Twist Drill — Type N short, Ø 4.5 mm, 135°, HSS‑G, bright finished, DIN 338

A short Twist Drill (Type N) designed for precise metalworking with drilling machines and hand drills.

• Short design increases rigidity and precision
• Ground HSS-G for sharp cutting and clean holes
• 135° tip for hard materials like stainless steel
• Suitable for drilling machines and handheld drills
• Conforms to DIN 338 for short cylindrical shank drills

Precision and stability for demanding metalwork

The short execution of this Twist Drill reduces overhang and therefore bending, delivering noticeably higher stability during machining. With a diameter of 4.5 mm and an overall length of 80 mm, the compact geometry is ideal for tight setups and precise centre‑to‑centre tolerance work. The Type N spiral is the classic geometry for metal drilling, while the DIN 338 designation guarantees standardised dimensions and performance expectations for short cylindrical‑shank drills.

Faster cutting with lower feed force

A ground HSS‑G flute geometry enables up to 40% faster drilling and requires about 50% less feed force compared with conventional HSS variants under comparable conditions. This means shorter cycle times and reduced operator exertion when producing series holes in alloyed and unalloyed steels, cast steels, sintered irons and certain hard plastics. The 135° tip reduces initial point pressure and improves centring when entering harder materials, shortening dwell time on the workpiece surface.

Applications and machine compatibility

This Twist Drill is developed for drilling metal: steel, cast iron, non‑ferrous metals and hard plastics. It is suitable for both stationary drilling machines and portable hand drills where increased rigidity and accurate hole quality are required. The fully ground shank aids consistent clamping in chucks and collets, and the bright finished surface supports chip evacuation and inspection. Use coolant for deep or continuous cuts to preserve tip life and hole quality.

Handling, life cycle and practical tips

Because the flutes and geometry are produced by CNC grinding, the drill offers high runout accuracy and very sharp cutting edges, giving clean bores and reduced burr formation. Note that ground HSS drills can be more brittle than rolled variants; avoid excessive shock and use machine‑steady feeds. Re‑sharpening is possible but should be performed by experienced toolmakers to retain geometry. For optimal results, pair the drill with appropriate cutting speeds and lubricants for the specific metal being machined.

FAQ

What materials is the MetavCUT Twist Drill Type N best suited for?
The MetavCUT Twist Drill Type N is primarily intended for metalworking and performs well in alloyed and unalloyed steel, cast steel, cast iron, sintered iron, non‑ferrous metals and hard plastics, offering reliable hole quality when used with correct speeds and cooling.

Can the MetavCUT Twist Drill be used in a hand drill?
Yes, the MetavCUT Twist Drill is suitable for both stationary drilling machines and hand drills (Drilling Machine), but the short design particularly benefits setups that demand rigidity and precision; always ensure secure clamping and compatible cutting parameters.

What are twist drills used for?
Twist Drills are mainly applied when machining high‑strength materials and larger hole diameters; their form is easy to regrind and resists higher loads, making them suitable for demanding metalworking operations.

Which 3 drill types exist?
The three primary drill categories are metal drills, wood drills and stone/concrete drills.
