Twist Drill Type N — 11 mm · 135° · short · TIN-coated · HSS-G · DIN 338

The Twist Drill Type N is a short, TIN-coated HSS-G drill designed for precision metalworking with a drilling machine.

• Short HSS-G Twist Drill for metalwork
• TIN-coated surface for reduced wear
• 135° tip for hard materials like stainless steel
• Fully ground shank for high precision
• Up to 40% faster drilling, less feed force

Greater Stability and Precision for Tough Materials

Shorter cutting length reduces flex and vibration, which improves hole accuracy when machining metal. The short design of this Twist Drill keeps the overhang minimal, so the cutting forces are better absorbed and the risk of bending is lowered. This makes the tool particularly suitable for demanding tasks in Steel, Cast Iron and other hard materials where consistent concentricity and clean hole geometry are required.

Coating and Material that Extend Tool Life

A TIN-coated surface paired with HSS-G substrate reduces friction and thermal stress during operation. With lower surface wear the drill maintains cutting edge geometry longer, especially under intermittent cooling. For workshops aiming to maximise tool life while maintaining throughput, the combination of Titanium Nitride coating and a ground HSS body delivers measurable benefits in service life and less frequent regrinding.

Designed for Efficient Metal Drilling

Engineered as Type N (normal helix) and conforming to DIN 338, this short Twist Drill is optimised for standard metal-drilling tasks on both stationary and portable drilling machines. The 135° tip geometry shortens the initial penetration time in harder alloys and improves centring for stainless and alloyed steels. Users benefit from faster cycle times and reduced required axial force compared with blunt or generic drills.

Practical Advantages of a Fully Ground Shank

A fully ground shank and flute geometry provide sharp cutting edges and excellent run-out behaviour, producing cleaner holes with less burring. The CNC grinding process yields high concentricity and repeatable performance, which is advantageous when tight tolerances are required. For machining shops that value reproducible quality, this feature supports consistent hole finish and reduced post-processing.

Recommended Applications and User Guidance

This Twist Drill is intended primarily for metalworking: alloyed and unalloyed Steel, Tempered Castings, Cast Iron, Sintered Metals, Copper Alloys and engineering plastics. For best results, use appropriate cooling or lubrication to further reduce temperature and wear. When regrinding or sharpening is necessary, take into account the ground geometry to maintain the original tip angle and helix profile for reliable performance.

FAQ

What is the primary use of a Twist Drill?
The Twist Drill MetavCUT Type N is mainly applied for machining high-strength materials and larger drill diameters; its geometry and coating make it suitable for demanding metal-drilling tasks where longevity and edge retention are important.

Which three drill types exist?
Typical categories are Metal drills, Wood drills and Masonry/Concrete drills; the Twist Drill MetavCUT Type N belongs to the Metal drills group and is optimised for ferrous and non-ferrous metals.

Why are Twist Drills point-split (sharpened)?
Point-splitting reduces the cross-edge at the tip, which significantly lowers friction and the required feed force; as a result the MetavCUT Twist Drill centres more reliably and penetrates the workpiece with less push effort.

Can a metal Twist Drill be used to drill wood?
A Metal drill such as the Twist Drill MetavCUT Type N can be used in wood, but guidance and hole quality are worse than with dedicated wood drills; however, metal drills are easier to resharpen and show reduced self-feeding.

For which drilling depths is the Twist Drill most used?
A solid through-hole is typically produced with a Twist Drill. For diameters up to 20 mm and drilling depths up to 100 mm, the Twist Drill remains the most frequently used tool in workshop practice.

Is HSS or HSSE better?
The general assumption that HSSE is always superior to HSS is not universally correct. Evaluate the actual working conditions to determine whether the higher acquisition cost of HSSE is justified for the intended application.
