Value Collection 934-000-119 Square End Mill Hss

Product Description

The VALUE COLLECTION 934-000-119 is a single-end square end mill designed for precision milling operations in metal and composite materials. Manufactured from high speed steel (HSS), this end mill features a 0.055-inch diameter cutting edge with a 0.165-inch length of cut and a 40-degree helix angle that promotes efficient chip evacuation and clean edge finish. With two flutes and a right-hand cutting and flute direction, it is suited for slotting, profiling, and light plunge work in small-bore and tight-tolerance applications. Machinists and tool and die professionals reach for this geometry when fine detail work demands a small-diameter, bright uncoated tool.

This end mill is appropriate for use in manual mills, CNC machining centers, and precision die-sinking applications where a small-diameter HSS tool is required. The 3/16-inch straight shank fits standard collet chucks and end mill holders commonly found in toolroom and production environments. Its regular-length profile and 1.5-inch overall length keep runout manageable at small diameters, making it a practical choice for detail milling in soft steels, aluminum, brass, and plastics.

Key Features

• 0.055-inch cutting diameter with -0.0010 to +0.0000 inch tolerance for tight-fit applications
• High speed steel construction provides toughness and re-sharpenability
• 40-degree helix angle promotes efficient chip flow and reduces heat buildup
• 2-flute geometry allows adequate chip clearance in slotting and profiling cuts
• Center-cutting design permits direct plunge entry without a pre-drilled pilot hole
• Bright/uncoated finish suitable for use with or without cutting fluid

Compatibility

Designed as a standard-shank replacement or stock end mill for toolroom, die, and production machining applications requiring a 0.055-inch diameter HSS square end mill with a 3/16-inch straight shank.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing end mills. Seat the 3/16-inch shank fully into a clean, burr-free collet or end mill holder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning production cuts, as runout is especially critical at small diameters like 0.055 inch.
