Twist Drill — Type N, 6.5 mm, 135° tip, short, 5% cobalt-alloyed, HSS‑E, DIN 338

The Twist Drill Type N is a short HSS‑E metalworking drill designed for stable, precise holes in hard materials when used with a Drilling Machine.

• Short construction for increased stability
• 6.5 mm diameter for standard metalwork
• 135° tip for clean penetration in hard steels
• 5% cobalt‑alloyed HSS‑E for enhanced wear resistance
• Fully ground shank for high concentricity

Durable alloy and compact design for demanding metalwork

The HSS‑E composition with 5% cobalt gives this short twist drill exceptional heat resistance and wear stability when machining tough alloys. Because the design is short, the tool exhibits reduced overhang and less flexing, which directly improves hole accuracy and tool life under heavy cutting loads. This makes the drill particularly suitable for precision tasks such as locating holes in jigs and producing repeatable diameters in alloyed and unalloyed steel.

Geometry and finish that improve hole quality and centring

A fully ground flute geometry yields very sharp cutting edges and excellent concentricity; the typical result is cleaner chips and reduced burr formation. The 135° tip angle reduces thrust and improves entry in hard materials such as stainless steel, shortening the initial contact phase and helping to avoid wandering. As a Type N normal‑spiral twist drill, it balances chip evacuation and cutting stability for general metalworking.

Recommended applications and suitable materials

This short Twist Drill is engineered for use in metalworking: it performs well on alloyed and unalloyed steel, cast iron, non‑ferrous metals and many plastics. The compact length is an asset when working with hand or bench drilling machines where rigidity is crucial. Note that Type N geometry is not optimised for very soft woods; for woodworking, specialist drills provide better guidance and surface finish.

Handling, cooling and reconditioning advice for longer life

To maintain performance, use appropriate cutting speeds and a cutting fluid when machining steels; cooling reduces tool wear and the risk of tempering the cutting edge. Because the drill is manufactured ground, it can be resharpened by a skilled operator to restore the cutting lip and prolong service life. Observing correct feed and speed settings for the material ensures reliable hole quality and minimises breakage risk.

FAQ

What is the Twist Drill Type N best used for?
The MetavCUT Twist Drill Type N is primarily used for metalworking; it excels when drilling alloyed and unalloyed steels, cast iron and other hard materials, offering good general performance on rotating drilling machines.

Can the MetavCUT Twist Drill be used in a hand drilling machine?
Yes, the short design of the MetavCUT Twist Drill makes it especially stable in hand and bench Drilling Machines, reducing the tendency to bend and improving hole accuracy when correct speeds and cooling are applied.

What are Twist Drills used for?
Twist Drills are mainly applied when machining high‑strength materials and larger diameters. Their form allows relatively simple resharpening and they withstand higher loads, making them suitable for robust metalworking tasks.

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