Value Collection 724-4026 End Mill 1/4 in 4 Flute Cobalt

Product Description

The VALUE COLLECTION 724-4026 is a single-end roughing finishing end mill designed for metal removal and surface finishing in one tool. Built from M42 cobalt high-speed steel, it handles tough ferrous and non-ferrous materials with a 30-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The 4-flute, right-hand cutting geometry delivers a balance between stock removal rates and surface finish quality. At 0.25 inches in diameter with a 0.875-inch length of cut and 2.6875-inch overall length, this end mill is sized for light-duty slotting, profiling, and finishing passes on milling machines and machining centers.

This end mill is suited for general-purpose milling operations in job shops, maintenance machining, and production environments. The square end geometry makes it appropriate for shoulder milling, pocketing, and contour work. The Weldon flat shank at 0.375 inches accommodates side-lock tool holders, providing positive grip and reduced pullout risk during aggressive cuts. The bright uncoated finish keeps the tool cost-effective for applications where a specialized coating is not required.

Key Features

• M42 cobalt construction for improved heat and wear resistance over standard HSS
• 4-flute right-hand configuration balances cutting speed and finish quality
• 30-degree helix angle promotes efficient chip flow and reduced cutting forces
• Weldon flat shank prevents tool pullout in side-lock holders
• Square end geometry supports shouldering, slotting, and profiling operations
• Single-end design, bright uncoated finish

Compatibility

Designed for use in standard milling machines and machining centers with side-lock or set-screw tool holders accepting a 0.375-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and locked out before inserting or removing the end mill from the tool holder. Seat the Weldon flat against the set screw contact point and torque the holder fastener per the tool holder manufacturer specification. Verify runout with a dial indicator before cutting to avoid premature tool wear or breakage.
