Value Collection 840-0187 Square End Mill 3/16in 2 Flute Hss

Product Description

The VALUE COLLECTION 840-0187 is a double-end, two-flute square end mill designed for general-purpose milling operations in machine shops and manufacturing environments. Built from high speed steel (HSS) with a bright/uncoated finish, it measures 3/16 inches in diameter with a 1/2-inch length of cut and a 2-1/4-inch overall length. The 30-degree helix angle and right-hand spiral flutes promote efficient chip evacuation in a wide range of work materials. Center-cutting geometry allows plunge entry as well as conventional peripheral milling. This tool is typically installed and operated by machinists and CNC or manual mill operators.

The 840-0187 is suited for light to medium-duty milling tasks including slotting, profiling, and contouring in ferrous and non-ferrous materials. Its small 3/16-inch diameter makes it well matched to detail work, narrow slots, and fine-feature machining on knee mills, CNC machining centers, and benchtop milling machines. The double-end design provides two usable cutting ends, extending tool life between replacements. The straight 3/16-inch shank fits standard collets and end mill holders sized for that bore.

Key Features

• Double-end design delivers two cutting ends per tool
• High speed steel construction handles a broad range of work materials
• 30-degree right-hand helix promotes smooth chip flow and reduced chatter
• Center-cutting capable — supports direct plunge entry
• Bright/uncoated finish suitable for use with or without cutting fluid

Compatibility

Designed as a standard fractional-inch square end mill for use in any milling machine or machining center equipped with a collet, end mill holder, or chuck accepting a 3/16-inch straight shank.

Installation Notes

Installation is performed by a machinist or machine operator. Secure the shank fully within the collet or end mill holder and torque the retention mechanism according to the toolholder manufacturer specifications before running the spindle. Inspect the cutting edges for chips or damage before each use. Never exceed the spindle speed and feed rate limits appropriate for the tool diameter, material, and machine being used.
