Sgs 33393 Roughing End Mill 1/4 Inch 3 Flute Solid Carbide

Product Description

The SGS 33393 is a solid carbide roughing end mill designed for aggressive material removal in milling operations. Built with 3 flutes, a coarse pitch, and a chipbreaker geometry, it breaks chips into short segments to reduce heat buildup and prevent recutting. The 0.02 inch corner radius adds edge strength during heavy roughing cuts. With a 38-degree maximum helix angle and right-hand flute direction, this end mill is optimized for efficient chip evacuation and stable cutting. It is used by machinists and tool-and-die professionals on CNC mills and machining centers where high metal removal rates are the priority.

This end mill suits roughing passes on a wide range of materials in both job shop and production environments. The 1/4 inch diameter and 1 inch length of cut make it well suited for slotting, profiling, and peripheral milling in tighter workpiece features. The straight-cylindrical shank with h6 tolerance ensures consistent runout when seated in standard collet chucks or end mill holders. It is a single-end tool, so when the cutting edge is worn it is replaced rather than flipped.

Key Features

• Chipbreaker flute geometry reduces chip load and heat during roughing passes
• Solid carbide construction provides rigidity and wear resistance compared to HSS tooling
• 3-flute, coarse-pitch design balances chip room with cutting edge count
• 0.02 inch corner radius strengthens the cutting edge against chipping
• 38-degree maximum helix angle promotes aggressive chip evacuation
• Center-cutting capability allows plunge entry without a pre-drilled hole
• Bright/uncoated finish suitable for use as-ground or with cutting fluid

Compatibility

Designed as a standard 1/4 inch straight-cylindrical shank roughing end mill compatible with collet chucks, shrink-fit holders, and end mill holders that accept 1/4 inch shank tooling on CNC or manual milling machines.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the tool is secured to the correct torque specification for the holder type being used before beginning any cut. Confirm shank seating depth meets the holder manufacturer minimum engagement requirement to prevent tool pullout under load. Use appropriate cutting fluid or air blast as recommended for the workpiece material to extend tool life.
