Value Collection 724-4191 Roughing Finishing End Mill

Product Description

The VALUE COLLECTION 724-4191 is a roughing finishing end mill designed for aggressive material removal with a refined finish in a single tool. Built from M42 cobalt high-speed steel, it delivers the heat and wear resistance needed for cutting steel, stainless, and other tough alloys. The 3/4 inch diameter, 4-flute geometry with a 30-degree helix angle balances chip evacuation with surface finish quality. At 2.5 inches length of cut and 4.625 inches overall length, this tool suits deep-slot and peripheral milling operations on manual mills and CNC machining centers alike. The Weldon flat shank provides positive drive retention in standard end mill holders.

This end mill is suited for job shops, tool rooms, and production environments handling ferrous metals and high-nickel alloys where standard HSS tooling falls short. The right-hand cut, right-hand flute configuration is the standard orientation for conventional milling setups. Single-end construction makes it a straightforward replacement when one cutting end is worn. The bright uncoated finish means it can be resharpened without stripping a coating layer, keeping regrind costs low.

Key Features

• M42 cobalt material grade for elevated heat resistance versus standard M2 HSS
• 30-degree helix angle balances chip flow and radial cutting forces
• 4-flute square end geometry supports both roughing and finishing passes
• Weldon flat shank ensures positive engagement in end mill holders and reduces pullout risk
• Bright uncoated surface is regrind-friendly without coating removal
• Right-hand cut and right-hand flute direction for standard milling orientation

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 3/4 inch end mill holders and collet chucks used in manual knee mills and CNC vertical machining centers.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the Weldon flat shank fully into the holder and tighten the set screw against the flat to prevent axial pullout. Verify runout with a dial indicator before beginning a cut, particularly for finishing passes where tolerance is critical.
