TECWERK HSS-Co long 4-flute end mill (DIN 844, TiCN-coated) – Long reach, centre-cutting milling cutter by TECWERK

The TECWERK HSS-Co long 4-flute end mill is a robust milling cutter designed for deep milling operations and general-purpose machining of steels, stainless steel and cast iron where standard tool geometries require extended reach and secure clamping

• HSS-Co8 construction with TiCN coating
• DIN 844 Type N, four-flute centre-cutting
• 73 mm effective cutting length for deep milling
• 16 mm Weldon shank with drive flat

Longer reach that keeps production moving

With an effective length of 73 mm and an overall length of 123 mm, this long-design cutter allows deeper slotting and extended engagement without frequent tool changes, improving machine uptime and process continuity. The HSS-Co substrate offers a good balance of toughness and hardness for interrupted cuts, while the TiCN coating raises surface hardness and reduces built-up edge, extending tool life under higher cutting stresses. The four cutting edges maintain feed rates and surface finish, and the DIN 844 Type N geometry ensures standardised flute and shoulder profiles for predictable performance on production machines.

Reliable material capability and defined cutting limits

Engineered for demanding materials, this cutter is specified for machining workpieces up to approximately 800 N/mm² with an uncoated tool and up to 1,200 N/mm² when the tool is coated, providing a clear guideline for application planning. The geometry is rated very good for steel, stainless steel and cast iron, and conditioned for non-ferrous metals and special alloys, allowing process planners to allocate the tool where stability and wear resistance are required. The centre-cutting design permits limited plunging, while the right-hand cutting direction matches standard spindle configurations, simplifying integration into existing toolsets.

Secure clamping and production-ready handling

Clamping security is provided by the 16 mm Weldon shank with drive flat, which minimises slippage in heavy feeds and torque conditions and supports consistent tool concentricity. The four flutes balance chip evacuation with accuracy for machined surfaces, and the centre-cut geometry reduces the need for separate plunge tools in many set-ups. Supplied to the DIN 844 specification, the cutter offers reproducible performance and straightforward replacement in industrial environments where standardisation reduces setup time and inventory complexity. The combination of proven geometry and a wear-resistant coating makes this a cost-effective option for workshops seeking predictable performance.

FAQ

What materials is this long 4‑flute end mill best suited for?
The TECWERK HSS‑Co long 4‑flute end mill is rated very good for steel, stainless steel and cast iron; it is conditionally suitable for non‑ferrous metals and special alloys.

Can the cutter be used for plunge milling?
Yes, the centre‑cutting geometry of this TECWERK cutter permits limited plunging and facilitates certain slotting operations without a dedicated plunge tool.

What advantages does the TiCN coating provide?
The TiCN coating increases surface hardness and wear resistance, improving tool life and enabling higher cutting stresses compared with an uncoated HSS‑Co tool.

How does the Weldon shank benefit machining?
The 16 mm Weldon shank with drive flat prevents slippage under heavy feeds and torque, ensuring consistent clamping and concentricity in production setups.

Is this tool compatible with standard toolholders and DIN specifications?
Yes, the geometry complies with DIN 844 Type N, supporting predictable replacement and compatibility with standard holders used in industrial milling.
