Value Collection 720-1181 Square End Mill 1/2 in 2 Flute Hss

Product Description

The VALUE COLLECTION 720-1181 is a single-end square end mill designed for general-purpose milling operations in metalworking and machining applications. Manufactured from M2 high speed steel with a bright/uncoated finish, it delivers reliable performance in slotting, profiling, and peripheral milling. The tool features a 1/2 inch cutting diameter, a 1 inch length of cut, and a 4 inch overall length. Two right-hand spiral flutes with a 30-degree helix angle provide efficient chip evacuation and smooth cutting action. This end mill is center-cutting, allowing plunge entry, and is suited for use in manual mills, CNC machining centers, and knee mills.

This end mill is intended for use in general metalworking environments including job shops, maintenance facilities, and production floors. The 1/2 inch shank diameter fits standard ER collet chucks and end mill holders commonly found in both manual and CNC setups. The regular-length geometry and 2-1/4 inch reach length make it appropriate for standard-depth slots and profiles without excessive overhang. It is well-suited for cutting ferrous and non-ferrous metals where a bright uncoated HSS tool is preferred over coated carbide alternatives.

Key Features

• M2 high speed steel construction for toughness and wear resistance in general milling
• Bright/uncoated finish suitable for a wide range of workpiece materials
• Center-cutting design allows direct plunge entry into the workpiece
• 30-degree right-hand helix promotes efficient chip removal and reduced heat buildup
• Two flutes provide clearance for chip evacuation in slotting and pocketing operations
• Regular-length classification with 2-1/4 inch reach for standard-depth cuts

Compatibility

Designed as a standard fractional-inch end mill for use in 1/2 inch end mill holders, ER collet chucks, and Weldon-style tool holders compatible with 1/2 inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist following the tool holder manufacturer's torque and runout specifications. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Verify shank seating depth meets tool holder minimums to prevent pullout under cutting loads. Do not exceed the recommended depth of cut or feed rate for M2 HSS tooling in the material being machined.
