Value Collection 724-4262 Roughing End Mill 1 in Cobalt

Product Description

The VALUE COLLECTION 724-4262 is a single-end, cobalt roughing-finishing end mill designed for aggressive material removal and finishing operations in one tool. Built from M42 cobalt high-speed steel, it handles tough ferrous and non-ferrous materials where standard HSS tooling falls short. The 1-inch diameter cutting face features 3 flutes with a 30-degree right-hand helix, producing efficient chip evacuation and a smooth cutting action. The Weldon flat shank provides a positive mechanical grip in the holder, preventing pullout under high feed loads. At 0.086 pounds, it is a solid, balanced tool suited for manual mills and CNC machining centers alike.

This end mill is appropriate for milling operations in job shops, tool rooms, and production environments. It is used in face milling, slotting, and profiling applications on steel, stainless, cast iron, and similar materials. The square end geometry suits shoulder milling and step cuts. With a 2-inch length of cut and 4.5-inch overall length, it provides sufficient reach for common workholding setups without excessive overhang.

Key Features

• M42 cobalt construction for increased heat and wear resistance over standard M2 HSS
• 3-flute geometry balances chip load and surface finish in roughing-to-finishing transitions
• 30-degree right-hand helix promotes smooth cutting action and upward chip evacuation
• Weldon flat shank provides mechanical pullout resistance in standard end mill holders
• Bright/uncoated finish — suitable for regrinding and re-use cycles
• Non-centercutting square end design for peripheral and slot milling

Compatibility

Designed as a direct-fit replacement for standard 1-inch shank cobalt end mills used in milling machines and machining centers accepting Weldon flat end mill holders.

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 inserting or removing tooling. Seat the Weldon flat shank fully into the holder and tighten set screws to the holder manufacturer's specification. Verify runout with a dial indicator before beginning a cut, and confirm workholding is secure prior to engaging the cutter.
