Sgs 34918 Ball End Mill 0.25 in 3 Flute Solid Carbide

Product Description

The SGS 34918 is a solid carbide ball end mill designed for precision milling of non-ferrous metals and similar materials. With a 0.25 inch mill diameter, a 1 inch length of cut, and a 3-flute spiral geometry, this tool delivers efficient chip evacuation and smooth surface finishes in finishing and semi-finishing operations. The 38-degree helix angle promotes aggressive chip flow while maintaining cutting stability. Micrograin carbide construction provides the hardness and edge retention needed for tight-tolerance work in production and job-shop environments. This is a single-end, right-hand cut tool in the SGS Series 43 lineup.

This end mill is suited for milling non-ferrous metals including aluminum, brass, copper, and similar materials. It fits standard CNC machining centers and manual mills equipped with an ER or collet-style toolholder accepting a 0.25 inch shank. The regular-length body and 3 inch overall length make it appropriate for general-purpose profiling, contouring, and slot milling where extended reach is not required. Machinists and toolroom operators working in precision machining environments are the primary users of this tool.

Key Features

• 0.25 inch mill diameter with mill diameter tolerance of +0.0000 to 0.00035 inches for precise fitment
• 3-flute spiral geometry supports efficient chip evacuation in non-ferrous applications
• 38-degree helix angle balances cutting aggressiveness with tool stability
• Micrograin solid carbide construction for enhanced hardness and edge retention
• Uncoated finish - suitable for applications where coating is not required or where re-sharpening is anticipated
• Single-end, right-hand cut with h6 shank diameter tolerance for consistent toolholder fit

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide ball end mill for CNC machining centers and manual mills accepting a 0.25 inch straight shank with h6 tolerance. Primary workpiece material code N indicates non-ferrous metal applications.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and powered down before changing tooling. Seat the shank fully into the collet or toolholder and torque the retention nut to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning the cut, as excessive runout will accelerate edge wear on carbide tooling.
