Seco 10268534 Ball End Mill 1/2 Inch 4 Flute Solid Carbide

Product Description

The SECO 10268534 is a 4-flute solid carbide ball end mill designed for demanding metal removal in steel, stainless steel, cast iron, super-alloy, and titanium applications. Built on a micrograin carbide substrate and coated with SIRON-A via PVD AlTiN process, this end mill delivers elevated heat and wear resistance at the cutting edge. With a 0.5-inch mill diameter, a 1-inch length of cut, and a 0.25-inch nose radius, it handles both roughing and finishing passes in a single tool. Right-hand cut and right-hand helical flutes with a 30-degree medium helix angle promote chip evacuation and stable engagement across hard workpiece materials.

This end mill fits single-end toolholding setups with a 0.5-inch cylindrical shank and an overall length of 4 inches, making it a regular-length tool suited for most CNC machining center applications. It is centercutting, allowing plunge and ramp entry without a pilot hole. The SIRON-A coating is well suited for dry or minimal-quantity lubrication cutting in ferrous materials and high-temperature alloys. No chipbreaker geometry or variable index is applied, keeping the profile clean for finishing contours as well as aggressive stock removal.

Key Features

• Solid micrograin carbide substrate for rigidity and edge retention in hard materials
• SIRON-A AlTiN PVD coating for high-temperature wear resistance in ferrous and super-alloy cutting
• 4 helical right-hand flutes at 30-degree medium helix for efficient chip evacuation
• Centercutting geometry enables plunge, ramp, and helical interpolation entry
• 0.25-inch ball nose radius for contour milling and 3D profiling
• Handles roughing and finishing in steel, stainless steel, cast iron, super-alloy, and titanium

Compatibility

Designed for use in CNC machining centers with 0.5-inch collet or end mill holders. Primary workpiece material codes P, M, K, and S cover steel, stainless steel, cast iron, and super-alloy and titanium per ISO material classification. Series C5341.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the 0.5-inch cylindrical shank in a precision collet or end mill holder to within the specified TIR maximum of 0.0005 inches. Ensure the spindle is fully stopped and the machine is in a safe state before tool changes. Verify toolholder runout and clamping torque per the toolholder manufacturer specifications before initiating a cut.
