Hertel C430S1875-C1 Roughing End Mill 3/16 in 4 Flute

Product Description

The HERTEL C430S1875-C1 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from micrograin solid carbide and coated with TiN (titanium nitride), this tool delivers hardness and wear resistance suited for high-speed roughing passes. The chipbreaker geometry on the cutting edges reduces cutting forces and helps break chips into manageable segments, which is especially important in deep-slot and side-milling applications. With a 3/16 inch diameter, 4 flutes, and a 3/8 inch length of cut, this end mill is sized for precision work in tight features and small-profile cuts. Licensed machinists, tool-and-die professionals, and CNC operators install and run this tool.

This end mill is suited for use in vertical machining centers, CNC knee mills, and manual milling machines where small-diameter roughing is required. The right-hand cut and right-hand flute direction make it compatible with standard spindle rotation. The centercutting capability allows plunge entry into the workpiece. At 2 inches overall length with a regular length type, this tool fits standard ER and end mill collet holders with a 3/16 inch bore. It is commonly applied in mold and die work, aerospace component machining, and general metalworking where chip control and tool longevity in roughing passes are priorities.

Key Features

• Micrograin solid carbide construction for hardness and heat resistance in roughing cuts
• TiN coating extends tool life and reduces friction at the cutting edge
• Chipbreaker geometry reduces cutting forces and breaks chips for better evacuation
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Right-hand cut and right-hand flute direction for standard CNC and manual mill spindle use
• 4-flute configuration balances chip load and surface finish during roughing passes

Compatibility

Designed for use in standard 3/16 inch end mill collet holders and ER collet chucks. Fits vertical machining centers and CNC milling machines with right-hand spindle rotation. No specific machine model compatibility was stated by the manufacturer for this part number.

Installation Notes

Installation is performed by a machinist or CNC operator. Power down and lock out the spindle before inserting or removing the end mill from the collet holder. Ensure the shank is fully seated and the collet is torqued to the tool holder manufacturer specification before running. Verify spindle speed and feed rate are set appropriately for the workpiece material and the 3/16 inch diameter before initiating a cut.
