Twist Drill — short Type N, 7.3 mm, 135°, HSS‑G, DIN 338, bright finished

The Twist Drill is a short Type N metalworking drill designed for precision work in hard materials, with a 7.3 mm Diameter and a 135° Point Angle suitable for Drilling Machines.

• Short Design for High Stability and Precision
• HSS-G Material for Clean, Accurate Holes
• 135° Point Angle for Hard Materials
• Fully Ground Shank for High Runout Accuracy
• DIN 338 Standard for Short Twist Drills

Precision and Stability for demanding metalwork

The short geometry with a 69 mm Spiral Length and 109 mm Overall Length reduces overhang and vibration, resulting in significantly improved stability and straighter holes. The reduced projection from the chuck lowers the tendency to bend under load, which is particularly advantageous when machining tough alloys or performing series production where repeatable results matter. The compact form factor aids guided drilling in jigs and setups requiring minimal runout.

Faster cutting and lower feed force through HSS‑G grind

Manufactured from HSS‑G, the cutting Edges are produced by CNC grinding, delivering very sharp lips and excellent concentricity. This fully ground design enables up to 40% faster drilling and requires about 50% less feed force compared with conventional HSS drills, improving cycle times and reducing operator fatigue. Note: ground HSS can be more brittle than rolled types, so cooling and correct clamping are recommended to avoid breakage.

Optimised for metal — material range and machine use

Designed as a Type N (normal spiral), this short Twist Drill is targeted at metalworking: alloyed and unalloyed steels, Cast Steel, Cast Iron, Sintered Iron, Tempered Cast Components, Non‑Ferrous Metals and hard Plastics. Conforming to DIN 338 for short twist drills with cylindrical shank, it is suitable for use on rotating stationary or mobile machine tools and for application in drilling machines where precision and durability are required.

Handling tips for reliable, long service life

A fully ground shank ensures low runout and precise clamping; however, to maximise lifetime and hole quality, apply appropriate cutting fluid when machining hard steels and reduce feed if chatter occurs. The 135° Point Angle shortens initial penetration time in harder materials but benefits from steady spindle speed and proper coolant. For best results, use correct chucking, avoid excessive overhang and inspect for wear frequently.

FAQ

What is the MetavCUT Twist Drill Type N used for?
The MetavCUT Twist Drill Type N is primarily used for machining high‑strength materials and larger diameters in metalworking; its short design and robust geometry make it especially suitable for precise drilling in hard steels and similar workpieces.

Which three drill types exist?
Typical distinctions are: Metal drills (for steel and alloys), Wood drills (for timber and wood composites), and Stone/Concrete drills (for masonry and concrete).

Why are Twist Drills pointed?
Pointing reduces the cross‑cut at the tip, lowering friction and therefore the required feed forces; a sharpened tip also improves centring in the workpiece and leads to cleaner, more accurate holes.

Can a metal Twist Drill be used in wood?
A metal Twist Drill can be used in wood but will typically provide less guidance and a rougher finish than a dedicated Wood drill; however, metal drills are easier to regrind and exhibit lower self‑feed tendencies.

For which drilling depths is the Twist Drill most used?
A solid hole is commonly produced with a Twist Drill; for diameters up to around 20 mm and drilling depths up to about 100 mm, the Twist Drill is the most frequently used tool.

Is HSS or HSSE better?
The general belief that HSSE is categorically superior to HSS is not always correct; choose based on actual working conditions and whether the performance advantages justify the higher cost.
