Value Collection 720-1439 Ball End Mill 1-1/4 in 2 Flute Hss

Product Description

The VALUE COLLECTION 720-1439 is a single-end ball end mill designed for contour milling, slotting, and profiling operations in ferrous and non-ferrous materials. Manufactured from M2 high speed steel with a bright, uncoated finish, it measures 1.250 inches in diameter with a 2.500-inch length of cut and a 5.000-inch overall length. The 2-flute geometry promotes chip evacuation in applications where material tends to pack, making it a practical choice for general-purpose machining work. Machinists and tooling professionals install this end mill in vertical machining centers, knee mills, and CNC milling setups where ball-nose profile cuts are required.

This ball end mill is suited for die and mold work, radius slotting, and 3D contouring on a wide range of workpiece materials. The right-hand cutting and right-hand spiral flute direction is standard for conventional milling setups. The 1.250-inch shank diameter matches the mill diameter, providing a rigid fit in standard collets and end mill holders of the same bore size. It is sold as a single-end tool intended for direct chuck or collet mounting without tool-holder adapters beyond standard bore compatibility.

Key Features

• M2 high speed steel construction provides toughness and wear resistance in general-purpose milling
• Ball-nose geometry enables 3D contouring, radius slotting, and profile milling in a single tool
• 2-flute spiral design promotes chip clearance during slotting and pocketing operations
• Right-hand cut and right-hand flute direction compatible with standard spindle rotation
• Bright, uncoated finish — suitable for use with cutting fluid or dry in appropriate materials
• 1.250-inch shank diameter provides rigid mounting in matched collets and end mill holders

Compatibility

Designed as a standard-shank single-end ball end mill for use in vertical machining centers, knee mills, and CNC milling machines equipped with collets or end mill holders bored to 1.250 inches.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling guidelines. Ensure the spindle is fully powered down and locked out before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention mechanism per the holder manufacturer's specification. Verify runout with a dial indicator before initiating a cut, as excessive runout accelerates wear on HSS tooling.
