Sgs 33350 Corner Radius End Mill 7/16 in 3 Flute Altin

Product Description

The SGS 33350 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining applications. It features a 7/16 inch (0.4375 inch) diameter with a 0.02 inch corner radius that protects the cutting edge and reduces chipping at the tool tip. The 1-1/8 inch length of cut (LOC) and 2-3/4 inch overall length (OAL) make it well suited for standard-depth milling operations. An AlTiN coating — marketed as Ti-NAMITE-A by SGS — provides thermal resistance and wear protection during high-speed cutting. The variable helix and coarse pitch geometry aid in chip evacuation and vibration reduction. This tool is installed and operated by machinists and CNC programmers working in production and job-shop environments.

The SGS 33350 is intended for roughing and finishing operations on steel, stainless steel, cast iron, superalloys, and titanium. It also handles hard materials as a secondary application. The single-end, right-hand cutting, right-hand flute design is compatible with standard end mill toolholders. The centercutting designation in the raw data is noted as No, meaning this tool is not intended for direct plunge entry. It is best applied in profile milling, slotting within its cut depth range, and ramping or helical interpolation entries. The straight cylindrical shank with h6 tolerance fits standard precision collet chucks and shrink-fit holders.

Key Features

• 0.02 inch corner radius with a tolerance of -0.0020 to 0.0000 inches protects the cutting edge and improves tool life at corners
• AlTiN coating (Ti-NAMITE-A) delivers high thermal hardness for cutting steel, stainless steel, and superalloys
• Variable helix geometry reduces harmonic vibration and improves surface finish during aggressive cuts
• Micrograin solid carbide substrate provides rigidity and resistance to wear in hard and abrasive materials
• 3-flute, right-hand spiral design balances chip clearance with cutting edge strength for roughing passes
• Straight cylindrical shank with h6 shank diameter tolerance ensures accurate and repeatable tool holding

Compatibility

Designed for use with standard end mill toolholders. Compatible primary workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium. Hard materials are listed as a secondary workpiece application. UNSPSC code 27112803.

Installation Notes

This tool is installed and operated by machinists and CNC machine operators. Before changing tooling, confirm the spindle is fully stopped and the machine is in a safe state per shop lockout/tagout procedures. Seat the shank fully into the toolholder and torque the retention mechanism to the toolholder manufacturer specification. Because this end mill is not centercutting, avoid direct axial plunge — use ramping, helical entry, or pre-drilled starting holes instead.
