20mm T-Slot Cutter Solid Carbide TiAlN Coated 3-Flute Long 104mm OAL, DIN 6527 HB - TECWERK

Take advantage of the combination of solid carbide construction, TiAlN surface treatment and a long neck relief for low‑vibration roughing and finishing. The result is a versatile tool that keeps tool changes and rework to a minimum — order directly via Metav Werkzeuge or request advice from our consultants.

TECWERK slot cutter DIN 6527L – 20 mm, solid carbide, TiAlN, long, 3‑flute

The TECWERK slot cutter DIN 6527L is a long, three‑flute solid carbide cutter designed for low‑vibration slotting and keyway milling in steels, cast materials and non‑ferrous metals.

• Solid carbide (VHM) fine-grain body
• TiAlN coating for heat and wear resistance
• Long design with 3 cutting edges
• Cylindrical shank to DIN 6535 HB, h6 tolerance

Versatile high‑performance machining across a wide material range

With a solid carbide substrate and a TiAlN coating, this long‑reach slot cutter delivers consistent cutting performance in demanding environments. The tool is very well suited to machining steel, stainless steel, cast irons, special alloys and non‑ferrous metals, as well as aluminium alloys containing silicon and abrasive materials. The 20 mm diameter and centre cutting geometry allow plunge cuts as well as peripheral milling, enabling both slotting and light pocketing operations while maintaining dimensional stability.

Geometry and coating engineered for stability and surface quality

The three‑edge configuration with 3 flutes and an unequal helix reduces harmonic excitation and ensures smooth chip evacuation. The tool features a neck relief 19.5 mm that creates clearance for deeper cuts with reduced chance of chatter, while a 0.3 mm 45° chamfer on the cutting edge improves entry behaviour and edge protection. The TiAlN surface increases oxidation resistance and hardness at elevated temperatures, extending tool life and permitting more aggressive feeds and speeds during both roughing and finishing.

Precision shank and long reach for reliable clamping and process repeatability

A cylindrical shank to DIN 6535 HB with h6 tolerance provides secure, concentric clamping in standard tool holders and reduces run‑out related issues. The overall length of 104 mm combined with an effective length of 50 mm supports access to deep slots while the short cutting length of 3 mm concentrates cutting forces on the active edges for controlled metal removal. Right‑hand cutting and a centre‑cut design mean the tool can be integrated into diverse machining strategies without compromise to process reliability.

FAQ

Which materials can be machined with this slot cutter?
The TECWERK slot cutter is very well suited to steel, stainless steel (INOX), cast iron, special alloys and a range of non‑ferrous metals, including aluminium alloys with silicon and other abrasive materials.

Is the tool suitable for plunge cuts and slotting?
Yes, the centre‑cutting geometry permits plunge operations as well as conventional slotting and light pocketing using the TECWERK slot cutter.

What shank specifications ensure secure clamping?
The tool features a cylindrical shank to DIN 6535 HB with h6 tolerance for accurate, concentric clamping in standard tool holders.

How does the TiAlN coating help in production?
The TiAlN coating increases surface hardness and oxidation resistance at elevated temperatures, improving wear resistance and extending the service life of the cutter under harsher cutting conditions.

Which SKU should be referenced when ordering or checking compatibility?
Refer to SKU 2000866295NW when ordering or checking toolholder and process compatibility for this TECWERK slot cutter.
