Value Collection 723-5708 Roughing End Mill 1/4 in Cobalt

Product Description

The VALUE COLLECTION 723-5708 is a single-end cobalt roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, it delivers heat and wear resistance suited to ferrous metals and harder workpiece materials. The 1/4 inch cutting diameter and 3-flute geometry produce a coarser chip load per tooth, reducing chatter and cutting forces during heavy roughing passes. The bright, uncoated finish keeps the tool cost-effective for general-purpose shop use. Machinists and tool-and-die professionals use this style of end mill when removing stock quickly before a finishing pass.

This roughing end mill is suited for use in vertical machining centers, knee mills, and manual bridgeport-style machines running ferrous and non-ferrous workpieces. The 3/8 inch shank seats in standard ER collet chucks, side-lock holders, or Weldon-style tool holders common in production and maintenance machine shops. The right-hand cut and right-hand flute direction are standard for conventional and climb milling on most CNC and manual setups. With a 5/8 inch length of cut and 2-7/16 inch overall length, it fits compact workholding setups without excessive overhang.

Key Features

• M42 cobalt steel construction for improved heat resistance over standard HSS
• 3-flute roughing geometry reduces cutting forces and minimizes chatter on heavy passes
• 1/4 inch cutting diameter with 5/8 inch length of cut for controlled stock removal
• 3/8 inch shank diameter fits standard collet and Weldon-style tool holders
• Bright, uncoated finish — no additional coating cost for general roughing applications
• Right-hand cut, right-hand flute direction for conventional CNC and manual mill setups

Compatibility

Designed as a standard single-end roughing end mill compatible with any machine tool spindle accepting a 3/8 inch shank via ER collet, side-lock, or Weldon-style toolholder.

Installation Notes

Installation should be performed by a qualified machinist following standard tool-holding procedures. Ensure the machine spindle is fully stopped and the machine is powered down or in an e-stop state before changing tooling. Seat the shank to the full recommended engagement depth in the toolholder and torque the retention mechanism per the toolholder manufacturer specification. Inspect the cutting edges before use — cobalt end mills can chip if dropped or improperly stored.
