MetavCUT Twist Drill – Type N short, 7.7 mm, HSS‑E, 135°, 5% cobalt‑alloyed, fully ground, DIN 338

The Twist Drill from MetavCUT is a short Type N drill designed for precision metalworking and optimized for drilling machines and hand drills.

• Short design for increased stability and precision
• 7.7 mm Diameter for accurate through‑holes
• 135° Point angle for hard materials like stainless steel
• Fully ground shank for high runout accuracy
• HSS‑E with 5% cobalt for enhanced wear resistance

Precision and stability for demanding metalwork

The short Twist Drill construction reduces the protruding length from the chuck, resulting in markedly improved Stability and less tendency to bend under load. This makes the tool particularly suitable for precise operations and for drilling in hard Metals where deflection would compromise hole quality. With a 135° Point Angle, the cutting action engages smoothly on tough surfaces, shortening dwell on entry and improving centring on stainless steel and alloyed steels.

Material composition and durability benefits

Manufactured from HSS‑E with 5% cobalt alloying, this short Type N drill offers improved Heat Resistance and edge life compared with standard HSS. The cobalt content supports higher cutting temperatures and helps maintain sharpness when machining alloyed or high‑strength Steels. The fully ground flute geometry provides very sharp cutting edges and high roundness, which delivers clean holes and consistent tool life under appropriate coolant and machine conditions.

Designed for efficient workshop use

By combining a short overall length with a roll‑free, fully ground shaft and compliance with DIN 338, the drill delivers reproducible hole quality on stationary and portable machines alike. The reduced overhang lowers vibration, enabling higher feed rates and improved surface finish for through‑holes. For routine metal drilling tasks the short HSS‑E Twist Drill allows operators to maintain productivity without sacrificing precision.

Recommended applications and user guidance

This Twist Drill is optimised for drilling in Alloyed and Unalloyed Steel, Cast Iron, Non‑Ferrous Metals and Plastics when high precision is required. For best results, use appropriate cutting fluid and secure workholding; short drills perform best in guided or rigid setups. If drilling in softer woods, be aware that metal drills can work but may show inferior guidance and finish compared with purpose wood drills. For holes up to moderate depths, the short geometry reduces breakage risk in small diameters and improves repeatability.

FAQ

What is the MetavCUT Twist Drill Type N primarily used for?
The MetavCUT Twist Drill Type N is primarily used for machining high‑strength and alloyed Metals; it excels in through‑holes for metalworking thanks to its short design and HSS‑E composition, which combined allow reliable drilling in demanding materials.

Can the MetavCUT Twist Drill be used for wood?
The MetavCUT Twist Drill (Type N) can be used in Wood, but as a Metal drill it offers less guidance and a rougher finish than a dedicated Wood drill; it is easier to re‑sharpen and shows less self‑pulling action compared with specialised wood bits.

For what is a Twist Drill used?
A Twist Drill is mainly applied to the machining of high‑strength workpieces and larger drill diameters; its shape allows straightforward re‑grinding and it withstands greater loads, making it suitable for drilling Metal and other tough materials.

Which three drill types exist?
The main drill categories are Metal drill, Wood drill and Stone/Concrete drill, and the MetavCUT Twist Drill belongs to the Metal drill group designed for steels and non‑ferrous Metals.

Why are Twist Drills pointed?
The point profile reduces the secondary cutting edge at the tip, lowering friction and thus decreasing required feed forces; this sharpening also improves centring accuracy when the MetavCUT Twist Drill is used in the workpiece.

For which drilling depths is the Twist Drill most used?
A solid bore is typically executed with a Twist Drill; for diameters up to about 20 mm and depths up to 100 mm, the Twist Drill is the most commonly used tool thanks to its versatile geometry and reliability.

What is better, HSS or HSSE?
The general assumption that HSSE steels are always superior to HSS is not correct; when deciding for the MetavCUT Twist Drill in HSS‑E, assess whether the working conditions justify the higher cost of HSSE, as performance gains depend on the specific application and material.
