Value Collection 849-0187 Square End Mill 3/16 in 4 Flute Hss

Product Description

The VALUE COLLECTION 849-0187 is a double-end, 4-flute square end mill designed for general-purpose milling operations in metal fabrication and machine shop environments. Built from high speed steel (HSS), it carries a bright/uncoated finish and features a 3/16 inch cutting diameter with a 9/32 inch length of cut. The straight shank matches the 3/16 inch cutting diameter for direct collet or end mill holder mounting. With a stub-length profile and 2 inch overall length, this tool suits applications where rigidity and compact reach are priorities. Right-hand cutting and right-hand spiral flutes are standard. It is installed and operated by machinists and toolroom technicians on manual mills and CNC machining centers.

This end mill is suited for slotting, profiling, and peripheral milling in materials compatible with uncoated HSS tooling, such as low-carbon steels, aluminum, brass, and plastics. The stub-length designation means reduced overhang and improved rigidity compared to standard or long-length end mills, making it appropriate for shallow-depth cuts where chatter control matters. The double-end design allows the operator to index to the second cutting end when the first end reaches wear limits, extending useful tool life per unit.

Key Features

• Double-end design with two usable cutting ends for extended tool life
• 4-flute spiral configuration with right-hand cut and right-hand flute direction
• High speed steel construction suitable for ferrous and non-ferrous materials
• Bright/uncoated finish — compatible with cutting oils and general-purpose coolants applied externally
• 30-degree helix angle for balanced chip evacuation and surface finish
• Stub-length profile improves rigidity in shallow milling applications
• Not center-cutting — requires a pre-drilled or pre-bored entry point for plunge operations

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for milling machines accepting a 3/16 inch straight-shank end mill in standard collet chucks or end mill holders.

Installation Notes

This end mill is installed by machinists using a compatible collet, end mill holder, or set-screw adapter sized for a 3/16 inch shank. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify collet and holder runout before use, as excessive runout accelerates edge wear at this diameter. This tool is not center-cutting and cannot be used for direct plunge entry without a pre-existing bore or slot.
