Twist Drill (Drill Bit) — MetavCUT Extra Long HSS‑G, 7.5 mm, 135° Point Angle, Bright Finished, Fully Ground, DIN 1869

The Twist Drill by MetavCUT is an extra‑long HSS‑G drill bit designed for deep metal drilling in drilling machines, combining increased reach with precise, ground geometry for reliable industrial use.

• Extra‑long design for deep hole drilling
• HSS‑G material for higher cutting performance
• 135° Point Angle optimized for hard metals
• Fully ground shank for excellent concentricity
• Conforms to DIN 1869 for demanding conditions

Engineered reach and reliability for deep drilling

This extra‑long Twist Drill delivers extended reach where standard lengths fall short. The increased Overall Length and Spiral Length make it suitable for deep Holes and hard‑to‑access bore positions, reducing the need for extensions or special fixtures. Because the Flute Geometry is produced by CNC grinding, the bit offers consistently sharp cutting edges and improved chip evacuation, which helps maintain cutting performance over longer penetrations and under higher loads.

Ground geometry for precise, clean holes

The Fully Ground HSS‑G construction results in very accurate concentricity and sharp cutting lips, producing cleaner bores in metal. A 135° Point Angle reduces walking and spreads cutting forces for tougher materials such as alloyed and unalloyed steels. For users, this means fewer re‑drills, better hole quality and improved fitment for subsequent assembly operations. Use with appropriate coolant and steady feed to avoid brittle breakage tendencies common to ground HSS tools.

Material choice and what it means for performance

Constructed from HSS‑G, this bit balances hardness and wear resistance with the grindability required for precision tools. HSS‑G is particularly suited to metalworking tasks—casting, steel, sintered materials and certain plastics—where a sharp, ground flute profile improves hole finish. For those less familiar: HSS‑G indicates a High Speed Steel tool that has been ground (G) rather than roll‑formed, giving superior edge geometry and surface finish at the expense of slightly higher brittleness.

Recommended use cases and handling advice

Best results are achieved when the bit is used in a suitable Drilling Machine with stable clamping, controlled feed and coolant. The extra length is designed for deep bores up to substantial depths while preserving accuracy; avoid excessive side loads and use reduced speeds for very hard materials. When regrinding is necessary, the ground geometry allows relatively simple resharpening, but caution is advised to maintain the correct Point Angle and lip geometry to preserve centring and cutting behaviour.

Who benefits from this tool and why

This tool is aimed at professional workshops and industrial fabricators who require reliable deep drilling in metals. The combination of DIN 1869 compliance, fully ground shank and extra‑long design makes it a practical choice for machinists tackling components with recessed or hard‑to‑reach bore locations. For users seeking cleaner holes and consistent tool life in challenging materials, the HSS‑G extra‑long design provides a measurable advantage.

FAQ

What is the MetavCUT Twist Drill used for and which materials suit it best?
The MetavCUT Twist Drill (drill bit) is primarily used for drilling in metal; it is especially effective on alloyed and unalloyed steel, cast iron, sintered metals, temper cast and non‑ferrous metals, as well as hard plastics where a precise bore is required.

Which three main drill types exist?
The primary drill categories are metal drills, wood drills and stone/concrete drills, covering the typical material families and tool geometries needed for different substrates.

For what purpose are twist drills mainly used?
Twist Drills are mainly applied to machining high‑strength materials and larger drill diameters; their form is easy to regrind and they withstand higher loads while maintaining hole quality.

Why are twist drills pointed (what is the purpose of the point)?
Pointing reduces the secondary cutting edge at the tip; by resharpening the point, friction is lowered, which reduces required feed forces and improves centring of the tip in the workpiece for more accurate starts.

Can the MetavCUT Twist Drill be used to drill wood?
A metal‑grade twist drill can be used in wood, but guidance and surface finish are generally inferior compared with dedicated wood bits. The metal bit is easier to resharpen and has lower self‑feeding tendency.

At which drilling depths is the twist drill most commonly used?
Solid hole drilling is typically performed with a twist drill. For diameters up to about 20 mm and depths up to around 100 mm, the twist drill is the most frequently used tool.

What is better, HSS or HSSE?
The common belief that HSSE is always superior to HSS is not universally true. Evaluate working conditions carefully to determine whether the higher cost of HSSE is justified for your application.
