Seco 03116011 Corner Radius End Mill 1 in 9 Flute Altin Carbide

Product Description

The SECO 03116011 is a 1-inch diameter, 9-flute solid carbide corner radius end mill designed for high-efficiency roughing operations in demanding metalworking applications. Built on the SCS938R series platform, it features a 0.0300-inch corner radius, a 3.25-inch length of cut, and a 6-inch overall length with a 1-inch straight-cylindrical shank. The micrograin carbide substrate and AlTiN PVD coating deliver the hardness and thermal resistance required when cutting steel, stainless steel, cast iron, and superalloys including titanium. This is a single-end, right-hand cutting, right-hand flute tool with a super-close pitch layout and medium helix geometry.

This end mill is suited for roughing passes in CNC machining centers across job shop and production environments. The super-close pitch and 9-flute configuration support high chip loads and aggressive material removal rates in steel and stainless steel workpieces. The chipbreaker geometry reduces cutting forces during extended-reach roughing passes, making it a practical choice for pocketing, slotting, and peripheral milling where tool stability and chip evacuation are critical. It is intended for use with compatible toolholders and is not designed for centercutting operations.

Key Features

• 9-flute super-close pitch design supports aggressive roughing in ferrous and exotic alloys
• AlTiN PVD coating provides elevated heat resistance for dry or minimal-coolant machining
• 0.0300-inch corner radius with tolerance of plus 0.00100 to minus 0.00100 inches reduces stress concentration at workpiece edges
• Micrograin solid carbide substrate for rigidity and wear resistance
• Chipbreaker geometry reduces cutting forces during long-engagement roughing cuts
• Right-hand cut and right-hand spiral flute; no coolant-through; no centercutting capability

Compatibility

Designed for use with standard toolholders accepting a 1-inch straight-cylindrical shank. Rated for primary workpiece materials including steel (P), stainless steel (M), cast iron (K), and superalloys and titanium (S) per ISO material classification. Part of the SECO SCS938R series.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Secure the shank in an appropriate toolholder to the full recommended engagement depth before running. Confirm runout does not exceed the maximum TIR of 0.0005 inches before starting the cut. This tool is not centercutting and should not be plunged axially into solid material.
