4mm Drill-Groove Cutter TiAlN Coated Solid Carbide 3-Flute 57mm Overall, DIN 6527 - TECWERK

Take advantage of a solid carbide construction with TiAlN surface protection and a vibration‑reducing geometry to increase tool life and process stability; order the cutter directly via Metav Werkzeuge or consult their specialists for application‑specific recommendations.

Slot drill DIN 6527 L Type N Ø 4 mm – Solid carbide, TiAlN-coated (TECWERK)

The slot drill DIN 6527 L Type N Ø 4 mm is a long, three‑flute solid‑carbide cutter designed for vibration‑reduced roughing and finishing across steels, cast irons and non‑ferrous alloys

• Solid carbide, TiAlN coating for high wear resistance
• Three‑flute design with centre cutting for plunge cuts
• Neck relief and unequal pitch for vibration reduction
• Shank Ø 6 mm to DIN 6535 HB for secure clamping

Higher productivity through robust cutting geometry

The long‑version cutter combines a solid carbide substrate with a TiAlN coating to deliver extended tool life and consistent wear behaviour during demanding cycles. The three‑flute layout and centre cutting capability permit plunge operations and efficient slotting, while the unequal pitch reduces harmonic excitation. Together these characteristics enable higher metal removal rates with fewer tool changes, improving shop throughput and repeatability.

Reliable surface quality for finishing operations

Thanks to the neck relief (hollow neck) and the 45° protection chamfer, the cutter maintains stability in interrupted and continuous cuts, reducing chatter and leaving predictable surface results. The tool is described as suitable for both roughing and finishing, so one cutter can complete multiple process steps. The relief grind of 3.8 mm and the optimised edge geometry translate into controlled chip formation, which supports consistent part quality in serial production.

Wide material versatility for mixed‑material shops

Engineered for universal use, the tool is very well suited to steel, stainless steel (INOX), cast irons and non‑ferrous metals, as well as special alloys and abrasive materials. The combination of fine‑grain solid carbide and a high‑temperature resistant TiAlN layer makes it particularly resilient when machining harder or mixed batches, enabling fewer tool variants in a versatile production environment.

Secure clamping and machine friendliness

The cylindrical shank to DIN 6535 HB with a 6 mm diameter and h6 tolerance ensures repeatable clamping accuracy in standard collets, while the long overall length (57 mm) and effective length of 12 mm permit access to deeper features. The right‑hand cutting direction and three cutting edges provide balanced cutting forces; the design reduces vibration and supports stable machining even on moderate‑rigidity machines.

FAQ

Is this cutter suitable for plunge cutting or drilling into material?
The slot drill DIN 6527 L Type N Ø 4 mm features a centre cutting geometry, which permits plunge operations and controlled slot entry without prior drilling when using the correct feed strategy.

Which materials can be machined with this TECWERK cutter?
The TECWERK solid‑carbide cutter with TiAlN coating is indicated as very well suited to steel, stainless steel (INOX), cast iron, non‑ferrous metals, special alloys and abrasive materials, offering a universal solution for mixed‑material production.

How does the unequal pitch benefit machining performance?
The unequal pitch reduces synchronous vibrations (chatter) by disrupting harmonic excitation, resulting in improved surface finish and more stable cutting when milling with the long version of this cutter.

What clamping system is required for secure mounting?
The tool has a 6 mm cylindrical shank to DIN 6535 HB with h6 tolerance, making it compatible with standard collets and toolholders that support a 6 mm shank and offer repeatable concentricity.

Can this cutter be used for both roughing and finishing?
Yes. The combination of robust solid carbide substrate, TiAlN coating and optimised geometry is designed for both roughing and finishing, reducing the need to change tools between operations
