Hertel 750430 Square End Mill 5/32 in 4 Flute Solid Carbide

Product Description

The HERTEL 750430 is a solid carbide square end mill designed for precision milling operations in metal, alloy, and composite materials. Built from micrograin carbide, it offers the hardness and edge retention needed for high-speed cutting in ferrous and non-ferrous applications. The 4-flute, right-hand spiral geometry with a 30-degree helix angle balances chip evacuation with surface finish quality. At 5/32 inches (0.1563 inches) in diameter with a 3/4 inch length of cut, this is a small-diameter tool suited for fine detail work, slot milling, and contour profiling on CNC machining centers and manual mills.

This end mill fits standard production and tool room environments where small-diameter, single-end carbide tooling is required. It is center-cutting, allowing direct plunge entry into workpieces without pre-drilling. The regular length classification and 2-inch overall length make it suitable for shallow-to-moderate depth work where rigidity is a priority. Machinists, tool-and-die makers, and CNC operators working on precision components will find this tool appropriate for finishing passes and tight-tolerance slot work. The bright uncoated finish is compatible with a wide range of cutting fluids and is suitable for applications where coating interaction with the workpiece material is a concern.

Key Features

• Micrograin solid carbide construction for high hardness and extended tool life
• 4-flute right-hand spiral design with 30-degree helix angle for balanced chip flow and finish quality
• Center-cutting capability allows direct plunge entry without a pilot hole
• 5/32 inch (0.1563 inches) diameter with 3/4 inch length of cut for fine detail and slot milling
• Bright uncoated finish compatible with a broad range of workpiece materials and cutting fluids
• Single-end configuration; 3/16 inch shank diameter fits standard collets and end mill holders

Compatibility

Designed as a standard single-end square end mill for use in CNC machining centers, vertical mills, and manual milling machines accepting a 3/16 inch shank diameter collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully and evenly in the collet or holder and torque the retention mechanism to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as small-diameter carbide tools are sensitive to deflection and improper seating.
