Seco 17002319 Corner Radius End Mill 1/4 in 7 Flute

Product Description

The SECO 17002319 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining environments. With a 1/4 inch diameter, 1-1/4 inch length of cut, and a 0.0150 inch corner radius, this single-end tool handles both roughing and finishing passes in a single setup. The 7-flute, close-pitch geometry combined with a 38-degree medium helix and AlTiN PVD coating provides thermal resistance and edge stability during aggressive cuts in ferrous and exotic materials. Micrograin carbide construction supports consistent performance at high feed rates and spindle speeds.

This end mill is suited for CNC machining centers working with steel, stainless steel, cast iron, superalloys, and titanium. The extra-long 3 inch overall length and straight cylindrical shank allow reach into deeper pockets and cavities where standard-length tools cannot access. It is intended for use in precision toolholders and is commonly deployed in die and mold work, aerospace component machining, and general metalworking where corner radius geometry helps reduce stress concentration at pocket floors and walls.

Key Features

• 7-flute close-pitch design supports both roughing and finishing in a single tool
• AlTiN PVD coating provides oxidation resistance and extended tool life in high-heat cuts
• 0.0150 inch corner radius reduces stress concentration and improves surface finish at part corners
• Micrograin solid carbide substrate maintains edge integrity in hard and abrasive workpiece materials
• 38-degree medium helix angle balances chip evacuation and cutting stability
• Extra-long 3 inch OAL with 1-1/4 inch LOC enables deep-pocket reach
• Right-hand flute direction and right-hand cutting for standard CNC spindle operation

Compatibility

Designed for use with precision toolholders on CNC machining centers. Rated for primary workpiece materials including steel, stainless steel, cast iron, superalloys, and titanium. Part of the SECO S738R series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the toolholder bore and retention system meet the shank diameter tolerance requirements before mounting. Verify spindle runout does not exceed the maximum TIR specification of 0.0005 inches to protect edge life. Coolant-through is not supported on this tool; external coolant or mist lubrication should be directed at the cutting zone when applicable.
