Helical Solutions 30077 Square End Mill 3/16 in 4 Flute Carbide

Product Description

The HELICAL SOLUTIONS 30077 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 3/16 inch cutting diameter and a 5/16 inch length of cut, this single-end tool is built for profiling, slotting, and contouring in ferrous and non-ferrous materials. The 4-flute helical design with variable index improves chip evacuation and reduces chatter, supporting consistent surface finishes. An APLUS coating enhances wear resistance and extends tool life at elevated cutting speeds. The 3/16 inch straight cylindrical shank fits standard collets and tool holders. Overall length is 2 inches. This tool weighs approximately 0.026 pounds.

This end mill is suited for CNC machining centers and manual mills where tight-tolerance cuts are required. The right-hand cutting and right-hand flute direction make it compatible with standard spindle configurations. It is centercutting, allowing plunge milling in addition to conventional profiling passes. Typical applications include side milling, pocket milling, and finishing passes in steel, stainless, aluminum, and similar materials. Machinists and tool-and-die professionals working in job shop, production, or maintenance machining environments will find this a reliable general-purpose choice for small-diameter work.

Key Features

• 3/16 inch cutting diameter with matching 3/16 inch straight cylindrical shank
• 4-flute helical geometry with variable index to reduce harmonics and improve finish
• Centercutting capability allows direct plunge entry into workpiece
• APLUS coating for improved wear resistance and heat management
• Right-hand cut, right-hand flute direction for standard spindle use
• Solid carbide construction for rigidity and dimensional stability

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill compatible with standard collet systems and tool holders accepting a 3/16 inch straight cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a calibrated collet or tool holder rated for the shank diameter and verify runout before cutting. Consult the machine manufacturer and applicable shop standards for recommended speeds, feeds, and depth-of-cut parameters based on workpiece material.
