Accupro 12176783 Corner Radius End Mill 3/8 in 3 Flute Carbide

Product Description

The ACCUPRO 12176783 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 3/8 inch cutting diameter with a 0.06 inch corner radius that reduces stress concentrations at the bottom of a cut and extends tool life compared to a sharp-corner geometry. The 3-flute configuration balances chip evacuation with edge strength, making it suitable for slotting, profiling, and finishing passes. With a 7/8 inch length of cut and a 30-degree helix angle, this end mill provides efficient material removal while maintaining good surface finish. The bright/uncoated finish suits a range of general-purpose machining applications.

This end mill is used in CNC machining centers and manual mills for general-purpose milling work on metals, plastics, and composite materials. The right-hand cutting and right-hand flute direction make it a standard tool for conventional and climb milling on vertical machining centers. The regular length profile and 3/8 inch shank diameter fit standard ER and end mill holders commonly found in job shops and production environments. It is centercutting, allowing for plunge operations when required in the application.

Key Features

• Solid carbide construction provides rigidity and wear resistance for demanding milling operations
• 0.06 inch corner radius reduces tool breakage and improves corner durability at the bottom of a pocket or slot
• 3-flute design balances chip clearance and cutting edge strength for ferrous and non-ferrous work
• 30-degree helix angle promotes smooth cutting action and efficient chip evacuation
• Centercutting geometry allows direct plunge entry without pre-drilling
• Bright/uncoated finish suitable for general-purpose machining applications
• Right-hand cut and right-hand flute direction for use in standard CNC and manual mill setups

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC vertical machining centers and manual mills using 3/8 inch end mill holders or collet chuck systems.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank fully in a clean, properly sized end mill holder or collet, ensuring adequate gripping length to prevent pullout under cutting loads. Never exceed the tool manufacturer's recommended feed and speed parameters for the material being cut. Inspect the cutting edges for chips or wear before each use and replace the tool if damage is observed.
