Value Collection 33027 Roughing Finishing End Mill 1 in Cobalt

Product Description

The VALUE COLLECTION 33027 is a single-end cobalt roughing finishing end mill designed for aggressive material removal followed by a quality surface finish in a single tool. Built from M42 cobalt high-speed steel, it delivers the heat resistance and toughness needed for harder ferrous metals and stainless steels. The 45-degree helix angle promotes efficient chip evacuation and reduces chatter during cuts. With a 1-inch cutting diameter and 3-flute geometry, this end mill balances chip clearance with surface finish capability. It is center-cutting, allowing direct plunge entry without a pre-drilled pilot hole.

This end mill is suited for milling operations in job shops, tool rooms, and production environments where a single tool must handle both roughing and light finishing passes. The straight shank and 1-inch shank diameter make it compatible with standard ER and end mill holders found on vertical machining centers, knee mills, and CNC milling machines. The bright uncoated finish is appropriate for use with cutting fluids on a wide range of metals.

Key Features

• M42 cobalt construction for heat resistance in harder ferrous and stainless materials
• 45-degree helix angle for efficient chip evacuation and reduced chatter
• 3-flute geometry balances chip clearance with improved surface finish
• Center-cutting design allows direct plunge milling without a pilot hole
• Right-hand cut and right-hand flute direction for standard spindle compatibility
• Bright uncoated finish suitable for use with cutting fluids

Compatibility

Designed as an OEM-style replacement or direct-use end mill for standard straight-shank end mill holders and collet chucks accepting a 1-inch shank diameter on vertical and CNC milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before securing or removing the tool from the holder. Ensure the shank is fully seated and the set screw or collet is torqued to the toolholder manufacturer's specification. Inspect the cutting edges for chips or damage before each use.
