Sgs 36712 Corner Radius End Mill 3/4 in 4 Flute Carbide

Product Description

The SGS 36712 is a solid carbide corner radius end mill designed for high-performance material removal and finishing in demanding machining applications. Built to the ZPCR series standard, it features a 3/4 inch cutting diameter, a 1-1/2 inch length of cut, and a 0.0300 inch corner radius that reduces stress concentrations at the tool tip and workpiece corner. The variable helix geometry — ranging from 35 to 38 degrees — helps break up harmonics and chatter during aggressive cuts. A TX coating adds surface hardness and heat resistance, extending tool life in difficult materials. This end mill is suited for machinists and CNC operators working in production or job-shop environments.

The SGS 36712 is engineered for cutting steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Its single-end, right-hand cut, right-hand flute configuration is standard for use in vertical and horizontal machining centers. The Weldon flat shank provides positive drive retention in compatible end mill toolholders, making it appropriate for high-feed and high-speed toolpaths where pullout is a concern. The short length type keeps deflection low during full-depth slotting or profiling passes.

Key Features

• 0.0300 inch corner radius with a tolerance of -0.0020 to 0.0000 inches for consistent edge geometry
• Variable helix (35 to 38 degrees) and variable index reduce chatter and improve surface finish
• TX coating provides thermal and wear resistance for extended tool life in ferrous and hard materials
• Micrograin solid carbide construction for rigidity and edge retention
• Weldon flat shank with h6 tolerance for secure toolholder engagement
• Suitable for both roughing and finishing material removal strategies

Compatibility

Designed for use with standard end mill toolholders that accept a 3/4 inch Weldon flat shank. Intended for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials as identified by material codes P, M, K, S, and H.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before installing or removing the end mill. Seat the Weldon flat fully against the toolholder setscrew and torque to the toolholder manufacturer specification. Verify runout after clamping before initiating any cutting program.
