End mill DIN 844 Type NR, 12 mm — HSS‑Co5 with TiCN coating (Weldon shank) by TECWERK

The End mill DIN 844 Type NR, 12 mm is a short multi‑flute cutter designed for precise milling in workshop and light production environments, offering a balance of wear resistance and secure clamping for steel and cast iron applications.

• HSS‑Co5 high‑speed steel body
• TiCN coating for extended tool life
• Effective cutting length 36 mm
• Weldon shank with drive flat

High-performance cutting for medium-strength materials

The cutter’s HSS‑Co5 substrate combined with a TiCN surface finish delivers higher wear resistance and improved heat tolerance compared with unalloyed HSS. Conforming to DIN 844, the short multi‑flute geometry is optimised for interrupted and continuous cuts where dimensional stability matters. For workshops seeking predictable results, the combination of cobalt alloy and titanium carbonitride coating means the tool performs reliably on steels up to about 1,000 N/mm² when used as a coated tool, while uncoated performance remains strong up to roughly 800 N/mm². This technical pairing prolongs tool life and maintains cutting edge integrity under regular production loads.

Precision geometry for secure clamping and superior surface finish

The cutter features 4 flutes and a 45° chamfer with a centre cutting capability and a hinterschliff (undercut) cord profile for controlled chip formation and smoother side finishes. The Weldon shank with a drive flat ensures mechanical retention in holders and reduced slippage under higher feed forces, while the 36 mm effective length gives a compact reach that minimises deflection. These design choices reduce vibration and contribute directly to improved surface quality and repeatability on workpieces, lowering rework rates and enhancing throughput in jobbing and small‑batch production.

Clear guidance for material application and machining strategy

Material suitability is explicit: very good for steel and cast iron, while non‑ferrous metals and speciality alloys are conditionally supported. The cutter is right‑hand cutting, compatible with standard milling setups. Such clarity aids process planners in reducing trial‑and‑error: select the coated variant where higher tensile strengths are encountered, and prefer the uncoated option for lower‑strength work where coating is unnecessary. This targeted use reduces inventory complexity and helps maintain cutting parameters within safe, efficient ranges.

Operational efficiency that supports reliable workflows

The short, multi‑flute format of this tool allows generally higher feed rates for a given spindle speed, translating into shorter cycle times for typical workshop operations. The TiCN coating contributes to longer intervals between tool changes and reduces downtime, while the DIN 844 designation provides a recognised specification for procurement and quality assurance. For complex or critical components, pairing the cutter with appropriate coolant and conservative feed data will further extend life and ensure consistent part quality.

FAQ

What materials is this end mill best suited for?
The TECWERK end mill (End mill DIN 844 Type NR, SKU 2000866442NW) is very well suited to steel and cast iron, with conditional suitability for non‑ferrous metals and speciality alloys; choose the coated version for higher tensile strengths.

Does the tool feature a drive flat for secure clamping?
Yes, the cutter comes with a Weldon shank including a drive flat to improve clamping security and reduce slippage during machining.

How does the TiCN coating benefit performance?
The TiCN coating on the TECWERK cutter increases wear resistance and heat tolerance, extending tool life and enabling higher performance on tougher materials compared with uncoated HSS‑Co5.

Is the cutter suitable for centre cutting and plunge milling?
The tool includes a centre cutting geometry per its Type NR specification, allowing limited plunge operations and improved entry behaviour compared with non‑centre cutting variants.

Which standard does the tool comply with and why is that important?
The cutter conforms to DIN 844, providing a recognised specification for dimensions and geometry that simplifies procurement and ensures compatibility with established machining standards.
