Value Collection 27714 Square End Mill 5/8 in 4 Flute Cobalt

Product Description

The VALUE COLLECTION 27714 is a double-end, four-flute cobalt square end mill designed for milling operations in ferrous and high-hardness materials. Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention that standard HSS tooling cannot match. The cutter measures 5/8 inches in diameter with a 1-3/8 inches length of cut, a matching 5/8 inches shank diameter, and a 5 inches overall length. A 30-degree right-hand spiral helix promotes efficient chip evacuation and smooth cutting action. The bright, uncoated finish suits general-purpose machining where coatings are not required by the application or coolant system.

This end mill is suited for peripheral milling, slotting, and profiling operations on a manual or CNC milling machine. The double-end configuration provides two usable cutting ends, extending service life between tool changes. Right-hand cutting direction and right-hand flute direction are standard for conventional vertical milling setups. It is not center-cutting, so plunge milling is not a recommended operation for this tool. Typical applications include job shops, maintenance machining, and production runs where cobalt tooling is specified for harder workpiece materials.

Key Features

• M42 cobalt HSS construction for elevated heat and wear resistance
• Double-end design provides two cutting ends per tool
• Four right-hand spiral flutes at 30-degree helix angle for efficient chip flow
• 5/8 inches diameter with matching 5/8 inches shank for direct collet or end mill holder mounting
• Bright/uncoated finish suitable for general-purpose and ferrous milling
• Regular length classification with 1-3/8 inches length of cut

Compatibility

Designed as a general-purpose fractional-inch cobalt square end mill compatible with standard milling machine spindles and toolholders accepting a 5/8 inches straight shank.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power isolated. Secure the shank in a properly sized collet or end mill holder and verify runout before cutting. Do not use this tool for plunge cuts, as it is not center-cutting. Follow applicable machine tool safety practices and consult the machine manufacturer guidelines for speeds and feeds appropriate to the workpiece material.
