Value Collection 720-8250 Square End Mill 0.9843 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-8250 is a single-end square end mill designed for general-purpose milling operations in metal fabrication and machining environments. It measures 0.9843 inches in diameter with a 2-inch length of cut and a 1-inch shank diameter, giving it a rigid setup in standard tool holders. The overall length is 4.5 inches. Constructed from M2 high speed steel with a bright uncoated finish, this end mill handles a range of ferrous and non-ferrous materials where carbide tooling is not required. Machinists and tool-and-die technicians are the primary users.

This end mill is suited for manual mills, CNC machining centers, and knee mills in job shop, maintenance, and light production environments. The 4-flute spiral configuration with a 30-degree helix angle provides a balance of chip evacuation and surface finish on steel, aluminum, and similar workpiece materials. The centercutting design allows plunge entry without a pre-drilled pilot hole, adding flexibility to the machining process. It is a single-end tool, meaning the cutting geometry is on one end only.

Key Features

• 0.9843-inch cutting diameter with 2-inch length of cut for deep slot and peripheral milling
• 4 spiral flutes at a 30-degree helix angle for balanced chip load and finish quality
• M2 high speed steel construction suitable for a broad range of workpiece materials
• Bright uncoated finish — no coating buildup to affect dimensional tolerances
• Centercutting geometry allows direct plunge entry into the workpiece
• Right-hand cut and right-hand flute direction for standard spindle rotation

Compatibility

Designed as a standard-shank single-end square end mill with a 1-inch shank diameter, compatible with tool holders and collet chucks sized for 1-inch round shanks on manual or CNC milling machines.

Installation Notes

Installation is performed by a machinist or tooling technician. Power down and lock out the spindle before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention fastener to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a cut, and confirm spindle direction matches the right-hand cut geometry of this tool.
