Twist Drill — 3.8 mm, 135° point, Long HSS‑G, Bright Finished, DIN 340 (MetavCUT)

The Twist Drill is a long HSS‑G metal‑drilling tool for Drilling Machines, engineered for deep holes and hard materials such as alloyed steel.

• Long design for deep or hard‑to‑reach holes
• HSS‑G ground geometry for precise, clean bores
• 135° point angle suited for harder materials
• Fully ground shank for high concentricity
• Compliant with DIN 340 for standardized performance

Deeper holes with reliable cutting performance

This long‑version bit combines HSS‑G material and a ground flute geometry to deliver faster cutting and cleaner hole finishes in metal. The extended Spiral Length of 73 mm and Overall Length of 112 mm allow access to recessed or hard‑to‑reach drilling positions, while the 135° point reduces burr formation in tougher alloys. The CNC grinding process produces sharp cutting edges and consistent flute geometry, which improves chip evacuation and contributes to repeatable accuracy in production and workshop use.

Precision and machine compatibility for metalwork

Designed for use with a Drilling Machine, the fully ground shank ensures excellent Roundness and secure clamping, reducing runout and vibration. The combination of DIN 340 long design and HSS‑G material makes this tool particularly effective for drilling in alloyed and unalloyed steels, cast irons and certain engineering plastics. For tasks requiring steady feed and cooling—such as deep metal bores—the long HSS‑G version maintains tool life and hole quality when used with appropriate coolant regimes.

Practical benefits and working recommendations

As a specialist Twist Drill in the Standard Line, the ground HSS construction requires lower axial force and often drills up to 40% faster than conventional HSS bits of rolled geometry. To maximize service life, use steady speeds, adequate lubrication or coolant, and moderate feed—especially when machining higher tensile materials. The Bright Finished surface aids initial centring and allows simple visual inspection for wear; however, the ground geometry is best suited to stationary or machine‑based applications to minimise breakage risk.

Who benefits from this tool and typical applications

Workshops, toolrooms and professional metalworkers will appreciate the Long HSS‑G bit for tasks such as through‑holes, deep dowel‑holes and repair drilling in ferrous materials. The tool is aimed at users needing precision and depth capability rather than casual or purely wood‑based applications. Because of its hardened geometry and 135° point, it is recommended for machining harder steels where reduced tip penetration and controlled chip formation are required.

FAQ

What is the primary use of a Twist Drill and which materials suit it best?
The MetavCUT Twist Drill is primarily used for machining high‑strength materials and larger drill diameters; it is especially suitable for alloyed and unalloyed steels, cast and sintered irons and certain hard plastics. The long HSS‑G design supports deeper bores and makes the bit easier to resharpen if required.

Which three main drill types exist?
Typical drill classifications are Metal Drills, Wood Drills and Stone/Concrete Drills; the MetavCUT Twist Drill belongs to the Metal Drills category and is optimised for ferrous and non‑ferrous metalworking tasks.

Why are Twist Drills pointed (regrinded) at the tip?
The point grinding reduces the cross‑cut at the tip, lowering friction and therefore required feed force; reprofiling the tip also improves centring in the Workpiece and reduces tool wandering during startup.

Can a Twist Drill be used to drill wood?
A metal Twist Drill like the MetavCUT bit can drill wood, but guidance and finish will be inferior compared with purpose‑made wood bits; metal drills are easier to resharpen and show less self‑feed, yet yield rougher hole edges in timber.

For which hole depths is a Twist Drill most commonly used?
A full solid bore is typically produced with a Twist Drill. For diameters up to about 20 mm and drilling depths up to around 100 mm, the Twist Drill is the most frequently used tool, especially in metalworking operations.

Is HSS or HSSE better?
The general belief that HSSE is always superior to HSS is not universally valid. Evaluate working conditions carefully: the higher acquisition cost of HSSE must be justified by thermal or wear demands of the application before choosing it over HSS.
