Twist Drill — Short HSS‑G, 7.5 mm, 135° Tip, Type N, TiN‑coated (MetavCUT)

A Twist Drill short Type N for Drilling Machines, designed for precision metalworking and high stability in hard materials.

• Short design for higher stability and accuracy
• TiN‑coating reduces friction and extends tool life
• HSS‑G fully ground for fast, clean metal drilling
• 135° tip optimized for hard and stainless steels
• Conforms to DIN 338 for consistent industrial quality

Precision and stability from a short design

The short design of this HSS‑G Twist Drill reduces the exposed length from the chuck, resulting in markedly higher stability and less deflection during operation. This makes the bit particularly suitable for precision tasks and for drilling in hard materials where accuracy matters. Reduced vibration leads to cleaner holes and less wear on both tool and machine, which benefits production workflows and workshop maintenance.

Coating and material deliver longer life under load

Equipped with a TiN‑coating, the cutter benefits from lower friction at the cutting edge, which decreases heat build‑up and abrasion when drilling metals. The base material HSS‑G (ground high speed steel) provides sharp geometry and high hardness. Combined, these features increase durability when working with alloyed and unalloyed steels, cast iron, copper, bronze and hard plastics, while recommended coolant use further extends service life.

Geometry and norm for demanding metalwork

With a 135° tip angle and Type N (normal spiral) geometry, the bit enters harder materials with reduced walking and improved centering, shortening approach time on tough workpieces. Manufacturing to DIN 338 ensures standardized dimensions and performance expectations for short twist drills with cylindrical shanks, so compatibility with industrial clamps and fixtures is assured. The fully ground flutes also enable up to ~40% faster penetration and lower required feed force compared with conventional HSS variants.

Who benefits and how to use it best

Metalworkers, toolrooms and industrial maintenance teams will appreciate the combination of short length, TiN surface and ground geometry for demanding tasks. For best results, secure the workpiece, use recommended spindle speeds for 7.5 mm HSS bits, and apply suitable cutting fluid to minimise wear. The short Twist Drill is ideal for stationary drilling machines but can also be used in hand drilling machines when stability is ensured.

FAQ

Is the MetavCUT Twist Drill suitable for stainless steel and other hard alloys?
The MetavCUT Twist Drill (Type N) is designed for metalworking and, with its 135° tip and TiN coating, is well suited for alloyed and unalloyed steels as well as other hard metals; using coolant is recommended to maximise tool life.

What does "fully ground" mean for the MetavCUT Twist Drill and why is it important?
Fully ground (HSS‑G) indicates that the flute geometry is produced by CNC grinding rather than rolling, giving the MetavCUT Twist Drill very sharp edges, excellent run‑out accuracy and cleaner holes—advantages especially valuable when machining metalen components.

What is a Twist Drill mainly used for?
A Twist Drill by MetavCUT is primarily applied when machining high‑strength materials and larger diameters; its form is easy to regrind and remains robust under high loads.

Which three drill types exist?
The common categories are Metal drills, Wood drills and Stone/Concrete drills.

Why are Twist Drills point‑sharpened?
Point‑sharpening reduces the web thickness at the tip of the Twist Drill, which significantly lowers friction and the necessary feed forces while improving centring in the workpiece.

Can a metal Twist Drill be used for wood?
A metal (HSS) drill can be used in wood, but guidance and hole finish are generally inferior compared with dedicated wood drills; metal bits are easier to resharpen and have less self‑feeding tendency.

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

Is HSS or HSSE better?
The idea that HSSE is categorically superior to HSS is not universally true; decide based on actual working conditions and whether the performance justifies higher costs for HSSE materials.
