Widia 6853358 Square End Mill 1/2 in 3 Flute Solid Carbide

Product Description

The WIDIA 6853358 is a 3-flute solid carbide square end mill designed for precise milling of non-ferrous metals. It features a 1/2 inch mill diameter, a 1-1/4 inch length of cut, and a 3-1/2 inch overall length. The variable helix angle of 37/39 degrees promotes smooth chip evacuation and reduces chatter during cutting operations. The bright/uncoated finish makes this end mill well suited for aluminum, brass, copper, and similar non-ferrous workpiece materials. Machinists and tool and die professionals select this tool when close-tolerance profiling, slotting, or peripheral milling is required on non-ferrous stock.

This end mill is intended for use in CNC machining centers and manual knee mills where right-hand cutting and right-hand helical flutes are standard. The Series 3A09 design targets non-ferrous metal applications and is a practical choice for job shops, aerospace fabrication, and precision manufacturing environments that regularly machine aluminum and similar alloys. The straight cylindrical shank fits standard ER collets and end mill holders with a 1/2 inch bore.

Key Features

• Solid carbide construction provides rigidity and wear resistance compared to high-speed steel tooling
• 3-flute geometry balances chip room with core strength for non-ferrous milling
• 37/39 degree variable helix angle reduces harmonic vibration and improves surface finish
• Bright/uncoated finish is well suited for non-ferrous metals where coating adhesion can be a concern
• Non-centercutting design - intended for peripheral and slot milling, not plunge cutting
• Right-hand cut and right-hand flute direction compatible with standard spindle rotation

Compatibility

Designed as an OEM-style solid carbide end mill for use in 1/2 inch bore ER collet chucks, shrink-fit holders, or standard end mill holders on CNC machining centers and manual mills. Primary workpiece material code N indicates non-ferrous metal applications.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerances. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the collet or holder to the recommended grip length and torque the retention mechanism per the tool holder manufacturer specification. Do not use this end mill for direct plunge entry, as this is a non-centercutting design.
