieces and helps to centre the bit without wandering. The Type N normal spiral profile is optimised for metalworking and provides reliable chip removal while maintaining cutting edge stability. For less experienced users: a larger point angle means easier start and less burr formation on the exit side.

Short length advantage and recommended applications

The short overall length increases rigidity, which lowers the chance of deflection and improves surface finish in the hole. This makes the bit especially suitable for precise workshops and production runs where repeatability is required. Typical applications include drilling in Steel, Cast Iron, Sintered Materials and Non‑Ferrous Metals where high accuracy and clean bores are demanded.

Target user and usage tips

Designed for machinists, toolroom personnel and serious hobbyists, this HSS‑G short twist drill suits situations where stability and hole quality are priorities. For best results, use appropriate cutting fluid and moderate feed rates; because ground bits can be more brittle than rolled alternatives, avoid excessive side loads and prefer stationary machines or rigid setups.

FAQ

What are Twist Drills used for?
Twist Drills such as the MetavCUT Twist Drill Type N are mainly applied to the machining of high‑strength materials and larger drill diameters; their form is easy to sharpen and they withstand heavy loads, making them ideal for demanding metal drilling tasks.

Which three drill types exist?
The three primary drill categories are metal drills, wood drills, and masonry/concrete drills.

Can the MetavCUT Twist Drill Type N be used in wood?
A metal Twist Drill can be used in Wood, but guidance and finish are generally inferior compared with dedicated wood bits; metal drills are easier to resharpen and show less self‑feeding, so results may be acceptable for non‑critical tasks.

At which drilling depths is a Twist Drill most commonly used?
A Twist Drill is the most frequently used tool for through drilling; it is common for diameters up to 20 mm and drilling depths up to 100 mm, especially for stable, full‑section bores in metal.
