Hertel 750651 Square End Mill 3/16 in 2 Flute Carbide Tin

Product Description

The HERTEL 750651 is a solid carbide square end mill designed for precision milling operations in metal, composite, and hard material applications. With a 3/16 inch cutting diameter and a 1-1/8 inch length of cut, this single-end tool delivers consistent performance in slotting, profiling, and contouring work. The 30-degree helix angle promotes efficient chip evacuation, while the Titanium Nitride (TiN) coating extends tool life by reducing friction and wear at the cutting edge. Built from micrograin carbide stock, it holds tighter tolerances and resists chipping better than standard carbide grades. Machinists and tool-and-die professionals are the primary users of this end mill.

This end mill is suited for use in CNC machining centers, manual mills, and high-speed spindle applications where a small-diameter finishing or roughing tool is needed. The 3/16 inch shank diameter matches the cutting diameter, making it compatible with standard collet systems and toolholders set up for that bore size. Right-hand cutting and right-hand flute direction make it the conventional choice for standard spindle setups. It is commonly used in job shops, toolrooms, and production environments handling ferrous and non-ferrous workpieces.

Key Features

• 3/16 inch cutting diameter with 1-1/8 inch length of cut for deep slot and profile work in small geometries
• 2-flute design promotes chip clearance in tighter cuts and softer material applications
• Titanium Nitride (TiN) coating reduces friction and extends cutting edge life
• Micrograin solid carbide construction for improved edge retention and fracture resistance
• 30-degree helix angle aids chip evacuation and improves surface finish
• Right-hand cut, right-hand spiral, centercutting - compatible with standard CNC and manual mill setups

Compatibility

Designed for use in any standard milling setup accepting a 3/16 inch shank diameter, including ER collet systems and precision toolholders commonly found in CNC machining centers and manual knee mills.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a safe lockout state. Ensure the collet or toolholder bore is clean and free of debris before seating the shank. Verify runout with a dial indicator after clamping to protect the cutting edge and workpiece accuracy. Follow the machine manufacturer and tooling supplier guidelines for appropriate feed rates, speeds, and depth of cut for the workpiece material.
