Twist Drill — Type N short HSS‑G, 4.8 mm, 135°, TIN‑coated

The Twist Drill Type N short bit is a precision metal‑working drill for Drilling Machines, designed for stable, fast holes in alloyed and unalloyed steels and other non‑ferrous metals.

• Short geometry for higher stability and precision
• TIN‑coated surface for reduced wear and friction
• Fully ground shaft (HSS‑G) for sharp cutting and clean holes
• 135° tip angle optimised for hard materials like stainless steel
• Conforms to DIN 338 for short cylindrical shank twist drills

Precision and faster machining thanks to short, ground geometry

Short overall length combined with a fully ground HSS‑G flute geometry delivers significantly improved stability and a reduced tendency to deflect. Because the spiral length and overhang are smaller, the bit permits more accurate positioning and straighter holes even under higher cutting forces. The ground flute profile produces very sharp cutting edges, enabling up to 40% faster drilling and a requirement of roughly 50% less feed force compared with conventional HSS bits, which translates directly into less operator fatigue and higher productivity on the shop floor.

Long tool life and lower friction with TIN coating

A Titanium Nitride (TIN) coating forms a hard, wear‑resistant layer that reduces adhesion and heat build‑up at the cutting edge. When used with an appropriate coolant, the TIN‑coated surface noticeably lowers friction and abrasive wear, extending service life during serial or heavy‑duty metal drilling. This treatment is especially beneficial for machining alloyed and unalloyed steel, cast iron, copper alloys and hard plastics, where surface hardness and temperature can cause rapid tool degradation without coating.

Optimised tip and spiral for hard materials and clean entry

The 135° tip angle and Type N normal spiral make this bit especially suitable for harder workpiece materials such as stainless steel and temper castings. A larger tip angle reduces initial bite time and improves centring when starting a hole, while the standard spiral geometry supports efficient chip evacuation in metalworking. Conformity with DIN 338 ensures that dimensions and tolerances meet recognised standards for short cylindrical‑shank twist drills, supporting predictable performance in production environments.

Built for professional users and demanding applications

Manufactured as part of the Profi Line by MetavCUT, this short Twist Drill is aimed at professionals who require repeatable accuracy and durability in metal drilling operations. The bit suits stationary and portable Drilling Machines used in workshops and industrial settings. For tasks where rigidity, precise hole quality and reduced runout are priorities, the compact design and ground construction make this tool an efficient choice.

FAQ

What is the main use of the MetavCUT Twist Drill Type N short?
The MetavCUT Twist Drill Type N short is primarily used for machining high‑strength materials and larger diameters in metalworking. Its short form provides greater stability and precision, and the combination of HSS‑G material and TIN coating makes it durable under high loads when used with suitable cooling.

Which three drill types exist and where does the MetavCUT Twist Drill fit?
There are three common drill categories: metal drills, wood drills and stone/concrete drills. The MetavCUT Twist Drill Type N short belongs to the metal drill group and is optimised for cutting steels, cast materials and non‑ferrous metals.

Can the MetavCUT Twist Drill be used for drilling wood?
A metal‑type twist drill such as the MetavCUT Twist Drill can be used in wood, but guidance and hole finish are typically inferior compared with dedicated wood drills. Metal drills are easier to resharpen and show less self‑feeding, which may be an advantage or disadvantage depending on the task.

Why is the tip of a twist drill often sharpened?
The tip sharpening reduces the cross‑cut at the point of the Twist Drill, which lowers friction and hence the required feed force. A sharpened tip also improves centring at drill start, resulting in cleaner, more accurate holes and less tool wander.
