Helical Solutions 56167 Ball End Mill 1/4 in 4 Flute Carbide

Product Description

The HELICAL SOLUTIONS 56167 is a 4-flute solid carbide ball end mill designed for milling steel, stainless steel, and cast iron. It features a 0.25-inch mill diameter, a 1-inch length of cut, and a 3-inch overall length. The variable index flute geometry reduces harmonic vibration during aggressive cuts, making it suitable for both roughing and finishing operations. An APLUS PVD coating improves wear resistance and edge retention at elevated cutting temperatures. This end mill is intended for use by machinists and tooling professionals working on CNC machining centers and milling machines.

This end mill is built for ferrous workpiece materials including carbon steels, tool steels, stainless steels, and cast iron. It is a single-end, right-hand cut, right-hand spiral tool with a straight-cylindrical shank. Typical applications include profile milling, contouring, and 3D finishing passes on hardened or abrasion-resistant workpieces. The standard-length configuration fits a wide range of toolholders commonly used in production and job-shop environments.

Key Features

• Variable index flute spacing reduces chatter and improves surface finish on ferrous materials
• APLUS PVD coating provides high wear resistance and heat tolerance for steel and cast iron applications
• 0.125-inch nose radius enables contoured and blended surface milling
• Solid carbide construction delivers rigidity and dimensional stability under high cutting loads
• Single-end, right-hand cut design compatible with standard CNC toolholding systems
• Handles both roughing and finishing material removal in a single tool

Compatibility

Designed for machining steel, stainless steel, tool steels, and cast iron workpieces. Part of the HELICAL SOLUTIONS 4 Flute Ball Variable Pitch APLUS series for ferrous materials. Fits standard 0.25-inch straight-cylindrical bore toolholders with h6 shank diameter tolerance.

Installation Notes

Installation and tool changes should be performed with the machine in a full stop, lockout condition per applicable shop safety procedures. Ensure the toolholder bore and shank are clean and free of chips before seating. Verify runout does not exceed the maximum TIR specification before beginning a cut. Follow the manufacturer's recommended speeds and feeds for the specific workpiece material and coating grade.
