Helical Solutions 48395 Square End Mill 0.5in 3 Flute Carbide

Product Description

The HELICAL SOLUTIONS 48395 is a 3-flute square end mill designed specifically for aluminum milling applications. Constructed from solid carbide, it features a 40-degree helix angle and a variable index geometry that reduces harmonic vibration and chatter during high-speed cuts. The bright, uncoated finish is well-suited for non-ferrous materials where coating adhesion or built-up edge can be a concern. With a 0.5-inch cutting diameter and 1.25-inch length of cut, this tool handles slotting, profiling, and peripheral milling operations in aluminum alloys. Licensed machinists and CNC operators are the primary users of this end mill in production and job-shop environments.

This end mill is built for aluminum and other non-ferrous materials where chip evacuation and surface finish are critical. The 3-flute configuration balances chip load capacity with flute volume, allowing higher feed rates without packing. The variable index spacing between flutes disrupts resonance frequencies, making it effective in both rigid machining centers and less-rigid setups. It is sold as a single unit and is appropriate for both production runs and one-off prototype work where a dedicated aluminum end mill is needed.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous machining
• 40-degree helix angle optimized for aluminum chip evacuation
• Variable index flute spacing reduces chatter and harmonic vibration
• Center-cutting capable, allowing direct plunge entry
• Bright, uncoated finish prevents built-up edge on aluminum
• Straight-cylindrical shank for standard ER collet or end mill holder compatibility

Compatibility

Designed as an OEM-specification solid carbide square end mill for aluminum milling applications, compatible with standard 0.5-inch bore ER collets, shrink-fit holders, and end mill holders used in CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and locked out before loading or removing the tool from its holder. Seat the shank fully in the collet or holder to the recommended engagement depth before torquing the retention nut. Verify runout with a dial indicator after tool change to confirm proper seating and avoid premature tool wear or part damage.
