Twist Drill — 4 mm HSS‑G, 135° Tip, DIN 338, Spezial Series

The Twist Drill is a precision metal‑drilling bit for Drilling Machines, engineered for fast, burr‑free holes in alloyed and unalloyed steels as well as non‑ferrous metals.

• Up to 40% faster drilling performance
• Reduced feed force by 50% for easier machining
• 135° tip for hard materials and stainless steel
• HSS‑G material for increased wear resistance
• Multi‑bevel cutting edge, cylindrical shank design

Faster, more efficient metal drilling for workshops and industry

The specially ground HSS‑G geometry of this Twist Drill delivers significantly improved cutting action: users benefit from up to 40% faster drilling and 50% less feed force compared with conventional HSS bits. This translates into shorter cycle times and reduced operator fatigue when working on tougher materials. The result is consistent, burr‑reduced holes and fewer rework steps, which increases productivity in production workshops and maintenance shops alike.

Reliable centring and clean entry for hard materials

A 135° tip angle gives the Twist Drill better centring and a gentler entry into harder materials such as stainless steel, reducing the tendency to wander and lowering burr formation at the hole edge. With a Spiral Length of 43 mm and an Overall Length of 75 mm, the geometry supports stable chip evacuation and controlled drilling depth on typical metalworking tasks. Proper tip geometry means cleaner holes with less need for subsequent deburring.

Conforms to DIN 338 for short cylinder‑shank twist drills

Designed and classified according to DIN 338, this short Twist Drill with cylindrical shank is suitable for stationary and portable Drilling Machines. The multi‑bevel cutting edge (with W‑point, without triangular shank) improves cutting performance and lifetime, especially when machining Cast Steel, Gusseisen, Sintered Iron, Tempered Casts, Aluminium and many engineering plastics. The standardized design ensures interchangeability and reliable performance in production environments.

Ideal users, applications and practical handling tips

This Twist Drill is aimed at professional machinists, toolrooms and industrial maintenance teams who require repeatable quality in metal drilling. For best results use appropriate cutting speeds and coolant for the material, clamp the workpiece securely, and match the drill speed to the material hardness. If unsure about speeds, coolant type or suitability for a specific application, METAV Werkzeuge offers competent technical advice and support to help select the right tool and parameters.

FAQ

What is the Twist Drill used for and which materials are suitable?
The MetavCUT Twist Drill is primarily used for machining high‑strength materials and larger hole diameters; it performs well in alloyed and unalloyed steel, cast materials, non‑ferrous metals and certain plastics. Its ground geometry is easy to resharpen and designed to withstand higher loads during drilling.

Which three drill types are commonly distinguished?
Common drill categories are metal drills, wood drills and stone/concrete drills; the MetavCUT Twist Drill belongs to the metal drill category and is optimised for metalworking applications.

Why are Twist Drills point‑sharpened?
Point sharpening reduces the cross‑cut at the tip, which lowers friction and requires less feed force; as a result the MetavCUT Twist Drill centres more reliably and produces cleaner hole entries with reduced burr formation.

Can a metal drill be used to drill wood?
A metal drill such as the MetavCUT Twist Drill can be used in wood, but guidance and surface finish are typically inferior to a dedicated wood drill. Metal drills are easier to resharpen and have less self‑pulling action compared with specialised wood bits.
