Value Collection 723-1219 Square End Mill 3/8 in 2 Flute Cobalt

Product Description

The VALUE COLLECTION 723-1219 is a cobalt steel square end mill designed for material removal in milling operations on ferrous and high-temperature alloy workpieces. Machined from M42 cobalt high-speed steel, it delivers hardness and heat resistance needed when cutting steel, stainless steel, cast iron, and high-temp alloys. The two-flute, spiral configuration with a 30-degree helix angle promotes chip evacuation and reduces cutting forces. At 3/8 inch in diameter with a 1-1/2 inch length of cut, this single-end mill suits slotting, profiling, and peripheral milling in standard CNC and manual milling setups.

This end mill is suited for job shops, toolrooms, and production environments where a reliable general-purpose cobalt cutter is needed. The 3/8 inch shank fits standard ER collet chucks and end mill holders common to knee mills, vertical machining centers, and similar equipment. The bright uncoated finish makes it a straightforward choice for applications where coating compatibility with cutting fluids or workpiece materials is a consideration. Typical users include machinists and CNC operators working with steel and stainless steel components in both prototype and short-run production settings.

Key Features

• M42 cobalt HSS construction for improved heat and wear resistance over standard HSS
• 2-flute design promotes chip clearance in slotting and plunge cuts
• Center-cutting capability allows direct plunge entry into workpiece material
• 30-degree helix angle reduces cutting forces and improves surface finish
• Right-hand cut, right-hand flute geometry for conventional milling setups
• Bright uncoated finish compatible with a wide range of cutting fluids

Compatibility

Designed for milling steel, stainless steel, cast iron, and high-temperature alloys. Compatible with standard 3/8 inch end mill holders and ER collet systems. Rated for workpiece material codes P, M, K, and S per ISO classification.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention hardware to the tool holder specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear on cobalt tooling.
