End mill DIN 844 Type HR, Ø12 mm — HSS‑Co5, TiCN, Weldon shank

a robust End mill DIN 844 Type HR designed for demanding milling in steel and cast iron, offering extended tool life through a hard-wearing TiCN coating

• DIN 844 Type HR long profile
• HSS‑Co5 with TiCN coating
• Four‑flute geometry for stable cutting
• Cylindrical shank with drive flat

Precision coating and substrate for longer tool life

The combination of HSS‑Co5 substrate and TiCN coating delivers a balance of toughness and surface hardness that reduces flank wear and preserves the cutting edge under intermittent loads. The tool conforms to DIN 844, a standard for long‑profile end mills, which ensures consistent geometry across batches. This material and coating pairing is particularly advantageous when machining abrasive steels and cast iron, as the coating reduces adhesion and thermal softening during milling.

Predictable chip control and improved surface finish

The four‑flute design, paired with a centre‑cutting geometry and a fine, back‑relieved chord profile, supports controlled chip formation and evacuation. A 45° chamfer on the cutting edges reduces entry forces and vibration, yielding a smoother machined surface and lower spindle load. For operators less familiar with these terms: centre‑cutting means the tool can perform light plunge cuts; the chord‑style profile refines the cutting engagement to improve finish with minimal burr formation.

Secure clamping and extended reach for consistent production

Equipped with a Weldon shank (drive flat) and a 63 mm cutting length, the tool provides secure transmission of torque and reduced risk of slippage in the holder. The overall length of 110 mm and a Ø12 mm shank give the reach required for deeper pockets while maintaining rigidity. Using a Weldon interface lowers the chance of re‑clamping during longer runs, improving repeatability and helping to maintain process stability on small to medium batch sizes.

Application guidance and material suitability

This long‑profile cutter is rated for work up to approximately 1200 N/mm², making it very well suited to steels and cast iron, while being conditionally suitable for non‑ferrous metals, special alloys and stainless steel (INOX). The TiCN coating enhances performance on abrasive and adhesive materials by reducing friction and heat build‑up; however, for highly ductile alloys, a different geometry or coating may offer better results. Selection of spindle speed and feed should follow material‑specific guidance to preserve tool life and surface quality.

FAQ

Which materials are best machined with this tool?
The TECWERK end mill DIN 844 Type HR (SKU 2000866552NW) is very well suited to steel and cast iron; it is conditionally suitable for non‑ferrous metals, special alloys and stainless steel.

Can the cutter be used for light plunge cuts?
Yes, the centre‑cutting geometry enables limited plunge milling and ramping operations, as described for the DIN 844 Type HR design.

How does the TiCN coating affect performance?
The TiCN coating reduces friction and improves wear resistance during milling, extending tool life and improving surface finish on more abrasive steels and cast iron.

What does the Weldon shank provide in practice?
A Weldon shank with drive flat offers secure clamping and reliable torque transmission, lowering the risk of slippage during longer or higher‑load operations.

Which standard ensures the tool geometry and interchangeability?
The tool complies with DIN 844 (Type HR), which standardises the long‑profile end mill geometry for reproducible performance and interchangeability across batches.
