Twist Drill — Extra long HSS‑G 7.5 mm, 135° Point, Bright Finished (DIN 1869) by MetavCUT

The Twist Drill is an extra‑long HSS‑G drill designed for deep metal drilling in a Drilling Machine and for demanding machining tasks.

• Extra‑long design for deep drilling
• HSS‑G material for high precision metalwork
• 135° point angle for harder materials
• Fully ground shank for accurate runout
• Conforms to DIN 1869 for industrial use

Durable HSS‑G construction for precision and life

The Twist Drill is manufactured from HSS‑G (ground high‑speed steel), which provides high cutting performance and precise hole quality in metalworking. Ground flutes create very sharp cutting edges and superior concentricity, resulting in cleaner holes and lower vibration. This construction suits applications where drilling accuracy matters and supports stable tool behaviour under machining loads.

Extra‑long geometry for deep and hard-to-reach holes

With an extra‑long overall length and an extended spiral length, this twist drill enables reliable drilling in deep bores and in situations where access is limited. The longer geometry reduces the need for extensions or special setups, allowing deeper penetration while maintaining chip evacuation. For deep drilling, pair the tool with appropriate cooling to reduce thermal stress and prolong tool life.

Point geometry optimised for harder materials

A 135° point angle is specified to improve centring and reduce chipping when working with harder metals such as alloyed steels and cast materials. The flatter tip reduces initial cutting forces and helps maintain tool life under higher contact stresses. This geometry is especially suitable when accuracy and clean entry holes are required in tough workpiece materials.

Application range and recommended use

This twist drill is intended primarily for Drills for metal, including alloyed and unalloyed steel, cast steel, cast iron and certain engineering plastics. The fully ground shank ensures low runout when used in standard drilling machines. For best results, operate with appropriate coolant, moderate feed rates and stable clamping. Where mobility is required, ensure correct speeds and support to avoid breakage.

Who benefits from this tool

Engineers, toolroom technicians and maintenance professionals who need a reliable solution for deep, precise metal holes will benefit from the Twist Drill’s combination of extra length, ground geometry and robust HSS‑G material. The tool is suitable for both production environments and repair operations where hole quality and repeatability are priorities.

FAQ

What materials can the MetavCUT Twist Drill be used on?
The MetavCUT Twist Drill is designed for a wide range of metals; it performs well in alloyed and unalloyed steels, cast steel, cast iron and some hard plastics thanks to its HSS‑G material and 135° point geometry.

Is the MetavCUT Twist Drill suitable for deep boring in production?
Yes, the MetavCUT Twist Drill’s extra‑long design and DIN 1869 compliant flute geometry make it suitable for deep bore applications in production environments when used with proper cooling and stable clamping.

For what is a Twist Drill used?
A Twist Drill is mainly applied for machining high‑strength materials and larger diameters. Its design is straightforward to regrind and it withstands higher loads, making it suitable for demanding metalworking tasks.

Which three drill types exist?
There are Metal Drills, Wood Drills and Stone/Concrete Drills.

Why are twist drills pointed (regrinded)?
Pointing reduces the secondary cutting edge at the tip, which lowers friction and required feed forces while improving centring of the drill in the workpiece.

Can a metal twist drill be used to drill wood?
A metal twist drill can be used in wood but typically has poorer guidance and a less clean finish; however, such drills are easier to resharpen and exhibit less self‑feed.

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

Is HSS or HSSE better for my needs?
The common belief that HSSE is always superior to HSS is not universally correct. Assess whether your working conditions justify the higher cost of HSSE before selecting the tool.
