Twist Drill (Spiralbohrer) — Ø 8.6 mm · 135° tip · Type N · Bright finished · Short · DIN 338 · HSS‑G · MetavCUT

The Twist Drill is a short HSS‑G metal drill designed for precise drilling in hard materials on Drilling Machines.

• Short design for higher stability and precision
• Conforms to DIN 338 for short twist drills
• 135° tip optimised for hard materials
• Fully ground shank for high concentricity
• Up to 40% faster drilling with reduced feed force

Deliver faster, cleaner holes with a short HSS‑G design

The short Twist Drill construction reduces overhang and vibration, which directly improves stability and hole quality. Thanks to the HSS‑G (ground High Speed Steel) geometry, cutting edges are sharper and concentricity is higher than rolled alternatives, leading to more consistent hole diameters and less rework. The reduced tendency to wander makes this drill particularly effective when accuracy matters, for example when preparing holes for threaded fastenings in metal components.

Precision at the tip: why 135° helps with hard materials

A 135° tip angle increases the contact area at the point and reduces the initial penetration aggressiveness compared with steeper tips, which helps when drilling stainless steel, cast and alloyed steels or hard plastics. The Type N normal spiral is the classic metalworking geometry and provides reliable chip evacuation and centre guidance. In practice, this means fewer retries, reduced burr formation and a cleaner finish on the workpiece.

Suitable machines and material range for consistent results

This short Type N Twist Drill is intended for metalworking on rotating machines and is suitable for both stationary Drilling Machines and compatible portable setups when rigidity is ensured. It is recommended for alloyed and unalloyed steel, cast steel, cast iron, sintered iron, non‑ferrous metals and hard plastics. The fully ground shank ensures tight clamping and low runout, improving tool life and repeatability in production environments.

Handling advice to maximise performance and tool life

Ground HSS drills can be more brittle than rolled types; therefore, apply moderate feed and appropriate cutting fluid when machining metals to avoid premature breakage. Correct speed and steady feed are essential: slower speeds and continuous coolant are advised for harder alloys. For precise positioning, use a pilot or centre punch before drilling. If uncertain about speeds, feeds or machine setup, expert advice is available from METAV Werkzeuge to match operating conditions to material and hole requirements.

FAQ

What is the MetavCUT Twist Drill used for?
The MetavCUT Twist Drill (Type N) is primarily used for drilling in hard and high‑strength materials; it is especially suited to metalworking tasks such as holes in alloyed and unalloyed steel, cast steel, cast iron, sintered iron, non‑ferrous metals and hard plastics, where precision and stability are required.

Which three drill types exist?
The three main drill categories are Metal drill, Wood drill and Stone/Concrete drill; the MetavCUT Twist Drill belongs to the metal drill family and is optimised for machining metals.

Why are twist drills pointed?
The point geometry reduces the cross‑cut area at the tip, lowering friction and required feed forces; by sharpening (pointing) a Twist Drill the cutting forces decrease and the tip centres more reliably in the workpiece.

Can a Twist Drill be used to drill wood?
A metal Twist Drill can be used in wood, but the guidance is inferior and the hole finish is usually less clean compared with dedicated Wood drills; however, metal Twist Drills are easier to resharpen and show less self‑pulling action.
