Twist Drill (Spiralbohrer) — Short HSS-G Type N, 3.75 mm, 135°, Bright Finished, Fully Ground, DIN 338 — MetavCUT

A Twist Drill (Spiralbohrer) Type N designed for Drilling Machine use, offering a short, rigid HSS-G construction for precise metalworking in hard materials.

• Short design for improved rigidity and accuracy
• HSS-G ground geometry for clean, precise holes
• 135° point angle suited to hard metals and stainless steel
• Fully ground shank for excellent runout accuracy
• Conforms to DIN 338 for short twist drills

Maximum Precision from Ground HSS for Demanding Metalworking

The short HSS-G construction provides a significant increase in Stability compared with longer drills, reducing deflection and enabling more accurate hole placement. This ground variant produces very sharp cutting edges and high Roundness of the bore, which is particularly advantageous when machining alloys and tempered steels. The Type N spiral is the classic metalworking geometry, optimised for consistent chip removal and reliable centring in stationary drilling setups.

Faster, Lower-Force Drilling with Reduced Wear

Engineered to cut with less effort, the ground HSS geometry can deliver up to 40% faster drilling and requires markedly lower feed forces versus conventional HSS products. The 135° Point Angle decreases initial breakthrough stress on the workpiece and is therefore recommended for harder materials such as stainless steel and cast components. This combination reduces tool wear and supports longer life when used with appropriate cooling and feed rates.

Ideal Applications and Target Users

Designed for professional workshops and industrial users, this short Twist Drill excels in precision metal fabrication, maintenance and toolroom tasks. Suitable materials include alloyed and unalloyed steel, cast steel, cast iron, sintered iron, non-ferrous metals and hard plastics. The short overhang makes the tool particularly well suited to tasks requiring dimensional accuracy and minimal runout on drilling machines and dedicated fixtures.

Handling, Regrinding and Machine Compatibility

A ground HSS drill should be used primarily in stationary or rigidly supported drilling machines with appropriate coolant to avoid brittle failure. The fully ground shank ensures consistent chucking stability; regrinding is straightforward for experienced users, preserving cutting geometry. Conformity to DIN 338 ensures predictable dimensions and compatibility with standard toolholders and collets.

FAQ

What is the best use for the MetavCUT Twist Drill (Spiralbohrer) Type N?
The MetavCUT Twist Drill (Spiralbohrer) Type N is primarily used for machining high-strength materials and larger drill diameters; its short, ground design makes it ideal for precise work in alloyed and unalloyed steels, cast components and hard plastics, delivering clean holes and high runout accuracy.

How should the MetavCUT Twist Drill be maintained for longest life?
Regular use with suitable coolant and correct feed rates preserves the sharp HSS-G geometry of the MetavCUT Twist Drill; regrinding should be performed by trained personnel to maintain the original point angle and flute geometry for consistent drilling performance.

For what is a Twist Drill used?
A Twist Drill is mainly applied in the machining of high-strength materials and for larger drill diameters; its geometry is easy to regrind and it withstands significant loads while providing reliable cutting behaviour.

Which three drill types exist?
The three primary drill types are metal drills, wood drills and stone/concrete drills.
