Value Collection 723-1047 Square End Mill 9/16 in Cobalt

Product Description

The VALUE COLLECTION 723-1047 is a cobalt square end mill designed for material removal in ferrous and high-temperature alloy applications. Built from M42 cobalt high-speed steel, this single-end mill features a 9/16-inch cutting diameter, a 1-1/8-inch length of cut, and a 30-degree helix angle. The bright uncoated finish and right-hand spiral flute geometry make it a reliable choice for machinists running general-purpose milling operations on steel, stainless steel, cast iron, and high-temp alloys. Centercutting capability allows for plunge entry without a pre-drilled pilot hole.

This end mill suits production and job-shop environments where fractional-inch tooling is standard. It is appropriate for knee mills, CNC machining centers, and manual mills running conventional or climb milling passes. The 1/2-inch shank diameter fits standard ER collets and end mill holders common across most vertical milling setups. With a 3-1/8-inch overall length, it offers adequate reach for most standard-depth pockets and slots without excessive deflection risk.

Key Features

• M42 cobalt construction for improved heat and wear resistance over standard HSS tooling
• Centercutting design allows direct plunge milling without pre-drilling
• 30-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Right-hand cut and right-hand flute orientation compatible with standard spindle rotation
• Bright uncoated finish suitable for use with or without coolant on a wide range of ferrous materials
• Regular-length series for stable performance in pocket, slot, and peripheral milling

Compatibility

Rated for primary workpiece materials including steel, stainless steel, cast iron, and high-temperature alloys (material codes P, M, K, S). Fits standard 1/2-inch end mill holders and ER collet chucks.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered off before changing tooling. Secure the shank with adequate clamping length in the holder to minimize runout and prevent tool pull-out during cutting. Verify spindle direction is set to right-hand rotation before engaging the cut.
