Twist Drill — Type N, Diameter 3.7 mm, 135° Point Angle, Short Execution, 5% Cobalt-Alloyed, HSS‑E, DIN 338, Fully Ground Shaft (Standard Line) by MetavCUT

The Twist Drill is a short Type N metal drill designed for precise drilling in hard materials with a 135° point angle and a 3.7 mm diameter, ideal for use in a Drilling Machine.

• Short design for greater stability and precision
• HSS‑E with 5% cobalt for higher heat resistance
• Fully ground shaft for excellent runout accuracy
• Conforms to DIN 338 for short twist drills
• Optimised for metal drilling and hard materials

Precision and stability for demanding metalwork

The short Twist Drill design reduces overhang and vibration, which directly improves drilling accuracy and tool life. Because the protruding length is smaller, the drill resists bending and chatter, making it especially suitable for precise holes in steel and other hard materials. This short execution is therefore recommended when high concentricity and repeatable results are required in metalworking tasks.

Material technology that extends performance

Manufactured from HSS‑E and alloyed with 5% cobalt, the drill offers increased hot hardness and wear resistance compared with conventional high-speed steels. The 135° point angle is selected to ease penetration into tough materials and to lower the tendency for the tip to wander. For users unfamiliar with these terms: HSS‑E is a high-speed steel with cobalt additive that maintains hardness at elevated temperatures, while a larger point angle reduces cutting stress on stainless and alloy steels.

Ground geometry for cleaner holes and reliable guidance

This MetavCUT twist drill is fully ground, meaning the flute geometry and cutting edges are produced by CNC grinding rather than roll forming. The result is sharper cutting lips, improved roundness of holes and a better surface finish in the workpiece. For workshop operators this translates into fewer rework steps and less time spent deburring. The Type N spiral (normal helix) provides a balanced chip evacuation for many metal applications.

Conformity and recommended uses

Being manufactured to DIN 338 as a short twist drill, this tool is optimised for drilling in alloyed and unalloyed steel, cast iron, non-ferrous metals and many plastics. The short length and robust material composition make it well suited for stationary and portable Drilling Machines when coolant is applied for deep cuts or harder alloys. For diameters under 6 mm the rolled HSS variant can reduce breakage risk in some settings, but the ground HSS‑E offers superior hole quality for precision work.

FAQ

What is the Twist Drill from MetavCUT best used for?
The MetavCUT Twist Drill is primarily used for metalworking: it is designed to drill high-strength materials and larger diameters where stability and precise guidance are required; its short design and material composition allow it to withstand higher stresses during drilling.

Can the MetavCUT Twist Drill be used in a handheld drill?
The Twist Drill is optimised for Drilling Machines and stationary setups for best results, but it can be used in handheld machines for lighter tasks; however, stable clamping and appropriate feed control are recommended to avoid breakage and to maintain hole quality.

What are Twist Drills used for?
Twist Drills are mainly applied when machining high-strength materials and larger drill diameters. Their shape allows relatively easy regrinding and they withstand higher loads, making them suitable for demanding metal drilling operations.

Which three drill types exist?
The three common drill types are: Metal Drill, Wood Drill, and Stone/Concrete Drill.

Why are Twist Drills sharpened (pointed)?
Pointing reduces the cross-cut at the tip of the Twist Drill, which significantly lowers friction and thus the feed forces required; at the same time the pointed tip centres the drill more accurately in the workpiece.

Can you use a metal drill in wood?
A metal drill can be used in wood, but guidance may be inferior and the hole finish less clean; metal drills are easier to re-sharpen and have less self-feed, so they behave differently compared with wood-specific bits.

For which hole depths is the Twist Drill most commonly used?
Twist Drills are the standard tool for through-holes; they are most commonly used for diameters up to 20 mm and drilling depths up to 100 mm, making them the go-to choice for many machining tasks.
