DIN 844 NR end mill, 25 mm, HSS‑Co5, TiCN (Weldon) – TECWERK

A DIN 844 NR end mill designed for short, multi‑flute machining where precise chip control and secure clamping are essential for production and toolroom environments.

• Short multi‑flute design for smooth finishes
• TiCN coating for improved wear resistance
• Weldon shank with drive flat for secure clamping
• Excellent for steel and cast iron machining

Consistent material removal for medium‑strength steels

The short multi‑flute geometry delivers repeatable cutting performance when machining steels up to the indicated strength range. The combination of HSS‑Co substrate and a tight flute design reduces chatter and improves surface integrity, which is particularly beneficial for serial operations and setups with moderate rigidity. The specification to DIN 844 confirms the cutter’s form and tolerance class, allowing planners to predict process behaviour and integrate the tool into CAM cycles or shop routines with confidence.

Extended tool life through coating and substrate selection

A TiCN coating on a cobalt‑enriched high‑speed steel substrate increases resistance to abrasive wear and heat‑related softening during interrupted cuts. This results in longer intervals between regrinds and steadier tool life in mixed batches. For users unfamiliar with coatings: TiCN (titanium carbonitride) reduces friction at the cutting edge and is effective where elevated temperatures occur, while HSS‑Co retains toughness to withstand shocks. The net effect is improved uptime and fewer unplanned tool changes.

Secure clamping and straightforward application in the workshop

The Weldon shank with drive flat simplifies fixture choice and ensures a reliable torque transfer in milling holders and shrink fits that accept the shank form. With a 25 mm shaft diameter and an effective cutting length of 63 mm, the cutter suits operations requiring a compact, robust tool for shoulder work, slotting and light face milling. The tool’s right‑hand cut and centre‑cutting capability allow plunge starts when necessary, expanding its applicability without the need for specialised tooling.

Clear suitability and recommended uses

Designed as a short, multi‑edge cutter with a 45° chamfer and a relieved chord profile, the tool is particularly effective for operations on cast iron and medium‑strength steels; non‑ferrous metals and special alloys are feasible under adapted cutting data. Where higher tensile strengths are present, the TiCN coating supports performance up to the specified limits for coated tools. This ensures that procurement decisions are supported by measurable, industry‑relevant parameters rather than subjective claims.

FAQ

What materials is this DIN 844 NR end mill best suited for?
The TECWERK DIN 844 NR end mill is optimised for medium‑strength steel and cast iron, with conditional use on non‑ferrous metals and special alloys depending on cutting data.

Can the cutter be used for plunge milling?
Yes, the centre‑cutting geometry permits plunge starts; the tool’s right‑hand centre‑cutting design supports controlled plunging with appropriate feeds and speeds.

How does the TiCN coating affect performance?
The TiCN coating reduces friction and increases wear resistance at elevated temperatures, extending useful life on interrupted or abrasive operations compared with uncoated HSS‑Co tools.

Is the Weldon shank compatible with typical toolholders?
The Weldon shank with drive flat provides a secure mechanical drive for holders and chucks designed to accept a Weldon‑style clamping surface, simplifying fixture selection in production settings.
