TECWERK Keyway Milling Cutter DIN 327 Type N, Ø18 mm — HSS‑Co8, Weldon Shank

A TECWERK keyway milling cutter DIN 327 Type N engineered for precision milling of Passfedernuten (keyways) in steel and cast iron, suited to workshop and light industrial applications

• HSS‑Co8 for higher heat resistance
• DIN 327 Type N geometry, 3 flutes
• Weldon shank, 16 mm with drive flat
• For deep keyway milling in steel and cast iron

Precision cut geometry that improves cycle reliability

The short, three‑flute design with DIN 327 profile provides a balanced combination of cutting stability and material removal. Manufactured from HSS‑Co8, the tool keeps cutting edges sharper at higher temperatures than standard high‑speed steels, which benefits continuous keyway runs in medium‑strength materials. The centre cutting capability allows controlled axial entry where required, reducing the need for pre‑drilling in many keyway operations. As a result, cycle times can be shortened while maintaining dimensional reproducibility and surface integrity.

Secure clamping and reduced deflection for truer keyways

A Weldon shank with a 16 mm diameter and drive flat ensures positive torque transmission in standard toolholders, lowering the risk of slippage during start‑stop milling and when plunging into slots. The short overall length limits overhang and therefore minimises tool deflection; this provides truer slot geometry and improves repeatability on medium‑duty milling machines. The right‑hand cutting direction and optimised flute form aid consistent chip formation, which supports uninterrupted operation and reduces tool wear under comparable cutting conditions.

Material suitability and workshop efficiency explained

The cutter is specified for machining materials with low to medium tensile strength: uncoated tools are suitable for materials up to approximately 800 N/mm², while coated alternatives extend capability towards 1000 N/mm². The tool is very well suited to steel and cast iron, while performance on stainless steel and non‑ferrous metals is conditional depending on cutting parameters and coolant use. Choosing the correct feed and speed, combined with the cutter’s geometry, results in efficient chip evacuation and predictable tool life — a practical advantage for workshops aiming to reduce rework and maximise throughput.

FAQ

What materials is this cutter best suited for?
The TECWERK keyway milling cutter is very well suited for steel and cast iron; use on stainless steel and non‑ferrous metals is conditional and requires adjusted cutting parameters.

Can the cutter be used for axial plunging or only radial cuts?
As a centre‑cutting tool, the cutter permits controlled axial entry, reducing the need for separate drilling operations in many keyway applications.

What does the Weldon shank offer in daily use?
The Weldon shank with drive flat provides secure clamping and positive torque transfer, lowering slippage risk and helping to maintain slot accuracy during start‑stop operations.

Is this cutter suitable for deep keyway milling?
Yes, the short design and flute geometry are optimised for deeper keyways while keeping deflection low; however, machine rigidity and correct feeds/speeds are essential for best results.

How many flutes does the cutter have and why does that matter?
The cutter has 3 flutes; this balances cutting edge strength and chip evacuation, making it effective for medium‑duty keyway milling in the specified materials.
