Helical Solutions 30017 Square End Mill 1/8 in 4 Flute Carbide

Product Description

The HELICAL SOLUTIONS 30017 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 1/8 inch (0.125 inch) cutting diameter, a 1/4 inch length of cut, and four helical flutes with a variable index geometry for reduced chatter and improved surface finish. The APLUS coating enhances wear resistance and extends tool life in demanding machining environments. At 1-1/2 inches overall length with a straight cylindrical 1/8 inch shank, this end mill is suited for use in CNC machining centers and manual mills requiring small-diameter tooling.

This end mill is intended for use in machine shops, tool rooms, and production environments where tight tolerances and fine finishes are required. Its centercutting capability allows it to plunge directly into material, making it versatile for slotting, profiling, and pocketing operations. The right-hand cutting and right-hand flute direction are standard configurations compatible with conventional CNC spindle setups. Licensed machinists and CNC operators working in aerospace, mold and die, and general precision machining applications will find this tool well-suited to fine-detail work.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-speed applications
• APLUS coating for extended tool life and improved performance on ferrous materials
• Variable index flute spacing reduces harmonic vibration and chatter
• Centercutting design enables direct plunge entry without pre-drilling
• Right-hand cut and right-hand helix for standard CNC spindle compatibility
• Straight cylindrical shank fits standard collets and end mill holders

Compatibility

Designed as a small-diameter solid carbide square end mill for use in standard 1/8 inch collets and end mill holders on CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for toolholder torque and runout specifications. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Verify collet size and holder condition before seating the shank to prevent runout that can cause premature tool failure or dimensional inaccuracy. Do not exceed the recommended depth of cut or feed rates for the material and coating combination in use.
