Twist Drill (Spiralbohrer) — HSS-G long, 4.2 mm, 135°

The Twist Drill (Spiralbohrer) is a long HSS-G drill bit designed for deep metal drilling with DIN 340 specification, ideal for use with a Drilling Machine.

• Long HSS-G design for deep holes
• Precise 4.2 mm diameter for accurate results
• 135° tip angle for harder materials
• Fully ground shank for high runout accuracy
• Bright finished surface for reduced adhesion

High performance through HSS-G construction

Designed as a long execution according to DIN 340, this HSS-G tool combines endurance and cutting efficiency. The fully ground geometry ensures sharp cutting edges and a high degree of roundness, which supports up to 40% faster drilling and requires 50% less feed force compared with conventional rolled HSS bits. This results in cleaner holes and less operator fatigue when working with legated and unlegated steels, cast materials and hard plastics.

Deeper holes made accessible and precise

With an overall length of 119 mm and a spiral length of 78 mm, the bit enables drilling in recessed or hard-to-access positions where standard lengths fall short. The 135° point angle improves performance on tougher materials by reducing initial chipping and improving centering, so fewer pilot operations are needed. This geometry is particularly suited to stainless and tempered steels where a flatter point reduces wander.

Accurate handling and machine compatibility

The ground shank and bright finish give excellent seating and reduced friction when clamped in chucks of a Drilling Machine. Because the bit is ground (HSS-G), it provides superior concentricity and hole quality; however, it is comparatively more brittle than rolled types and benefits from steady feed, proper cooling and preferably stationary machine use for maximum service life. The bit is engineered for routine workshop use and professional metalworking environments.

Who benefits most from this design

Production shops, maintenance teams and precision metalworkers will appreciate the combination of long reach and HSS-G performance for demanding tasks such as bushings, deep through-holes and repair work in cast and sintered parts. The tool is a reliable choice when deep, accurate holes in steels and non-ferrous metals are required and when regrinding capability is desirable for tool life extension.

FAQ

For what is a Twist Drill (Spiralbohrer) used?
The Twist Drill from MetavCUT is primarily applied to machining high-strength materials and large drill diameters; its long design supports deeper holes and working in hard-to-reach positions. The ground form is easy to re-sharpen and withstands considerable loads, making it suitable for tougher metalworking tasks.

Which three drill types exist?
Commonly distinguished 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 steels and similar materials.

Why are Twist Drills re-sharpened (ausgespitzt)?
Re-sharpening reduces the cross-edge at the tip, which lowers friction and thus requires less feed force; for the MetavCUT Twist Drill this improves centring and reduces cutting forces during the initial penetration into the workpiece.

Can a metal Twist Drill be used to drill wood?
A metal drill such as the MetavCUT HSS-G Twist Drill can be used in wood, but guidance is poorer and the hole finish is not as clean as with a dedicated wood bit; metal drills are easier to re-sharpen and tend to have less self-feeding action in timber.

For which drilling depths is the Twist Drill most used?
A solid through hole is typically executed with a Twist Drill; for diameters up to about 20 mm and depths up to 100 mm the Twist Drill is the most frequently used tool, and the MetavCUT long execution is well suited for deeper bores.

Is HSS or HSSE better?
The common assumption that HSSE steels are always superior to HSS is not universally true. When choosing, evaluate whether the working conditions justify the higher cost of HSSE; the MetavCUT HSS-G long drill offers excellent performance for many standard applications.
