End mill DIN 844 Type HR D14 by TECWERK — HSS‑Co5, TiCN, Weldon shank

The End mill DIN 844 Type HR D14 is a short, four‑flute HSS‑Co5 cutter with a TiCN coating, centre‑cutting geometry and a Weldon shank, engineered for milling steel and cast iron in general workshop and light industrial applications

• HSS‑Co5 core for higher red hardness
• TiCN coating for extended tool life
• Weldon shank with drive flat for secure grip
• Four‑flute centre‑cutting for axial plunging

High-performance alloy and coating for longer cutting intervals

The short, rigid construction is built around a HSS‑Co5 substrate, which increases red hardness and resistance to thermal softening compared with standard high‑speed steels. The TiCN coating reduces adhesive wear and improves surface hardness, which together extend service life and maintain edge stability. With an effective cutting length of 36 mm and a nominal diameter of 14 mm, the cutter is dimensioned for stable pocketing and slotting operations where chatter must be minimised. For materials selection, the tool handles steels very well and is also well suited to cast iron; note that its practical work limits reach approximately 800 N/mm² with an uncoated tool and up to 1200 N/mm² when coated, which translates into dependable performance across many common components.

Secure clamping and geometry that enables plunge milling

A cylindrical shank with a Weldon drive flat ensures positive torque transmission and reduces slippage in set screws or hydraulic chucks. The tool’s four‑flute layout balances metal removal rate and finish quality: additional cutting edges increase material engagement without forfeiting rigidity. The centre‑cutting design permits axial plunging, which simplifies operations that require entry into a workpiece from above, such as spot drilling followed by milling. The short Type HR form increases rigidity for precise cuts and helps to minimise deflection, resulting in predictable dimensional outcomes even in tougher sections of the workpiece.

Practical benefits for workshop throughput and tool management

Using a tool with a TiCN surface and a cobalt‑enriched core reduces the frequency of tool changes and unplanned stoppages — a direct gain in uptime for busy benches. The combination of a hardened substrate and a low‑friction coating keeps cutting forces steadier, which can lead to more uniform tool wear and fewer scrapped parts. For procurement, the compact profile and standard Weldon shank mean easy integration into existing toolholding systems. These attributes make the cutter a pragmatic choice for maintenance shops and small production runs where reliability and low lifecycle cost are priorities.

Material suitability and typical applications

The cutter is optimised for steels and cast iron (very good suitability), with conditional use on non‑ferrous metals, stainless steels and special alloys where parameters must be adjusted; this reflects the tool’s balance between toughness and wear resistance. Typical tasks include slotting, pocketing and light finishing where a short, robust cutter provides superior surface quality and dimensional control. Right‑hand cutting direction and a fine, honed flute profile contribute to consistent chip evacuation and repeatable results across batches.

FAQ

What materials is the cutter best suited for?
The TECWERK end mill is optimised for steel and cast iron (very good suitability); use on non‑ferrous metals, stainless steels and special alloys is possible but requires adapted cutting data.

Can this tool plunge axially into the workpiece?
Yes, the centre‑cutting geometry allows axial plunging, making the cutter suitable for entry operations and spot‑to‑mill transitions.

What securing method is recommended for the shank?
A clamping arrangement that engages the Weldon drive flat or a collet that fits a 12 mm shank will ensure secure torque transmission and minimise slippage.

How does the TiCN coating affect performance?
The TiCN coating enhances surface hardness and reduces adhesive wear, extending tool life and enabling higher cutting stresses compared with uncoated counterparts.

What is the effective cutting length and how does that affect rigidity?
The cutter provides an effective cutting length of 36 mm, which, combined with the short HR form, improves rigidity and reduces deflection for more accurate machining.
