End mill DIN 844 Type N, Ø 14 mm, HSS‑Co8 — long four‑flute, Weldon — TECWERK

The End mill DIN 844 Type N Ø 14 mm is a long, four‑flute, centre‑cutting HSS‑Co8 cutter designed for milling steels and cast iron in general workshop and production environments

• HSS‑Co8 high‑alloy construction
• Four‑flute centre‑cutting geometry
• Long reach with 63 mm effective length
• Weldon shank with drive flat for secure grip

High‑alloy design for consistent machining performance

The combination of HSS‑Co8 substrate and DIN 844 Type N geometry ensures stable cutting performance in interrupted and continuous milling. The cobalt‑enriched high‑speed steel improves red hardness and abrasion resistance, which translates into longer tool life when finishing moderate‑strength materials. For operations where repeatable dimensions matter, the four‑flute layout balances cutting forces and chip evacuation, reducing vibration and supporting a steadier surface finish — a practical advantage for workshop production and small series manufacture.

Long reach and secure clamping reduce process interruptions

A 63 mm effective cutting length on a total length of 110 mm provides the long reach needed for deeper slots and stepped components without resorting to extensions. The Weldon shank with drive flat enables positive clamping in holders that accept a Weldon interface, minimising slippage under torque and allowing higher axial engagement. Together, these features lower the frequency of tool changes and machine downtime, improving throughput in repetitive milling tasks.

Material suitability and application guidance

The cutter is optimised for machining steel and cast iron, offering very good suitability for these materials up to typical workshop hardness ranges. The centre‑cutting geometry allows plunge milling as well as peripheral passes, which makes the tool versatile for profile work and pocketing. Note that non‑ferrous and stainless applications are conditionally possible but depend on cutting data and machine rigidity; the tool’s right‑hand cutting action supports standard feed directions and clamping strategies commonly used in CNC and manual milling.

Practical handling, set‑up and maintenance tips

A cylindrical shank of 12 mm diameter matches standard collet and Weldon holders; secure mounting and correct run‑out adjustment are essential for maximising tool life and achieving tight tolerances. Deburring and light honing of edges after resharpening preserve the precision of the cutting geometry. When reconditioning, preserve the centre‑cutting tip and flute geometry to maintain plunge capability. Regular inspection for wear and chipping will help to schedule regrinds before dimensional drift affects part quality.

FAQ

What materials is this end mill most suitable for?
The TECWERK end mill (DIN 844 Type N, Ø 14 mm, SKU 2000866384NW) is very well suited to steel and cast iron; non‑ferrous and stainless applications are conditionally possible depending on cutting data.

Can this cutter be used for plunge milling?
Yes — the centre‑cutting geometry allows plunge milling as well as conventional peripheral milling, enabling pocketing and step operations with the same tool.

What holder is required for safe operation?
A secure Weldon or compatible collet holder with a 12 mm clamping capacity is recommended to engage the drive flat and prevent slippage under torque.

How does the HSS‑Co8 substrate affect tool life?
The cobalt‑enriched high‑speed steel increases red hardness and wear resistance compared with standard HSS, which supports longer life in demanding milling of steels and interrupted cuts.
