TECWERK Keyway Cutter DIN 844 Type N — 15 mm, HSS‑Co8, TiCN, Weldon, 3‑flute (long)

A TECWERK keyway cutter DIN 844 Type N designed for milling keyways and slots in medium‑strength steels and stainless steel, long version with Weldon shank for secure clamping.

• HSS‑Co8 substrate for enhanced heat resistance
• TiCN coating for reduced friction and wear
• Long 3‑flute design for deep slotting
• Weldon shank Ø12 mm for rigid holding

Higher machining performance through alloy and coating

The use of HSS‑Co8 (high‑speed steel with cobalt) combined with a TiCN coating gives a clear performance advantage when machining demanding materials. Cobalt in the substrate increases hot hardness and resistance to thermal softening, while the titanium carbonitride layer reduces friction and improves wear resistance. This combination enables stable cutting at higher surface speeds and extends service life compared with unalloyed HSS. For workshop planning, note the cutter is specified for work up to approx. 800 N/mm² with an uncoated tool and up to 1,000 N/mm² when the TiCN coating is engaged, which translates into fewer tool changes and a more economical production flow.

Design that improves stability, chip control and accuracy

The long body with three flutes and right‑hand cutting geometry facilitates efficient chip evacuation and balanced cutting forces in keyway and slot milling. Important dimensions such as a nominal diameter of 15 mm, cutting length 3 mm, effective length 36 mm and an overall length of 83 mm are engineered for access into narrow slots while maintaining stiffness. The Weldon shank with Ø12 mm and the 11.5 mm free relief ensure stable clamping and reduced run‑out, which together contribute to consistent slot widths and surface finish. These design choices reduce vibration and support repeatability when producing precision keyways to DIN standards.

Practical advantages for industrial and trade workshops

Compliance with DIN 844 Type N ensures compatibility with established tooling setups and makes integration into CNC or manual milling workflows straightforward. The cutter’s suitability for steel, stainless steel and cast iron (very good) and conditional suitability for non‑ferrous metals and special alloys means a single tool can cover many common workshop tasks. Reduced cycle times and longer tool life deliver a favourable cost‑benefit ratio for series production and repair work. For complex or high‑precision applications, the tool supports controlled machining strategies where tool life and process stability are priorities.

FAQ

What materials is this keyway cutter best suited for?
The keyway cutter is very well suited for steel, stainless steel and cast iron; it is conditionally suitable for non‑ferrous metals and special alloys according to the technical notes for the TECWERK cutter.

How does the TiCN coating affect performance?
The TiCN coating on the TECWERK cutter lowers cutting friction and increases wear resistance, allowing higher cutting speeds and extended tool life compared with uncoated HSS‑Co tools.

What diameter and shank size does the cutter have?
This long version has a nominal diameter of 15 mm and a Weldon shank of 12 mm, designed for rigid clamping in standard Weldon holders.

Is the cutter compliant with industry standards?
Yes, the cutter conforms to DIN 844 Type N geometry, ensuring compatibility with common machining setups and predictable cutting behaviour.

Can this cutter be used for deep narrow slots?
The long, three‑flute design and the effective length of 36 mm support machining of deeper slots while maintaining chip evacuation and dimensional stability.
