Description
The SECO 10023020 is a single-end square end mill engineered for precision material removal in aluminum and non-ferrous metals. Built from micrograin solid carbide, it delivers rigidity and edge retention that high-speed steel cannot match at elevated cutting speeds. The 3-flute geometry balances chip evacuation and surface finish, making it well suited for slotting, profiling, and peripheral milling operations. A 45-degree right-hand helix promotes efficient chip flow and reduces cutting forces on the workpiece. The ANF coating further extends tool life when machining gummy or abrasive non-ferrous alloys. Machinists and CNC operators install this tool in vertical and horizontal machining centers where consistent diameter tolerance is required.
This end mill is designed for primary use in aluminum and non-ferrous workpiece materials, consistent with Series A345 tooling intended for high-speed, low-force cutting strategies. It is centercutting, allowing plunge entry in addition to standard peripheral and slotting passes. The straight shank seats directly in standard collet chucks and end mill holders with a 1/2 inch bore. It is appropriate for both production-floor CNC work and manual knee-mill applications where a standard-length reach is sufficient.
Key Features
- Micrograin solid carbide construction for superior rigidity and edge retention
- ANF coating optimized for aluminum and non-ferrous alloy machining
- 3-flute design balances chip clearance and finish quality
- 45-degree right-hand helix reduces cutting forces and improves chip evacuation
- Centercutting geometry allows plunge milling entry
- Right-hand cutting direction with straight shank for standard collet and end mill holder compatibility
Compatibility
Designed for use in standard 1/2 inch collet chucks and end mill holders on vertical or horizontal machining centers. Primary workpiece material compatibility is aluminum and non-ferrous metals (material code N) per Series A345 specifications.
Installation Notes
Installation is performed by machinists or CNC technicians using a torque wrench and appropriate collet or end mill holder rated for the shank diameter. Always ensure the machine spindle is fully stopped and locked out before tool changes. Verify tool runout against the stated TIR maximum of 0.005 inches after seating to confirm proper holder engagement. Do not exceed the rated depth of cut for the listed length of cut to avoid deflection or tool breakage.
