Helical Solutions 48136 Square End Mill 1/4 in 3 Flute Carbide

Product Description

The HELICAL SOLUTIONS 48136 is a solid carbide square end mill designed for precision milling operations in metal, alloy, and composite workpiece materials. It features a 1/4 inch mill diameter, a 1 inch length of cut, and a 3 inch overall length with a straight cylindrical 1/4 inch shank. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces at the tool tip. A Zplus coating provides surface hardness and heat resistance, extending tool life in demanding cutting environments. This end mill is single-end and centercutting, making it suitable for plunge entry as well as peripheral and slot milling passes.

This end mill is intended for use on CNC machining centers and manual mills in job shop, production, and toolroom settings. Its 3-flute geometry balances chip clearance with rigidity, making it a practical choice for aluminum, non-ferrous metals, and select ferrous alloys. The variable index design reduces harmonic chatter during high-speed passes. Machinists, CNC operators, and tool-and-die professionals are the primary users. It is well suited for finishing and semi-finishing operations where dimensional accuracy and surface finish are critical.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision milling
• 40-degree helix angle promotes effective chip evacuation and smooth cutting action
• Zplus coating adds surface hardness and thermal resistance to extend tool life
• Variable index flute spacing reduces chatter and improves surface finish quality
• Centercutting geometry allows direct plunge entry into workpiece material
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual milling machines accepting a 1/4 inch straight cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully within the tool holder collet to the recommended engagement depth before tightening. Verify spindle speed, feed rate, and depth of cut parameters against the tool manufacturer guidelines before initiating a cut. Inspect the cutting edges for chips or wear before each use and replace the tool if edge condition is degraded.
