Sgs 36143 Square End Mill 0.5 in 6 Flute Solid Carbide Series 57

Product Description

The SGS 36143 is a six-flute solid carbide square end mill engineered for aggressive material removal in hard and difficult-to-machine workpiece materials. It carries an AlTiN finish that improves heat resistance and extends tool life at elevated cutting speeds. The extra-long length-of-cut configuration gives machinists and tool-and-die technicians access to deeper pockets and extended reach applications where standard-length tools fall short. A 45-degree helix angle promotes efficient chip evacuation and smooth cutting action, reducing chatter in demanding cuts.

This end mill is suited for milling operations on hard materials in production and job-shop environments. Its centercutting geometry allows direct plunge entry without a pilot hole, making it practical for pocketing and profiling operations. The straight cylindrical shank and right-hand cut with right-hand flute configuration are compatible with standard ER and side-lock toolholders used on CNC machining centers and manual knee mills. It is installed by machinists, toolmakers, and CNC operators working in ferrous and hardened-steel applications.

Key Features

• Six-flute design increases feed rate capability and improves surface finish compared to four-flute tools
• AlTiN coating provides oxidation resistance and hardness at elevated cutting temperatures
• 45-degree helix angle promotes efficient chip flow and reduces cutting forces
• Centercutting geometry enables direct plunge milling without pre-drilling
• Extra-long length of cut at 1.09 inches accommodates deep-pocket and extended-reach applications
• Series 57 solid carbide construction maintains rigidity and edge integrity in hard-material applications

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 0.5 inch straight cylindrical shank with right-hand cut orientation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator following the machine tool manufacturer's toolholder torque and runout specifications. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Verify shank seating depth and runout with a dial indicator before initiating a cut. Refer to the cutting tool manufacturer's recommended speeds and feeds for hard materials when programming the toolpath.
