Twist Drill — Extra Long HSS‑G Twist Drill, 4.5 mm, 135°, Bright Finished, Fully Ground, DIN 1869 (MetavCUT)

The Twist Drill is an extra long HSS‑G drill designed for deep metal drilling with a 135° point angle for reliable centring and efficient penetration.

• Extra long design for deep hole access
• HSS‑G fully ground for precise bore quality
• 135° point angle for harder materials
• Bright finished surface for corrosion protection
• Compatible with Handheld Drilling Machines

Faster, cleaner metal drilling for demanding tasks

The HSS‑G composition of this Twist Drill delivers a combination of hardness and toughness optimised for metalworking. Because the flutes are CNC ground rather than rolled, the tool achieves high roundness accuracy and razor‑sharp cutting edges, which produce cleaner Holes and extend tool life under appropriate cooling. One major benefit is the documented performance gain: the ground HSS design can drill up to 40% faster and requires up to 50% less feed force compared with conventional HSS variants, making it particularly efficient for alloys and unalloyed steels.

Designed for deep-hole applications and accessibility

With a Spiral Length of 160 mm and an Overall Length of 235 mm, this extra long Twist Drill reaches depths that standard lengths cannot. The extended geometry is ideal when drilling in confined or hard‑to‑reach positions, or when a longer reach is needed from a Drilling Machine or handheld device. The tool’s bright finished surface eases chip evacuation and reduces surface friction during long penetration depths, supporting stable, repeatable results.

Optimised geometry for hard materials and precision

The 135° Point Angle of this Twist Drill reduces walking and improves centring when working with harder Metals such as stainless steel or cast materials. The fully ground shank ensures superior concentricity in chucks, translating into better hole tolerances and lower run‑out. For users needing precision bores in components, this geometry offers a clear advantage: faster initial engagement and a reduced tendency for the tool to skid during the start of the cut.

Practical guidance: use, cooling and sharpening

Although the ground HSS design gives excellent cutting performance, users should note the material can be more brittle than rolled types and benefits from correct application. Apply steady cutting speeds, adequate coolant and moderate feed to avoid chipping. The Twist Drill is easier to regrind when required, and the sharpened geometry reduces radial forces, meaning less effort during re‑sharpening. For stationary machine work and workshop conditions, cooling and secure clamping are recommended to maximise service life.

FAQ

What materials can the Twist Drill (MetavCUT Twist Drill) be used on?
The MetavCUT Twist Drill is intended primarily for metalwork; its HSS‑G composition and 135° point angle make it suitable for legierte und unlegierte Stahl, Gussstahl, Gusseisen, Sintereisen, Temperguss, Nichteisenmetalle and hard plastics where precision and durability are required.

Is the MetavCUT Twist Drill suitable for handheld drilling machines?
Yes, the MetavCUT Twist Drill can be used with a Handheld Drilling Machine, but due to its extra long geometry and the ground HSS design, stable clamping, reduced feed forces and adequate cooling are advised to prevent chipping and ensure safe operation.

For what is a Twist Drill used?
A Twist Drill is mainly applied when machining high‑strength materials and larger bore diameters; the form is easy to regrind and endures higher loads, which is why the MetavCUT Twist Drill is chosen for demanding metalworking tasks.

Which three drill types exist?
The three main drill types are metal drills, wood drills and stone/concrete drills; the MetavCUT Twist Drill belongs to the metal drill category and is optimised for such applications.

Why are Twist Drills sharpened?
Sharpening reduces the cross‑edge at the tip of the Twist Drill, which lowers friction and therefore decreases required feed forces, while improving centring and initial penetration of the MetavCUT Twist Drill.

Can the MetavCUT Twist Drill be used to drill wood?
A metal drill can be used in wood, but guidance and finish are inferior compared with dedicated wood bits; the MetavCUT Twist Drill can cut wood but may show poorer tracking and a less clean hole while being easier to regrind and exhibiting lower self‑feed characteristics.

At which drilling depths is the Twist Drill most commonly used?
A through‑hole in solid material is commonly executed with a Twist Drill. For diameters up to 20 mm and depths up to 100 mm, the Twist Drill is the most frequently used tool, and the extra long MetavCUT variant is especially useful for deeper requirements.

What is better, HSS or HSSE?
The general belief that HSSE is always superior to HSS is not universally true. Consider whether your working conditions actually justify the higher purchase cost of HSSE before deciding; the MetavCUT HSS‑G grade may already meet many demanding applications.
