TECWERK 6 mm HSS‑Co PM ALCRONA‑coated long 4‑flute end mill (DIN 844 Type N, Weldon shank)

The TECWERK 6 mm HSS‑Co PM ALCRONA‑coated long 4‑flute end mill is a centre‑cutting, right‑hand cutter designed for slotting and plunge operations in steel, stainless steel and cast iron up to approximately 1000 N/mm².

• ALCRONA coating for extended tool life
• HSS‑Co PM for high tensile strength materials
• Weldon shank with drive flat for secure clamping
• Uneven flute split for reduced vibration

Consistent cutting performance for high‑strength materials

Built from HSS‑Co PM, this long four‑flute cutter delivers stable cutting in demanding materials. The ALCRONA-coated surface increases wear resistance and reduces friction, which helps to maintain cutting geometry over longer runs. Thanks to the centre‑cutting design and a rated capability for materials up to 1000 N/mm², the tool is particularly suitable for operations in steel, stainless steel and cast iron, offering a dependable balance between edge life and material removal rates. The solid construction also supports intermittent cuts and frequent tool engagement without rapid edge deterioration.

Improved rigidity and vibration control for better surface finish

Stability is enhanced by a conical flute base that raises local stiffness and a deliberately uneven flute split that dampens harmonics during rotation. Together these features reduce chatter tendencies and improve dimensional repeatability. The 4‑flute geometry provides a favourable compromise between chip evacuation and cutting engagement on medium to hard materials, while the tool’s long configuration allows reach into deeper features without sacrificing support. For workshop setups where minimising rework and maximising first‑pass quality matter, these design choices translate into fewer rejects and shorter secondary finishing operations.

Practical handling and versatile machining options

The Weldon shank with drive flat simplifies secure clamping in milling holders and end mill chucks, reducing the risk of slippage under higher torque. As a centre‑cutting and right‑hand cutting tool, it enables controlled plunge milling as well as conventional side‑milling and slotting operations, which makes it a versatile option for both prototype work and serial machining. The long flute length supports deeper slotting and pocketing tasks; when clamped correctly, the cutter maintains repeatable axial run‑out and consistent cutting forces across production batches.

Efficient workshop economics and supply reliability

By combining a robust substrate with an advanced coating and proven geometrical measures, this cutter reduces downtime and tooling turnover in daily production. Lower tool-change frequency and improved first‑pass accuracy contribute to measurable savings on machine hours and labour. When sourced through established distributors, workshops also benefit from dependable stock levels and technical advice, making it easier to plan jobs and maintain throughput without compromising on precision.
