Twist Drill – Extra Long HSS-G Twist Drill, Ø 12 mm, 135° Point Angle, Bright Finished, Fully Ground Shank, DIN 1869

The Twist Drill is an extra long HSS-G drilling tool for Drilling Machine applications, designed for deep-hole metalworking and precise bore guidance.

• Extra long design for deep drilling
• HSS-G ground geometry for precise holes
• 135° Point Angle for harder materials
• Fully Ground Shank for high runout accuracy
• Conforms to DIN 1869 for demanding tasks

Deep-hole capability that reaches further

The Twist Drill Extra Long variant delivers extended Spiral Length and Overall Length to access deep, hard-to-reach positions in metal components. Designed according to DIN 1869, this drill is optimised for drilling in alloyed and unalloyed Steel, Cast Iron and Non-Ferrous Metals. The extra length reduces the need for extensions or multiple setups and helps achieve consistent hole depth in one pass, which benefits workshops and maintenance teams requiring reliable deep-hole performance.

Faster drilling with ground HSS-G geometry

A Fully Ground HSS-G construction means the flutes and cutting geometry are produced by CNC grinding rather than rolling, resulting in very sharp cutting edges and excellent Runout Accuracy. Ground HSS (HSS-G) can enable up to 40% faster drilling and requires lower feed force compared with conventional HSS drills. The geometry also produces cleaner hole surfaces, making post-processing easier. For users less familiar with HSS-G, this term refers to hardened high-speed steel ground to precise tolerances for metal machining.

Built for harder materials and better centring

With a 135° Point Angle, this Twist Drill is tailored for harder materials such as stainless steel and tempered alloys; the larger angle shortens initial bore time and improves centring on tough surfaces. The drill's bright finished surface and precise tip geometry reduce walking during start-up, so even handheld Drilling Machine operations gain from improved guidance. Use of cooling and moderate speeds is recommended to maintain tool life and avoid premature wear.

Practical handling and workshop recommendations

Although ground HSS tools offer superior precision, they can be more brittle than rolled designs; therefore the Twist Drill Extra Long benefits from stationary drilling setups, steady feeds and appropriate coolant. Re-sharpening is possible due to the ground geometry, but it should be performed on suitable grinding equipment to preserve the specified Point Angle and flute profile. For manual drilling tasks, ensure secure clamping and moderate speed to avoid chipping at the tip.

FAQ

What materials is the MetavCUT Twist Drill suitable for?
The MetavCUT Twist Drill (Extra Long, HSS-G) is suitable for a range of metals including alloyed and unalloyed Steel, Cast Iron, Sintered Iron and Non-Ferrous Metals; its ground geometry is especially effective when machining tougher materials.

How does the Fully Ground HSS-G design benefit accuracy?
The Fully Ground HSS-G construction of the MetavCUT Twist Drill produces very sharp cutting edges and high Runout Accuracy, resulting in cleaner, more precise holes and improved centring during drilling.

For what is a Twist Drill used?
A Twist Drill is primarily applied when machining high-strength materials and large drill diameters; its shape lends itself to grinding and it endures greater loads, making it suitable for deep holes and robust metalworking tasks.

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