End mill DIN 844 Type N, 3 mm, HSS‑Co8, 4‑flute, Weldon – TECWERK

A 3 mm HSS‑Co8 short end mill (DIN 844 Type N) designed for slotting, profiling and limited plunge cutting in steels and castings

• Short 4‑flute design for smooth cutting
• HSS‑Co8 for increased heat resistance
• Weldon shank with drive flat for secure clamping
• Centre‑cutting for limited plunge operations

Faster material removal with predictable results

The combination of HSS‑Co8 alloy and a four‑flute geometry delivers higher resistance to heat and wear compared with standard high‑speed steel, enabling consistent cutting at moderate feeds. The short flute length reduces deflection, which means the cutter maintains a stable cutting line when slotting or finishing shoulders in medium‑strength components. This geometry is particularly effective for repetitive operations where dimensional consistency and chip evacuation are essential, translating directly into reduced rework and improved cycle times.

Secure clamping and controlled plunging for reliable setup

Equipped with a Weldon shank and drive flat, the tool provides secure axial and torsional clamping in collets and holders, reducing slippage during interrupted cuts. The tool’s centre‑cutting capability permits limited plunge operations without a separate drill, simplifying setup when producing pockets or starting slots. Combined, these features support predictable tool behaviour in CNC and manual milling machines, lowering the risk of tool breakage during entry and improving first‑pass accuracy.

Material suitability explained for correct application

The cutter is optimised for work up to approximately 800 N/mm² with uncoated tooling and can reach higher strength thresholds if a suitable coating is applied (up to 1000 N/mm² as a general guideline). It is very well suited for steel and castings, while use with non‑ferrous metals and stainless steels is possible but should be aligned with cutting parameters and cooling strategy. Understanding these limits helps in selecting feed rates and spindle speeds that balance tool life and productivity for each workpiece batch.

Workshop benefits: efficiency, handling and maintenance

A short, high‑cobalt solid HSS cutter reduces the need for frequent tool changes in series production and simplifies inventory through a general‑purpose geometry that covers slotting and some finishing tasks. The right‑hand cutting orientation matches standard machine setups, and the cylindrical shank with drive flat ensures compatibility with common tool holders. For maintenance, the robust HSS‑Co8 core tolerates periodic resharpening, allowing longer service life and lower total tooling cost compared with indexable alternatives for small‑diameter milling.

FAQ

Is this cutter suitable for plunge cutting?
The TECWERK end mill is centre‑cutting, which allows for limited plunge operations and makes the tool suitable for starting pockets or vertical entries when used with appropriate feeds.

What workpiece materials are best for this cutter?
This HSS‑Co8 four‑flute cutter is particularly effective on steel and castings; non‑ferrous and stainless steels are possible with correct machining parameters.

Can the tool be reclamped safely in standard holders?
Yes, the Weldon shank with drive flat ensures secure clamping in common collet chucks and holders for stable operation.

What are the strength limits for safe machining?
Guidance indicates performance up to approximately 800 N/mm² with an uncoated tool and up to 1000 N/mm² when a suitable coating is applied.
