Titan Usa TC66512 Corner Radius End Mill 3/16 in 3 Flute

Product Description

The TITAN USA TC66512 is a solid carbide corner radius end mill designed for precise material removal in non-ferrous metals including aluminum, brass, and bronze. The cutter measures 3/16 inch (0.1875 inch) in diameter with a 0.0100 inch corner radius and a 3/4 inch length of cut. Three right-hand spiral flutes with a 45-degree high helix angle promote efficient chip evacuation and smooth finishes in softer, gummy materials. A ZrN (zirconium nitride) PVD coating increases surface hardness and reduces built-up edge. The centercutting geometry allows plunge entry, making it suitable for slot milling, profiling, and pocket operations. Machinists and CNC operators working in job shops or production environments are the primary users.

This end mill is suited for light-duty to medium roughing operations in non-ferrous metals such as aluminum, brass, and bronze. Its long-reach configuration, with a 3/4 inch reach length and 2.5 inch overall length, makes it appropriate for accessing deeper features or stepped pockets where a standard-length tool would not reach. The straight cylindrical shank mounts in standard toolholders used in vertical machining centers, milling machines, and CNC routers. The coarse pitch geometry is optimized for material removal rate in softer alloys.

Key Features

• 0.0100 inch corner radius reduces stress concentration at cutting edges and improves surface finish at part corners
• Solid carbide construction provides rigidity and wear resistance superior to high-speed steel in non-ferrous applications
• ZrN PVD coating lowers friction and resists built-up edge common when machining aluminum and brass
• 45-degree high helix angle improves chip flow and reduces cutting forces in softer materials
• Centercutting end allows direct plunge entry without a pre-drilled hole
• Single-end, three-flute design balances chip clearance with cutting edge count for non-ferrous roughing

Compatibility

Designed for use with standard straight-bore toolholders on vertical machining centers, CNC mills, and manual milling machines. Primary workpiece material classification is non-ferrous metal (Material Application Code: N), including aluminum, brass, and bronze.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Secure the straight cylindrical shank in a clean, properly sized collet or end mill holder to the toolholder manufacturer's recommended retention torque; confirm runout before cutting. Power down and lock out the spindle before tool changes. Inspect the corner radius and cutting edges for chips or wear before each use, as damage to the corner geometry will affect dimensional accuracy at part radii.
