Twist Drill — 8 mm, 135° Point Angle, Extra Long, Bright Finished, HSS-G (DIN 1869) by MetavCUT

The Twist Drill is an extra long Twist Drill designed for deep metal drilling with a 135° point angle for use in Drilling Machines.

• 8 mm Diameter for precise metal drilling
• Extra-Long Design for deep or hard-to-reach holes
• 135° Point Angle for harder materials
• HSS-G Fully Ground for fast, accurate cuts
• DIN 1869 Standard for deep-hole drilling reliability

Drill Deeper with Consistent Precision

The Twist Drill Extra-Long construction provides an extended Overall Length of 305 mm and a Spiral Length of 210 mm, enabling reliable Deep Drilling where standard tools fall short. This geometry is especially useful when access is limited or when holes must be made from a greater distance; the Longer Reach reduces the need for extensions and preserves alignment. The 8 mm Diameter maintains good rigidity while allowing fine control, so each hole stays true and Repeatable even at depth.

Built for Hard Materials and Stable Entry

Equipped with a 135° Point Angle, this Twist Drill penetrates harder materials with reduced walking and improved centring. The HSS-G Material and CNC grinding process create very sharp cutting edges and high Roundness Accuracy, producing clean bore surfaces in alloyed and unalloyed Steel, Cast Steel, Grey Cast Iron and Non-Ferrous Metals. Note that the ground geometry offers excellent precision but requires appropriate coolant and often stationary or guided use to avoid brittle breakage.

Faster Drilling with Lower Feed Forces

The Fully Ground flute geometry of this Drill allows up to 40% faster drilling and can require up to 50% less feed force compared with conventional rolled HSS designs. This reduction in Thrust improves operator comfort and extends tool life under the right conditions. Conforming to DIN 1869, the deep-spiral form supports effective chip evacuation during long bores and reduces the risk of chip packing that can stall the cut.

Reliable Choice for Workshop and Production Use

Designed for use in Hand Drills and Drilling Machines, the MetavCUT Extra-Long Twist Drill suits workshop environments and stationary machines where repeatability and reach matter. Professionals who machine thicker components or require access past fixtures will value the combination of Precision and Reach. The Standard Line modelling focuses on robust everyday performance and predictable results in series or single-part production.

FAQ

For what is the Twist Drill used?
The MetavCUT Twist Drill is primarily applied for machining high-strength materials and larger bore diameters; it performs well in alloyed and unalloyed Steel, Cast Steel and Non-Ferrous Metals. Its ground spiral geometry is easy to regrind and withstands higher loads, making it suitable for demanding metalworking tasks.

Which three drill types exist?
In general tool classification you will find Metal Drills, Wood Drills and Stone/Concrete Drills; the MetavCUT Twist Drill belongs to the Metal Drill group and is optimised for metalworking applications.

Why are Twist Drills pointed?
The pointing reduces the cross-cut at the tip of the Twist Drill, significantly lowering friction and therefore the required feed force; this sharpening also improves centring of the tip in the workpiece for a more accurate start.

Can a Twist Drill be used to drill wood?
A Metal Drill such as the MetavCUT Twist Drill can be used in Wood, but guidance and finish are inferior compared with wood-specific bits. Metal Drills are easier to resharpen and have less self-feeding action, so results in Wood are acceptable but not optimal.

For which drilling depths is the Twist Drill most commonly used?
A full-penetration bore is often executed with a Twist Drill; for diameters up to 20 mm and depths up to 100 mm this type of tool is the most frequently used option for reliable deep-hole drilling.

What is better, HSS or HSSE?
The common assumption that HSSE steels are universally superior to HSS is not correct. When choosing, evaluate whether the specific work conditions justify the higher cost of HSSE; MetavCUT supplies HSS-G variants that balance performance and economy for many metalworking tasks.
