Htc 145-4093 Ball End Mill 3/32 in 4 Flute Solid Carbide

Product Description

The HTC 145-4093 is a solid carbide ball end mill engineered for both roughing and finishing operations in a single tool. Part of the Series 145 lineup, it features a 3/32 inch (0.0938 inch decimal) cutting diameter with a 3/8 inch length of cut and a 1/8 inch straight-cylindrical shank. The AlTiN (aluminum titanium nitride) PVD coating provides elevated hardness and thermal resistance, making this tool well-suited for high-speed cutting in ferrous and difficult-to-machine materials. Machinists and CNC operators install this end mill in standard milling machines and machining centers where compact tooling is required.

This end mill is designed for use in precision milling applications requiring a small-diameter ball nose profile. The 3/32 inch diameter makes it appropriate for detailed contour work, shallow cavity milling, and fine 3D profiling on ferrous alloys, hardened steels, and similar materials. Its standard-length geometry and 1-1/2 inch overall length suit it to setups where minimal overhang and rigidity are priorities. It is a single-end tool with right-hand cutting and right-hand spiral flutes, configured for conventional CNC milling setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN PVD coating improves heat resistance and extends tool life in ferrous applications
• 4-flute spiral design supports both roughing and finishing in a single pass
• Ball nose geometry with 0.0469 inch nose radius enables 3D contouring and profiling
• Right-hand cut, right-hand helix for standard CNC milling spindle compatibility
• Straight-cylindrical shank fits standard ER collets and end mill holders

Compatibility

Designed as an OEM-style replacement and direct-use solid carbide ball end mill for standard CNC milling machines and machining centers accepting a 1/8 inch straight-cylindrical shank.

Installation Notes

Installation is performed by machinists or CNC tooling technicians. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully and evenly in the collet or end mill holder and torque the retention nut according to the holder manufacturer's specifications. Inspect the tool edge under magnification before use and confirm runout is within acceptable limits for the application.
