Helical Solutions 24167 Square End Mill 3/8in 7 Flute Carbide

Product Description

The HELICAL SOLUTIONS 24167 is a solid carbide square end mill designed for finish milling operations in steel and ferrous alloys. With a 3/8 inch cutting diameter, seven helical flutes, and an APLUS coating, this tool is built for high-feed finishing passes where surface finish and edge life are the priority. The seven-flute geometry increases the number of cutting edges in contact with the workpiece, reducing chip load per flute and enabling faster feed rates without sacrificing finish quality. Machinists and CNC operators running steel components in production or job-shop environments will find this end mill well-suited to their finishing stages.

This end mill fits standard 3/8 inch collets or end mill holders and is part of HELICAL SOLUTIONS' End Mills for Steels series, specifically the 7 Flute Square Finisher line. It is intended for finishing operations in steels, including low-carbon, alloy, and tool steels, where controlled material removal and tight surface finish tolerances are required. The straight-cylindrical shank seats securely in precision tool holders, making it appropriate for both vertical and horizontal CNC machining centers.

Key Features

• Seven helical flutes for high feed-rate finishing with reduced chip load per flute
• APLUS coating for improved wear resistance and heat management in steel cutting
• Solid carbide construction provides rigidity and edge retention at elevated cutting speeds
• Right-hand cut and right-hand flute direction for standard CNC and manual milling setups
• Center-cutting capable, allowing plunge entry where required
• Straight-cylindrical shank for compatibility with standard collets and end mill holders

Compatibility

Designed as an OEM-style replacement and direct-fit cutting tool for CNC machining centers and manual mills using 3/8 inch tool holders or collets. Part of the HELICAL SOLUTIONS End Mills for Steels - 7 Flute - Square - Finisher series.

Installation Notes

Installation and tool changes should be performed with the machine in a full stop and lockout state per standard shop safety practice. Seat the straight-cylindrical shank fully into a properly sized collet or end mill holder and torque the retention mechanism to the tool holder manufacturer's specification. Inspect the cutting edges for chips or coating damage before mounting. Confirm runout with a dial indicator when tight tolerances or fine surface finishes are critical.
