TECWERK slot drill DIN 6527L Type N Ø16 mm (solid carbide, TiAlN, 3‑flute)

A TECWERK slot drill DIN 6527L Type N engineered for vibration‑reduced roughing and finishing across steels, cast components and non‑ferrous alloys

• Solid carbide (VHM) for high stiffness
• TiAlN coating for elevated heat resistance
• 3‑flute geometry for smooth chip flow
• Cylindrical shank DIN 6535 HB, Ø16 mm

Longer tool life through coating and substrate synergy

The combination of a solid‑carbide substrate with a TiAlN coating provides a clear technical advantage where thermal stability and abrasion resistance matter. The coating increases oxidation resistance at elevated temperatures, which reduces flank wear under extended engagement; the carbide core maintains rigidity for stable cutting. This means fewer interruptions for tool changes and a more consistent production rhythm, particularly when machining steel, stainless alloys and abrasive materials where temperature and abrasion accelerate tool degradation.

Geometry designed to cut vibration and improve surface finish

The cutter’s 3‑flute geometry together with an unequal helix pitch reduces harmonic vibration and promotes even chip evacuation, enabling both material removal and fine finishing in one tool when the process is set up accordingly. The centre‑cutting design allows controlled plunging and contour entry, while the 45° protection chamfer (0.2 mm) protects the cutting edge during entry and exit. These features lower the risk of chatter and lead to improved dimensional consistency on workpieces with interrupted or thin‑wall sections.

Secure clamping, predictable runout and versatile dimensions

With a DIN 6535 HB cylindrical shank and Ø16 mm diameter held to h6 tolerance, the tool offers reliable clamping repeatability in standard holders. The overall length of 92 mm and an effective length of 40 mm balance accessibility with rigidity, while the free relief of 15.5 mm reduces contact at the neck for applications requiring deeper reach. These dimensional choices translate into predictable runout performance and straightforward integration into existing tool‑holding systems, supporting stable results across batch sizes.

Practical machining notes for mixed‑material workplaces

The tool is optimised for a broad material spectrum — including steel, cast iron variants, Cr‑Ni steels, non‑ferrous metals and aluminium alloys containing silicon — making it well suited to mixed‑job shops and component repair lines. Employ conservative radial engagement and let the cutter’s geometry handle axial load for improved surface integrity. For tough or abrasive alloys, the TiAlN surface treatment helps maintain cutting edges longer; for softer non‑ferrous workpieces the same geometry delivers fast chip evacuation and reduced built‑up edge. These adjustments support efficient throughput without sacrificing finish quality.

FAQ

What materials is this cutter suitable for?
The TECWERK slot drill is specified for a wide range of materials, including steel, cast iron, Cr‑Ni steels, non‑ferrous metals and aluminium alloys with silicon, offering very good suitability for each listed group.

Can this tool be used for plunging operations?
Yes. The centre‑cutting geometry and reinforced chamfer of the TECWERK slot drill permit controlled plunge entries in suitable tool paths.

How does the TiAlN coating benefit machining performance?
The TiAlN coating on this solid‑carbide cutter raises thermal stability and abrasion resistance, which reduces wear during extended engagement and contributes to longer tool life.

Is the shank compatible with common holders?
The cutter has a cylindrical shank to DIN 6535 HB with an h6 tolerance at Ø16 mm, providing secure clamping and predictable runout in standard tool holders.

What makes the geometry vibration‑reducing?
An unequal helix pitch combined with a 3‑flute layout reduces harmonics and promotes even chip flow, which helps to minimise chatter and improve surface finish during both roughing and finishing.
