Sgs 30144 Ball End Mill 0.3438 in 4 Flute Solid Carbide

Product Description

The SGS 30144 is a solid carbide ball end mill designed for precision milling operations across a wide range of materials. With a 0.3438-inch (11/32-inch) cutting diameter and a 4-flute configuration, it delivers smooth surface finishes and efficient material removal in a single-end cutting geometry. The 30-degree helix angle promotes clean chip evacuation, and the micrograin carbide construction provides the hardness and wear resistance needed for demanding cuts. It is installed by machinists and toolroom operators working on CNC machining centers and manual milling equipment.

This end mill is suited for profiling, contouring, and slotting operations in both production and job-shop environments. The Series 1B regular-length geometry fits standard tool holders accepting a 3/8-inch shank. Primary workpiece material codes cover a broad spectrum including ferrous and non-ferrous metals, high-temperature alloys, and cast materials. The uncoated finish makes it a straightforward choice when coating compatibility with specific cutting fluids or materials is a concern.

Key Features

• Solid micrograin carbide construction for high hardness and extended tool life
• 4-flute spiral design improves surface finish and chip flow
• 30-degree helix angle supports efficient chip evacuation
• Variable index geometry reduces chatter and vibration during cuts
• Single-end configuration with right-hand cut and right-hand flute direction
• Uncoated finish compatible with a wide range of cutting fluid applications

Compatibility

Designed for use in standard tool holders and collet chucks accepting a 3/8-inch shank diameter. Suitable for machining workpiece materials coded H, K, M, N, P, and S per the supplier material classification system.

Installation Notes

Installation should be performed by a qualified machinist following safe tooling practices. Ensure the spindle is fully stopped and locked out before inserting or removing the end mill from the tool holder. Verify shank runout and holder cleanliness before securing to maintain diameter tolerance integrity. Follow machine manufacturer guidelines for speeds and feeds based on workpiece material and depth of cut.
