Osg 71201016 Square End Mill 0.3937 in 2 Flute Carbide

Product Description

The OSG 71201016 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. It features a 0.3937-inch (10 mm) cutting diameter, a 0.9843-inch (25 mm) length of cut, and a 2-flute geometry with a 30-degree right-hand helix. The diamond coating improves wear resistance and surface finish performance. The micrograin carbide substrate supports cutting at elevated speeds and feeds, making this end mill well-suited for production environments where tool life and dimensional accuracy are priorities. Installation and use are performed by machinists and tooling technicians on CNC and manual milling equipment.

This end mill is suited for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials where a square shoulder finish is required. The centercutting capability allows plunge entry into the workpiece. The right-hand cut and right-hand flute direction are standard for conventional milling machine spindle rotation. Overall length is 63 mm (approximately 2.48 inches), keeping the tool compact and rigid in close-tolerance applications.

Key Features

• 0.3937-inch (10 mm) cutting diameter with matching 0.3937-inch shank for direct collet or chuck mounting
• Diamond coating for extended wear resistance and improved chip evacuation
• Micrograin solid carbide substrate for rigidity and edge retention
• 30-degree right-hand helix promotes smooth cutting action and reduced chatter
• Centercutting design allows plunge milling without a pre-drilled pilot hole
• 2-flute geometry provides chip clearance in slotting and deep-pocket applications

Compatibility

Designed as a standard single-end square end mill with a 0.3937-inch straight shank, compatible with ER collets, end mill holders, and chucks sized for 10 mm or 0.3937-inch shank tooling on CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe state before mounting or removing the end mill. Seat the shank fully into the collet or holder and torque the retention mechanism per the holder manufacturer specification. Verify runout with a dial indicator before beginning production cuts to protect both the tool and the workpiece.
