TECWERK end mill DIN 844 — 18 mm, HSS-Co8, 4 flutes, long shank

The TECWERK end mill is a long-reach, centre-cutting milling cutter designed for general workshop and light industrial machining of steels and castings, offering secure Weldon shank clamping and an effective cutting length for deeper slotting and profile work.

• DIN 844 Type N long shank end mill
• HSS-Co8 material for enhanced hot hardness
• 4 flutes, centre-cutting, right-hand cut
• Cylindrical shank with Weldon flat for secure hold

Durable material performance for sustained cutting

The HSS-Co8 composition delivers superior hot hardness compared with standard high-speed steels, maintaining edge strength at elevated cutting temperatures. This increases tool life when machining medium-strength steels and castings, translating into fewer tool changes and steadier cycle times. Compliance with DIN 844 ensures predictable geometry and tolerance for consistent results in series work, making the cutter suitable for both maintenance tasks and short production runs where reliability matters.

Long-reach design that supports deeper features and stability

With an overall length of 123 mm and an 73 mm effective length, the tool provides sufficient reach for slots, pockets and stepped profiles that would be difficult with standard-length cutters. The long shank geometry is balanced by a robust 16 mm shank and the Weldon shank flat, which together improve clamping security and reduce vibration. The combination of reach and a stable mounting keeps surface finish consistent across the depth of the cut and reduces the risk of chatter on moderate spindle speeds.

Reliable cutting geometry and application range

The 4 flutes and centre-cutting configuration support a combination of axial plunging and radial milling, with the flute count chosen to balance chip evacuation and cutting edge engagement. The cutter is right-hand cutting, optimised for conventional and climb milling in most CNC and manual milling setups. It is rated very good for steel and cast iron, while performance on stainless and non-ferrous materials is limited; uncoated operation is specified up to 800 N/mm², rising to 1200 N/mm² when a suitable coating is applied, enabling adaptation for tougher workpieces where required.

Efficient workshop integration and handling benefits

The standardised shank and DIN-conforming geometry simplify inventory management and holder compatibility, reducing tool-change complexity across machines. The cylindrical shank with Weldon flat enables secure retention in standard clamping systems, lowering setup times and enhancing reproducibility between operators. As an uncoated HSS-Co tool, the cutter is straightforward to resharpen and reuse, supporting circular economy practices and lowering long-term tooling costs for workshops focused on predictable, repeatable results.

FAQ

What materials is this end mill best suited for?
The TECWERK end mill is very well suited for steel and cast iron; performance on non-ferrous metals and stainless steel is limited and should be tested for specific alloys.

Can the cutter be used for plunge milling?
Yes, the centre-cutting geometry permits axial plunging as well as radial milling, enabling operations such as pocketing and stepped feature creation.

What clamping system is required?
A standard holder that accepts a 16 mm cylindrical shank with a Weldon flat ensures secure retention and repeatable concentricity.

Is the tool supplied coated?
The supplied tool is uncoated; the performance guidelines state up to 800 N/mm² uncoated and higher hardness capability if a suitable coating is applied separately.

Which SKU should be referenced when ordering?
Please reference SKU 2000866388NW when enquiring or ordering the TECWERK end mill.
