Seco 17010417 Roughing End Mill 1-1/4 in 6 Flute Cobalt

Product Description

The SECO 17010417 is a single-end cobalt roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a bright/uncoated finish, it delivers the hardness and heat resistance required for cutting ferrous and non-ferrous metals under demanding conditions. The tool features a 1.25-inch mill diameter, six flutes, and a 4-inch length of cut, making it well suited for full-depth slotting and profiling passes where maximizing chip clearance and tool life is the priority. Licensed machinists and toolroom professionals specify this series for production and maintenance machining applications.

This roughing end mill fits conventional vertical and horizontal milling machines as well as CNC machining centers where a 1-1/4-inch straight shank is required. The REM445 series is engineered for regular-length applications involving roughing passes in steel, alloy steel, stainless steel, and similar workpiece materials. The non-center-cutting geometry means it is intended for side milling, slotting from a pre-drilled entry, or plunge operations where axial entry is not required. Right-hand cutting and right-hand flute direction are standard for this configuration.

Key Features

• M42 cobalt material grade for elevated hardness and heat resistance compared to standard HSS
• Six flutes for improved chip load distribution and surface finish during roughing passes
• 4-inch length of cut accommodates deep-pocket and thick-workpiece applications
• Bright/uncoated finish — no coating compatibility concerns with cutting fluids or regrinding
• Right-hand cut and right-hand helix for use with conventional milling spindle rotation
• Non-center-cutting design suited for side milling and pre-drilled plunge entry

Compatibility

Designed as an OEM-style roughing end mill for use in milling machines and machining centers accepting a 1-1/4-inch straight shank tool holder.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and locked out per applicable machine guarding and OSHA lockout/tagout requirements. Seat the shank fully and evenly in the tool holder collet or end mill adapter and torque the retention hardware to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning the cut. Inspect the cutting edges for chipping or wear before each use and replace the tool if edge integrity is compromised.
