Sandvik Coromant 6259469 Ball End Mill 6mm 4 Flute Carbide

Product Description

The SANDVIK COROMANT 6259469 is a solid carbide ball end mill designed for high-performance milling in demanding metalworking applications. With a 6.00 mm cutting diameter and a 13.00 mm length of cut, this single-end tool is built for both roughing and finishing operations. The 4-flute, right-hand spiral configuration with a 30-degree medium helix angle promotes efficient chip evacuation and stable cutting action. The AlCrN coating provides enhanced thermal and wear resistance, making this mill well-suited for aggressive cuts in hard and abrasive materials. It is installed and operated by machinists and CNC programmers in precision manufacturing environments.

This ball end mill is intended for use on steel, stainless steel, cast iron, and high-temperature alloys, corresponding to ISO material groups P, M, K, and S. The 3.00 mm nose radius and 80.00 mm overall length make it appropriate for contour milling, 3D profiling, and complex surface work on vertical machining centers and CNC mills. The straight-cylindrical shank with h6 tolerance ensures a secure fit in standard collet and end mill holder systems. It is part of the SANDVIK COROMANT Series 1B240, catalog number 1B2400600XA1630.

Key Features

• Solid carbide construction in material grade 1630 for rigidity and wear resistance
• AlCrN coating for elevated heat and oxidation resistance during dry or semi-dry cutting
• 4-flute right-hand spiral design supports both roughing and finishing in a single tool
• 30-degree medium helix angle promotes smooth chip flow and reduces cutting forces
• Center-cutting geometry allows plunge entry as well as lateral milling
• Straight-cylindrical shank with h6 tolerance for precise tool holding

Compatibility

Designed for use with standard collet chucks and end mill holders accepting a 6.00 mm straight-cylindrical shank. Intended for steel, stainless steel, cast iron, and high-temperature alloy workpieces in CNC milling applications. Part of the SANDVIK COROMANT Series 1B240 product family.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is in an E-stop or lockout state before changing tooling. Seat the shank fully into the tool holder to the recommended gauge line and torque the collet nut or set screws according to the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning the first cut to avoid premature tool wear or workpiece damage.
