Sgs 32708 Square End Mill 3/8 Inch 3 Flute Solid Carbide

Product Description

The SGS 32708 is a solid carbide square end mill designed for precision milling of non-ferrous metals and similar materials. Built on the Series 43L long-reach platform, it features a 3/8 inch cutting diameter, a 1/2 inch length of cut, and a 4 inch overall length that gives technicians extended access in deeper cavity work. The micrograin carbide construction supports tighter tolerances and longer tool life compared to standard HSS tooling. With a 38-degree helix angle and three right-hand spiral flutes, it produces efficient chip evacuation and a clean finish on aluminum, copper, and other non-ferrous stock. It is center-cutting, allowing direct plunge entry without a pre-drilled hole.

This end mill suits CNC machining centers and manual mills in job shop, production, and maintenance environments where long-reach access is required. The straight-cylindrical shank seats securely in standard collet chucks and end mill holders. The extended neck reach of 2.125 inches makes it well suited for slotting, profiling, and pocket milling in applications where standard-length tools cannot reach the workpiece safely. It is primarily intended for non-ferrous metal stock but performs in plastics and composite materials with appropriate feeds and speeds.

Key Features

• Solid micrograin carbide construction for tight tolerances and extended tool life
• 38-degree helix angle promotes aggressive chip evacuation in non-ferrous materials
• Center-cutting geometry allows direct plunge milling without a pilot hole
• Long Series 43L with 2.125 inch neck reach for deep-cavity and extended-reach applications
• Right-hand cut, right-hand flute with spiral flute profile for smooth material removal
• Uncoated finish suitable for non-ferrous metals where coating adhesion is not required

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC and manual milling setups using 3/8 inch collet chucks or end mill holders compatible with a straight-cylindrical shank. SGS Series 43L long-reach geometry. Primary workpiece material code N (non-ferrous metals).

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the collet or holder to the recommended grip depth and torque the retention mechanism per the tool holder manufacturer specification. Inspect the cutting edges for chips or damage before each use and verify runout with a dial indicator before beginning a new operation.
