Seco 17014211 Roughing End Mill 3/4 in 4 Flute Cobalt

Product Description

The SECO 17014211 is a single-end cobalt roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, it delivers heat and wear resistance needed for tougher workpiece materials. The 3/4 inch cutting diameter is matched by a 3/4 inch length of cut and a 3/4 inch shank diameter. A 30-degree maximum helix angle combined with right-hand cutting and right-hand spiral fluting promotes efficient chip evacuation. Four flutes provide a strong cutting edge geometry suited for roughing passes. Machinists and tool-and-die professionals use this end mill in CNC and manual milling machines for stock removal prior to finishing operations.

This end mill is suited for shop environments requiring reliable roughing performance in a standard regular-length format. The bright, uncoated finish makes it straightforward to inspect for wear. No coolant-through capability means it is best paired with flood or mist cooling at the machine. At 3 inches overall length, it fits standard R8, CAT, BT, and similar toolholders accepting a 3/4 inch shank. It is part of the SECO REM710 series and is intended for professional machining environments.

Key Features

• M42 cobalt construction for elevated heat and wear resistance during heavy roughing cuts
• 4 right-hand spiral flutes with right-hand cutting direction for efficient chip flow
• 3/4 inch cutting diameter with 3/4 inch length of cut and 3 inch overall length
• 30-degree maximum helix angle for balanced cutting forces in roughing applications
• Bright, uncoated finish allows easy visual wear inspection
• Single-end design; part of the SECO REM710 series

Compatibility

Designed as a standard-shank roughing end mill compatible with milling machine toolholders accepting a 3/4 inch shank diameter in CNC and manual machining applications.

Installation Notes

Installation is performed by a qualified machinist. Ensure the milling machine spindle is fully stopped and de-energized before loading or changing tooling. Seat the shank fully into the toolholder and secure to the manufacturer torque specification for that holder type. Confirm runout with a dial indicator before beginning the cut, as excessive runout accelerates flute wear on cobalt tooling.
