Accupro 95168791 Corner Chamfer End Mill 1in 4 Flute Carbide

Product Description

The ACCUPRO 95168791 is a solid carbide corner chamfer end mill designed for high-performance milling of chamfered edges and beveled profiles in ferrous and non-ferrous materials. It features a 1 inch cutting diameter and a 45-degree chamfer angle with a 0.0200 inch chamfer width, producing clean, consistent edge breaks in a single pass. The four-flute, single-end design with a variable helix spiral flute geometry reduces chatter and improves surface finish in deep pocketing and long-reach applications. A nACRo coating provides elevated heat and wear resistance, extending tool life in demanding cutting conditions. Machinists and tool-and-die professionals working with CNC machining centers are the primary users of this tool.

This end mill suits long-reach chamfering operations where standard-length tools cannot reach. The 3.25 inch length of cut and 6 inch overall length make it suitable for deep cavity work and multi-step part features in mold making, die work, and precision component manufacturing. Its centercutting capability allows plunge entry directly into the workpiece. The right-hand flute direction and right-hand cutting direction are standard for conventional CNC vertical and horizontal machining setups.

Key Features

• Solid carbide micrograin construction for rigidity and edge retention at high feed rates
• nACRo coating for improved wear resistance and reduced heat buildup in the cut zone
• Variable helix geometry reduces harmonic vibration and chatter during extended-reach cuts
• 45-degree chamfer angle with 0.0200 inch chamfer width for consistent edge preparation
• Centercutting design allows direct plunge entry without pre-drilling
• Long flute length of 3.25 inches supports deep cavity and multi-depth chamfering

Compatibility

Designed as an OEM-style solid carbide chamfer end mill for use in CNC machining centers and manual mills accepting a 1 inch straight shank. No specific compatible machine models were listed in the product data.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the 1 inch shank in a properly sized end mill holder or collet chuck, ensuring full engagement depth per the toolholder manufacturer's specification. Verify spindle runout before use, as excessive runout accelerates wear on carbide tooling. Power down and lock out the spindle before changing or inspecting the tool.
