YG-1 G8A46932 Ball End Mill 1.50mm 2 Flute Solid Carbide

Product Description

The YG-1 G8A46932 is a single-end ball end mill designed for precision milling in steel and hard materials. Built from nanograin solid carbide with a PVD-applied BLUE coating, it delivers consistent performance across both roughing and finishing passes. The 1.50 mm cutting diameter and 0.75 mm nose radius make it well-suited for fine-detail work and tight-radius contouring. A 30-degree medium helix angle promotes smooth chip evacuation, while the extended-reach design with a 1.45 mm neck diameter and 18.80 mm neck length provides clearance for deep-cavity applications without sacrificing rigidity.

This end mill is intended for use in CNC machining centers and high-speed milling operations where small-diameter tooling is required. Its extended reach geometry makes it particularly useful for mold and die work, aerospace component machining, and precision part production where access to recessed features is required. The straight-cylindrical shank at 4.00 mm diameter provides secure clamping in standard collet or end mill holders. It is suited for professional machinists and tool and die makers working in steel and hard material applications.

Key Features

• Nanograin solid carbide construction for hardness and wear resistance in steel and hard materials
• PVD BLUE coating reduces friction and extends tool life in demanding cuts
• Extended reach with 1.45 mm neck diameter and 20.00 mm reach length for deep-cavity access
• 30-degree medium helix angle supports chip flow on both roughing and finishing passes
• 0.75 mm nose radius enables tight-radius contours and smooth ball-end profiling
• Right-hand cut and right-hand spiral flutes; no chipbreaker for clean finish passes

Compatibility

Designed for use in CNC machining applications targeting steel and hard materials; part of the YG-1 G8A46 Series of extended-reach ball end mills with a straight-cylindrical shank for standard collet and end mill holder fitment.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for small-diameter carbide tooling. Ensure the collet or holder bore is clean and free of debris before seating the 4.00 mm shank. Carbide tooling is brittle - avoid excessive runout or side-loading, which can cause premature chipping. Confirm spindle speed and feed rate parameters are appropriate for the 1.50 mm cutting diameter before engaging the workpiece.
