Sgs 34521 Square End Mill 5/8 in 2 Flute Solid Carbide

Product Description

The SGS 34521 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. It features a 5/8 inch cutting diameter, a 1-5/8 inch length of cut, and a 3-3/4 inch overall length, making it suited for stub-length applications where rigidity is a priority. The 45-degree helix angle with two right-hand spiral flutes promotes efficient chip evacuation and smooth cutting action. Centercutting capability allows for plunge entry directly into the workpiece. This tool is installed and operated by machinists and CNC programmers working with non-ferrous metals and similar materials.

The SGS 34521 is intended for milling non-ferrous metals including aluminum, brass, copper, and similar materials classified under workpiece material code N. The stub length and 5/8 inch Weldon flat shank provide excellent tool stability in collet and end mill holders. It is well suited for peripheral milling, slotting, and plunge operations on vertical machining centers and manual knee mills where a short, rigid tool setup is preferred.

Key Features

• Solid carbide construction for superior hardness and wear resistance compared to HSS
• 45-degree helix angle promotes efficient chip flow and reduced cutting forces
• Centercutting design allows direct plunge entry into the workpiece
• Right-hand cut and right-hand flute configuration for standard spindle rotation
• Weldon flat shank for positive tool retention in end mill holders
• Stub length type for maximum rigidity in tight setups

Compatibility

Designed as a Series 44 solid carbide square end mill optimized for non-ferrous metal machining applications with standard 5/8 inch end mill holders or collet systems accepting a Weldon flat shank.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling safety procedures. Ensure the machine spindle is fully powered down and locked out before installing or removing the end mill. Seat the Weldon flat shank securely against the set screw in the holder to prevent axial pull-out during cutting. Verify runout with a dial indicator after tooling changes to confirm proper seating before beginning operations.
