8mm Drill Groove Cutter DIN 327D Type N HSS-Co8 TiCN Coated 2-Flute Short 17mm Effective Length, 10mm Shank - TECWERK

Take advantage of the HSS‑Co8 substrate combined with a TiCN coating and a short, rigid two‑flute geometry to mill precise keyways with reduced tool changes and consistent surface quality. Order the cutter directly via Metav Werkzeuge or consult our specialists for process integration.

Slot milling cutter DIN 327D Type N — 8 mm, HSS‑Co8 with TiCN (TECWERK)

The Slot milling cutter DIN 327D Type N is a short, two‑flute centre‑cutting tool designed for milling narrow, form‑accurate keyways and tight fits in steel, stainless steel and cast iron.

• HSS‑Co8 base for extended life
• TiCN coating for enhanced wear resistance
• Weldon shank 10 mm for secure clamping
• Designed for precision keyways and tight fits

Precision for narrow keyways and tight fits

The short two‑flute design, compliant with DIN 327 D, provides high rigidity during slotting operations, so form accuracy is consistently maintained. With an 8 mm working diameter and centre cutting capability, the tool enables plunge‑milling and slot entry without pre‑drilling in many setups. This geometry reduces radial runout and vibration, which translates into fewer rejects and lower rework rates when producing keyways or narrow seating surfaces.

Durable cutting performance through material and coating

A HSS‑Co8 substrate paired with a TiCN surface layer offers a balance of toughness and heat resistance that lengthens tool life under intermittent and continuous cutting conditions. The TiCN coating reduces built‑up edge and improves wear behaviour when machining steels up to approximately 1000 N/mm², helping to maintain consistent dimensional results over longer tool lifetimes. The result is fewer tool changes and greater uptime for repetitive production runs.

Stable clamping and reliable machining results

The cutter features a Weldon shank with a 10 mm diameter and a drive flat, ensuring secure clamping in standard tool holders and reducing slippage under load. The short overall length improves rigidity, while the measured relief length (freeschliff 7.5 mm) and right‑hand cutting direction provide stable chip evacuation and predictable surface finish. For production environments where process stability matters, this configuration supports repeatable, high‑quality outcomes.

Applications, material suitability and process fit

Optimised for tight, form‑critical operations, the tool is particularly well suited to stainless steel and cast iron, and offers very good performance in a broad range of steels. Non‑ferrous materials and special alloys are conditionally suitable depending on cutting parameters. Typical uses include precision keyways, deep feather‑key slots and narrow grooving where DIN conformity and repeatability are required. Integration into automated or manual milling stations is straightforward thanks to the standard shank and centre‑cutting capability.

FAQ

Which materials can be machined with this cutter?
The slot milling cutter DIN 327D Type N (TECWERK) is very well suited for stainless steel and cast iron, performs very well in a wide range of steels and is conditionally suitable for non‑ferrous metals and special alloys.

Is the cutter able to perform plunge entries?
Yes, the tool is centre cutting, which allows plunge‑milling into the workpiece and simplifies slot starts without the need for a pre‑drilled hole in many cases.

What clamping interface is required?
A secure Weldon‑style clamping system or a holder accepting a 10 mm cylindrical shank with a drive flat is recommended to prevent slippage and to maintain process stability.

For which applications is the short version particularly advantageous?
The short geometry increases rigidity and is ideal for machining keyways, narrow grooves and form‑critical fits where minimal deflection and repeatable accuracy are essential.

How does the TiCN coating affect performance?
The TiCN coating improves wear resistance and reduces built‑up edge, extending tool life and helping to preserve dimensional tolerances over longer production runs.
