Sgs 32669 Square End Mill 3/4 in 5 Flute Solid Carbide Altin

Product Description

The SGS 32669 is a solid carbide square end mill designed for high-performance milling in demanding production environments. Built from micrograin carbide and coated with AlTiN, it handles elevated cutting temperatures and extends tool life in hard and abrasive workpiece materials. The 5-flute configuration with a 45-degree helix angle improves chip evacuation and surface finish at higher feed rates. At 3/4 inches in diameter with a 1-5/8 inch length of cut and 4 inch overall length, this is a right-hand cut, right-hand flute tool suited for finishing and semi-finishing passes. It is installed and operated by machinists and tool-and-die professionals in CNC milling applications.

This end mill is engineered for use in milling ISO material groups H, K, M, P, and S, which include hardened steels, cast irons, stainless steels, carbon steels, and superalloys. The variable index tooth geometry reduces harmonic chatter during cutting, making it well suited for deep-pocket profiling, shoulder milling, and slot work on both vertical and horizontal machining centers. It accepts standard ER collet and set-screw toolholders with a straight cylindrical shank.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN coating provides thermal protection and extended tool life in dry or near-dry cutting
• 45-degree helix angle promotes aggressive chip evacuation and improved surface finish
• 5-flute, variable index design reduces chatter and vibration at high feed rates
• Right-hand cut and right-hand spiral flute geometry for standard CNC milling setups
• Non-centercutting design — not intended for direct plunge operations

Compatibility

Suitable for milling ISO workpiece material groups H, K, M, P, and S, including hardened steels, cast irons, stainless steels, carbon and alloy steels, and superalloys. Part of the SGS Series 55 end mill line.

Installation Notes

Install in a compatible ER collet chuck or set-screw toolholder sized for a 3/4 inch straight cylindrical shank. Verify runout at the toolholder before beginning cuts — excessive runout accelerates edge wear on carbide tooling. This tool is not centercutting; use a ramping or helical entry strategy rather than direct plunge milling. Follow machine tool manufacturer torque specifications for collet nuts and toolholder retention fasteners.
