Htc 200-4500 Square End Mill 1/2 in 4 Flute Solid Carbide

Product Description

The HTC 200-4500 is a double-end, square-profile solid carbide end mill designed for precision milling in metalworking and machining applications. With a 1/2 inch mill diameter, 5/8 inch length of cut, and four right-hand helical flutes, this tool delivers clean, accurate results in ferrous and non-ferrous materials. The AlTiN (aluminum titanium nitride) coating increases surface hardness and thermal resistance, extending tool life under high-speed cutting conditions. At 3 inches overall length with a 1/2 inch square shank, the 200-4500 fits standard toolholders found in most vertical machining centers and CNC mills. The stub length profile adds rigidity and minimizes deflection in tight setups.

The 200-4500 is suited for slot milling, peripheral milling, and profiling operations in job shop, production, and tool-and-die environments. Its double-end design provides two usable cutting ends, reducing per-cut tooling cost in high-volume operations. This end mill is a fit for use in CNC machining centers, manual knee mills, and benchtop milling machines where a 1/2 inch collet or end mill holder is used. It is not center-cutting, so it is not intended for direct plunge operations without a pre-drilled entry point.

Key Features

• Double-end design provides two cutting ends from a single tool
• AlTiN coating improves heat resistance and extends tool life in ferrous materials
• Four right-hand helical flutes for efficient chip evacuation and smooth surface finish
• Solid carbide construction for rigidity and wear resistance over high-speed steel alternatives
• Stub length profile reduces deflection in tight or shallow setups
• Right-hand cutting direction compatible with standard CNC and manual mill spindle rotation

Compatibility

Designed as an OEM-style replacement and standard tooling option for milling machines accepting a 1/2 inch shank end mill in a collet chuck or end mill holder. Part of the HTC Series 200 end mill line.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator familiar with toolholder torque requirements and runout specifications. Secure the shank fully in a collet or end mill holder, ensuring the tool does not bottom out against the drawbar or holder seat. Confirm spindle direction is set to right-hand rotation before engaging the cut. This tool is not center-cutting - always use a pre-drilled entry point or ramp-in strategy when plunging into material.
