Twist Drill — 7 mm, 135° tip, long, bright finished, HSS‑G, DIN 340

The Twist Drill long HSS‑G 7 mm is built for deep metal drilling with a 135° tip, suited to hard materials and less accessible bore locations on a Drilling Machine.

• Long Twist Drill for deep, hard-to-reach holes
• HSS-G ground for faster drilling and precise holes
• 135° tip suited for hard materials like stainless steel
• Fully ground shank ensures high runout accuracy
• DIN 340 standard for long drill execution

Faster deep drilling with reduced effort for workshop use

Long execution according to DIN 340 offers clear practical benefits: the increased Spiral Length and overall length enable drilling into deeper workpieces or into recesses where standard bits fall short. Because the flute geometry is ground, the bit cuts with very sharp edges, which can result in up to 40% faster drilling and requires substantially lower feed pressure compared with conventional HSS bits. The practical effect is less operator fatigue, more consistent bore quality and a faster cycle time for repetitive metalworking tasks.

Precise holes in hard materials thanks to HSS‑G and 135° tip

A HSS‑G (ground high‑speed steel) blank combined with a 135° tip improves centring and reduces walking on harder substrates such as stainless steel. The ground geometry gives high Runout Accuracy and clean chip evacuation, producing more concentric and burr‑reduced holes. Users benefit from better repeatability and less post‑processing. Note that ground HSS bits can be more brittle than rolled types, so controlled feeds and appropriate coolant are advised to avoid chipping.

Built for metalworking: materials and machine compatibility

This long variant is intended primarily for metallic materials: alloyed and unalloyed steel, cast steels, grey and spheroidal cast iron, sintered iron, non‑ferrous metals and hard plastics. It is compatible with handheld Drilling Machines and bench drills when greater reach is needed. For drilling in steels up to the typical range of 900 N/mm² the geometry and tip angle help maintain performance while minimising chatter and deflection, delivering holes that meet machining tolerances in assembly and maintenance operations.

Practical handling advice to extend service life and hole quality

Because the flutes and cutting geometry are produced by grinding, re‑sharpening is straightforward and preserves cutting performance. For best results, use moderate cutting speeds, steady feed and regular cooling or lubrication to manage heat and chip formation. When drilling deep bores, peck drilling or intermittent withdrawal will improve chip evacuation and reduce risk of breakage. Store bits to avoid impact and inspect for wear before reuse to ensure continued precision.

FAQ

What is this Twist Drill suitable for?
The MetavCUT Twist Drill long 7 mm is suitable for metalworking tasks where deeper or less accessible holes are required; the HSS‑G ground geometry and 135° tip make it especially effective for alloyed and unalloyed steels, cast materials and hard plastics.

Which three drill types exist?
There are three common drill categories: metal drill bits, wood drill bits and stone/concrete drill bits; the MetavCUT Twist Drill belongs to the metal drill bit family and is optimised for that application.

What is a Twist Drill used for?
A Twist Drill is principally used for machining high‑strength materials and larger bore diameters; its shape is easy to re‑grind and it endures higher loads while keeping a sharp cutting edge.
