Sgs 46345 Ball End Mill 0.3937 in 4 Flute Solid Carbide

Product Description

The SGS 46345 is a solid carbide ball end mill designed for finishing operations in demanding machining environments. With a 0.3937-inch (10 mm) cutting diameter and a 0.866-inch length of cut, this 4-flute tool delivers smooth surface finishes in a single-end configuration. The AlTiN coating provides thermal resistance and wear protection at elevated cutting temperatures. Variable helix and variable index geometry reduce chatter and harmonic vibration, improving tool life and cut quality. The micrograin carbide substrate supports sharp edges and consistent performance across a range of workpiece materials.

The SGS 46345 is suited for finishing passes in materials including hardened steels, cast iron, stainless steel, titanium alloys, and other high-temperature alloys, corresponding to workpiece material codes H, K, M, P, and S. The 10 mm shank diameter fits standard ER or shrink-fit toolholders. At 72 mm overall length and a regular length classification, this tool is appropriate for shallow-to-moderate depth finishing in vertical machining centers and CNC milling applications across job shop and production environments.

Key Features

• AlTiN coating for high-temperature wear resistance and extended tool life
• Variable helix and variable index geometry reduce vibration and chatter during finishing cuts
• Micrograin solid carbide substrate for sharp, consistent cutting edges
• 4-flute spiral configuration optimized for finishing material removal
• Right-hand cut and right-hand flute direction for standard spindle compatibility
• Single-end design; no coolant-through, no chipbreaker - streamlined for finishing applications

Compatibility

Compatible with workpiece material codes H (hardened steels), K (cast iron), M (stainless steel), P (steel), and S (high-temperature alloys and titanium). Fits any toolholder accepting a 10 mm shank diameter. Part of the SGS Series Z1MB.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the toolholder is clean and free of debris before seating the shank; verify runout with a dial indicator before cutting. Confirm spindle speed and feed rate are appropriate for the workpiece material and depth of cut before engaging the tool. Follow all machine guarding and PPE requirements per shop safety standards.
