Extra-long HSS-G twist drills for deep-hole precision
These extra-long twist drills to DIN 1869 are engineered for exceptionally deep or hard‑to‑reach bores, providing reliable penetration and clean chip removal in heavy workpieces and fixture repairs. Manufactured from high‑performance, ground HSS‑G with a polished, uncoated finish and a 135° split point, they deliver superior self‑centring, reduced wandering and lower feed forces for precise starts without pre‑spotting. The ground flutes and razor‑sharp cutting edges ensure friction‑reducing chip evacuation over the extended flute length, while regular clear‑out cycles preserve tool life and process safety. Ideal for extreme depth drilling and maintenance work, these long‑reach drills offer consistent centring, excellent chip flow and robust performance.

9mm HSS-G Twist Drill DIN 1869 ,extra long, bright finished - MetavCUT
Twist Drill — Extra Long Twist Drill, 9 mm, 135° tip, HSS‑G, Bright Finished (MetavCUT) The Twist Drill is an extra‑long HSS‑G drill designed for deep metal drilling with a 9 mm diameter and a 135° tip for hard materials. Extra‑long design for deep, hard‑to‑reach holes 9 mm Diameter for precise metal drilling 135° Tip angle optimised for harder materials HSS‑G ground for fast, clean cuts DIN 1869 compliant for demanding deep‑hole work Precision and performance for deep metal holes The MetavCUT extra‑long HSS‑G twist drill combines a generous overall length with a long Spiral to enable deep‑reach drilling where standard lengths fall short. Thanks to the fully ground flute geometry, the bit produces very sharp cutting edges and high run‑out accuracy, which results in cleaner, more precise holes in metals. For workshop and industrial environments this means fewer re‑cuts, improved fit‑up of components and more predictable machining results under challenging conditions. Faster cutting with less feed force The ground HSS‑G material and optimised geometry allow up to 40% faster drilling and require up to 50% less feed force compared with conventional HSS drills. This makes the tool especially effective when working with alloyed and unalloyed steel, cast steel, cast iron and non‑ferrous metals. The 135° tip angle reduces initial cutting resistance and improves centring on harder materials, shortening set‑up time and increasing throughput on serial operations. Reliable choice for demanding standards and deep drilling Conforming to DIN 1869, this twist drill is built for deep‑hole applications and tougher conditions. The Spiral length of 280 mm and total length of 410 mm are tailored for situations that require extended reach without compromising hole quality. Because the flutes are formed by CNC grinding rather than rolling, users benefit from superior surface finish and dimensional accuracy—features that matter when subsequent machining or assembly demands tight tolerances. Practical workshop guidance and safe use When using this extra‑long Twist Drill in tougher materials, stationary mounting and adequate cooling are recommended to avoid brittle fracture and to extend tool life. The fully ground shank supports better clamping accuracy in chucks and collets, reducing vibration and ensuring concentricity. For operators less familiar with deep‑hole techniques, using modest spindle speeds, steady feed and cutting fluid will deliver the best balance between speed and tool life. Who benefits from this tool This drill is aimed at metalworkers, toolrooms and maintenance professionals who require extended reach and high‑quality holes in harder materials. Whether producing components in small series or performing repair work on assemblies where access is limited, the MetavCUT twist drill offers a practical combination of depth capability and metal‑cutting performance.

The MetavCUT Twist Drill (extra‑long HSS‑G Twist Drill) is particularly suited to alloyed and unalloyed steel, cast steel, cast iron, sintered iron, malleable iron, non‑ferrous metals and hard plastics, offering robust performance where higher strength and precision are required. Is the MetavCUT Twist Drill suitable for very deep holes? Yes, the MetavCUT extra‑long Twist Drill is designed for deep holes: its extended overall length and the Spiral length make it suitable for deep‑reach applications, and compliance with DIN 1869 underlines its suitability for demanding drilling tasks. For what is a Twist Drill used? It is mainly used for machining high‑strength materials and large bore diameters. This design is easy to resharpen and withstands higher loads. Which three drill types exist? There are metal drills, wood drills and stone/concrete drills. Why are Twist Drills tipped/sharpened? Sharpening reduces the secondary cutting edge at the tip of the Twist Drill, lowering friction forces and thus requiring less feed force while improving centring in the workpiece. Can a metal Twist Drill be used to drill wood? A metal drill can be used in wood but gives poorer guidance and a less clean result; it is easier to regrind and has lower self‑feeding characteristics. For which depths is the Twist Drill the most used tool? A full‑bore hole is made with a Twist Drill. For diameters up to 20 mm and depths up to 100 mm, the Twist Drill is the most commonly used tool.
Drill extreme depths with confidence and clean chip evacuation
The series 34 HSS‑G extra‑long twist drill (DIN 1869) is a specialist tool engineered for machining tasks where standard long drills fall short. Designed for exceptionally deep holes and hard‑to‑reach positions, this ground, bright twist drill combines extended reach with features that actively reduce the risk of breakage during deep drilling.
How this drill solves deep‑hole challenges in production
The tool is produced from HSS‑G and precision ground to a polished finish. Its extra‑long overall and flute length, defined by DIN 1869, allows one‑pass through very thick workpieces or access behind interfering edges in jig and fixture work. The machined, very smooth flutes and blank (uncoated, polished) surface minimise friction and help prevent chip adhesion on soft materials such as aluminium or certain plastics. The 135° split point with cross grind provides fast self‑centring and reduces the need for prior centre punching, stabilising the drill at the point of contact and lowering required feed force.
Proven benefits that matter on the shop floor
- Reduced tool breakage risk through improved chip evacuation and razor‑sharp, ground cutting edges
- Greater reach for deep or obstructed holes thanks to the extra‑long DIN 1869 design
- Better centring and easier plunge drilling with the 135° split point and cross grind
- Lower friction and less built‑up edge on soft, adhesive materials courtesy of the bright, polished surface
- Predictable process behaviour when combined with peck drilling (regular clearing) to avoid chip jams

FAQ
Is the series 34 HSS‑G extra‑long twist drill suitable for aluminium and plastics?
Yes. The polished, uncoated surface and ground flutes of the series 34 HSS‑G extra‑long twist drill reduce chip adhesion on soft aluminium and many plastics, though regular pecking to clear chips remains essential for deep holes.
Do I need to centre‑punch before using this deep‑reach twist drill?
In many cases the 135° split point with cross grind gives reliable self‑centring so a centre punch is often unnecessary; however, stable clamping and correct machine setup are still recommended for best results.
What drilling technique is recommended for such an extra‑long twist drill?
Use controlled feed rates, frequent peck drilling (chip clearing), and adequate clamping. The geometry and smooth flutes optimise chip evacuation, but regular clearing is mandatory to prevent chip packing and tool breakage.
How does the split point improve process reliability?
The 135° split point with cross grind reduces thrust force at contact, stabilises the drill during plunge, and minimises walking or run‑out—benefits that are particularly valuable when drilling deep or from awkward access angles.
