Twist Drill — Extra Long HSS‑G, 5 mm, 135°, Bright Finished, Fully Ground Shank (DIN 1869)

The Twist Drill is an extra long, bright finished metalworking drill designed for Drilling Machine use, offering a 5 mm diameter, 245 mm overall length and a 135° point angle for precise deep-hole metal drilling.

• Extra long design for deep holes
• Fully ground shank for high runout accuracy
• HSS‑G material for hard metals and plastics
• DIN 1869 standard for deep‑hole performance
• 170 mm spiral length for extended cutting reach

High performance drilling power for demanding metalwork

The HSS‑G Extra Long Twist Drill delivers reliable metal removal with optimized cutting geometry. With a 5 mm diameter and 170 mm spiral length within a 245 mm overall length, this drill is built for deep and hard‑to‑reach applications. The 135° point angle reduces initial cutting forces on tougher materials and improves centring, while the bright finish minimises adhesion. The product is particularly suited for drilling alloyed and unalloyed steels, cast irons, sintered materials, non‑ferrous metals and hard plastics, offering measurable efficiency gains compared with standard drills.

Precise, ground geometry for clean holes and reduced effort

CNC grinding of the flute geometry (designation HSS‑G) produces very sharp cutting edges and excellent concentricity, which yields clean, accurate holes and improves tool life under correct conditions. Due to the grinding process, the Twist Drill shows superior runout behaviour and cutting precision compared with rolled equivalents. The trade‑off is higher brittleness; therefore the tool performs best in well‑clamped setups with appropriate cooling. The ground design also supports up to 40% faster drilling and requires up to 50% less thrust under suitable conditions, reducing operator effort on demanding materials.

Designed for professionals who need reach and reliability

This Extra Long Twist Drill targets workshop professionals, maintenance technicians and metal fabricators who require extended reach without sacrificing accuracy. The fully ground shank ensures secure clamping and repeatable concentricity in Drilling Machines and suitable hand drills. For deep bores, long‑reach maintenance tasks or when access is limited, the Extended Spiral Length enables straight, reliable holes. For optimal results, use steady feed, coolant where appropriate and a stable chuck or collet.

Compliance, handling and application guidance

Manufactured to DIN 1869 in the Standard Line, the Twist Drill meets expectations for deep‑hole performance in materials up to approximately 1000 N/mm², including grey cast iron and various steels. The bright finished surface eases chip evacuation in many situations. When selecting operating parameters, match cutting speed and feed to the workpiece material and use cooling for ductile or heat‑sensitive metals. The 135° point angle is particularly advantageous for stainless and other hard materials because it reduces spalling and improves centring during penetration.

FAQ

What materials is the MetavCUT Twist Drill suitable for?
The MetavCUT Twist Drill is designed primarily for metalworking: alloyed and unalloyed steel, cast steel, grey cast iron, sintered iron, temper castings, non‑ferrous metals and hard plastics, making it a versatile choice for workshop and industrial drilling tasks.

How does the fully ground shank benefit drilling accuracy?
A fully ground shank on the MetavCUT Twist Drill ensures reduced runout and more precise centring in the chuck or collet, which translates into cleaner holes and improved repeatability in machining operations.

What are Twist Drills used for?
Twist Drills are mainly used for machining high‑strength materials and large drilling diameters. Their geometry allows straightforward regrinding and they withstand higher loads, making them suitable for deep and heavy‑duty drilling in metals.

Which three drill types exist?
The three main drill types are metal drills, wood drills and stone/concrete drills.

Why are Twist Drills point‑thinned (ausgespitzt)?
Point thinning reduces the cross‑cut at the tip of the Twist Drill, lowering friction and thus reducing required feed forces while improving centring accuracy in the workpiece.

Can a metal Twist Drill be used to drill wood?
A metal Twist Drill can be used in wood, but it will typically offer poorer guidance and a less clean finish than a dedicated wood drill; however, it is easier to resharpen and shows less self‑feeding tendency.

For which drilling depths is the Twist Drill most commonly used?
A through‑hole drilled with a Twist Drill is common practice. For diameters up to 20 mm and drilling depths up to 100 mm, the Twist Drill is the most frequently used tool.

Is HSS or HSSE better?
The common assumption that HSSE steels are always superior to HSS is incorrect. Evaluate working conditions carefully to decide whether HSSE’s higher cost is justified for the intended application.
