Twist Drill Type N by MetavCUT — 6.5 mm, 135° TIN-coated, short HSS-G (DIN 338)

The Twist Drill Type N short HSS-G is a precision metalworking tool designed for use in Drilling Machines, offering high stability and extended tool life for demanding industrial applications.

• Short design for increased stability
• TIN-coated surface extends tool life
• 135° tip for hard materials like stainless steel
• HSS-G fully ground for fast, precise drilling
• Conforms to DIN 338 for reliable metalworking

Increased Stability and Accurate Holes for Metalworking

Shorter tool overhang improves performance in demanding tasks. The short design of this Twist Drill minimises vibration and lateral deflection, delivering consistently accurate holes in alloys and steels. Because the flutes and cutting geometry are ground rather than rolled, the tool achieves high runout precision and cleaner bore edges, which reduces rework and improves component fit. This stability is especially beneficial when machining on portable and stationary Drilling Machines where rigid setup and repeatable hole quality are required.

Coating and Material for Longer Lifetime and Efficiency

A TIN-coated surface combined with HSS-G base material reduces friction and increases wear resistance during metal drilling. The coating lowers heat generation at the cutting edge, so the tool maintains hardness and cutting performance for longer periods under appropriate cooling. For operations involving alloyed and unalloyed steel, cast materials or non-ferrous metals, this combination supports higher productivity and fewer tool changes, which contributes directly to process efficiency on the shopfloor.

Geometry Optimised for Hard Materials and Reduced Feed Forces

The 135° tip angle is tailored for harder workpieces and reduces initial biting forces. A blunter tip compared with standard angles decreases tendency to wander on the workpiece surface and shortens lead-in time when penetrating dense materials. The ground geometry also ensures sharper cutting edges and improved chip evacuation, meaning that operators can achieve deeper, cleaner holes with less applied pressure—important when machining tough steels or sintered components.

Practical Use Cases and Machine Compatibility

Designed in accordance with DIN 338, this short Type N drill is suited for metalworking tasks on both stationary and mobile Drilling Machines. The fully ground shank facilitates precise clamping and concentricity in standard chucks. Typical applications include machining of Tempered Steel, Gusseisen, Bronze, Copper and engineering plastics where controlled chip formation and tool life are priorities. For best results, pairing the tool with appropriate coolant and stable fixturing is recommended to maximise performance and avoid premature wear.

Who Benefits from This Tool and Why

Manufacturers, toolrooms and maintenance professionals who require reproducible hole quality under production conditions will find the Twist Drill advantageous. Its short format makes it ideal for setups where rigidity is limited or where series precision is essential. For users transitioning from rolled HSS drills, the ground geometry delivers noticeable improvements in drilling speed and surface finish while remaining simple to resharpen when required.
