Value Collection 723-1137 Square End Mill 1-1/2 in Cobalt

Product Description

The VALUE COLLECTION 723-1137 is a square end mill ground from M42 cobalt high-speed steel, designed for material removal in milling operations on machining centers and manual mills. With a 1.5-inch cutting diameter and a 1.625-inch length of cut, it handles slotting, peripheral milling, and plunge cutting in a single-end configuration. The 30-degree helix angle promotes smooth chip evacuation, and the bright uncoated finish suits shops that prefer to apply their own coatings or run the tool dry. Two flutes provide the chip clearance needed when cutting softer ferrous alloys and some stainless grades. Machinists and CNC operators in job shops and production environments are the primary users.

This end mill is suited for milling steel, stainless steel, cast iron, and high-temperature alloys. Its right-hand cut and right-hand flute geometry is compatible with standard spindle rotation on vertical and horizontal machining centers. The 1-inch straight shank seats in standard ER or side-lock toolholders sized for 1-inch bore. The centercutting geometry allows direct plunge entry into the workpiece without a pre-drilled pilot hole, which simplifies pocketing and slotting setups. Regular-length classification keeps the overhang manageable and supports rigidity at full cutting depth.

Key Features

• M42 cobalt steel construction for elevated heat and wear resistance compared to standard HSS
• Centercutting design permits direct plunge milling without a starter hole
• 30-degree helix angle for smooth chip flow and reduced cutting forces
• Bright uncoated finish compatible with dry cutting or user-applied coatings
• Right-hand cut, right-hand flute — standard orientation for most machine spindles
• Two flutes provide generous chip clearance for ferrous and high-temp alloy work

Compatibility

Designed for milling steel, stainless steel, cast iron, and high-temperature alloys. Seats in any 1-inch bore toolholder on vertical or horizontal machining centers and manual knee mills. ISO material codes P, M, K, and S are the rated workpiece categories per the supplier specification.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked before inserting or removing the tool from the holder. Confirm the shank is fully seated and the set screw or collet nut is torqued according to the toolholder manufacturer specifications. Verify spindle direction is set to right-hand rotation before initiating the cut.
