Value Collection 33032 Roughing Finishing End Mill 1 in Cobalt

Product Description

The VALUE COLLECTION 33032 is a single-end, square-end roughing finishing end mill designed for aggressive material removal combined with a refined finish in a single tool pass. Built from M42 cobalt high-speed steel, it handles the heat and wear demands of ferrous metals, stainless steel, and other hard-to-machine alloys. The 1 inch cutting diameter pairs with a 45-degree helix angle and 3 flutes to deliver strong chip evacuation and reduced vibration during heavy milling operations. This tool is centercutting, allowing plunge cuts as well as conventional side milling. It is sold individually and suits machinists, tool-and-die shops, and maintenance shops running manual mills or CNC equipment.

This end mill is suited for roughing and finishing passes on ferrous and non-ferrous workpieces where a separate roughing tool and finish tool would otherwise be required. The bright, uncoated finish makes it a straightforward choice for general-purpose milling without the added cost of a specialty coating. It is appropriate for use in both job shops and production environments where cobalt tooling is preferred over carbide for its toughness and regrindability. Right-hand cut and right-hand flute direction are standard for conventional vertical mill and CNC machining center setups.

Key Features

• M42 cobalt construction for improved heat resistance and tool life over standard M2 high-speed steel
• 45-degree helix angle promotes smooth cutting action and efficient chip removal
• 3 flutes provide a balance between chip clearance and cutting edge strength
• Centercutting geometry allows direct plunge entry into the workpiece
• Straight shank with 3/4 inch diameter fits standard ER and side-lock collet systems
• Bright uncoated finish allows easy visual inspection for wear and supports regrinding

Compatibility

Designed as a general-purpose replacement or stock end mill for manual vertical mills and CNC machining centers accepting a 3/4 inch straight shank. Verify spindle collet or chuck capacity before installation.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the minimum recommended engagement depth in the collet or chuck — insufficient engagement increases deflection and breakage risk. Verify runout with a dial indicator before beginning the cut, particularly on finishing operations where dimensional accuracy is critical.
