Seco 17014168 Roughing End Mill 1-1/4 in 6 Flute Cobalt

Product Description

The SECO 17014168 is a single-end cobalt roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel, it delivers heat and wear resistance needed for cutting harder ferrous and non-ferrous materials. The tool carries a 1.25-inch mill diameter, six flutes, and a 2-inch length of cut, making it well-suited for hogging operations where chip load and tool life are primary concerns. The bright, uncoated finish keeps surface treatment simple and reduces cost where coatings are not required. This is a right-hand cut, right-hand spiral tool with a 30-degree maximum helix angle and a regular-length profile.

This roughing end mill is used in job shop and production machining environments on manual mills, CNC machining centers, and knee mills. It is appropriate for slotting, side milling, and roughing passes where high material removal rate is prioritized over fine surface finish. The 1.25-inch shank diameter matches the mill diameter, allowing direct collet or end mill holder mounting without a reducing adapter. It is commonly employed by machinists working in aerospace, tooling, and general metalworking applications.

Key Features

• M42 cobalt construction for improved heat resistance over standard M2 HSS
• Six-flute geometry increases feed rate potential and improves chip evacuation in roughing cuts
• 30-degree maximum helix angle balances cutting forces and chip flow
• Bright, uncoated finish suits general-purpose roughing without coating cost
• Right-hand cut and right-hand spiral for standard spindle rotation
• Regular length profile fits standard end mill holders without extended-reach tooling

Compatibility

Designed as a direct-mount roughing end mill for 1.25-inch end mill holders, collet chucks, and ER-style collets sized for 1.25-inch shank diameters on manual and CNC milling machines.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom practices. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the holder to the recommended engagement depth and torque set screws per the holder manufacturer specifications. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates flute wear and can cause chatter.
