Hertel 750319 Square End Mill 0.5in 3 Flute Solid Carbide

Product Description

The HERTEL 750319 is a solid carbide square end mill designed for precision milling operations in metal cutting environments. Built from micrograin solid carbide and finished with an AlTiN (aluminum titanium nitride) coating, this tool delivers extended tool life and heat resistance at elevated cutting speeds. It features a 0.5 inch cutting diameter, a 1 inch length of cut, and a 30-degree helix angle that promotes efficient chip evacuation. The three-flute configuration balances chip clearance with cutting edge strength, making it a reliable choice for slotting, profiling, and peripheral milling. Licensed machinists and tool-room operators are the primary users of this end mill.

This end mill is suited for use on CNC machining centers and manual mills in both production and job-shop environments. The centercutting geometry allows direct plunge entry into the workpiece, expanding its use in pocketing and plunge milling operations. The right-hand cutting direction is standard for conventional milling machine spindle rotation. The 0.5 inch shank diameter fits standard ER and side-lock toolholders common across most machining setups. It is appropriate for milling ferrous and non-ferrous alloys where AlTiN coating performance is advantageous.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN finish provides high-temperature oxidation resistance and extended tool life
• 30-degree helix angle promotes efficient chip evacuation during slotting and profiling
• Centercutting design enables direct plunge milling without a pre-drilled entry hole
• Three-flute geometry balances chip clearance with cutting surface contact
• Right-hand cut with standard 0.5 inch shank for broad toolholder compatibility

Compatibility

Designed for use with standard 0.5 inch bore toolholders including ER collet chucks and side-lock holders on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping torque and runout specifications. Ensure the spindle is fully stopped and the machine is in an energy-isolated state before inserting or removing the end mill. Confirm proper tool stick-out and minimize overhang to reduce deflection and chatter. Always verify that the cutting direction and spindle rotation match the right-hand configuration of this tool before initiating a cut.
