18mm Straight-Cutting Slot Drill Solid Carbide TiAlN Coating 2-Flute 84mm Overall Length - TECWERK

Benefit from the combination of solid carbide construction, TiAlN high‑temperature resistance and a short, vibration‑reducing geometry for consistent slotting performance; order the TECWERK slot drill directly via Metav Werkzeuge or ask our consultants if needed.

Slot drill DIN 6527 K Type N Ø 18 mm – solid carbide, TiAlN-coated (TECWERK)

A slot drill DIN 6527 K Type N Ø 18 mm engineered for vibration‑reduced slotting, plunge cutting and both roughing and finishing in steels, non‑ferrous metals and abrasive alloys

• Solid carbide, TiAlN coating for heat resistance
• Two flutes for efficient chip evacuation
• Centre‑cutting for plunge and slot milling
• Cylindrical shank to DIN 6535 HB, Ø 18 mm

High‑temperature resistance and broad material compatibility

The short TECWERK slot drill combines a solid carbide body with a TiAlN (titanium aluminium nitride) surface treatment to extend tool life under thermal load and reduce built‑up edge. This combination raises oxidation resistance and preserves the cutting edge during elevated temperatures, which is particularly useful in interrupted cuts and high metal‑removal rates. The tool is rated very well suited for steel, cast iron, Cr‑Ni steels, inox, non‑ferrous metals and special alloys, and also copes with aluminium containing silicon and abrasive materials; the resulting versatility reduces inventory complexity for mixed‑material production runs.

Geometry designed for stable cutting and low vibration

The optimised profile — two flutes, centre‑cutting, a 45° protection chamfer and a dynamic helix — delivers a balance between chip evacuation and cutting stability. The neck relief (freeshank) reduces the contact area where vibration can start, supporting calmer cutting in deep slots and at interrupted entries. The short variant offers improved rigidity compared with longer cutters, making it well suited to operations where chatter must be avoided and a defined slot or pocket face is required. These geometric choices translate into consistent surface finish and repeatable dimensional control when roughing and finishing operations are combined.

Machine compatibility and clamping security for predictable results

Prepared with a cylindrical shank to DIN 6535 HB and a shaft Ø 18 mm with h6 tolerance, the cutter integrates cleanly with standard collet chucks and holder systems suitable for DIN‑compliant tooling. Key dimensions such as overall length 84 mm, effective length 34 mm and relief length 17.5 mm allow process planners to account for tool projection and reach while keeping overhang low. The 2 mm cutting length and right‑hand cutting direction are optimised for short‑slot and plunge operations where precise axial engagement is required. Together, these attributes support predictable tool behaviour, easier balancing of feeds and speeds, and reduced set‑up time on production machines.

FAQ

Which materials can be machined with this slot drill?
The TECWERK slot drill is specified as very well suited for steel, cast iron, Cr‑Ni steels, inox, non‑ferrous metals and special alloys, and it is also suitable for aluminium with silicon content and abrasive materials.

What advantage does the TiAlN coating provide?
The TiAlN coating increases thermal stability and oxidation resistance of the cutting edge, extending tool life in high‑temperature and high‑speed conditions and improving wear resistance on harder or abrasive workpieces.

Is the cutter suitable for plunge cutting?
Yes; the centre‑cutting geometry enables controlled plunge operations and slotting, making the cutter appropriate for combined roughing and finishing tasks that require axial engagement.

Which shank systems are compatible with the tool?
The cutter features a cylindrical shank to DIN 6535 HB with a shaft diameter of 18 mm and h6 tolerance, designed for secure clamping in standard DIN‑compatible collet chucks and holders.

What makes this version 'short' and when is it recommended?
The short variant offers reduced projection and increased rigidity compared with longer cutters; this improves stability and minimises chatter in applications where a compact tool set‑up and vibration‑reduced cutting are priorities.
