Sgs 33454 Roughing End Mill 1/4 in 3 Flute Solid Carbide

Product Description

The SGS 33454 is a solid carbide roughing end mill designed for aggressive material removal in milling operations. It features a 1/4 inch diameter with a 3-flute, coarse-pitch chipbreaker geometry that breaks chips into manageable pieces, reducing heat buildup and tool load during heavy cuts. A 0.02 inch corner radius adds edge strength at the cutting tip. The Titanium Diboride (TiB2) coating improves hardness and lubricity for extended tool life. This end mill is single-ended with right-hand cut and right-hand spiral flutes, and a maximum helix angle of 38 degrees. It is intended for use by machinists and tooling professionals in CNC and manual milling applications.

This roughing end mill suits applications where rapid stock removal is the priority before a finishing pass. The chipbreaker geometry makes it well suited for cutting ferrous and non-ferrous metals where chip control is critical. The 1/4 inch straight cylindrical shank with h6 tolerance fits standard collets and end mill holders. With a 1.25 inch length of cut and 3.5 inch overall length, it handles moderate-depth roughing passes in a variety of workpiece materials.

Key Features

• Chipbreaker geometry breaks chips for improved evacuation and reduced cutting forces
• Solid carbide construction provides rigidity and wear resistance
• Titanium Diboride (TiB2) coating for increased surface hardness and lubricity
• 0.02 inch corner radius strengthens the cutting edge and reduces chipping
• 38 degree maximum helix angle supports aggressive feed rates
• Center-cutting capable, allowing plunge entry into the workpiece
• Right-hand cut, right-hand spiral, single-end configuration

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill compatible with standard 1/4 inch straight-shank collets and end mill holders used in CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the milling machine spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the specified clamping depth in the collet or holder and verify runout before beginning cuts. Follow the machine manufacturer guidelines and applicable shop safety standards when setting feeds and speeds for roughing operations.
