Sgs 30178 Ball End Mill 0.125 in 4 Flute Solid Carbide

Product Description

The SGS 30178 is a solid carbide ball end mill designed for precision milling operations across a range of metalworking and machining applications. With a 0.125 inch cutting diameter and a 0.375 inch length of cut, this four-flute tool delivers smooth, consistent material removal in contoured and profiled surfaces. The micrograin carbide construction provides the hardness and edge retention needed for demanding cutting conditions. The 30-degree helix angle promotes efficient chip evacuation, while the variable index flute spacing reduces chatter and vibration during the cut. This end mill is suited for use in CNC machining centers and manual mills operated by skilled machinists and tooling professionals.

The SGS 30178 is intended for use in profiling, slotting, and contouring operations on a broad range of workpiece materials. Its primary material compatibility codes cover cast iron, non-ferrous metals, stainless steel, aluminum, steel alloys, and heat-resistant superalloys. With a 0.125 inch shank diameter and 1.5 inch overall length, this regular-length single-end tool fits standard collet systems and is well-suited to tight-tolerance finish milling and die work in both production and job-shop environments.

Key Features

• Solid micrograin carbide construction for superior hardness and wear resistance
• Four-flute, variable index design reduces harmonic chatter during cutting
• 30-degree right-hand spiral helix promotes efficient chip evacuation
• Ball end profile enables profiling, contouring, and 3D surface milling
• Uncoated finish suitable for use across multiple workpiece material categories
• Single-end design with right-hand cutting direction for standard spindle rotation

Compatibility

Designed for use with standard 1/8 inch collet systems on CNC machining centers and manual milling machines. Compatible workpiece material categories include cast iron, non-ferrous metals, stainless steel, aluminum alloys, steel, and heat-resistant superalloys as indicated by primary material codes H, K, M, N, P, and S.

Installation Notes

This end mill is installed and changed by qualified machinists following standard toolroom procedures. Secure the shank fully within the collet to the recommended engagement depth and verify runout before cutting. Power down and lock out the spindle before any tool change. Cutting parameters including speed, feed, and depth of cut should be selected based on workpiece material, machine rigidity, and toolholder condition — do not exceed the tool geometry limits for radial or axial engagement.
