TECWERK Slot Milling Cutter DIN 844 Type N, 12 mm – HSS‑Co8, TiCN, Weldon shank

TECWERK Slot Milling Cutter DIN 844 Type N, 12 mm is a long‑reach three‑flute cutter for slotting and plunge operations in steel, stainless steel and cast iron

• HSS‑Co8 substrate for high wear resistance
• TiCN coating extends tool life
• Weldon shank with drive flat for secure clamping
• Centre‑cutting geometry enables controlled plunging

Maximum cutting performance through material and coating

The combination of HSS‑Co8 substrate and a TiCN surface treatment delivers a balance of thermal resistance and reduced flank wear, making the tool suitable for sustained machining. Data indicate effective use up to ~800 N/mm² with an uncoated tool and ~1000 N/mm² when coated; this translates into fewer tool changes when processing typical workshop steels. The specified DIN 844 Type N designation signals a robust industrial geometry designed for reproducible results on components where repeatable dimensional accuracy matters.

Secure clamping and precise handling for long‑reach operations

A Weldon shank with drive flat and a shank diameter of 12 mm ensures stable clamping in standard holders and milling arbors, reducing vibration and runout for cleaner edges. The long version with three flutes supports efficient chip evacuation while maintaining stiffness for narrow slotting tasks. The cutter’s centre‑cutting capability permits safe and controlled plunging into workpieces, opening up versatile application options from slotting to light pocketing without the need for a separate end mill.

Broad material suitability reduces process complexity

The tool’s application profile shows very good suitability for steel, stainless steel (inox) and cast iron, while non‑ferrous metals and certain special alloys are listed as conditionally suitable. For many production environments this means one cutter can replace several specialised ones, speeding workflows and lowering inventory complexity. The specified nominal diameter tolerances (9, 11, 13, 15 mm → h10; other sizes → e8) underline the manufacturer’s attention to dimensional consistency for mating parts and fixtures.

Workshop integration and practical recommendations

With a free‑cut length of 11.5 mm and a design optimised for right‑hand rotation, the cutter integrates easily into standard CNC and manual milling setups. Its three‑cutter geometry assists in uniform load distribution, which supports steady feed rates and predictable surface finish. For application‑specific guidance or to confirm suitability for particular alloys or fixtures, Metav Werkzeuge can provide tailored technical advice and recommendations based on the intended machining task.

FAQ

What materials is the TECWERK slot milling cutter suitable for?
The TECWERK slot milling cutter is rated very good for steel, stainless steel (inox) and cast iron; non‑ferrous metals and special alloys are conditionally suitable according to the product specification.

Does the cutter allow plunge cutting?
Yes, the tool features centre‑cutting geometry, which permits controlled plunging as well as conventional slotting, making it suitable for applications that require entry into the material.

What size shank and clamping system are required?
The cutter has a 12 mm shank with a Weldon drive flat, designed for secure clamping in Weldon holders or compatible milling chucks to minimise slippage and runout.

How does the TiCN coating affect performance?
The TiCN coating increases surface hardness and wear resistance, extending tool life and allowing machining of higher strength materials up to approximately 1000 N/mm² when coated.

Which standard and type does the cutter conform to?
This tool conforms to DIN 844 Type N, indicating a long‑version, three‑cutter geometry intended for industrial slotting applications.
