Twist Drill (Drill for Metal) — 8.5 mm, 135° Point Angle, HSS‑G, Extra Long, Bright Finished, Fully Ground Shank, DIN 1869

The Twist Drill from MetavCUT is a precision Drill for Metal designed for deep, accurate holes in hard materials using a fully ground HSS‑G geometry.

• Extra long for deep and hard-to-reach holes
• HSS‑G ground design for clean, precise holes
• 135° point for easier entry in hard materials
• Fully ground shank for secure chuck grip
• Compliant with DIN 1869 for deep drilling

High-precision geometry for cleaner holes and faster drilling

The extra-sharp HSS‑G material and CNC-ground flute geometry deliver consistently precise results when machining steels and non-ferrous metals. This design produces sharp cutting edges and excellent roundness, which means cleaner holes and less rework. Thanks to the optimised geometry, users can achieve up to 40% faster drilling and require up to 50% less feed force compared with conventional HSS bits, reducing operator fatigue and machine load.

Built for deep drilling — reliable chip evacuation and stability

With an overall length of 390 mm and a spiral length of 265 mm, this Extra Long configuration is intended for deep bore applications where standard lengths fall short. The DIN 1869 specification and the deep-spiral flute aid in effective chip evacuation under extended cutting conditions, lowering the risk of clogging and improving hole quality in deep stacks or confined workpieces.

Suitable for demanding metalworking tasks and machine setups

The MetavCUT Twist Drill is targeted at machinists, toolroom technicians and maintenance professionals who require robust performance in legated and unlegated steels, cast iron and hard plastics. The Fully Ground Shank ensures accurate clamping and concentricity in chucks and toolholders, while the bright finished surface supports smooth insertion and corrosion resistance during storage.

Best practices for longevity and performance

To maximise life and performance, operate the bit with appropriate speeds and feeds for the specific metal and use coolant or cutting lubrication for sustained duty cycles; this is especially important given the ground geometry’s brittleness compared with rolled designs. The 135° point angle reduces walking and shortens piercing time in harder alloys such as stainless steel. For optimal results, prefer stationary or well-supported drilling setups and avoid abrupt lateral loads.

FAQ

What is the MetavCUT Twist Drill best used for?
The MetavCUT Twist Drill (Drill for Metal) is primarily used for machining high-strength materials and larger diameters where durability and precision are required. Its ground HSS‑G geometry is well suited to drilling in alloyed and unalloyed steels, cast iron and hard plastics, and it performs reliably in deep-hole situations.

Which three drill types exist?
There are three common drill categories: metal drills, wood drills and stone/concrete drills. The MetavCUT Twist Drill belongs to the metal drill group and is designed specifically for metalworking applications.

What is a Twist Drill used for?
A Twist Drill is mainly applied when working with high‑strength materials and larger bore diameters. Its ground form allows precise sharpening, and it withstands higher loads, making it suitable for drilling alloys, cast steels and hard plastics.
