8mm Slot Drill Solid Carbide TiAlN-Coated 3-Flute Short 58mm Overall, DIN 6527 - TECWERK

Take advantage of the combination of solid carbide construction, TiAlN high‑temperature coating and a vibration‑reducing geometry to ensure consistent performance in both roughing and finishing operations; order the cutter via Metav Werkzeuge or ask their specialists for application advice.

TECWERK Slot Drill DIN 6527K Type N, 8 mm — Solid Carbide (VHM), TiAlN‑coated, 3‑flute, short

A TECWERK slot drill DIN 6527K Type N, 8 mm engineered for low‑vibration milling and reliable material versatility across steels, cast irons and non‑ferrous alloys

• Solid carbide VHM for high rigidity
• TiAlN coating for thermal resistance
• 3‑flute geometry for smooth cutting
• Short design with 45° protection chamfer

Durable carbide and high‑temperature resistance for longer tool life

The cutter is manufactured from solid carbide, fine‑grain grade, giving high rigidity and consistent edge retention under load. The TiAlN coating increases heat resistance and reduces adhesive wear at elevated cutting temperatures, which extends service intervals and maintains surface quality. With this combination, the tool supports higher cutting speeds where appropriate and preserves edge geometry during intermittent or demanding cuts, helping to keep production reliable and predictable.

Stable cutting performance for both roughing and finishing

A 3‑flute geometry with a centre cut and an unequal helix minimises harmonics and reduces chatter, resulting in a low‑vibration machining process. This makes the cutter suitable for both roughing and finishing operations in a broad range of materials — including steels, cast irons, stainless and non‑ferrous alloys — where dimensional stability and surface finish are important. The right‑hand cutting direction and newly developed flute geometry enable efficient chip evacuation and consistent feed rates.

Precise shank and protective geometry for secure clamping

The tool features a cylindrical shank DIN 6535 HB with Ø 8 mm and h6 tolerance for reliable clamping and concentricity in standard toolholders. A 45° protection chamfer (0.12 mm) at the cutting edge enhances strength at the margin and reduces edge chipping during plunge or interrupted cuts. With an effective length 20 mm, overall length 58 mm and a cutting length 3 mm, the geometry is optimised for short, stiff set‑ups where tool rigidity and positional accuracy determine machining quality.

Practical economy through reduced downtime and universal use

The combination of robust substrate and thermal coating reduces flank wear and extends tool life, lowering total cost per part in repetitive production. The design is universally applicable to a wide material spectrum — from aluminium alloys with silicon content to Cr‑Ni steels and various cast irons — so fewer tool changes are necessary across mixed production runs. The neck relief and controlled free relief of 7.7 mm support vibration damping, improving reproducibility and reducing rework rates for component batches.

FAQ

Which materials are suitable for this cutter?
The TECWERK slot drill (slot cutter) with SKU 2000866247NW is very well suited to steels, stainless steels, cast irons, non‑ferrous metals and special alloys, making it a universal choice for mixed‑material workshops.

How does the TiAlN coating benefit machining?
TiAlN provides thermal resistance and reduced adhesion at the cutting edge, which improves tool life and stability during higher temperature cuts when machining tougher materials.

Is the tool suitable for both roughing and finishing?
Yes — the 3‑flute geometry and engineered helix reduce vibration and support both roughing and finishing operations while maintaining surface quality.

What shank and clamping specifications apply?
The cutter has a cylindrical shank to DIN 6535 HB with Ø 8 mm and h6 tolerance, designed for secure clamping in standard holders and high concentricity.

Can it handle interrupted cuts or plunge operations?
The centre cut and the 45° protection chamfer increase edge robustness and support limited plunge capability as well as improved behaviour in interrupted cuts.
