Twist Drill — Long HSS‑G Twist Drill, Diameter 7.5 mm, Tip Angle 135°, Bright Finished, Fully Ground Shank, DIN 340 — MetavCUT Standard Line

The Twist Drill is a long‑version HSS‑G drill designed for deep, accurate metal drilling with a 7.5 mm diameter and a 135° tip angle for harder materials.

• Long design for deep or hard-to-reach holes
• 7.5 mm Diameter for precise hole making
• 135° Tip Angle optimised for harder steels
• Fully ground HSS‑G for high precision and clean holes

Efficient deep-hole drilling with less effort

The Twist Drill in long execution delivers a clear advantage when deeper holes or recessed bores are required. The extended overall length (156 mm) and spiral length (102 mm) allow access to poorly reachable drilling positions without extensions. Thanks to the HSS‑G material and CNC‑ground flute geometry, the bit achieves reduced feed force and up to faster material removal compared with rolled counterparts, which increases productivity on metalworking tasks while maintaining precise hole quality.

Geometry and material that improve performance on tough materials

A 135° tip angle reduces initial cutting load and is particularly suitable for harder materials such as stainless and tempered steels. The fully ground shank and flute geometry produce very sharp cutting edges and excellent running accuracy, resulting in cleaner, more accurate holes. The drill complies with DIN 340 long‑version standards, making it a reliable choice for professional metalworking where repeatable precision matters. For non‑specialist users: HSS‑G means High Speed Steel, ground for superior sharpness and concentricity.

Practical suitability and target applications

This long HSS‑G twist drill is intended primarily for Drilling Machine use on metalwork: alloyed and unalloyed steel, cast materials (including grey and spheroidal graphite cast iron), sintered iron and non‑ferrous metals, as well as hard plastics. Its construction makes it ideal for workshop tasks requiring deep, through or blind holes up to moderate diameters. The bright finished surface improves chip evacuation and visibility when aligning holes, aiding consistent results in serial production or maintenance work.

Usage tips for longevity and best results

For best performance with the MetavCUT long twist drill, use appropriate cutting speeds, coolant and moderate feed to avoid undue stresses; ground drills can be more brittle than rolled types and benefit from controlled machining conditions. Centering and pilot holes improve hole quality in harder materials, while occasional resharpening restores geometry — an advantage of ground HSS bits is straightforward regrinding. Always secure the workpiece and use a suitable chuck for optimal concentricity.

FAQ

What materials can the MetavCUT Twist Drill reliably machine?
The MetavCUT Twist Drill (long HSS‑G twist drill) is designed for metalworking and performs well in alloyed and unalloyed steel, cast steels, grey and spheroidal graphite cast iron, sintered iron, non‑ferrous metals and hard plastics; it is optimised for tougher materials thanks to the 135° tip.

Is the MetavCUT Twist Drill suitable for deep holes and recessed bores?
Yes, the long execution of the MetavCUT Twist Drill provides greater overall and spiral length for deep or hard‑to‑reach holes, making it well suited to through‑holes and blind bores where a standard‑length bit would be too short.

What are twist drills used for?
Twist Drills are primarily applied to the machining of high‑strength materials and for larger drill diameters. Their ground form allows easier regrinding and they withstand greater loads, making them suitable for deep holes or when access is restricted.

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

Why are twist drills point‑sharpened?
Point sharpening reduces the cross‑edge at the tip of the Twist Drill, which significantly lowers friction and required feed force while improving centring of the drill in the workpiece.

Can a metal Twist Drill be used to drill wood?
A metal (HSS) drill can be used in wood, but guidance and hole finish are inferior compared with dedicated wood drills. Metal drills are easier to resharpen and exhibit less aggressive self‑pulling.

For which drilling depths is the Twist Drill most commonly used?
Solid drilling is often performed with a Twist Drill. For diameters up to 20 mm and drilling depths up to 100 mm, the Twist Drill is the most commonly used tool.

Which is better, HSS or HSSE?
The general belief that HSSE is categorically superior to HSS is incorrect. When choosing, assess whether the working conditions justify the higher acquisition cost of HSSE for your specific application.
