Twist Drill — HSS‑G Extra Long, 3.5 mm, 135° (Bright Finished, Fully Ground Shank, DIN 1869)

The Twist Drill is an extra‑long HSS‑G metal drill designed for deep, precise holes in hard materials when used with a Drilling Machine.

• Extra‑long design for deep hole drilling
• HSS‑G for high performance in hard metals
• 135° Point Angle for stainless steel and alloys
• Fully ground shank for concentricity and precision
• DIN 1869 standard for demanding industrial use

Faster penetration and lower feed force for efficient machining

The Twist Drill from MetavCUT combines an HSS‑G material composition with a ground flute geometry that enables up to 40% faster drilling and requires approximately 50% less feed force compared with conventional HSS drills. This efficiency reduces operator effort and tool wear during repetitive Metalworking tasks, making it particularly suitable for workshops and maintenance operations where throughput matters. The performance advantage translates directly into shorter cycle times and more predictable production.

Precise holes thanks to CNC grinding and optimised point geometry

A fully ground shank and flutes produce a very sharp cutting edge and excellent run‑out behaviour, resulting in cleaner, more accurate holes in tough materials. The 135° Point Angle is optimised for harder materials such as Stainless Steel and alloyed Steels, shortening initial entry time and improving centring. For users unfamiliar with grinding terminology: “fully ground” means the flutes are shaped by CNC grinding rather than rolled, which yields higher concentricity and superior hole finish at the cost of higher brittleness under misuse.

Built for deep and hard‑to‑reach drilling applications

With an Overall Length of 210 mm and a Spiral Length of 145 mm, this extra‑long design is intended for deep hole drilling and access into recessed or hard‑to‑reach areas. The geometry follows DIN 1869 for deep‑hole twist drills and is frequently employed for diameters up to 20 mm and depths approaching 100 mm in many metalworking scenarios. Users should employ adequate clamping and coolant when drilling deep holes to preserve tool life and maintain hole quality.

Clear suitability and targeted user groups

This tool addresses the needs of professional machinists, maintenance technicians, toolroom staff and industrial workshops that require reliable metal drilling performance. The combination of HSS‑G material, sharp CNC grinding and a specialised point angle makes it a good choice for drilling Legated and Unlegated Steel, Cast Iron, Sintered Iron and certain Non‑Ferrous Metals. For hobbyists, the drill can be used in a bench or hand Drilling Machine when setup and coolant are applied correctly.

FAQ

What is the MetavCUT Twist Drill used for?
The MetavCUT Twist Drill is primarily applied in the machining of high‑strength materials and when larger drill diameters are required; its form is easy to sharpen and it withstands substantial loads, which makes it suitable for demanding Metalworking tasks.

Which three basic drill types exist?
For general use, drill types are categorised as Metal Drill, Wood Drill and Stone/Masonry Drill; the MetavCUT Twist Drill belongs to the Metal Drill category and is optimised for metals.

Why are Twist Drill tips often re‑ground?
Re‑grinding the tip of a MetavCUT Twist Drill reduces the cross‑cut at the tip, lowering friction and thus the required feed force while improving centring and drilling control.

Can a Metal Twist Drill be used for 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; however, Metal Drills are easier to re‑sharpen and show less self‑feeding tendency.
