Seco 17003633 Ball End Mill 1/4 in 2 Flute Solid Carbide

Product Description

The SECO 17003633 is a 2-flute solid carbide ball end mill designed for milling operations in aluminum and non-ferrous materials. It features a 0.250-inch mill diameter, a 0.750-inch length of cut, and a 2.500-inch overall length with a matching 0.250-inch straight cylindrical shank. The 45-degree high helix angle promotes efficient chip evacuation, which is critical when cutting soft, gummy materials like aluminum. The bright/uncoated finish is standard for non-ferrous work where coatings can cause material adhesion. This is a single-end, center-cutting tool suited for both roughing and finishing passes. It belongs to SECO Series AB245 and ships as a single unit.

This end mill is intended for use in CNC machining centers, knee mills, and manual milling machines where tight tolerances and clean surface finishes are required on aluminum, brass, copper, and similar non-ferrous workpiece materials. The ball nose geometry makes it well suited for 3D contouring, profiling, and slotting operations. Standard length designation means it fits most collet and end mill holder setups without requiring extended-reach toolholding. Machinists and tool and die professionals working with non-ferrous components will find this tool appropriate for production and prototype work alike.

Key Features

• Solid carbide construction provides rigidity and wear resistance compared to HSS tooling
• 45-degree high helix angle promotes fast chip evacuation in aluminum and non-ferrous cuts
• Ball nose geometry supports 3D contouring, ramp entry, and radius profiling
• Center-cutting design allows plunge entry without a pre-drilled pilot hole
• Bright/uncoated finish is optimized for non-ferrous materials where coating adhesion is a concern
• Right-hand cut and right-hand spiral flute configuration for standard spindle use

Compatibility

Designed as a standard-shank replacement or new-install ball end mill for machining setups that require a 0.250-inch diameter tool in aluminum and non-ferrous applications. Compatible with any collet, end mill holder, or shrink-fit toolholder accepting a 0.250-inch straight cylindrical shank.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank to the full recommended engagement depth in the collet or holder and torque the retention hardware per the toolholder manufacturer specifications. Verify runout with a dial indicator before cutting; maximum TIR for this tool is 0.0005 inches.
