End mill DIN 844 Type HR D.18mm — HSS‑Co5, TiCN‑coated 4‑flute long end mill (TECWERK)

The End mill DIN 844 Type HR D.18mm is a long, centre‑cutting tool designed for milling operations in demanding shop environments, offering extended reach and robust clamping via a Weldon shank.

• TiCN coating for extended wear resistance
• HSS‑Co5 core for high toughness
• DIN 844 Type HR, 4‑flute long design
• Weldon shank with 16 mm collar for secure clamping

Reliable metallurgy for consistent machining results

Built from HSS‑Co5 and finished with a TiCN coating, the cutter offers a balance of toughness and hardness that reduces flank wear and improves edge retention under interrupted cuts. The DIN 844 specification and 4‑flute geometry promote stable cutting action and a controlled chip flow, which helps to maintain surface integrity on workpieces. These attributes translate into fewer tool changes and more predictable cycle times in repetitive milling tasks, supporting efficient production planning and reduced downtime.

Reach and rigidity that support deeper operations

With an effective length of 73 mm and an overall length of 123 mm, the tool provides the reach required for recessed features while retaining sufficient rigidity for accurate machining. The Weldon shank and 16 mm shank diameter ensure dependable clamping in toolholders that accept a Weldon flat, minimising slippage during heavier axial loads. The right‑hand cutting direction combined with the centre‑cutting design allows controlled plunging when necessary, expanding the range of feasible operations without frequent tool swaps.

Geometry and edge protection for improved surface finish

The cutter’s centre cutting capability and the fine, rear‑relieved chord profile contribute to a superior surface finish and reduced burr formation on the machined edge. The integrated 45° protection chamfer reduces the risk of chipping at the tool nose during entry, and the combination of geometry and coating supports consistent results on high‑strength materials. Material suitability is reflected in the tool’s design: it is very well suited for steel and cast iron and conditionally suitable for non‑ferrous metals, special alloys and stainless steel, making it a versatile option for mixed‑material workshops.

FAQ

Is this cutter suitable for high‑strength steels?
The TECWERK end mill (DIN 844 Type HR, SKU 2000866558NW) is designed for work up to approximately 1200 N/mm² and is therefore very well suited for many high‑strength steels.

Can the tool be used for plunge milling?
Yes, the centre‑cutting geometry of the end mill allows controlled plunging operations; the Weldon shank supports secure clamping during axial engagement.

What benefits does the TiCN coating provide?
The TiCN coating on the TECWERK HSS‑Co cutter increases surface hardness and wear resistance, extending tool life and improving edge retention in short‑to‑medium runs.

Which workpiece materials are recommended?
The tool offers very good performance on steel and cast iron; it is conditionally suitable for non‑ferrous metals, special alloys and stainless steel according to the tool specification.
