14mm Cutter DIN 844 NR Short HSS-Co5 Multi-Flute 36mm Cut Length, 45° Chamfer - TECWERK

Take advantage of the combination of durable HSS‑Co5 construction and a short, multi‑flute centre‑cutting design for reliable, vibration‑reduced milling in low to medium strength materials; order this tool directly via Metav Werkzeuge or consult the team for application advice.

TECWERK end mill DIN 844 Type NR, D 14 mm — HSS‑Co5, Weldon shank

The TECWERK end mill DIN 844 Type NR is a short, multi‑flute cutter designed for precision milling and plunge operations in workshop and light industrial environments.

• HSS‑Co5 high‑speed steel with 5% cobalt
• Short multi‑flute, centre‑cutting geometry
• Cylindrical Weldon shank with drive flat
• Suited to steel and cast iron up to 800 N/mm²

Consistent metal removal with a hardwearing cutting edge

The HSS‑Co5 composition provides a solid compromise between toughness and heat resistance, making this short end mill suitable for demanding intermittent cuts. The multi‑flute configuration increases material contact for smoother surface finish and higher feed rates while the centre‑cutting capability enables safe plunge milling. The 45° protective chamfer and the honed cutting‑edge profile reduce burr formation and protect the primary edge, supporting longer intervals between regrinds and steady cycle times.

Defined suitability and machining limits for reliable planning

Application data indicate effective milling of workpieces with low to medium tensile strength: up to 800 N/mm² with the uncoated tool and up to 1,000 N/mm² when a suitable coating is applied. This translates to excellent performance in most steels and cast iron grades commonly encountered in production, while non‑ferrous metals are only conditionally suitable. The specified limits help with process planning and tool selection, enabling predictable tool life and fewer unplanned tool changes on the shop floor.

Secure clamping and workshop ergonomics for everyday use

The cylindrical shank with drive flat (Weldon) ensures reliable clamping under higher torque and reduces the risk of slippage in standard holders. The short overall length improves rigidity and minimises chatter, especially in smaller machines or when performing interrupted cuts. Right‑hand cutting geometry and compatibility with DIN 844 toolholders make the cutter straightforward to integrate into existing toolsets, supporting efficient tool management and consistent production results.

FAQ

What materials is this end mill best suited for?
The TECWERK end mill is very well suited to steel and cast iron; non‑ferrous metals are conditionally suitable depending on the specific alloy and cutting parameters.

Can the tool be used for plunge milling?
Yes, the centre‑cutting geometry enables plunge operations; the cutter supports controlled axial engagement when used within the specified material limits.

What does the HSS‑Co5 designation mean for workshop use?
HSS‑Co5 denotes high‑speed steel with 5% cobalt, which improves hot hardness and toughness for tougher cutting conditions compared with standard HSS.

Is the cutter compatible with Weldon holders?
The cylindrical shank with a drive flat is designed for Weldon‑style clamping systems, providing secure fixture under higher torque loads.

What are the tensile strength limits for reliable machining?
Process planning should observe the stated limits: up to 800 N/mm² for uncoated tools and up to 1,000 N/mm² if an appropriate coating is applied.
