End mill Type N D.4 mm – Solid carbide, TiSiN-coated (TECWERK)

The End mill Type N D.4 mm Solid Carbide TiSiN 45° HA is a mini end mill designed for high‑speed cutting and universal use in steels and non‑ferrous materials, supplied with a cylindrical shank to DIN 6535 HA.

• Solid carbide (VHM) for high rigidity
• TiSiN coating for extended tool life
• 45° helix and three flutes for smooth chips
• Cylindrical shank DIN 6535 HA, shank Ø 4 mm

Consistent rigidity and runout control for precision milling

Constructed from solid carbide, the cutter offers high stiffness that reduces deflection during aggressive cuts. The compact geometry and short overall length are optimised for stability in operations where minimum chatter and repeatable tolerances are required. Shank tolerance is held to h6, enabling secure clamping and low runout when used with collets and holders that meet the same standard. This combination supports tight dimensional control in production and repair work.

Coating and flute geometry that extend tool life and aid chip control

The TiSiN surface layer increases hardness and heat resistance, lowering wear rates under thermal load and enabling longer tool life in interrupted or continuous cuts. With a 45° helix and three‑flute configuration, the geometry produces favourable shear action and reliable chip evacuation, especially in high‑speed cutting (HSC). Right‑hand cutting direction is provided for conventional toolpaths; the geometry is therefore suited to finishing passes and applications that demand fine surface quality.

Application spectrum and machining benefits

Designed as a universal solution, this cutter is very well suited to steel and non‑ferrous metals, while remaining conditionally suitable for harder materials and special alloys. The tool is intended for HSC applications where surface integrity and productivity are prioritised. Compliance with DIN 6527 and the cylindrical shank per DIN 6535 HA ensure compatibility with standard toolholding systems, simplifying tooling decisions across diverse production environments.

Key dimensions and practical integration on the machine

With a nominal diameter of Ø 4 mm, an overall length of 50 mm, a cutting length of 3 mm and an effective length of 11 mm, the tool is configured for short‑reach, high‑precision tasks. The three cutting edges reduce cutting forces per flute while maintaining feed capability, and the right‑hand cut supports conventional machining strategies. The compact profile allows close workpiece access and is especially useful where fixture space is limited or where fine finishing passes are required.

FAQ

What materials is this cutter best suited for? The TECWERK end mill is very well suited to steel and non‑ferrous metals; it is conditionally suitable for harder materials and special alloys.

How does the TiSiN coating benefit machining? TiSiN on this solid carbide cutter increases thermal resistance and reduces wear, which prolongs tool life and supports higher cutting speeds in HSC operations.

What does the 45° helix do for chip formation? A 45° helix on the cutter improves shearing action and chip evacuation, resulting in smoother surface finish and reduced cutting forces during finishing passes.

Is the shank compatible with standard collets and holders? Yes, the tool is supplied with a cylindrical shank to DIN 6535 HA and shank tolerance h6 for secure clamping in standard toolholders.

How many flutes does the cutter have and what is the effect? The cutter features three flutes, which balance chip space and cutting edge engagement to enable stable, efficient milling in a range of materials.
