Twist Drill — Type N short HSS‑G drill, Ø 4.25 mm, 135° tip, bright finished

The Twist Drill Type N is a short, fully ground HSS‑G drill engineered for precise metalworking tasks in drilling machines and hand drills.

• Short design for higher stability and precision
• HSS‑G ground geometry for clean metal holes
• 135° tip for harder materials like stainless steel
• Fully ground shank for accurate runout
• Conforms to DIN 338 for short twist drills

Precision and strength for demanding metalworking

The Twist Drill from MetavCUT combines a HSS‑G ground geometry with a 135° point to deliver reliable performance when drilling harder metals. Because the flutes and cutting geometry are produced by CNC grinding, the result is sharp cutting lips and a high runout accuracy, which leads to cleaner holes and reduced burr formation. This short version reduces overhang and therefore vibration, so the user benefits from improved centring and longer tool life when paired with adequate cooling.

Stable holes through reduced overhang and robust shank

A shorter overall length means less deflection and better feed control, particularly when working on alloyed and unalloyed steel, cast steel, and non‑ferrous metals. The fully ground shank ensures accurate clamping and minimal eccentricity in the chuck, which supports consistent hole quality. Use in stationary or portable drilling machines profits from the increased stiffness, making the drill a good choice for workshop setups where precision matters.

Who gains most from this compact design

Metalworkers, maintenance technicians and toolroom operators will appreciate the combination of a short flute length and Type N normal spiral for typical metal drilling tasks. The drill was designed to excel where stable, repeatable holes are required rather than for deep through‑holes. For users needing quick, accurate spot drilling and finishing holes in tougher materials, this design reduces rework and improves process reliability.

Practical guidance and material recommendations

To maximise performance, operate the drill with appropriate cutting fluid and moderate speeds for the workpiece material. The 135° point reduces chipping on entry and shortens the start time on hard metals; however, for very soft materials consider a different point geometry. The designation DIN 338 indicates this is a short cylindrical‑shank twist drill series; ground types like this (often marked HSS‑G) are easier to re‑sharpen but can be more brittle than rolled variants, so avoid excessive side loads and use cooling where possible.

FAQ

What is the Twist Drill Type N by MetavCUT used for?
The MetavCUT Twist Drill Type N is mainly used for machining high‑strength materials and larger drill diameters in metalworking. Its short design and ground geometry make it suitable for precise metal drilling tasks where stable, clean holes are required.

Which three drill types exist?
Common drill categories are metal drills, wood drills and masonry/concrete drills, and the MetavCUT Twist Drill Type N belongs to the metal drill group designed for ferrous and non‑ferrous metals.

Why are twist drills pointed?
The point on a twist drill reduces the size of the chisel edge at the tip, lowering friction and therefore the required feed force; this improves centring and reduces the tendency for the drill to wander in the workpiece.

Can a metal twist drill be used for wood?
A metal‑type drill such as the MetavCUT Twist Drill can be used in wood, but guidance and finish are typically inferior compared with dedicated wood drills; however, metal drills are easier to re‑sharpen and have lower self‑feed tendencies.
