Twist Drill — Type N short HSS‑E, 8.4 mm, 135°, 5% cobalt‑alloyed (DIN 338)

The Twist Drill Type N short is a precision metal‑working drill for drilling machines, designed for stable, accurate holes in hard materials such as steel.

• Short execution for higher stability and precision
• 8.4 mm Diameter for common metalworking tasks
• 135° Point Angle for harder materials and stainless steel
• HSS‑E with 5% cobalt‑alloyed for improved heat resistance
• Fully ground shank and DIN 338 conformity for accurate bores

Reliable performance through material and geometry

The short design delivers significantly improved stability during machining by reducing overhang, which results in more concentric holes and less vibration. Manufactured from HSS‑E with 5% cobalt‑alloyed composition, this drill maintains cutting performance at higher temperatures and under heavy loads, making it suitable for alloyed and unalloyed steel as well as cast iron and non‑ferrous metals. The 135° point angle reduces walking on hard surfaces and shortens the plunge time, helping achieve clean starts even on tough materials.

Ideal use cases and users who benefit most

Engineered for metalworking professionals and workshops, the short Type N Twist Drill excels in precision tasks on drilling machines and stationaries; it is recommended where rigidity and exact hole quality matter. Its properties make it particularly useful for workshop machinists, maintenance technicians and professionals who require reproducible bores in metal components. The reduced breakage risk for diameters below 6 mm—carried over in the short design philosophy—translates into dependable performance across frequent production environments.

Design details that improve handling and results

The fully ground flute geometry (HSS‑G style) produces sharp cutting edges and high runout accuracy, which contributes to clean, burr‑reduced holes and easier re‑sharpening when needed. Conforming to DIN 338, this short Twist Drill follows standardised dimensions and tolerances for short cylindrical shank drills, ensuring compatibility with standard tooling and chucks. With a spiral length of 75 mm and an overall length of 117 mm, the geometry balances chip evacuation and rigidity for controlled drilling in metal.

FAQ

For what is a Twist Drill used?
The MetavCUT Twist Drill Type N is primarily applied when machining high‑strength materials and larger drill diameters; its short design and HSS‑E composition make it easy to re‑grind and capable of withstanding higher mechanical stress.

Which three drill types exist?
Common categories are metal drills, wood drills and stone/concrete drills; the MetavCUT Twist Drill Type N belongs to the metal drill group, optimised for steel and similar materials.

Why are Twist Drills tip‑sharpened?
The tip sharpening reduces the cross‑cut at the drill point. For the MetavCUT Twist Drill Type N this lowers friction forces, reduces required feed and improves centring of the tip in the workpiece.

Can a Twist Drill be used to drill wood?
A MetavCUT Twist Drill Type N can be used in wood, but guidance and finish are inferior compared with dedicated wood drills; metal drills are easier to re‑sharpen and have less self‑feed, resulting in a rougher hole.

At what drilling depths is the Twist Drill most used?
For through‑hole operations, the Twist Drill is typically used up to diameters around 20 mm and drilling depths up to about 100 mm; the MetavCUT Twist Drill Type N is well suited for solid drilling in these common metalworking ranges.

What is better, HSS or HSSE?
The general assumption that HSSE is universally superior to HSS is not correct; when choosing, evaluate whether the working conditions justify the higher cost. MetavCUT offers HSS‑E options that balance toughness and heat resistance for many metalworking tasks.
