TECWERK Keyway Cutter DIN 327 Typ N — 5 mm, HSS‑Co8, Weldon shank

The TECWERK Keyway Cutter DIN 327 Typ N — 5 mm is a short, three‑flute cutter designed for precision milling of keyways and deeper slots in shafts and hubs

• HSS‑Co8 high‑speed steel, cobalt‑reinforced
• DIN 327 Typ N short three‑flute design
• Weldon shank Ø 6 mm with drive flat

Precision performance for accurate keyways

This cutter combines the DIN 327 geometry with HSS‑Co8 material to deliver consistent profile accuracy when machining keyways. The 5 mm diameter and 3‑flute configuration provide a balance between chip removal and stable cutting forces, while the centre‑cut capability allows controlled entry for face and peripheral milling. These attributes translate into repeatable slot dimensions and reduced rework in serial production, especially where compact, deep keyways are required.

Rigidity and handling that speed up workflows

The short design and Weldon shank Ø 6 mm keep the overhang to a minimum, increasing rigidity and reducing runout during plunge or peripheral operations. With a cutting length 3 mm and an effective length 8 mm, the tool is tailored for accurate depth control in confined setups. The right‑hand cutting direction and the three‑cutting‑edge layout improve stability under intermittent cutting, helping to maintain machining tolerances and part quality across repetitive runs.

Material suitability and process guidance

Constructed from HSS‑Co8, the cutter offers improved red hardness and wear resistance compared with plain HSS. The tool is specified for work on materials with low to medium tensile strength — approximately up to 800 N/mm² with an uncoated tool; coating can extend capability towards 1000 N/mm² where applicable. Suitability is very good for steel and cast iron, and conditional for non‑ferrous metals and stainless steels, making the cutter a reliable choice for many general engineering and repair tasks.

Practical benefits for the workshop environment

The compact, normative design reduces setup complexity: a standard Weldon holder secures the shaft quickly and reliably, while the three‑flute geometry aids chip evacuation in slotting operations. This results in fewer tool changes and steadier cycle times on keyway jobs. Combined with Metav’s logistics and quality filtering from Emmerich, the cutter supports an efficient supply chain and consistent availability for small and medium‑scale production needs.

FAQ

What materials can this keyway cutter machine effectively?
The TECWERK keyway cutter DIN 327 Typ N (SKU 2000866180NW) is very well suited to steel and cast iron; non‑ferrous metals and stainless steel are only conditionally suitable according to the cutter’s specification.

Can the cutter be used for plunge cutting into a shaft end?
Yes. The cutter’s centre‑cut geometry permits controlled entry, so the tool can perform plunge operations as well as face and peripheral milling when clamped correctly.

Which holder is recommended for secure clamping of the shank?
Use a Weldon holder designed for a 6 mm cylindrical shank with drive flat to ensure accurate torque transmission and minimal runout during keyway milling.

Does the cutter require a coating to machine harder materials?
The uncoated HSS‑Co8 version is specified up to approx. 800 N/mm²; coating can increase the capability towards 1000 N/mm², so selecting a coated variant is advised for higher tensile materials.

How does the three‑flute design influence finish and chip removal?
The 3‑flute layout offers a compromise between smooth surface finish and effective chip evacuation, making it suitable for slotting deeper keyways while maintaining dimensional control.
