Twist Drill — Type N, 9.9 mm, 135° tip, short, bright finished, HSS‑G, DIN 338 (MetavCUT)

The Twist Drill Type N is a short HSS‑G drill for precision metal drilling, designed for use in hand and machine drilling applications.

• Short design for improved stability
• 135° tip for hard materials
• HSS‑G fully ground for precise holes
• Conforms to DIN 338 for metalworking

Precision and performance for demanding metalwork

Designed for accurate metal drilling, this HSS‑G short Twist Drill delivers consistently clean holes with high roundness. The fully ground geometry produces very sharp cutting edges and excellent runout characteristics, which reduces burr formation and improves hole quality. For users seeking reliable results in alloyed and unalloyed steels, the combination of Type N spiral and a 135° point angle supports controlled penetration and reduces lateral wandering during the initial drill entry.

Short length for stability and faster operation

Because the bit has a reduced protruding length, the short design significantly increases rigidity and lowers the tendency to bend under load. This leads to measurable workflow benefits: the grinded HSS geometry enables drilling up to 40% faster while requiring 50% less feed force compared with conventional HSS variants. Contractors and workshop technicians working on small setups or clamped workpieces profit from improved precision and less chatter when using a compact, robust drill of this design.

Geometry and materials optimised for hard materials

The 135° tip angle is chosen specifically to assist drilling into harder materials such as stainless steel and tempered components; a larger point angle shortens initial bite time while maintaining tool life. The designation DIN 338 classifies this short Twist Drill with a cylindrical shank and describes the ground manufacturing process; grinding (HSS‑G) creates sharp cutting lips but can make the tool more brittle, so coolant and steady machine setup are advisable to avoid premature breakage.

Who benefits and practical usage advice

This Twist Drill is targeted at professional users and advanced hobbyists needing reliable metal drilling — especially for precision work on lathe‑mounted or stationary drilling machines and well‑supported handheld drilling operations. The fully ground shank ensures good chucking accuracy; for best results, secure the workpiece, use appropriate cutting fluid and moderate feed, and avoid excessive overhang. MetavCUT’s short series is particularly suitable when stability and accuracy are priorities over reach.

FAQ

What are Twist Drills used for and which materials suit them best?
The MetavCUT Twist Drill Type N is primarily used for drilling metal; it is especially effective on alloyed and unalloyed steels, cast materials and non‑ferrous metals. Its geometry and 135° point make it suitable for harder workpieces where accurate centring and reduced walking are required.

Which three drill types are commonly distinguished?
In general practice three main categories are identified: metal drills, wood drills and stone/concrete drills. The MetavCUT Twist Drill Type N belongs to the metal drill group and is optimised for machining metallic materials.

Can the MetavCUT Twist Drill be used in a handheld drill or only in machine tools?
The short design of the MetavCUT Twist Drill Type N improves rigidity and makes it suitable for both well‑supported handheld drilling and stationary machine tools; however, optimum precision is achieved in clamped or machine setups with appropriate cooling.

Why is the tip of a Twist Drill ground to a specific angle?
The 135° tip on the MetavCUT Twist Drill reduces initial cutting forces and improves centring in hard materials; grinding the tip also reduces the cross‑cut width, lowering friction and the required feed, which helps achieve cleaner holes with less tool wear.
