Product Description

The SECO 00023234 is a solid carbide corner radius end mill designed for high-precision milling in demanding machining environments. It features a 0.5 mm cutting diameter, a 0.05 mm corner radius, and a 0.7 mm length of cut, making it well suited for fine detail work in small-scale components. The two-flute, right-hand spiral geometry combined with a MEGA-T coating supports extended tool life across a range of workpiece materials. With an overall length of 40 mm and a 3 mm straight-cylindrical shank, it is sized for use in CNC machining centers and high-speed milling spindles. This tool is installed and operated by machinists and CNC tooling specialists.

This end mill is appropriate for precision milling of small features in materials classified under primary workpiece material codes H, M, N, P, and S, covering hardened steels, stainless steels, non-ferrous metals, general steels, and superalloys. Its extended reach design, with a 2.5 mm reach length and 0.45 mm neck diameter, allows access to recessed features and tight pockets. It is centercutting and capable of plunge operations. The JM905 series designation identifies it within the SECO product family for micro-diameter end mills.

Key Features

  • 0.5 mm cutting diameter with a 0.05 mm corner radius for controlled edge geometry
  • Solid carbide construction for rigidity and wear resistance at micro-scale diameters
  • MEGA-T coating extends tool life across hardened, stainless, and superalloy materials
  • Extended reach design with 2.5 mm reach length and 0.45 mm neck diameter for deep or recessed features
  • Centercutting, single-end configuration supports both peripheral and plunge milling
  • Maximum TIR of 0.01 mm ensures consistent runout performance in precision setups

Compatibility

Designed as a direct-fit replacement or standard tooling option within the SECO JM905 series. Compatible with workpiece material codes H, M, N, P, and S as stated in the product specification data. Fits standard 3 mm straight-cylindrical collet holders and tool holders used in CNC milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the collet and tool holder are clean and within specified runout tolerance before seating the shank. Confirm spindle is fully stopped and machine is in a safe state before tool changes. At micro diameters, excessive clamping torque or contaminated collets can cause deflection or premature tool failure.
