Keyway cutter DIN 327 Type N — 18 mm, HSS‑Co8, 3‑flute, Weldon — TECWERK

The Keyway cutter DIN 327 Type N is a short, three‑flute milling cutter designed for precise keyway and slot machining in steel and cast iron, with a Weldon shank for reliable clamping.

• HSS‑Co8 construction for high wear resistance
• 3‑flute geometry for precise keyway cutting
• Weldon shank Ø16 mm for secure clamping
• Suitable for steel and cast iron up to ~800 N/mm²

Robust cutting performance for repetitive keyway work

Constructed from HSS‑Co8, this short keyseat cutter delivers a balance of toughness and hardness that extends tool life under intermittent loads. Compliance with DIN 327 ensures geometries suited to standard keyway profiles, while the three cutting edges provide steady material removal and reduced vibration. For uncoated tools the capability extends to materials with tensile strengths around 800 N/mm²; with appropriate coatings the useful range increases to about 1000 N/mm², enabling application across many general workshop and light industrial tasks.

Secure clamping and rigid setup reduce runout

The Weldon shank with Ø16 mm diameter and a compact overall length of 79 mm promotes high rigidity at the cutter tip. The short version with an effective length of 29 mm and a free relief of 15 mm limits overhang, which in turn reduces deflection and produces cleaner slot walls. These characteristics support faster cycle times with consistent slot dimensions and minimise the need for corrective finishing operations.

Intended use and material suitability explained

Designed primarily for keyway milling, face and peripheral operations, the cutter excels on cast iron and low‑to‑medium strength steel, offering very good performance on these substrates. Performance on stainless steel and non‑ferrous metals is classed as conditional; for those materials, optimising feeds, speeds and, where appropriate, using coated variants will improve results. The tool’s right‑hand cutting geometry supports conventional milling setups and predictable chip formation.

Practical handling and service guidance for continuous productivity

The short geometry and three‑flute design simplify chip evacuation in typical keyway depths, helping to avoid rework. Although specific cutting speeds depend on the workpiece and machine, maintaining correct feed per tooth and ensuring a secure Weldon clamp are key to achieving repeatable results. Regular inspection for flank wear and reconditioning where possible will extend service life and protect component tolerances, supporting uninterrupted production in busy workshops.

FAQ

What materials can be machined with this cutter?
The Keyway cutter DIN 327 Type N is very suitable for cast iron and low‑to‑medium strength steels (approx. 800 N/mm² uncoated); coating the tool increases capability to roughly 1000 N/mm².

Is this tool suitable for stainless steel?
Stainless steel is conditionally suitable with this cutter; the tool will perform better with optimised feeds and speeds or a coated variant to reduce work hardening and extend tool life.

Which clamping system is required?
A Weldon‑style toolholder that accepts a Ø16 mm Weldon shank is required to secure the cutter and ensure repeatable concentricity during milling.

Can the cutter produce deep keyways?
The cutter’s design supports keyways with larger depth; the short form factor improves stiffness and helps maintain dimensional accuracy for deeper slots.
