Twist Drill — Long HSS‑G 8 mm, 135° Point, DIN 340, Bright Finished Drill Bit

A Twist Drill by MetavCUT is a long HSS‑G 8 mm drill bit for drilling machines, engineered for deep, precise metal bores.

• Long version for deeper and hard‑to‑reach bores
• Fully ground shaft for high concentricity and clean holes
• 135° point angle optimised for harder materials
• Conforms to DIN 340 for consistent overall length and quality
• Bright finished surface for corrosion resistance and easy chip evacuation

High‑performance geometry for efficient metal drilling

The long HSS‑G design combines extended reach with a ground spiral that provides faster penetration and reduced required feed force compared with rolled bits. This construction is particularly advantageous when working with alloyed and unalloyed steels, cast materials and hard plastics: the fully ground flute geometry yields sharp cutting edges and excellent runout accuracy. For users who need deeper bores or access to recessed holes, the extended overall length ensures reach without compromising hole quality.

Cleaner holes and better centring on tough workpieces

A 135° point angle reduces walking and improves centring when entering tough materials such as stainless steel. The reduced chisel edge from the point geometry lowers friction and allows for smoother entry, meaning less burr formation and cleaner bores. When paired with appropriate coolant and moderate speeds, the bit delivers precise, repeatable results that decrease post‑processing and rework.

Built for workshops and drilling machines

This Twist Drill is intended for use with standard drilling machines and is specified to DIN 340, which defines the longer execution for deep drilling tasks. The bright finished surface improves chip flow and offers basic corrosion protection during storage and operation. Its characteristics make it suitable for professional machinists and maintenance workshops that require a reliable, stable standard drill for a broad range of metalworking applications.

Recommendations for use and tool care

To maximise tool life and performance, use coolant when machining harder alloys and observe recommended cutting speeds for HSS‑G material. Because fully ground HSS bits can be more brittle than rolled variants, avoid shock loading and prefer stationary machines or well‑supported power drills. Regular sharpening restores cutting geometry; ground bits are straightforward to regrind to maintain the original precision and cutting behaviour.

FAQ

What is a Twist Drill used for?
The MetavCUT Twist Drill is mainly used for drilling in metal; it is especially suited for machining high‑strength materials and larger diameters where deeper or recessed bores are required. Its ground geometry allows precise holes and reliable centring even in demanding workpieces.

Which three drill types are there?
The main categories are metal drills, wood drills and stone/concrete drills. The MetavCUT Twist Drill belongs to the metal drill group and is optimised for that application.

Why are twist drills sharpened at the tip?
The tip sharpening reduces the chisel edge at the drill point, which significantly lowers friction and required feed force. As a result the MetavCUT Twist Drill centres better in the workpiece and cuts with less resistance.

Can a metal twist drill be used to drill wood?
A metal drill such as the MetavCUT Twist Drill can be used in wood, but guidance and finish are inferior compared with dedicated wood drills. Metal bits are easier to resharpen and typically exhibit less self‑feeding action than wood‑specific designs.

At what drilling depths is the twist drill most commonly used?
A twist drill is the standard tool for through‑hole drilling in solid material. For diameters up to around 20 mm and depths up to approximately 100 mm, the twist drill is the most frequently used tool; the long version of the MetavCUT Twist Drill extends this capability for deeper holes.
