16mm Cylindrical End Mill HSS-Co8 4-Flute Short 15mm Relief Right-Hand DIN 844 - TECWERK

Benefit from the combination of HSS‑Co8 construction, a Weldon shank and a four‑flute, centre‑cut geometry for consistent, rigid milling results; order the short end mill directly via Metav Werkzeuge or ask our consultants if needed.

End mill DIN 844 Type N — 16 mm, HSS‑Co8, Weldon (TECWERK)

The End mill DIN 844 Type N — 16 mm is a short, four‑flute, centre‑cut cylindrical‑shank cutter designed for machining steels and cast iron with a focus on rigidity and repeatable results

• HSS‑Co8 high‑cobalt construction
• Four‑flute, centre‑cut geometry
• Weldon shank for secure clamping
• Complies with DIN 844 Type N standard

High‑performance material and standardised design for reliable results

Constructed from HSS‑Co8 (high‑speed steel with approx. 8% cobalt), this cutter combines improved hot‑hardness and wear resistance with toughness that reduces chipping in interrupted cuts. The DIN 844 Type N specification guarantees standard dimensions and shank form, easing integration into existing toolholders. For production environments that demand repeatable component quality, the alloy choice translates into longer tool life under elevated cutting temperatures and better resistance when machining medium‑strength steels (uncoated tools are specified for applications up to approximately 800 N/mm²). This technical composition supports efficient, predictable performance in machining routines.

Short geometry and flute design for maximum rigidity and surface quality

A compact overall length and a short effective length increase stiffness at the cutting zone; with an overall length of 92 mm and an effective length of 42 mm, the geometry helps to reduce deflection and chatter during slotting and peripheral milling. The four‑flute configuration provides additional cutting edges for a smoother feed per tooth and improved surface finish on ferrous materials, while the centre‑cut capability enables limited vertical entry where plunge cuts are required. These characteristics result in measurable benefits for cycle stability and dimensional consistency in short‑reach milling operations.

Secure clamping and recommended applications for industrial use

The cylindrical shank with a Weldon (drive flat) ensures positive drive and straightforward clamping with set‑screw holders or Weldon chucks, reducing the risk of slippage under torque. The cutter is right‑hand cutting, uncoated, and is characterised as very well suited for steel and cast iron; performance on non‑ferrous alloys and stainless steels is possible but conditional, depending on machining parameters. Because the tool is uncoated, users who require machining of harder alloys or higher contact temperatures may consider coated alternatives; for tailored recommendations on holder compatibility or process integration, technical consultation is available.

FAQ

Is this end mill suitable for stainless steel?
The TECWERK end mill (DIN 844 Type N, 16 mm) is conditionally suitable for stainless steel; performance is generally better on medium‑strength steels and cast iron, while stainless applications require careful parameter adjustment.

Can the cutter be used for plunging operations?
The cutter features a centre‑cut geometry, so the TECWERK cylindrical shank end mill can perform limited plunging, but the short cutting length and four‑flute design are optimised for rigid slotting and peripheral milling.

What clamping system is recommended for secure operation?
Use a toolholder or chuck compatible with a Weldon drive flat; the Weldon shank on the TECWERK tool ensures secure positive drive with set‑screw holders or Weldon chucks to prevent slippage under load.

Is the tool supplied with a coating for higher strength materials?
This specific TECWERK tool is supplied uncoated; the uncoated specification is appropriate for machining up to about 800 N/mm² in steels, while coated variants are available for higher temperature or harder materials.

Which materials deliver the best results with this cutter?
Best results with the TECWERK end mill are achieved on medium‑strength steels and cast iron, where the HSS‑Co8 composition and short, rigid geometry give consistent surface finish and tool life.
