Helical Solutions 19135 Square End Mill 1/4 in 3 Flute Carbide

Product Description

The HELICAL SOLUTIONS 19135 is a 3-flute solid carbide square end mill engineered for aluminum machining. With a 1/4-inch cutting diameter, a 3/8-inch length of cut, and a 45-degree helix angle, this tool is built to evacuate chips efficiently and reduce built-up edge when cutting non-ferrous materials. The reduced neck design provides extended reach of 2.125 inches, allowing access to deeper pockets and features without sacrificing rigidity. It is single-end, right-hand cutting, and arrives with a bright uncoated finish ready for immediate use. Machinists and CNC operators in production and job-shop environments are the primary users of this tool.

This end mill is designed for cutting aluminum and other non-ferrous materials where high helix angles improve chip flow and surface finish. The reduced neck geometry makes it suitable for deep-pocket milling, profiling, and slotting operations where clearance is limited. The straight cylindrical shank fits standard ER collets and end mill holders commonly found on vertical machining centers and CNC routers. It is sold as a single unit and is appropriate for both prototype work and production runs.

Key Features

• 1/4-inch cutting diameter with 3/8-inch length of cut for precise, controlled engagement
• 45-degree helix angle promotes efficient chip evacuation in aluminum and non-ferrous materials
• Reduced neck design provides 2.125-inch reach length for deep-pocket and hard-to-reach features
• Solid carbide construction delivers rigidity and wear resistance compared to HSS tooling
• Center-cutting capable, allowing plunge entry into workpieces
• Bright uncoated finish suitable for aluminum where certain coatings can cause material adhesion

Compatibility

Designed for use in standard 1/4-inch straight cylindrical shank tool holders, ER collet chucks, and end mill holders on vertical machining centers and CNC routers. Part of the Helical Solutions End Mills for Aluminum 3-Flute Square 45-degree Helix Reduced Neck series.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked state before changing tooling. Confirm proper collet size and torque the tool holder to the machine manufacturer's specification using the appropriate spanner wrench. Verify runout with an indicator after installation to confirm seating before beginning a cut.
