20mm Solid Carbide End Mill DIN 844 Type N 4-Flute Short Centre Cutting Cylindrical Shank Weldon, HSS-Co8 - TECWERK

The combination of HSS‑Co8 hardness, a rigid short DIN 844 Type N profile and a secure Weldon shank yields reliable chip removal and stable tool life in heavy shop use; order the TECWERK short 4‑flute HSS‑Co8 end mill directly via Metav Werkzeuge or consult the specialists for application guidance

TECWERK short DIN 844 Type N 4‑flute end mill, D 20 mm, HSS‑Co8 (Weldon)

A TECWERK short DIN 844 Type N HSS‑Co8 end mill engineered for milling steel and cast iron with centre‑cut capability and a Weldon shank for firm clamping

• HSS‑Co8 high‑cobalt high‑speed steel
• Short DIN 844 type N for compact machining
• 4‑flute design with centre cutting
• Weldon shank with drive flat for secure clamping

High metal‑removal rates with controlled tool life

The combination of HSS‑Co8 construction and a 4‑flute geometry delivers increased cutting edge stability and predictable wear behaviour when machining medium‑strength materials. The tool is specified for uncoated use on materials up to 800 N/mm², and when used with an appropriate coating it is rated to about 1,000 N/mm², enabling a balance between cutting speed and service life. The DIN 844 short design reduces overhang and enhances rigidity, which translates into consistent surface finish and fewer reworks in serial production.

Versatility for plunge and peripheral milling operations

A centre‑cutting geometry allows safe plunge cuts as well as conventional peripheral milling, expanding the tool’s application range in one cutter. The Weldon shank with drive flat provides a positive torque transfer and minimises slippage under higher feed forces, ensuring stable machining on both manual and CNC millers. Right‑hand cutting and a Type N profile make the cutter particularly suitable for interrupted cuts and roughing passes where robustness is required rather than fine finishing.

Workshop efficiency through predictable specifications

The short, robust design reduces the need for frequent tool changes in small batches and repair work, supporting lean workshop workflows. Material suitability is clearly defined: very good for steel and cast iron, and limited for some non‑ferrous metals and stainless steels, allowing planning of tool sets according to job mix. Technical queries or specific machining scenarios can be clarified by Metav’s technical team, ensuring the right cutter grade and clamping arrangement are selected for each application

FAQ

Is this cutter suitable for plunge milling?
The TECWERK short HSS‑Co8 end mill has centre‑cutting geometry, so it is suitable for plunge milling as well as peripheral cutting.

Which materials are best machined with this tool?
The cutter is very well suited to steel and cast iron; non‑ferrous metals and stainless steels are workable but only with limited efficiency.

Can the tool cope with interrupted cuts?
The high‑cobalt HSS‑Co8 composition and short Type N design provide robustness for interrupted and roughing operations.

What does the Weldon shank provide in practice?
The Weldon shank with drive flat ensures secure clamping and reliable torque transfer, reducing the risk of slippage during heavy feeds.

Does the DIN 844 short design benefit small machines?
Yes, the reduced overhang of the DIN 844 short form increases rigidity and is particularly advantageous on compact milling machines.
