Twist Drill — 8 mm, 135° Tip Angle, Extra Long • Bright Finished • HSS‑G • DIN 1869

The Twist Drill is an extra‑long HSS‑G metal drill for deep, precise holes with a Drilling Machine, optimised for hard materials and demanding shop use.

• Extra‑long design for deep drilling
• CNC‑ground HSS‑G for precise, clean holes
• 135° Tip Angle suited for hard materials
• Fully ground shank for excellent concentricity

Consistent deep-hole performance for demanding metalwork

The MetavCUT extra‑long design delivers reliable drilling when access is restricted or when through‑holes must be produced without multiple setups. With a Total Length 390 mm and a Spiral Length 265 mm, this twist drill enables drilling of extended depths while maintaining steady chip evacuation. The elongated geometry reduces the need for extensions or stepped drilling, which saves time in production and lowers fixture complexity. For machinists seeking reproducible deep holes, the geometry is designed to balance stiffness and Reach.

Sharp geometry and material for hard, alloyed steels

Made from HSS‑G and finished by CNC grinding, the bit combines toughness with cutting precision. The 135° Tip Angle reduces cutting forces in harder materials such as stainless and tempered steels, improving centring and lowering the risk of workpiece deformation. Grinding the Flutes produces a sharp cutting edge and high runout accuracy, which results in cleaner bores and more consistent hole tolerances. For operators less familiar with grind types: CNC grinding means the Flute geometry is cut rather than rolled, giving higher Dimensional Precision at the cost of slightly increased brittleness — therefore cooling and appropriate speeds are recommended.

Recommended applications, handling and compatibility

This metal drill is intended for drilling in legated and unlegated Steel, Cast Iron, Non‑Ferrous Metals and Hard Plastics under workshop conditions. It is optimised for use in a Drilling Machine and benefits from controlled speeds, steady feed and coolant for prolonged life. The Fully Ground Shank improves clamping concentricity in chucks, reducing runout and vibration. As a practical tip: when working deep, ensure adequate Chip Evacuation and periodic pecking or coolant supply to prevent clogging and premature wear.

FAQ

What is the MetavCUT Twist Drill best used for?
The MetavCUT Twist Drill (metal Twist Drill) is primarily designed for machining high‑strength and alloyed steels and larger bore diameters; its extra‑long design and HSS‑G material make it suitable for deep holes and applications requiring precise hole geometry.

Can the MetavCUT Twist Drill be used in a bench or handheld drill?
The MetavCUT Twist Drill is optimised for use in a Drilling Machine; it can be used in powerful benchtop machines but, due to its length and ground construction, handheld use is not recommended for safety and accuracy reasons.

For what is a Twist Drill used?
A Twist Drill is mainly applied when machining high‑strength materials and large bore diameters. Its form allows relatively easy regrinding and it endures higher loads, making it suitable for tough metalworking tasks.

Which three drill types exist?
Common categories are Metal Drill, Wood Drill and Masonry/Concrete Drill.

Why are twist drills pointed?
Pointing reduces the cross‑edge at the tip of the twist drill. By pointing, friction forces are significantly lowered so reduced feed forces are required, and the tip centres better in the workpiece.

Can you drill wood with a metal twist drill?
A metal drill can be used in wood, but guidance is poorer and hole quality is inferior. Metal bits are easier to regrind and have less self‑feed, so results may be acceptable for non‑critical wooden applications.

At which drilling depths is the twist drill most used?
Twist Drills are the standard tool for through holes and are most commonly used up to diameters of about 20 mm and drilling depths up to 100 mm; extra‑long variants extend that capability for deeper bores.

Which is better, HSS or HSSE?
The general assumption that HSSE is always superior to HSS is incorrect. Evaluate working conditions carefully to determine whether the higher cost of HSSE is justified for the required application.
