Sgs 33404 Roughing End Mill 3/8 in 3 Flute Solid Carbide

Product Description

The SGS 33404 is a solid carbide roughing end mill designed for aggressive material removal in milling applications. It features a 3/8-inch diameter, three flutes with a coarse pitch chipbreaker geometry, and a 0.02-inch corner radius. The chipbreaker design breaks chips into short segments to reduce cutting forces and heat buildup, making this tool effective in demanding roughing passes. The 38-degree maximum helix angle promotes efficient chip evacuation. This tool is installed by machinists and tool-and-die professionals operating CNC machining centers or manual mills requiring high-performance roughing capability.

The SGS 33404 is suited for roughing operations in ferrous and non-ferrous materials where high material removal rates are required. The bright/uncoated finish makes it appropriate for applications where coating compatibility with the workpiece material must be considered. With a 2-inch length of cut and 4-inch overall length, it handles standard depth applications in vertical and horizontal milling setups. Single-end, right-hand cutting and right-hand flute direction are standard for conventional CNC and manual mill spindle configurations.

Key Features

• Solid carbide construction for rigidity and wear resistance in roughing cuts
• Chipbreaker geometry reduces cutting forces and promotes chip control
• 0.02-inch corner radius adds edge strength and reduces corner chipping
• 38-degree maximum helix angle supports efficient chip evacuation
• Centercutting design allows plunge entry into the workpiece
• Straight-cylindrical shank with h6 tolerance for consistent tool holder fitment

Compatibility

Designed as a standard roughing end mill for use in tool holders accepting a 3/8-inch straight-cylindrical shank with h6 tolerance, compatible with CNC machining centers and manual mills using ER collets, shrink-fit holders, or set-screw style end mill holders of the appropriate bore size.

Installation Notes

Installation should be performed by a qualified machinist following the tool holder manufacturer's clamping specifications. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Confirm the tool holder bore and collet size match the 3/8-inch shank diameter before seating the tool. Proper overhang length should be minimized to maintain rigidity and reduce vibration during roughing passes.
