Schaftfräser DIN 844 Typ HR D.20mm Einsatz-L.52mm HSS-Co5 TiCN Weldon TW — End mill with TiCN coating and Weldon shank

The Schaftfräser DIN 844 Typ HR D.20mm is a short, centre‑cut, right‑hand end mill designed for demanding steel and cast‑iron milling where rigidity and repeatable surface finish are required

• DIN 844 Type HR short 4-flute design
• HSS‑Co5 base material with TiCN coating
• Weldon shank with drive flat
• Centre cutting, very good for steel

High productivity through material and coating optimisation

This cutter combines a HSS‑Co5 substrate with a TiCN coating to deliver a reliable balance between toughness and wear resistance. The cobalt‑enriched high‑speed steel resists chipping under interrupted cuts, while the titanium carbonitride layer reduces friction and heat at the cutting edge, extending tool life. The 4‑flute geometry and the 45° chamfer protect the edge and promote stable cutting forces, resulting in fewer tool changes and improved machine uptime. The short design further increases rigidity in clamped setups, helping to maintain a consistent surface finish in serial production.

Stable chip control and surface quality for machinists

A centre‑cutting geometry with a fine relief profile provides predictable chip formation and evacuation, especially in steels and cast iron. The tool’s right‑hand cutting and helix characteristics assist controlled swarf ejection, reducing the risk of recutting and improving edge integrity. When used uncoated, the cutter is specified for materials up to approximately 800 N/mm²; the TiCN coating extends applicability to harder workpieces up to about 1,200 N/mm², making the tool suitable for tougher components without sacrificing finish. The result is fewer reworks and more reliable process windows on CNC and manual milling machines.

Ease of mounting and dependable runout performance

A Weldon shank with a drive flat ensures secure clamping in standard tool holders and collet chucks, minimising slippage and runout in high‑torque operations. Compliance with DIN 844 Type HR provides familiar nominal dimensions and form, aiding fast tool changeover and predictable integration into existing setups. With a 20 mm shank diameter and an effective cutting length of 52 mm, the configuration suits rigid, shallow to medium‑depth passes where accuracy and repeatability are priorities. The compact design supports high feed rates under stable conditions, improving process throughput.

Application fit and workshop advantages

Engineered for versatile shop use, the cutter is particularly well matched to steel and cast‑iron machining tasks where durability and surface quality matter most. It is very well suited for steel and cast iron, while performance on non‑ferrous metals, special alloys and stainless steels is described as conditional—appropriate for certain operations but requiring process tuning. The short, robust form factor reduces chatter risk and simplifies fixture design, helping small workshops and production cells to consolidate tool inventories and streamline machining strategies.

FAQ

What materials is this end mill best suited for?
The Schaftfräser DIN 844 Typ HR D.20mm is very well suited for steel and cast iron; performance on non‑ferrous metals and special alloys is conditional and may require adaptation of feeds and speeds.

Does the TiCN coating improve tool life significantly?
Yes, the TiCN coating on this TECWERK end mill reduces friction and heat at the cutting edge, extending cutting life and enabling operations closer to the indicated 1,200 N/mm² material range when compared with the uncoated tool.

How is the cutter mounted and secured in the tool holder?
The Weldon shank on the Schaftfräser provides a drive flat for positive clamping in standard holders, reducing slippage and contributing to stable runout characteristics in production use.

Is this tool centre cutting and suitable for plunging operations?
The tool features centre cutting geometry, which allows limited plunging; however, its short, rigid form is optimised for axial engagement combined with conventional milling passes.

What standard and dimensional conformity does the cutter follow?
This cutter conforms to DIN 844 Type HR dimensions and form, offering predictable interchangeability and compatibility with existing tool change systems.
