Twist Drill Spiralbohrer – Twist Drill, 2.5 mm Ø, 135° tip, extra long, bright finished, fully ground, HSS‑G (DIN 1869)

A Twist Drill Spiralbohrer designed for deep, precise metal drilling in Drilling Machines and hand-held drills.

• Extra-long design for deep holes
• HSS‑G fully ground for faster, precise drilling
• 135° tip angle for harder materials
• Conforms to DIN 1869 for demanding applications

High-performance material for demanding Metalwork

HSS‑G construction delivers a combination of hardness and cutting-edge geometry that benefits metalworking tasks. The fully ground flute geometry provides sharp cutting edges and high runout accuracy, which results in cleaner holes and less rework. According to internal data, the ground HSS design can enable up to 40% faster drilling while requiring approximately 50% less feed force compared with conventional rolled HSS bits, improving efficiency in production and workshop environments.

Built for deep holes and tough materials

The extra long overall length of 225 mm with a spiral length of 150 mm makes this Twist Drill especially suitable when access is limited or when long through-holes are needed. The 135° tip angle is optimised for harder materials — it reduces initial biting and shortens approach time into the workpiece, which is advantageous when drilling stainless steel and other high-strength alloys up to 1000 N/mm².

Precision geometry and recommended usage

The fully ground (CNC‑ground) flute and shank ensure high concentricity and precise hole quality, which is particularly important for metal and hard-plastic applications. Ground Twist Drills are sharper and generally produce superior surface finish; however, they can be relatively more brittle than rolled types. For best results, use the MetavCUT Twist Drill in stationary Drilling Machines with appropriate cooling and controlled feed to extend tool life.

Typical applications and target users

This Twist Drill is intended for professional machinists, maintenance technicians and metalworking shops that require reliable deep-hole performance. It is suitable for legierte und unlegierte Stahl (alloyed and unalloyed steel), Gussstahl, Gusseisen, Sintereisen, Temperguss, Nichteisenmetalle and hard plastics. The Extra Long design supports drilling operations where standard-length bits are insufficient, while the DIN 1869 specification assures compatibility with industrial production standards.

FAQ

Is the MetavCUT Twist Drill suitable for stainless steel and high-strength alloys?
The MetavCUT Twist Drill is designed to machine materials such as stainless steel and other high-strength alloys up to around 1000 N/mm²; its 135° tip and HSS‑G ground geometry help reduce drilling forces and improve centring in tougher materials.

Can the MetavCUT Twist Drill be used in a hand-held drill?
The MetavCUT Twist Drill can be used in hand-held drills for lighter tasks, but optimal performance and tool life are achieved in a stationary Drilling Machine with adequate clamping and coolant due to the Extra Long design and ground geometry.

What is a Twist Drill used for?
A Twist Drill is mainly applied to the machining of high-strength materials and larger drill diameters; its ground geometry is easy to re‑sharpen and resists heavier loads, making it suitable for demanding metal drilling.

Which three drill types exist?
The three main drill categories are metal drills, wood drills, and stone/concrete drills.

Why are Twist Drills sharpened?
Sharpening reduces the cross‑edge at the drill point; by re‑pointing the tip, frictional forces are substantially lowered so that less feed force is needed and the drill centres more accurately in the workpiece.

Can you drill wood with a Twist Drill?
A metal Twist Drill can be used in wood, but guidance and finish are generally inferior compared with dedicated wood drills; metal bits are easier to re‑sharpen and have less self‑feeding tendency.

For which drilling depths is the Twist Drill most commonly used?
A through-hole in solid material is typically made with a Twist Drill; for diameters up to 20 mm and drilling depths up to 100 mm, the Twist Drill is the most frequently used tool.

What is better, HSS or HSSE?
The common belief that HSSE is automatically superior to HSS is not universally correct; assess the working conditions to determine whether the higher cost of HSSE is justified for your application.
