Sgs 33352 Corner Radius End Mill 5/8 in 3 Flute Altin Carbide

Product Description

The SGS 33352 is a solid carbide corner radius end mill designed for high-performance metal removal in demanding machining environments. Built to Series 33CR specifications, it features a 5/8-inch diameter, a 1-1/2-inch length of cut, and a 0.04-inch corner radius that reduces stress concentrations at the cut edge and extends tool life. The variable helix geometry disrupts harmonic chatter, allowing for more aggressive feed rates and smoother finishes. An AlTiN coating, marketed under SGS's Ti-NAMITE-A designation, provides thermal resistance and oxidation protection at elevated cutting temperatures. This tool is installed by machinists and CNC operators working in job shops, production facilities, and aerospace manufacturing settings.

This end mill is engineered for roughing operations on steel, stainless steel, cast iron, superalloys, and titanium, and is rated for secondary use on hard materials. The coarse pitch flute geometry promotes efficient chip evacuation in these tough materials. The straight-cylindrical shank fits standard end mill holders and is sized at 5/8 inch with an h6 shank diameter tolerance for a secure, repeatable grip in the holder. Overall length is 3-1/2 inches, making it well-suited for standard reach roughing applications where rigidity is a priority.

Key Features

• Variable helix design reduces chatter and improves surface finish during roughing passes
• AlTiN (Ti-NAMITE-A) coating provides high-temperature oxidation resistance for extended tool life in ferrous and superalloy cutting
• 0.04-inch corner radius reduces edge chipping and distributes cutting forces across the tool corner
• Micrograin solid carbide substrate delivers hardness and wear resistance across difficult workpiece materials
• Right-hand cut, right-hand flute, single-end configuration for standard CNC milling setups
• Centercutting capability is not present on this tool — plunge milling requires a pilot hole or ramp entry

Compatibility

Designed for use with standard end mill holders accepting a 5/8-inch straight-cylindrical shank. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium. Rated for secondary use on hard materials.

Installation Notes

Install in a compatible end mill holder and torque the set screw or collet according to the holder manufacturer's specifications. Verify runout at the cutting diameter before beginning the operation, as excessive runout accelerates wear on a corner radius tool. This tool is not centercutting — do not plunge directly into solid material; use a ramping or helical entry path. Confirm that spindle speed and feed rate are appropriate for the workpiece material and depth of cut before engaging the cut.
