Twist Drill — Long HSS‑G Twist Drill, 4.5 mm, 135° tip, Bright finished, Fully ground, DIN 340

The Twist Drill is a long‑version metal drilling bit designed for deep and hard‑material drilling with drilling machines and hand drills.

• Long design for deeper, hard‑to‑reach holes
• 135° tip for reliable entry into hard materials
• Fully ground HSS‑G for precise, clean holes
• DIN 340 standard for industrial compatibility

Reach deep holes reliably with the long design

The long execution of this Twist Drill (Total Length 126 mm, Spiral Length 82 mm) is ideal when holes must be drilled far from the workpiece edge or in recessed positions. The extended Spiral Length reduces the need for extensions or special fixtures, allowing deeper boreholes with consistent chip evacuation. This makes the bit particularly useful in maintenance, toolroom tasks, and assembly work where access is limited and reliability matters.

Faster cutting and easier feed thanks to fully ground HSS‑G

The HSS‑G material and fully ground flute geometry provide a sharper cutting edge and high concentricity. Compared with rolled HSS variants, a ground Twist Drill can cut up to 40% faster and requires significantly less feed force, which reduces operator fatigue and improves spindle load behaviour. The ground geometry also creates cleaner hole walls in alloyed and unalloyed steels, cast materials and non‑ferrous metals.

Optimised tip geometry for harder materials

A 135° tip angle reduces the tendency to wander on hard surfaces and shortens initial penetration time in tough materials such as stainless steels. The flatter tip distributes cutting forces better and is recommended when drilling high‑strength steels and cast materials up to the limits specified by the DIN 340 family. For best results, combine with appropriate coolant and moderate spindle speeds to balance tool life and surface finish.

Practical guidance for use and durability

The bright finished surface improves corrosion resistance and visual inspection, while the fully ground shank ensures a secure clamping fit in drill chucks. Although ground HSS bits can be more brittle than rolled types, correct coolant use and controlled feed rates extend service life considerably. For stationary machining and demanding metalworking applications, the Standard Line model offers a balanced compromise between performance and tool robustness.

FAQ

Can this Twist Drill be used in a hand drill or only in a machine?
The MetavCUT Twist Drill is suitable for both drilling machines and hand drills, but for best precision and tool life use in a stable chuck with controlled speeds; heavier use in stationary machines with coolant is recommended for harder materials.

What is a Twist Drill used for?
A Twist Drill is primarily applied to the machining of high‑strength materials and larger bore diameters; it is relatively easy to regrind and withstands high cutting loads, making it suitable for alloyed and unalloyed steels, cast materials and other demanding applications.

Which three drill types are there?
The main drill categories are metal drills (such as HSS Twist Drills), wood drills, and stone/concrete drills.
