TECWERK long 3‑flute slot drill DIN 6527 L — 3 mm, VHM, TiAlN

The TECWERK long 3‑flute slot drill DIN 6527 L is a solid‑carbide slotting cutter with TiAlN coating, designed for universal milling tasks where vibration control and clean centre cutting are required.

*Solid carbide (VHM) with TiAlN coating
*Long 3‑flute geometry with centre cut
*For steels, cast iron and non‑ferrous metals
*Cylindrical shank DIN 6535 HB, Ø 6 mm

Consistent tool life through material and coating

The combination of VHM (solid carbide) substrate and TiAlN coating provides strong wear resistance and thermal stability, which translates into extended tool life under demanding cycles. The TiAlN layer reduces adhesion and oxidation at elevated temperatures, making the cutter especially suited to intermittent slotting and applications with elevated heat generation. For everyday workshop planning this means fewer tool changes and more predictable production runs when machining steels, stainless steels and non‑ferrous alloys.

Geometry engineered for efficient chip control and surface finish

A three‑flute layout with centre cut enables stable plunging and precise slot formation while the unequal helix minimises harmonic vibration. The long version and neck relief produce a vibration‑reduced cutting action, improving surface quality during both roughing and finishing passes. The 45° protection chamfer and unequal pitch assist in chip evacuation and reduce edge build‑up, delivering consistent component surfaces even in serial production.

Workshop compatibility and secure clamping for repeatable results

Designed with a cylindrical shank according to DIN 6535 HB and a shank diameter of Ø 6 mm, the cutter fits common toolholders and collets with h6 tolerance for precise seating. Key dimensions — overall length 57 mm, effective length 10 mm and cutting length 3 mm — ensure predictable reach and stability in fixtures with limited clearance. The small protection chamfer (0.07 mm) and defined free grind 2.9 mm support safe entry and reduce the risk of burrs, which benefits downstream processing and assembly.

Practical use cases and process recommendations

This long slotting cutter is engineered as a universal solution for machining a wide range of materials: carbon and alloy steels, cast irons (grey and malleable), Cr‑Ni grades, non‑ferrous metals and aluminium alloys with silicon content, plus abrasive and special alloys. The tool’s centre‑cutting capability permits controlled plunging where required, while the TiAlN surface assists in dry or reduced‑coolant strategies by protecting against thermal wear. For best results, select cutting parameters that favour steady chip removal and take advantage of the cutter’s vibration‑damping geometry for improved cycle times and reduced rework.

FAQ

Can this cutter plunge for slot starts or centre holes?
The TECWERK long 3‑flute slot drill is centre‑cutting, so it permits controlled plunging for slot starts and pocket entries; its geometry supports safe axial engagement.

Which materials are best machined with this cutter?
This slotting cutter is suitable for a broad range: carbon and alloy steels, cast irons, Cr‑Ni steels, non‑ferrous metals and aluminium alloys with silicon content, as stated in the technical features.

Is the tool suitable for finishing as well as roughing?
Yes, the tool’s geometry and TiAlN coating make it suitable for both roughing and finishing passes, delivering improved surface quality and tool life.

What clamping system is recommended for optimal accuracy?
Use a collet or holder that conforms to the shank specification DIN 6535 HB with h6 tolerance to secure repeatable concentricity and minimise run‑out.

Does the TiAlN coating allow for dry machining?
The TiAlN coating enhances thermal resistance and reduces adhesion, which supports dry or reduced‑coolant machining in many applications; final strategy depends on material and cycle demands.
