TECWERK Solid Carbide End Mill D.20 mm – 38/40° Helix, 3 Flutes

The TECWERK Solid Carbide End Mill D.20mm is a long, centre‑cutting tool designed for efficient roughing and finishing of non‑ferrous components in precision and production workshops.

• Solid carbide construction for high stiffness and wear resistance
• TiAlN special coating prevents built‑up edge and sticking
• Unequal helix 38/40° for vibration‑reduced running
• Centre cutting and cylindrical shank to DIN 6535 HB

High material removal with reliable stability

Built as a solid carbide multi‑cutter with 3 flutes, this long‑reach tool enables increased feed rates while maintaining tool rigidity. The centre‑cutting geometry allows safe plunge cuts into workpieces, making the cutter suitable for pocketing and shoulder operations where direct axial entry is required. The combination of flute count and helical geometry is engineered to balance chip evacuation with material removal, yielding improved cycle times without compromising dimensional control.

Consistent surface quality through optimised helix and coating

The 38/40° helix with an unequal helix pitch reduces harmonic excitation during cutting, which translates to a vibration‑free run and better surface finish on the workpiece. A TiAlN special coating minimises adhesion of soft alloys and reduces thermal load at the cutting edge, so the tool maintains edge integrity during longer runs. These properties together convert into repeatable component quality and reduced rework.

Excellent for non‑ferrous alloys and sensitive materials

Specifically produced for machining non‑ferrous metals, the cutter performs very well in aluminium, copper and similar alloys where chip control and non‑adhesive cutting are critical. The point geometry and coating counteract built‑up edge, making finishing passes cleaner and reducing the risk of surface smearing. For shops processing high‑volume aluminium work, this tool provides a dependable route to consistent part appearance and tight tolerances.

Workshop compatibility and handling advantages

The cutter features a cylindrical shank to DIN 6535 HB for straightforward clamping in common toolholders and collets. A neck relief reduces interference in deep pocketing, while a protective chamfer 0.3 mm (45°) guards the leading edge during handling and initial engagement. Right‑hand cutting and a long design make the tool versatile for a range of fixtures and setups, helping to streamline tool inventories and reduce changeover complexity.

FAQ

What materials is this cutter best suited for?
The TECWERK solid carbide end mill is very well suited for aluminium, copper and other non‑ferrous metals due to its TiAlN coating and flute geometry.

Can the tool perform plunge cuts?
Yes, the centre‑cutting design permits axial entry, so plunge operations are feasible with appropriate feeds and speeds.

What shank standard does the cutter use?
The cutter features a cylindrical shank manufactured to DIN 6535 HB for compatibility with standard toolholders.

How does the unequal helix benefit machining?
The unequal helix reduces harmonic vibration during cutting, improving surface finish and extending tool life for the cutter in high‑feed applications.
