TECWERK end mill (DIN 844) – HSS‑Co5, TiCN coating, 25 mm, 4‑flute

A TECWERK end mill (DIN 844, Type HR) engineered for short, high-precision milling of steel and cast iron with a Weldon shank for secure spindle engagement.

• HSS‑Co5 substrate for high strength
• TiCN coating for extended tool life
• Weldon shank with drive flat

High-performance machining for demanding steels and cast iron

The cutter combines a HSS‑Co5 high-speed steel core with a TiCN surface layer to deliver a balance of toughness and wear resistance. This geometry is optimised for materials up to approximately 800 N/mm² with an uncoated tool and up to 1,200 N/mm² when the coating is present, providing predictable performance on medium to hard steels. The result is fewer tool changes and steady cycle times, which supports efficient production planning and reduced downtime.

Geometry that improves stability and surface quality

Featuring a four‑flute, Type HR layout with centre cutting and a 45° protection chamfer, the tool is designed to enter pockets and slots cleanly while minimising chipping at the tool tip. The honed fine cord profile and relief grinding behind the cutting edges reduce cutting forces and vibration, which improves surface finish and tool life. The short flute variant ensures rigidity during interrupted cuts and heavy engagement, making it suitable for operations where dimensional accuracy matters.

Coating and substrate: why it matters for lifetime and feed rates

The TiCN coating lowers friction and increases hardness at the cutting edge, allowing higher cutting parameters compared with an uncoated tool. In practical terms, the coating supports stepped increases in feed or cutting speed in trials, while the cobalt alloyed HSS core supplies thermal stability and toughness under shock loads. For shops transitioning between non‑coated and coated tools, the combination offers a measurable improvement in service life without sacrificing edge stability.

Practical applications and handling guidance

This end mill is particularly well suited to milling steel and cast iron, and it performs acceptably on non‑ferrous metals and special alloys under adapted parameters. The right‑hand cutting direction and Weldon shank with drive flat ensure reliable torque transfer in common toolholders. When setting up, favour moderate ramping for pocket entries and verify clamping to exploit the cutter’s rigidity. For unfamiliar materials, initial trial cuts at conservative feeds will establish optimal conditions quickly.

FAQ

What materials is this end mill best suited for?
The TECWERK end mill is very well suited to steel and cast iron; it also performs under adapted conditions on non‑ferrous metals and special alloys.

Can the coated version handle harder steels than the uncoated variant?
Yes, the TiCN‑coated cutter allows machining up to around 1,200 N/mm², compared with approximately 800 N/mm² for the uncoated tool.

What does the Weldon shank provide in daily use?
The Weldon shank with drive flat ensures secure clamping and reliable torque transmission in standard holders, reducing slippage during demanding milling operations.

Is the cutter suitable for plunge milling or only peripheral milling?
The centre‑cutting geometry allows limited plunge or ramping operations; it is primarily optimised for peripheral and pocket milling with enhanced tip engagement.

How many flutes does the tool have and why does that matter?
This model has four flutes, which balances chip evacuation and cutting stability for interrupted and continuous cuts in medium to hard materials.
