Value Collection 934-000-011 Square End Mill 3/16 in Cobalt

Product Description

The VALUE COLLECTION 934-000-011 is a cobalt square end mill designed for milling, slotting, and profiling operations on ferrous and non-ferrous materials. Built from M42 cobalt high-speed steel, it offers improved heat and wear resistance compared to standard HSS tooling. The double-end configuration provides two usable cutting ends, extending tool life between replacements. With a 3/16 inch diameter, a 1/2 inch length of cut, and a 40-degree helix angle, this end mill suits detail work and light-to-moderate material removal in manual mills and CNC machining centers. Machinists and tool-and-die technicians are the primary users of this tool.

This end mill fits applications requiring a small-diameter cutting tool in ferrous steels, stainless steel, cast iron, and similar materials where cobalt tooling is preferred over carbide due to its toughness and resistance to chipping under interrupted cuts. The straight shank and standard regular-length geometry make it compatible with common collet chucks and end mill holders. It is well-suited for job shops, maintenance machining, and production environments where a reliable, uncoated cobalt option is needed for precision work in confined areas or on small-featured parts.

Key Features

• M42 cobalt construction provides superior heat resistance and longer tool life versus standard HSS
• Double-end design yields two cutting ends per tool, reducing per-edge tooling cost
• 40-degree right-hand spiral helix promotes efficient chip evacuation and smooth cutting action
• Center-cutting geometry allows plunge cutting as well as peripheral and slot milling
• Bright/uncoated finish maintains sharp edge geometry and works without additional coating friction on softer alloys
• Straight shank fits standard collet chucks and end mill holders without special adapters

Compatibility

Designed as an OEM-style replacement or standard tooling option for use in any milling machine or machining center accepting a 3/16 inch straight-shank end mill with a standard collet or end mill holder.

Installation Notes

Installation is performed by a machinist or tooling technician. Always ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth and tighten to the tool holder manufacturer's specification. Inspect the cutting edges for chips or damage before each use, and discard or re-grind worn ends rather than running a compromised edge.
