Introducing the Twist Drill — Left-cutting HSS-G Twist Drill for Drilling Machine, 9.5 mm, 135° (DIN 338) by MetavCUT

The Twist Drill is a left-cutting HSS-G drill for Drilling Machines, optimised for metalworking and particularly suitable for extracting broken or seized screws in counterclockwise operations.

• Left-cutting geometry for screw extraction
• 9.5 mm Diameter for medium-size metal holes
• 135° Point Angle for harder materials
• Manufactured to DIN 338 standard
• HSS-G material for high wear resistance

Faster metalworking and safer screw extraction with left-cutting geometry

Left-cutting drills are designed to cut effectively in counterclockwise rotation, which makes them especially useful when a drilling task aims to remove broken or stuck screws. The Left-cutting grind reduces torsional stresses on the workpiece and often causes the screw remnant to rotate out as the drill advances. In practice, this means less time spent on difficult extractions and a reduced need for secondary extraction tools. The left-hand design also helps to prevent accidental forward self-feed in certain setups, increasing process control during repair work.

High-performance HSS-G for durability under stress

Made from HSS-G, this drill offers a balance of hardness and toughness that suits alloyed and unalloyed steels, Cast Steel, Cast Iron, and non-ferrous metals. The material choice provides improved heat resistance and wear performance during continuous metal cutting tasks. For users who need dependable tool life in workshop or on-site repairs, the HSS-G composition reduces the frequency of regrinding and replacement compared with softer grades, translating into lower downtime and higher overall efficiency.

Optimised 135° point angle for demanding materials

A 135° point angle reduces the tendency to wander at the start of a hole and improves centring when working with harder materials such as stainless steel. This geometry distributes cutting forces over a larger area, shortening the initial bite time and often allowing faster feed without compromising hole quality. For precise repair operations or when working with tougher alloys, the sharper angle contributes to cleaner entry and more consistent hole profiles.

Compliance with DIN 338 and suitability for machine applications

Produced to DIN 338, this short twist drill with cylindrical shank follows established dimensions and tolerances for machine use. Conformance to the standard ensures interchangeability and predictable behaviour in rotating machine tools, whether stationary or portable Drilling Machines. The standardised form also simplifies tool selection for workshops that require consistent performance across different diameters and makes reconditioning processes more straightforward.

Who benefits from this drill and how to apply it

Crafted for technicians, maintenance engineers and professional metalworkers, the left-cutting Twist Drill from MetavCUT excels where controlled counter-rotation and resilience are required. It is ideal for extraction tasks, repair operations and general metal drilling up to medium diameters. When used with a machine capable of left-hand rotation and appropriate coolant or cutting lubricant, the drill achieves higher penetration rates and reduced operator effort compared with conventional HSS variants.

FAQ

What is the Twist Drill used for and when is left-cutting advantageous?
The MetavCUT Twist Drill with left-cutting geometry is mainly used for machining high-strength materials and for larger diameter holes where counterclockwise cutting helps. Left-cutting is particularly advantageous for extracting broken or seized screws because the reverse rotation often aids removal while reducing required feed force.

Which three drill types exist and where does the Twist Drill fit?
Common types are metal drills, wood drills and stone/concrete drills. The MetavCUT Twist Drill belongs to the metal drill category and is optimised for metallic materials and machine-driven operations.

Why are Twist Drills re-ground to a point angle and what does a 135° angle achieve?
Re-sharpening adjusts the Cutting Edges and the Point Angle to reduce the chisel edge and lower friction. A 135° Point Angle, as used on the MetavCUT Twist Drill, shortens initial penetration time and improves centring in harder materials, allowing smoother drilling with less tendency to wander.

Can the MetavCUT Twist Drill be used for wood drilling?
A metal Twist Drill can be used in wood, but guidance and finish are generally inferior compared with a dedicated wood drill. The MetavCUT Twist Drill will drill wood but may give a rougher hole and less precise guidance, while being easier to re-sharpen and having a lower self-feed tendency.

For which hole depths is the Twist Drill the most used tool?
A full-through drilling operation is commonly executed with a Twist Drill. For diameters up to 20 mm and drilling depths up to 100 mm, the Twist Drill such as the MetavCUT model is the most frequently used tool in workshops and machine shops.
