TECWERK long HSS-Co PM end mill DIN 844 HR, 6 mm, 4-flute, Weldon shank

The TECWERK long HSS-Co PM end mill DIN 844 HR 6 mm is designed for precision machining of high-strength steels and stainless steels, combining a centre-cutting four-flute geometry with a Weldon shank for secure tool holding.

• HSS-Co PM for increased wear resistance
• ALCRONA coating for prolonged tool life
• Centre-cutting four-flute geometry
• Weldon shank with drive flat for secure clamping

Precision and durability for high-strength machining

The use of HSS‑Co PM (powder-metallurgy high-speed steel with cobalt) delivers a combination of hardness and toughness that resists flank wear while retaining edge integrity under load. The ALCRONA coating reduces friction at the cutting edge and improves tool life, which in turn supports longer uninterrupted production runs when machining materials up to approximately 1400 N/mm² tensile strength. These material and coating choices make the cutter a reliable option where both surface finish and tool life are priorities.

Secure clamping and improved stiffness for stable cuts

A Weldon shank with drive flat ensures positive tool retention in standard holders, reducing the risk of slippage during heavy cuts. The tool’s long design benefits from an engineered tapered flute root that increases stiffness compared with conventional long cutters, improving dimensional stability in deeper pockets and slots. The centre-cutting capability permits plunge operations when required, while the four-flute profile balances material removal rate and surface finish.

Reduced changeovers and consistent productivity

The geometry and materials are optimised to minimise downtime: fewer tool changes are needed thanks to durable substrate steel and surface treatment, and the protective 45° chamfer reduces edge chipping during engagement. Suitability ratings include very good for steel, stainless steel and cast iron, with conditional use on non-ferrous and certain special alloys, allowing a single cutter to cover a wide range of tasks and reduce tooling complexity on the shop floor.

Practical applications and handling notes

This long, 6 mm diameter end mill is well suited for CNC slotting, pocketing and finishing in small-to-medium batch production, especially where access depth requires an extended reach. The centre-cutting feature enables direct plunging; however, monitoring feed rates and ensuring correct holder rigidity remain important to preserve tool life. The right‑hand cutting direction and cylindrical shank with drive flat fit standard setups, simplifying integration into existing machining cycles.

FAQ

What materials can this end mill handle effectively?
The TECWERK long HSS‑Co PM end mill is rated very good for steel, stainless steel and cast iron and is conditionally suitable for some non‑ferrous metals and special alloys.

Is the cutter suitable for plunging operations?
Yes, the centre‑cutting design permits plunging; the cutter’s geometry supports direct entry when correct feeds and rigid clamping are used.

What are the advantages of the ALCRONA coating on this tool?
The ALCRONA coating reduces friction at the cutting edge and enhances wear resistance, extending the life of the HSS‑Co PM substrate under demanding conditions.

How does the Weldon shank improve reliability in the holder?
The Weldon shank with drive flat provides positive engagement in standard tool holders, minimising slippage and ensuring consistent axial and radial stability during heavy cuts.

For which applications is this long 6 mm cutter best chosen?
Its extended reach and four‑flute geometry make it suitable for CNC slotting, pocketing and finishing where access depth or component geometry requires a long tool.
