Helical Solutions 56602 Ball End Mill 5/8 in 4 Flute Carbide

Product Description

The HELICAL SOLUTIONS 56602 is a solid carbide, single-end ball end mill designed for milling steel, stainless steel, and cast iron in both roughing and finishing operations. It features a 5/8 inch (0.6250 inch) mill diameter with a 0.3125 inch nose radius, a 2 inch length of cut, and a 4 inch overall length. The 4-flute, variable-index geometry reduces harmonic vibration during aggressive cuts, and the APLUS PVD coating extends tool life in ferrous workpiece materials. Licensed HVAC and trade machinists running CNC or manual mills specify this tool for demanding ferrous alloy work.

The 56602 is intended for use on steel, stainless steel, and cast iron workpieces, covering ISO material codes P, M, and K. The standard length and straight cylindrical 5/8 inch shank make it compatible with common collet and end mill holder systems used on vertical machining centers and milling machines in job shop and production environments. Material removal classification covers both roughing and finishing passes, making it a practical single-tool choice across multiple operations on ferrous stock.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• Variable-index 4-flute geometry reduces chatter and improves surface finish
• APLUS PVD coating enhances heat resistance and extends tool life on steel and cast iron
• Ball end profile with 0.3125 inch nose radius suited for 3D contour and profiling work
• Right-hand cut and right-hand spiral flute direction for standard CNC mill compatibility
• Single-end design with straight-cylindrical shank fits standard collets and end mill holders

Compatibility

Designed for use on steel, stainless steel, and cast iron workpieces (ISO material codes P, M, K). Fits standard 5/8 inch collets and end mill holders with h6 shank diameter tolerance. Part of the Helical Solutions 4 Flute Ball Variable Pitch (Aplus) End Mills for Steels, Tool Steels, and Cast Iron series.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before loading or removing the tool. Seat the shank fully in the collet or holder and torque the retention system per the toolholder manufacturer specification. Confirm runout does not exceed the 0.0005 inch TIR maximum before beginning a cut.
