Twist Drill (Type N) — Short HSS‑G Metal Drill, Ø 8.5 mm, 135°

The Twist Drill (Type N) is a short, bright‑finished HSS‑G drill designed for precision metalworking in drilling machines and hand drills.

• Short design for high stability and precision
• HSS‑G ground tip for clean, accurate holes
• 135° tip angle optimised for hard materials
• Fully ground shank for excellent concentricity
• Conforms to DIN 338 for short twist drills

Precision and faster penetration in hard metals

The Profi Line short Twist Drill brings measurable efficiency to metalworking: the HSS‑G ground geometry reduces required feed force and enables up to 40% faster drilling compared with conventional HSS types. With a 135° tip angle, the drill enters hard materials more smoothly and reduces wandering on the surface, so one clean, centred hole is achieved with less rework. This results in time savings and improved process reliability for daily workshop tasks.

Greater stability and reduced deflection during drilling

A reduced overall projection improves stiffness: the short execution (total length 117 mm, spiral length 75 mm) minimises bending and vibration when compared with longer drills. The shorter overhang leads directly to better hole accuracy and longer tool life in many setups. The fully ground shank ensures reliable clamping and concentricity in standard drill chucks and machine spindles, lowering runout and improving surface quality of the bore.

Designed for a wide range of metalworking applications

This Twist Drill (Type N) is tailored for demanding tasks: ideal for alloyed and unalloyed steel, cast steel, cast iron, sintered iron, non‑ferrous metals and hard plastics. The normal spiral geometry of Type N provides a balanced chip evacuation and cutting action suited to general metal drilling. Use in stationary drilling machines or appropriately rated hand drills delivers consistent results when standard cooling and speeds for the material are observed.

Manufacturing standard, sharpening and recommended handling

Manufactured to DIN 338, the drill is produced with CNC grinding of the flute geometry (HSS‑G), which gives very sharp cutting edges and a high degree of concentricity. Ground drills can be more brittle than rolled variants; therefore, application with coolant and controlled feeds is recommended to avoid breakage. For maintenance, regrind the lip and chisel edge respecting the original 135° tip to retain centring performance and chip formation characteristics.

Who benefits from this Profi Line Twist Drill

Workshop professionals and maintenance technicians who require fast, precise holes in tough materials will value the combination of short design and ground HSS quality. The tool is particularly useful where repeatable accuracy and reduced setup time matter, for example in toolrooms, small series production or repair work. METAVCUT’s specification focuses on dependable performance for metalworking environments.

FAQ

What is the MetavCUT Profi Line Twist Drill mainly used for?
The MetavCUT Profi Line Twist Drill (Type N) is primarily used for drilling into high‑strength and hard metals; it performs especially well in alloyed and unalloyed steel, cast iron and similar materials where a durable, accurate hole is required.

Can the MetavCUT Profi Line Twist Drill be used in a hand drill?
Yes, the MetavCUT Profi Line Twist Drill can be used in suitably rated hand drills as well as in stationary drilling machines, provided the chuck secures the fully ground shank correctly and recommended speeds and cooling are applied.

For what is a Twist Drill used?
A Twist Drill is mainly applied to the machining of high‑strength workpieces and larger drill diameters. This shape is easy to sharpen and withstands higher loads.

Which three drill types exist?
There are three primary drill categories: Metal Drill, Wood Drill, and Stone/Concrete Drill.

Why are Twist Drills sharpened?
Sharpening reduces the cross‑edge at the tip of the Twist Drill, significantly lowering friction so that less feed force is needed and the tip centres more reliably in the workpiece.

Can a metal drill be used to drill wood?
A metal drill can be used in wood, but guidance is poorer and the finish is less clean; however, these drills are easier to re‑sharpen and have lower self‑feed tendency.

At which drilling depths is the Twist Drill the most used tool?
A through‑hole in solid material is commonly executed with a Twist Drill. For diameters up to 20 mm and depths up to 100 mm, the Twist Drill is the most frequently used tool.

What is better, HSS or HSSE?
The widespread belief that HSSE is always superior to HSS is not universally true. Evaluate working conditions carefully to determine whether the higher cost of HSSE is justified for your application.
