Value Collection 723-1125 Square End Mill 1-1/4 in 2 Flute Cobalt

Product Description

The VALUE COLLECTION 723-1125 is a cobalt square end mill designed for material removal in milling operations on steel, stainless steel, cast iron, and high-temperature alloys. Machined from M42 cobalt high-speed steel, it delivers greater heat and wear resistance than standard HSS tooling. The cutter runs a 1.25-inch diameter with a 1.625-inch length of cut, making it well suited to slotting, profiling, and peripheral milling at moderate depths. The bright uncoated finish maintains close dimensional tolerances and works with a wide range of cutting fluids. Licensed machinists and toolroom operators are the primary users of this end mill in production and job-shop environments.

This end mill is intended for use in vertical and horizontal milling machines, CNC machining centers, and manual knee mills where a 1.25-inch shank can be held in a collet chuck, end mill holder, or Weldon-style holder. It is a single-end tool with a right-hand cut and right-hand spiral flute at a 30-degree helix angle. The centercutting geometry allows plunge entry directly into the workpiece. Primary workpiece materials include steel, stainless steel, cast iron, and high-temperature alloys, consistent with ISO material codes P, M, K, and S.

Key Features

• M42 cobalt HSS construction for improved heat resistance over standard M2 tooling
• Centercutting geometry enables direct plunge cutting without a pilot hole
• 30-degree helix angle promotes efficient chip evacuation in ferrous materials
• Bright uncoated finish compatible with oil-based and water-soluble coolants
• Right-hand cut and right-hand flute direction for standard spindle rotation
• Single-end design with a regular-length body for rigidity in conventional setups

Compatibility

Designed for use on steel, stainless steel, cast iron, and high-temperature alloy workpieces. Fits any spindle or toolholder accepting a 1.25-inch straight shank end mill.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the shank fully in a properly sized end mill holder or collet and torque the retention hardware to the machine manufacturer's specification before running. Power down and lock out the spindle drive before changing tooling. Do not exceed the depth-of-cut or feed-rate limits established by the machine tool builder and cutting tool guidelines for the workpiece material being machined.
