Titan Usa TC10503 Square End Mill 0.0469 in 4 Flute Carbide

Product Description

The TITAN USA TC10503 is a 4-flute solid carbide square end mill designed for precision milling in metalworking and machining applications. With a cutting diameter of 0.0469 inches (3/64 inch) and a length of cut of 0.125 inches, this tool handles fine detail work where dimensional accuracy is critical. The micrograin carbide substrate provides the hardness and edge retention needed for ferrous and non-ferrous materials. A 30-degree helix angle promotes efficient chip evacuation, reducing heat buildup at the cutting edge. The bright, uncoated finish keeps the tool at its ground diameter without coating thickness variation. This end mill is intended for use by machinists and CNC operators working in job shops, tool rooms, and production environments.

This end mill suits applications requiring tight tolerances in small-feature milling, slotting, and profiling. The 0.125-inch shank diameter fits standard ER collets and small end mill holders common in CNC machining centers and manual mills. The 1.5-inch overall length keeps the tool stiff enough to resist deflection at this small diameter. Centercutting geometry allows direct plunge entry as well as conventional peripheral and slot milling.

Key Features

• 0.0469 inches (3/64 inch) cutting diameter for fine-detail and small-feature work
• 4-flute design increases feed rate potential versus 2-flute geometry
• Micrograin solid carbide construction for hardness and edge retention
• 30-degree helix angle promotes chip evacuation and reduces cutting heat
• Centercutting capable — supports plunge, slot, and peripheral milling
• Bright/uncoated finish maintains true ground diameter tolerance

Compatibility

Designed as a standard replacement or stocked cutting tool for CNC machining centers, knee mills, and manual milling machines accepting a 0.125-inch shank through ER collet systems or small-bore end mill holders.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the spindle fully stopped and machine power locked out before tool changes. Seat the 0.125-inch shank fully into the collet or holder to the minimum recommended grip depth to prevent pullout under cutting loads. At this diameter, tool runout must be minimized — check TIR with a dial indicator after clamping. Follow shop-standard feeds and speeds for the workpiece material and do not exceed the rated length of cut of 0.125 inches to avoid tool deflection or breakage.
