The SGS 30189 is a 6-piece solid carbide square end mill set designed for precision milling operations across a range of common cutter diameters. Each mill in the set features a 4-flute, single-end, center-cutting geometry ground from micrograin solid carbide, providing the rigidity and edge retention needed for ferrous and non-ferrous metal cutting. The uncoated finish suits applications where coating buildup or heat sensitivity is a concern. This set covers six standard mill diameters, making it a practical bench stock solution for machine shops, tool rooms, and maintenance facilities running manual or CNC milling equipment.
This set is suited for general-purpose milling tasks including slotting, profiling, and peripheral cutting in metals, plastics, and composites. The six included cutters span diameters of 1/8 inch, 3/16 inch, 1/4 inch, 5/16 inch, 3/8 inch, and 1/2 inch, covering the most commonly called-upon sizes in jobbing and production environments. Shank diameters correspond to standard collet sizes of 1/8 inch, 1/4 inch, 3/8 inch, and 1/2 inch depending on cutter size. The regular length configuration fits standard milling setups without requiring extended-reach toolholding.
Designed for use in standard milling machines and CNC machining centers equipped with collets or end mill holders sized to match the included shank diameters. Series 1 regular-length geometry fits conventional toolholding without modification.
End mills should be installed by a qualified machinist or toolroom technician using a properly sized collet or end mill holder torqued to the machine manufacturer's specification. Ensure the spindle is fully powered down and locked out before changing tooling. Inspect each cutter for chipping or runout before use, and confirm holder cleanliness to prevent premature tool wear or deflection.
