Twist Drill — Type N short, 3.8 mm, 135° point, 5% cobalt-alloyed, HSS‑E, fully ground shank, DIN 338 by MetavCUT

The Twist Drill Type N short is a precision metalworking drill bit designed for stable, high‑accuracy drilling in hard materials using a Drilling Machine.

• Short design for improved stability
• 3.8 mm diameter for precise holes
• 135° point angle for hard materials
• 5% cobalt‑alloyed HSS‑E for heat resistance
• Fully ground shank for high concentricity

Engineered for stable, accurate metal drilling

The short configuration of this Twist Drill delivers a reduced overhang that significantly improves stability and reduces deflection during machining. With a 3.8 mm diameter and a 75 mm overall length including a 43 mm spiral length, the geometry supports precise hole positioning and consistent concentricity. The Type N spiral profile is optimised for metalworking applications, allowing controlled chip evacuation and steady feed rates when used in a suitable Drilling Machine.

Material and wear resistance for demanding tasks

Manufactured from HSS‑E with a 5% cobalt alloy, this short drill bit offers enhanced hot‑hardness and improved wear resistance compared with plain HSS grades. The 135° point angle reduces thrust during entry into hard materials and is particularly effective on stainless steel and other tough alloys. The fully ground flute geometry ensures sharp cutting edges for clean hole walls, while the cobalt content supports longer tool life under elevated temperatures.

Precise manufacturing and conformity to DIN 338

Produced to the DIN 338 specification, the Short Twist Drill features consistent dimensions and dependable interchangeability for industrial use. The fully ground shank and flute finish result in excellent roundness and high runout accuracy, which translates into fewer rejects and faster setup for series production. For tasks requiring repeatability and tight tolerances, this design reduces the need for secondary rework.

Practical applications and user guidance

This drill is intended primarily for Drills for metal operations including alloyed and unalloyed steels, cast iron, non‑ferrous metals and select plastics. Typical uses include maintenance, fabrication and precision engineering where short, stiff drilling tools are preferred. For best results, use appropriate cutting fluid and moderate spindle speeds to exploit the cobalt alloy’s thermal advantages and to minimise risk of premature wear or breakage.

Compatibility and handling recommendations

The fully ground cylindrical shank fits standard chucks of portable and stationary drilling equipment and is especially suited to station‑based Drilling Machines. Because ground HSS drills can be more brittle than rolled variants, avoid excessive vibration and ensure secure clamping; cooling or lubrication is recommended for deeper or continuous drilling cycles. The short length makes bit changes quick and reduces operator fatigue in repetitive tasks.

FAQ

What is the primary use of the Twist Drill MetavCUT Type N short?
The MetavCUT Twist Drill Type N short is used predominantly for metalworking tasks; it is designed to drill through high‑strength materials and larger diameters where a short, rigid tool provides better precision and reduced bending.

Which three drill types are commonly distinguished and where does the Twist Drill fit?
Generally, drill types are classified as metal drills, wood drills and stone/concrete drills. The MetavCUT Twist Drill Type N short belongs to the metal drill category and is optimised for machining metals rather than wood or masonry.

Why are twist drills sometimes point‑sharpened?
Point sharpening reduces the cross‑cut at the tip, lowering friction and thus reducing the required feed forces; a sharper, correctly angled tip also helps centre the drill more reliably in the workpiece.

Can a metal twist drill be used to drill wood?
A metal drill such as the MetavCUT Twist Drill can be used in wood, but guidance and finish may be inferior to a dedicated wood bit; nevertheless, metal drills are easier to regrind and generally exhibit less self‑feed in softer materials.
