Twist Drill — Type N Short HSS‑G, 8.7 mm, 135°, Bright Finished, DIN 338

The Twist Drill is a short Type N HSS‑G drill designed for precision metalworking in Drilling Machines, offering high stability and clean holes for demanding industrial applications.

• Short HSS‑G design for higher stability
• 8.7 mm diameter for precision metal drilling
• 135° point for hard materials like stainless steel
• Fully ground shank for high runout accuracy
• DIN 338 standard for consistent quality

Improved stability and faster cutting for metalworking

Short design increases rigidity: the short Twist Drill reduces overhang and resists bending, which improves positional accuracy during drilling. The HSS‑G (ground High Speed Steel) geometry enables significantly faster material removal — the manufacturer information cites up to 40% faster drilling with 50% less feed force compared with conventional HSS drills — which directly translates into shorter cycle times and lower operator effort when working with steels and other tough metals.

Tip geometry tailored for harder materials

A 135° point angle is specified to ease entry into hardened surfaces and to reduce chipping when drilling stainless and alloyed steels. For non‑specialists: a larger point angle flattens the tip, spreading cutting forces and reducing the tendency for the drill to "grab", so holes start cleaner and tool life improves under correct cooling and feed. The drill conforms to the Type N normal spiral profile, making it particularly suitable for metal applications rather than soft woods.

Precise shank and manufacturing quality for consistent results

The fully ground shank and ground flute geometry produce high concentricity and sharp cutting edges. Grinding (HSS‑G) rather than roll‑forming creates very sharp cutting lips and excellent roundness, which yields cleaner holes and better dimensional accuracy. Users should note that ground drills can be more brittle than rolled types and therefore benefit from using appropriate coolant and secure clamping in the machine.

Intended applications and user recommendations

Designed primarily as a Drill for Metal, this short Twist Drill excels in workshop and production environments where repeatable accuracy is required: toolrooms, maintenance departments and metal fabrication shops. The 8.7 mm size and 125 mm overall length make it well suited to standard drilling tasks on lathes and drilling machines, especially when drilling in alloyed or unalloyed steel, cast materials and hard plastics. For novice users, using moderate feed and coolant will extend tool life and maintain hole quality.

FAQ

What materials is the MetavCUT Twist Drill Type N suitable for?
The MetavCUT Twist Drill Type N is intended primarily for metalworking; it is suitable for alloyed and unalloyed steels, cast steel, cast iron, sintered iron, temper castings, non‑ferrous metals and hard plastics. The short HSS‑G geometry supports precise drilling in harder materials when used with suitable coolant and machine setup.

How does the 135° point angle affect drilling performance with the MetavCUT Twist Drill?
A 135° point angle on the MetavCUT Twist Drill reduces initial penetration forces and improves centring on hard materials; this larger angle shortens the effective cutting time and helps prevent chipping at the entry, provided the drill is used with appropriate feed and cooling.

For what is a Twist Drill mainly used?
A Twist Drill is most commonly applied to the machining of high‑strength materials and larger hole diameters. It is easy to regrind and withstands higher loads, making it suitable for demanding metal drilling tasks.

Which three drill types are there?
There are three main drill families: Metal drills, Wood drills and Masonry/Concrete drills. The MetavCUT Twist Drill belongs to the metal drill category and is optimised for that purpose.

Why are Twist Drills sharpened (pointed)?
Pointing the tip reduces the cross‑cut at the drill’s tip, which lowers friction and consequently the required feed force; this also improves the drill’s ability to self‑centre in the workpiece for cleaner starts.

Can a Twist Drill be used for drilling wood?
A metal Twist Drill can be used in wood, but guidance and finish are typically inferior to a dedicated wood bit. Metal drills are easier to resharpen and have lower self‑feed, so they are usable in a pinch but do not give as clean results as wood‑specific bits.

At which depths is the Twist Drill most used?
Solid drilling 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.

Is HSS or HSSE better?
The general belief that HSSE is always superior to HSS is incorrect. When choosing between HSS and HSSE, evaluate whether the specific working conditions justify the higher cost of HSSE material.
