Twist Drill 8.5 mm HSS-G (Extra Long, 135°) — bright finished, fully ground, DIN 1869 by MetavCUT

The Twist Drill 8.5 mm HSS-G is an extra-long metal drill designed for deep, high-precision holes in demanding materials for Drilling Machines.

• Extra-long length for deep, hard-to-reach holes
• HSS-G material for precise metal drilling
• 135° point angle for harder materials like stainless steel
• Fully ground shank for high concentricity
• DIN 1869 compliant with 305 mm overall length

Outstanding Performance through Material and Geometry

The extra-long HSS-G construction combines high cutting performance with improved hole quality. Thanks to the fully ground flute geometry, the bit achieves very sharp cutting edges and excellent run-out accuracy, which reduces wobble and delivers cleaner holes in alloys and cast materials. This design also means lower required feed force compared with roll-formed equivalents, so machining becomes more efficient and precise.

Ideal for Deep and Difficult Metal Drilling

Engineered specifically for deep drilling, the extended Spiral Length (210 mm) and Overall Length (305 mm) enable work in recessed or hard-to-reach areas where standard lengths fail. The 135° point angle reduces entry forces and improves centring in tougher metals, making the tool well suited for applications in alloyed and unalloyed steel, cast steel, cast iron and other non-ferrous metals. For production or repair work that demands depth and accuracy, this bit keeps processes reliable.

Practical Machining Advice and Terminology Explained

For safe and efficient use, employ appropriate coolant and moderate cutting speeds when machining harder alloys. The term HSS-G denotes High-Speed Steel, ground (HSS-G), meaning the flute geometry is ground rather than rolled—this yields sharper cutting edges and superior concentricity but can be more brittle, so stationary setups or rigid chucks and cooling are recommended. The 135° tip is chosen to shorten the initial boring time and to suit harder materials; a larger point angle typically reduces the tendency to grab and improves surface finish.

Who Benefits Most from This Tool

Production shops, tool rooms and maintenance teams facing deep-metal drilling tasks gain immediate advantages from the extra reach and precision. The bit is aimed at professionals who require consistent hole quality in challenging materials and those who value reduced rework. Its compliance with DIN 1869 ensures predictable performance in industrial environments, while the bright finished surface aids in chip evacuation and corrosion resistance during storage.

FAQ

What materials is the Twist Drill by MetavCUT suitable for?
The Twist Drill from MetavCUT (Twist Drill / Drill for Metal) is designed for alloyed and unalloyed steel, cast steel, cast iron, sintered iron, tempered castings, non-ferrous metals and hard plastics; its HSS-G composition and 135° tip support drilling in tougher metals with improved hole quality.

How does the extra-long design affect drilling performance with the MetavCUT Twist Drill?
An extra-long Twist Drill by MetavCUT lets operators reach recessed bores and deep workpieces that standard lengths cannot access; it maintains chip evacuation over longer depths but requires rigid fixturing and proper cooling to avoid breakage and to preserve concentricity.

For what is a Twist Drill used?
A Twist Drill is primarily applied when machining high-strength materials and larger hole diameters; it is easy to regrind and withstands higher loads, making it suitable for demanding metalworking tasks and deep-hole operations.

Which three drill types exist?
The three main drill types are Metal drills, Wood drills, and Masonry/Concrete drills.
