10mm Cylindrical Shank End Mill HSS-Co8 53mm Effective Length 4-Flute Right-Hand - TECWERK

Combining HSS‑Co8 material, a four‑flute geometry and a long shank with a drive flat, this cutter offers dependable material removal and secure clamping for deep features. Order the tool directly via Metav Werkzeuge or consult their specialists for tailored application advice.

HSS‑Co8 end mill DIN 844 Type N, 10 mm — Long shank, 4 flutes (TECWERK)

The HSS‑Co8 end mill DIN 844 Type N, 10 mm is a long‑reach, centre‑cutting four‑flute cutter designed for machining steels and castings in general engineering and toolrooms

• HSS‑Co8 for high wear resistance
• Long shank for deep pocket access
• Four‑flute geometry for high metal removal
• Centre‑cutting for plunge capability

Consistent performance on medium‑strength steels and castings

The tool is made from HSS‑Co8, a cobalt‑alloyed high‑speed steel that retains hardness at elevated temperatures and extends tool life under load. With a four‑flute profile and DIN 844 specification, the cutter is optimised for steady stock removal and good surface finish when working on materials up to 800 N/mm² with an uncoated tool. The higher hot‑hardness of the alloy reduces flank wear and supports reliable cycle times in repetitive production tasks. For users with limited metallurgy experience, cobalt‑alloy HSS means improved toughness compared with plain high‑speed steel, helping to avoid premature chipping during interrupted cuts.

Access deep features with secure clamping and reduced chatter

A 95 mm overall length and 53 mm effective length provide the reach required for recessed pockets and stepped components while a 10 mm shank maintains stiffness. The cylindrical shank with drive flat ensures positive clamping in standard toolholders and reduces slippage during heavy cuts. The combination of long reach and a robust shank geometry minimises vibration, which improves dimensional stability and reduces the need for finishing passes. Relief geometry including a 9.5 mm clearance area supports chip evacuation near the neck and aids consistent cutting behaviour on longer tool overhangs.

Plunge capability and material suitability for practical workshop use

Thanks to centre‑cutting geometry and right‑hand cutting, plunge milling and conventional milling operations are both feasible, broadening application possibilities for the tool. The cutter shows very good suitability for steel and castings, while performance on non‑ferrous metals and stainless steels is conditional; the tool is supplied uncoated, which is adequate up to the stated strength class, whereas a coated variant can raise allowable material strength to around 1200 N/mm². For practical selection, consider workpiece hardness and surface finish demands: the tool excels where robust stock removal and tool life matter more than ultra‑fine finishing.

FAQ

What materials is this cutter best suited for?
The TECWERK HSS‑Co8 end mill DIN 844 Type N is very well suited to steel and castings; performance on non‑ferrous metals and stainless steel is conditional depending on cutting data.

Can the cutter be used for plunge milling?
Yes. The centre‑cutting geometry of the cutter allows plunge milling as well as conventional side milling, expanding its practical applications.

What diameters and shank size does the tool have?
The tool has a 10 mm diameter and a 10 mm shank, with a 95 mm overall length and 53 mm effective cutting length to reach deeper features.

Is the cutter coated and how does that affect material limits?
The supplied tool is uncoated; with an uncoated HSS‑Co8 tool the recommended material strength limit is around 800 N/mm², while a coated variant can increase that limit towards 1200 N/mm².

How many flutes does the cutter have and what are the benefits?
The cutter features four flutes, which provide a good balance between metal removal rate and surface finish, and support stable cutting in medium‑strength materials.
