Sgs 02647 Square End Mill 0.04 in 4 Flute Solid Carbide

Product Description

The SGS 02647 is a square end mill engineered for precision material removal in tight-tolerance machining applications. Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers hardness and heat resistance suited to cutting ferrous and hardened materials. The cutter measures 0.04 inches in diameter with a 0.2 inch length of cut, a 0.125 inch straight-cylindrical shank, and a 2.5 inch overall length. The 30-degree right-hand helix and four-flute spiral geometry promote chip evacuation and surface finish quality. This is a single-end, centercutting tool appropriate for vertical machining centers and manual mills.

This end mill is used in precision machining environments where small-diameter cutting is required, including mold making, die work, aerospace component finishing, and medical part production. The extended length type and 0.04 inch diameter make it well suited for reaching into narrow slots, pockets, and confined features where larger tooling cannot access. It runs right-hand cutting direction and is compatible with standard collet chucks accepting a 0.125 inch shank.

Key Features

• 0.04 inch cutting diameter with a diameter tolerance of +0.000 to -0.001 inches for consistent fit in precision programs
• AlTiN coating provides elevated heat and wear resistance for dry or high-speed cutting conditions
• Micrograin solid carbide substrate supports rigidity and edge retention at small diameters
• Four-flute, 30-degree right-hand spiral geometry balances chip clearance and finish quality
• Centercutting design allows plunge entry as well as peripheral and slot milling
• Straight-cylindrical 0.125 inch shank fits standard collet and end mill holders

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool for CNC machining centers and manual mills accepting a 0.125 inch straight-cylindrical shank with standard collet or end mill holder tooling.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the rated collet bore depth and torque the collet nut according to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut, especially at this diameter where deflection sensitivity is high.
