Twist Drill — Drill for Metal (Ø 4.5 mm, 135° Point, Extra Long, Bright Finished, HSS-G, DIN 1869)

The Twist Drill is an Extra Long Drill for Metal designed for deep drilling in Drilling Machines and workshop applications.

• Extra Long design for deep drilling
• Fully Ground shank for high runout accuracy
• HSS-G Material for hard metal performance
• 135° Point Angle optimized for tough alloys
• Bright Finished surface for consistent chip evacuation

Deep reach and faster metal removal for demanding tasks

Engineered as an Extra-Long solution, this Twist Drill delivers extended reach with a Gesamtlänge of 295 mm and a Spiral Length of 200 mm, making it ideal for deep-hole tasks. The HSS-G construction and the special flute geometry enable up to 40 % faster drilling and require 50 % less Anpresskraft compared with conventional HSS tools, which translates to higher productivity on long runs and reduced operator fatigue.

Precision geometry that creates clean, accurate holes

Thanks to the Fully Ground flute geometry and precise Points, the drill achieves very sharp cutting edges and excellent Rundlaufgenauigkeit. The 135° Point Angle is tailored for harder Werkstoffe and shortens Anbohrzeit, while the DIN 1869 specification ensures consistent quality. Because ground tools can be more brittle, stationary operation with coolant is recommended to preserve tool life and hole quality.

Suited materials and professional workshop applications

This Twist Drill is intended for a wide range of Metall applications, including legierten and unlegierten Stahl, Gussstahl, Gusseisen, Sintereisen, Temperguss, Nichteisenmetalle and Hartkunststoff, and is rated for materials up to 1000 N/mm². Workshops, toolrooms and industrial users benefit from the combination of depth capability and cutting performance when working on components that require deep, precise bores.

Handling, sharpening and practical tips for longer service life

For best results mount the drill concentrically in a suitable Chuck of a Drilling Machine and use sufficient coolant during operation. The Ausspitzung (point preparation) reduces Querschneide and lowers Reibkräfte, so lower Vorschubkräfte are sufficient and centering improves. If regrinding is necessary, maintain the 135° geometry to preserve performance; note that ground HSS-G drills are easier to resharpen yet require careful handling to avoid breakage. If unsure whether this tool fits specific requirements, METAV Werkzeuge offers comprehensive technical advice to help select the right solution.

FAQ

What is the MetavCUT Twist Drill used for?
The MetavCUT Twist Drill is primarily applied to the machining of high-strength Werkstoffe and large bore diameters; its form allows relatively easy resharpening and it withstands considerable Belastungen, making it suitable for demanding metalworking tasks.

Which three drill types exist?
There are three common drill categories: Metal Drills, Wood Drills and Stone/Concrete Drills; the MetavCUT Twist Drill belongs to the Metal Drills group and is optimized for metalwork.

Why are Twist Drills pointed?
The point geometry reduces the Querschneide at the Tip of the Twist Drill; by pointing, frictional forces are significantly lowered and smaller Vorschubkräfte are needed while the Tip centers better in the Workpiece.

Can you use metal drills in wood?
A Metal Drill such as the MetavCUT Twist Drill can be used in Wood, but guidance is poorer and the bore finish may be less clean; however, Metal Drills are easier to resharpen and show less self-feed tendency.

For which bore depths is the Twist Drill most commonly used?
A through-hole is commonly executed with a Twist Drill; for diameters up to 20 mm and drill depths up to 100 mm, the Twist Drill is the most frequently used tool, while the extra-long MetavCUT version extends that capability for deeper bores.

Is HSS or HSSE better?
The general belief that HSSE steels are inherently superior to HSS is not universally correct; evaluate working conditions carefully to decide whether the higher investment in HSSE is justified for your specific MetavCUT application.
