Twist Drill — Twist Drill, 12 mm, 135°, Extra Long, Bright Finished, Fully Ground, DIN 1869, HSS‑G (MetavCUT)

The Twist Drill is an extra long HSS‑G metal drill designed for deep, precise holes in demanding materials such as alloyed and unalloyed steel.

• Twist Drill 12 mm diameter for deep holes
• Extra long design for deep and hard-to-reach holes
• 135° point angle suited for harder materials
• HSS‑G fully ground for precise metal drilling
• DIN 1869 standard with 480 mm overall length

Engineered for deep, consistent metal drilling with reduced effort

The extra long geometry of this Twist Drill combines a 480 mm overall length with a 330 mm spiral length, making the bit particularly suited for applications where reach is critical. The 12 mm diameter maintains stability while permitting access into recessed or hard‑to‑reach positions. Designed for use on a Drilling Machine, the tool’s construction allows straightforward integration into workshop routines and industrial tasks where deep, straight bores are required.

Faster feeds and cleaner holes thanks to fully ground HSS‑G construction

A Fully Ground HSS‑G designation means the flute geometry is manufactured by CNC grinding rather than rolling, resulting in sharp cutting edges and high concentricity. This produces noticeably cleaner holes and precise guidance in metals. With a 135° point angle, the bit reduces initial deflection on harder materials; the grinding and geometry together enable up to 40% faster drilling and can require 50% less feed force compared with conventional HSS variants under comparable conditions, improving efficiency for repetitive metalworking tasks.

Suitable applications and careful usage recommendations

This tool is intended for metal drilling and performs best in alloyed and unalloyed steel, cast steel, cast iron, sintered iron, tempered cast materials, non‑ferrous metals and hard plastics. Because HSS‑G items can be more brittle than rolled types, the bit is particularly appropriate for stationary setups or when good coolant and stable clamping are available. For portable hand‑held drilling, ensure secure workholding and appropriate cooling to minimise risk and extend service life.

Practical advantages for workshops and maintenance departments

The combination of reach and precision makes this bit valuable for maintenance, toolroom, and fabrication tasks where access is constrained. The bright finished surface eases chip evacuation visibility and inspection, while the DIN 1869 conformity signals suitability for deeper drilling operations under more demanding conditions. Opting for a fully ground HSS variant provides benefits in hole quality and repeatability when machining harder or alloyed materials.

FAQ

How deep can the MetavCUT Twist Drill reach?
The MetavCUT Twist Drill is designed for deep drilling tasks thanks to its extra long geometry: a total length of 480 mm and a spiral length of 330 mm provide extended reach for recessed bores and hard‑to‑access positions on a Drilling Machine.

Which materials is the MetavCUT Twist Drill suitable for?
The MetavCUT Twist Drill in HSS‑G is suitable for alloyed and unalloyed Steel, Cast Steel, Cast Iron, Sintered Iron, Tempered Cast materials, Non‑ferrous Metals and Hard Plastics, delivering precise, repeatable holes when used with appropriate coolant and fixturing.

For what is a Twist Drill used?
A Twist Drill such as the MetavCUT Twist Drill is mainly used when working on high‑strength materials and larger diameters; its geometry lends itself to easy re‑grinding and it endures higher loads, making it a reliable choice for heavy‑duty metalworking.

Which three drill types exist?
The main drill categories are Metal drills, Wood drills and Stone/Concrete drills, each optimised in geometry and cutting edge for their respective materials.

Why are Twist Drills point‑ground?
Point‑grinding reduces the chisel edge at the tip of the Twist Drill, lowering friction and thus the required feed forces; at the same time the ground point improves centring of the tip in the workpiece for more accurate starts.

Can a Metal drill be used for wood?
A Metal drill like the MetavCUT Twist Drill can be used in Wood, but guidance is reduced and the finish may be less clean; however such drills are easier to re‑sharpen and exhibit lower self‑feed behaviour.

At what drilling depths is the Twist Drill most commonly used?
Twist Drills are commonly applied for through‑solid holes; in typical practice they are used for diameters up to 20 mm and drilling depths up to approx. 100 mm, depending on geometry and setup.

What is better, HSS or HSSE?
The general assumption that HSSE is categorically superior to HSS is not universally correct; selection should consider actual working conditions to determine whether the additional cost of HSSE is justified.
