Helical Solutions 87682 Corner Rounding End Mill 5 Flute Carbide

Product Description

The HELICAL SOLUTIONS 87682 is a solid carbide corner rounding end mill designed to produce consistent radius profiles on workpiece edges. With a 0.25-inch radius and a 0.75-inch mill diameter, this single-end tool generates smooth, accurate corner breaks on ferrous and non-ferrous materials. The 5-flute helical design improves chip evacuation and surface finish compared to lower-flute-count alternatives. An APLUS coating is applied to the cutting surfaces to extend tool life and reduce friction at elevated cutting speeds. It is installed in CNC machining centers and manual mills by machinists and toolroom professionals.

This end mill is suited for production and job-shop environments requiring repeatable edge-rounding operations on milled components. The 0.75-inch cylindrical shank fits standard ER or end mill holders used in vertical and horizontal machining centers. The right-hand flute direction and right-hand cut geometry are compatible with conventional CNC spindle configurations. Typical applications include edge preparation on structural components, mold and die work, and part finishing where a precise radius is required before assembly or coating.

Key Features

• 0.25-inch corner radius for precise edge-rounding profiles
• 5-flute helical geometry improves chip flow and surface finish
• Solid carbide construction provides rigidity and wear resistance
• APLUS coating reduces friction and extends tool life in demanding cuts
• Single-end design with 3.0-inch overall length and 0.75-inch cylindrical shank
• Right-hand flute direction compatible with standard CNC spindle setups

Compatibility

Designed as a direct-fit replacement for standard 3/4-inch shank corner rounding end mill applications in CNC machining centers and manual mills using ER collet or end mill holder tooling systems.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before mounting or removing the end mill. Use a calibrated torque wrench and the appropriate collet or holder system to secure the shank to the specified clamping specification for your toolholder. Inspect the cutting edges and coating condition before each use and replace the tool at the first sign of chipping or excessive wear.
