Twist Drill — left-cutting HSS‑G metal drill, Ø 7 mm, 135° (DIN 338) by MetavCUT

The Twist Drill is a left‑cutting metal drill bit for Drilling Machine use, designed for fast, precise removal of broken or seized screws and reliable machining of alloyed and unalloyed steels.

• Left‑cutting geometry for screw extraction and reverse drilling
• HSS‑G material for high wear resistance
• 135° point angle for harder materials like stainless steel
• Conforms to DIN 338 for short cylindrical shank bits
• Optimised cutting: up to 40% faster drilling with less thrust

Faster results when extracting screws and working in reverse

The left‑cutting geometry of this bit gives a decisive advantage when encountering broken or jammed screws: the cutting lips are ground so the drill cuts correctly in left rotation, which often helps to unscrew and remove the damaged fastener while drilling. This construction also reduces the tendency to pull the bit into the workpiece and, in many cases, allows for a more controlled extraction process. The left‑cutting feature therefore converts a common workshop problem into a predictable, solvable task.

Durable performance through HSS‑G and Profi Line engineering

Manufactured from HSS‑G, this Twist Drill offers elevated hardness and heat resistance compared with standard HSS grades, resulting in longer tool life under high loads. The Profi Line design emphasises dimensional accuracy and consistent edge geometry, so wear patterns remain predictable and regrinding is straightforward. For users who need repeatable performance in tougher materials, the combination of HSS‑G and professional series quality translates into fewer tool changes and less downtime.

Optimised point angle for hard materials and reduced walking

A 135° point angle is specified for improved centring and longer edge life when machining harder materials such as stainless steel and cast components. The flatter point reduces penetration shock and helps avoid chatter at the start of a hole. In practical terms, this means cleaner entry holes and better control when drilling alloys and tempered steels, especially in combination with an appropriate coolant and steady feed.

Standardised dimensions for reliable machine compatibility

This Twist Drill is produced to DIN 338, the classification for short twist drills with cylindrical shank, which ensures compatibility with a wide range of bench and portable drilling machines. The Ø 7 mm diameter and standard shank dimensions permit quick clamping and stable rotation in chucks and collets. Choosing a DIN‑compliant bit reduces the risk of misfits and simplifies tool inventory management for workshops and industrial operations.

Practical benefits for workshop and maintenance applications

Beyond material and geometry, this bit is tailored for real workshop needs: reduced thrust force during cutting can make hand‑held drilling less strenuous and improve operator control, while the left‑cutting option expands the bit’s usefulness for maintenance tasks such as extracting corroded or stripped screws. The resulting time savings and increased first‑pass success rate benefit both craftspersons and production teams with frequent metalworking demands.

Simple explanation of key terms for everyday use

If the terminology is unfamiliar, here is a brief guide: left‑cutting means the flutes and cutting edges are ground to cut effectively when the spindle turns counterclockwise; HSS‑G is a high‑speed steel grade with enhanced properties for heavy cutting; a 135° point angle produces a flatter tip suited to hard materials; and DIN 338 specifies short, cylindrical‑shank twist drills commonly used in metalworking. These characteristics combine to make the bit a specialist solution rather than a general‑purpose wood or masonry tool.

FAQ

What is the Twist Drill from MetavCUT best used for
The MetavCUT Twist Drill is primarily intended for metalworking, with a particular strength in extracting broken or seized screws thanks to its left‑cutting geometry; it is also suitable for drilling alloyed and unalloyed steels when used in a Drilling Machine.

Does the MetavCUT Profi Line Twist Drill require a special machine?
The MetavCUT Profi Line Twist Drill needs a drilling machine capable of running in reverse (left rotation) to exploit the left‑cutting grind; for conventional forward drilling the same DIN 338 bit shape is compatible with standard chucks, but screw‑extraction performance requires left rotation.

For what is a Twist Drill used
A Twist Drill is mainly applied to the machining of high‑strength materials and larger drill diameters; the shape is easy to regrind and withstands higher loads, which makes it suitable for demanding metalwork and repair tasks.

Which three drill types exist
There are three principal drill types: Metal drills, Wood drills, and Stone/Concrete drills.

Why are twist drills pointed
Pointing a Twist Drill reduces the cross‑cut at the tip; this lowers friction and therefore reduces required thrust force while improving centring of the drill tip in the workpiece.

Can a Twist Drill be used for wood
A Metal drill can be used in wood, but guidance and finish will be inferior compared with a purpose‑made wood drill; metal drills are easier to regrind and usually have less self‑feeding action.

For which drilling depths is the Twist Drill most used
A through hole in solid material is commonly produced with a Twist Drill; for diameters up to 20 mm and drilling depths up to 100 mm the Twist Drill is the most frequently used tool.

Is HSS or HSSE better
The common belief that HSSE steels are always superior to HSS is incorrect; you should evaluate whether the working conditions justify the higher cost of HSSE before deciding.
