Twist Drill Type N — 4.5 mm, 135° point angle, short execution, 5% cobalt-alloyed, HSS‑E, DIN 338

The Twist Drill Type N is a short HSS‑E metalworking bit designed for stable, precise drilling in hard materials with a 135° Point Angle and a fully ground shank for high concentricity.

• Short Twist Drill 4.5 mm for precise metalwork
• 135° Point Angle for hard materials like stainless steel
• 5% cobalt-alloyed HSS‑E for higher heat resistance
• Fully ground shank for excellent concentricity and finish
• Conforms to DIN 338 for short Twist Drills

Designed for precision in metalworking and stable drilling

Short design delivers a tangible benefit: reduced overhang means less deflection and improved accuracy when working with tough materials. The compact geometry of this short Twist Drill supports higher rigidity, so holes remain rounder and positional tolerances are easier to achieve. This is particularly relevant when machining alloyed or unalloyed Steel, Cast Iron and other Metals where tool chatter or bending would otherwise impair results. The result is a reliable Tool that helps maintain Process stability in both bench and machine applications.

Robust Material and geometry for demanding applications

Manufactured from HSS‑E with 5% cobalt-alloyed composition, the bit resists softening under elevated temperatures and keeps cutting edges sharper for longer life. The 135° Point Angle reduces entry forces on hard materials and improves centring on tougher Surfaces such as Stainless Steel. Being a Type N normal spiral, the geometry balances chip evacuation and edge strength—explainable: HSS‑E adds hot hardness, cobalt increases wear resistance; together they extend tool life under intermittent or high-load drilling.

Machine compatibility and standards for reproducible results

Designed according to DIN 338 for short Twist Drills, this Tool fits standard chuck systems and is intended for use in a drilling machine or hand drilling Machine where increased stiffness is required. The fully ground Shank ensures superior concentricity and runout characteristics, which supports precision fixtures and measured machining. For operators, this means fewer rejections and easier post-process handling when producing repeatable holes in metal components.

Practical guidance, target users and safe operation

Workshop professionals, maintenance technicians and toolroom users benefit most from this short Twist Drill due to its stability and suitability for harder metals. Use moderate cutting speeds, appropriate coolant for metalworking, and firm clamping to exploit the Drill’s advantages; avoid excessive overhang despite the short form. The fully ground flute geometry is explained by its manufacturing: grinding produces very sharp cutting edges and high Roundness, but requires careful handling to avoid brittle fractures—especially at very small diameters or under unsupported conditions.

FAQ

What is the best use for the Twist Drill Type N from MetavCUT?
The MetavCUT Twist Drill Type N is primarily intended for drilling Metal; it excels in machining high-strength and alloyed steels thanks to its short design, which increases stability and reduces bending during operation.

Can the MetavCUT Twist Drill Type N be used with a hand drilling machine?
Yes, the MetavCUT Twist Drill Type N can be used in a hand drilling Machine, but optimal results are achieved with a well-secured workpiece and steady feed to minimise stress on the short, fully ground flute geometry.

For what is a Twist Drill used?
A Twist Drill is mainly applied when working on high‑strength materials and large diameters; its form is easy to regrind and withstands higher loads while remaining suitable for precision metal drilling.

Which three drill types exist?
The three main drill types are Metal drills, Wood drills and Stone/Concrete drills; the MetavCUT Twist Drill Type N belongs to the Metal drill category.

Why are Twist Drills pointed?
Pointing the Twist Drill reduces the secondary cutting edge at the tip, which lowers friction and the required feed forces while improving centring of the Drill in the Workpiece.

Can a Twist Drill be used to drill wood?
A Metal drill such as the MetavCUT Twist Drill Type N can be used in Wood, but guidance and hole finish are inferior compared with dedicated Wood drills; however, Metal drills are easier to regrind and have less self‑feeding tendency.

At which drilling depths is the Twist Drill most used?
A drilling operation into solid material is typically performed with a Twist Drill; for diameters up to 20 mm and drilling depths up to 100 mm, the Twist Drill is the most commonly used tool.
