Take advantage of a long Type N profile, HSS‑Co8 composition and a secure Weldon shank to maintain uninterrupted milling cycles in mixed‑material workshops; order the cutter directly via Metav Werkzeuge or consult the Metav team for application guidance.

TECWERK HSS‑Co8 Long Type N End Mill, 16 mm, 4‑Flute, Weldon Shank (DIN 844)

The TECWERK HSS‑Co8 Type N end mill is a long, centre‑cutting, four‑flute milling cutter designed for roughing and finishing operations in steel and cast iron within general workshop and production environments

• HSS‑Co8 construction, high wear resistance
• DIN 844 Type N, long profile
• Four flutes, centre‑cutting geometry
• Weldon shank with drive flat for secure clamping

Deep milling and secure clamping for consistent throughput

Manufactured to DIN 844 as a Type N long profile, this HSS‑Co8 cutter combines extended reach with a robust shank design to keep set‑ups stable during deeper passes. The Weldon shank with drive flat provides positive engagement in high‑torque holders, reducing slippage and downtime. With a 16 mm diameter and an effective length of 73 mm, the tool is tailored to jobs that require both reach and rigidity. The cobalt alloy increases hot hardness, so the tool retains cutting edge stability under thermal load, which translates into fewer tool changes and steadier production cycles.

Material adaptability and reliable cutting performance

The geometry is optimised for a range of substrates: very good suitability for steel, especially unalloyed and medium‑strength grades, and very good performance on cast iron. Non‑ferrous metals and stainless steels are conditionally suitable, depending on cutting data and coolant strategy. The four‑flute layout balances chip evacuation and surface finish, while the centre‑cutting capability enables limited plunge milling when required. For routine workshop applications the combination of cobalt‑enhanced HSS and the Type N long profile delivers a dependable compromise between toughness and wear resistance.

Precision geometry that reduces rework and cycle times

The cutter’s four cutting edges and right‑hand cut geometry produce a consistent finish on machined faces, minimising post‑machining operations. The relatively long overall length of 123 mm supports reach into recessed features without sacrificing concentricity when clamped correctly. The specified relief / clearance measure (15 mm free relief) helps prevent rubbing on extended engagements and supports smoother entry and exit from the workpiece. These design choices contribute to predictable dimensional results and lower scrap rates in repetitive production.

Integration into workshop processes and tool management

This end mill fits standard toolholders designed for cylindrical shanks and benefits from common clamping systems because of the Weldon flat. The cutter is supplied as a single unit, allowing straightforward inventory control and rapid replacement planning. Given its construction and DIN conformity, the tool integrates easily into existing machining strategies and programming parameters. Technical teams will appreciate the clear measurable data—diameter, lengths and flute count—that allow immediate adaptation of feeds and speeds for optimised material removal rates.

FAQ

What materials is this end mill best suited for?
The TECWERK HSS‑Co8 long Type N end mill is very well suited for steel and cast iron; non‑ferrous metals and stainless steel are conditionally suitable depending on cutting parameters.

Can this cutter perform plunge milling?
Yes, the centre‑cutting geometry enables limited plunge operations, so the cutter can be used for spot drilling and short plunges in appropriate setups.

Which DIN standard does the tool conform to and why is that important?
The tool conforms to DIN 844 Type N, which defines the long profile and tolerances, ensuring predictable fitment and performance in standardised holders.

How does the Weldon shank benefit clamping in production?
The Weldon drive flat prevents rotational slip under torque, providing more secure clamping than plain cylindrical shanks when used with compatible holders.

What are the key dimensions to consider when programming feeds and speeds?
Relevant dimensions are 16 mm diameter, 73 mm effective length and 123 mm overall length, plus the four‑flute geometry; these determine engagement, chip load and rigidity considerations.
