Value Collection 720-1557 Square End Mill 1 in 2 Flute Hss

Product Description

The VALUE COLLECTION 720-1557 is a single-end square end mill designed for precision milling operations on aluminum and non-ferrous materials. Manufactured from M2 high speed steel with a bright uncoated finish, this tool delivers consistent cutting performance in machining environments where coating is not required. It features a 1-inch mill diameter, a 6-inch length of cut, and an extra-long 8.5-inch overall length, making it well suited for deep pocket milling and extended-reach applications. The 2-flute geometry and 37-degree right-hand helix promote efficient chip evacuation, reducing heat buildup when cutting softer metals.

This end mill is intended for use in manual and CNC vertical milling machines. Its extra-long length type and 1-inch shank diameter accommodate setups that require extended tool projection beyond a standard holder. The primary workpiece material designation is aluminum and non-ferrous, making it appropriate for production shops, tool rooms, and job shops that regularly machine aluminum alloys, brass, copper, and similar materials. It is sold as a single-end tool, meaning only one cutting end is present.

Key Features

• M2 high speed steel construction for durability in non-ferrous milling applications
• 6-inch length of cut supports deep pocket and slot milling operations
• Extra-long 8.5-inch overall length provides extended reach in deep setups
• 37-degree right-hand spiral flute promotes chip evacuation and reduces cutting forces
• Bright uncoated finish maintains dimensional accuracy without coating buildup
• Center-cutting capable, allowing plunge cutting as well as peripheral milling

Compatibility

Designed as a general-purpose replacement or production end mill for CNC and manual milling machines accepting a 1-inch straight shank, primarily intended for aluminum and non-ferrous workpiece materials.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before loading or unloading the tool. Secure the 1-inch shank in a compatible end mill holder or collet system, tightening to the holder manufacturer specifications. Verify runout with a dial indicator before beginning cuts to avoid premature tool wear or chatter.
