Twist Drill — Extra Long HSS‑G Twist Drill for Drilling Machine, Ø 6 mm, 135°, Bright Finished, DIN 1869

The Twist Drill is an extra long HSS‑G drill for metalworking, designed for deep holes and hard materials and optimised for use in a Drilling Machine.

• Extra long design for deep holes
• 135° point angle for hard materials
• HSS‑G ground flutes for precise, clean holes
• Fully ground shank for high concentricity
• DIN 1869 compliant for deep‑hole applications

Precise metal cutting through ground HSS‑G construction

The extra long Twist Drill features a HSS‑G (ground high‑speed steel) geometry that produces very sharp cutting edges and a high degree of precision. Grinding the flutes instead of rolling yields improved Rundlaufgenauigkeit and cleaner hole surfaces, which reduces the need for rework. This construction also allows for faster drilling with lower feed forces compared to conventional HSS designs. Use of coolant and appropriate spindle speeds preserves the cutting edge and extends service intervals.

Designed for deep and difficult access drilling in metals

With an overall length of 330 mm and a spiral length of 225 mm, this extra long design meets the demands of deep bore operations. The 135° point angle makes the bit particularly suitable for harder materials such as alloyed and unalloyed steel and cast iron, where a larger point angle shortens initial cutting time. Conforming to DIN 1869 for deep‑hole capability, the geometry manages chip evacuation under challenging conditions, helping to avoid clogging during extended bores.

Suited for workshops, toolrooms and maintenance operations

The Twist Drill by MetavCUT is intended for professional metalworkers, maintenance teams and toolroom operators who require reliable deep‑hole performance. In a Drilling Machine it excels at producing accurate cylindrical holes in components, and its design is compatible with stationary setups where coolant can be applied. The bit’s characteristics make it especially useful when precision and repeatability matter, for sample preparation, pattern making or repair work.

Handling recommendations to maximise lifetime and safety

Because ground HSS can be more brittle than rolled alternatives, correct feed and cooling are essential: moderate feed rates, continuous cooling and firm clamping are recommended to avoid breakage. The fully ground shank improves runout and grip in the chuck, reducing vibration and improving hole quality. If re‑sharpening is required, the ground geometry permits precise reconditioning; however, rework should be done by experienced staff or in a tool shop to retain the original cutting geometry.

FAQ

What materials is the MetavCUT Twist Drill (Drill for Metal) best suited for?
The MetavCUT Twist Drill (Drill for Metal) is optimised for a range of metals: alloyed and unalloyed steel, cast steel, cast iron and non‑ferrous metals. Its 135° point angle and HSS‑G construction make it particularly effective when machining harder workpieces.

Can the MetavCUT Twist Drill be used in a handheld drill or is it made for machines?
The MetavCUT Twist Drill is specified for use in a Drilling Machine for best results; while it can be fitted to powerful hand drills, performance and service life are maximised in stationary equipment with proper clamping and coolant.

For what is a Twist Drill used?
The Twist Drill is mainly applied when machining high‑strength materials and larger bore diameters. Its shape allows straightforward re‑grinding and it withstands higher loads, making it suitable for demanding metalwork.

Which three types of drill are there?
There are three common drill categories: Metal drills, Wood drills, and Stone/Concrete drills.

Why are Twist Drills point sharpened?
Point sharpening reduces the cross‑cut at the tip of the Twist Drill, which lowers friction and therefore reduces the required feed force; it also improves the drill’s centring in the workpiece for more accurate holes.

Can a Twist Drill be used to drill wood?
A metal Twist Drill can be used in wood, but guidance and surface finish are usually inferior compared to purpose‑made wood drills; metal bits are easier to re‑sharpen and typically show less self‑feeding.

For which drilling depths is the Twist Drill most commonly used?
Twist Drills are the standard choice for through holes and solid material drilling. For diameters up to 20 mm and depths up to 100 mm a Twist Drill is often the preferred tool.

Is HSS or HSSE better for my application?
The idea that HSSE is categorically superior to HSS is not universally correct. Evaluate whether your working conditions justify the higher cost of HSSE; for many applications a well‑made HSS‑G Twist Drill from MetavCUT offers an excellent balance of performance and economy.
