Accupro 95168855 Corner Chamfer End Mill 5/8 in 4 Flute

Product Description

The ACCUPRO 95168855 is a solid carbide corner chamfer end mill designed for precision chamfering and edge-breaking operations on ferrous and non-ferrous workpieces. Measuring 0.6250 inches in diameter with a 4-flute, right-hand spiral configuration, it delivers clean, consistent chamfer geometry at a 45-degree chamfer angle with a 0.0150-inch chamfer width. The AlTiN coating provides elevated heat resistance, extending tool life in high-speed dry or near-dry cutting applications. Micrograin carbide substrate adds toughness and wear resistance at the cutting edge. A variable helix reduces harmonic chatter, improving surface finish in demanding setups.

This end mill suits milling centers and CNC machining operations where edge preparation, deburring, and chamfering are required on precision parts. The extended reach design, with a reach length of 3-3/8 inches and an overall length of 6 inches, accommodates deep-pocket and hard-to-reach workpiece features. The 3/4-inch length of cut and single-end construction make it well suited to production environments where dimensional consistency and tool repeatability are priorities. Machinists running tight-tolerance aerospace, die-mold, or general metalworking programs will find this geometry appropriate for controlled chamfer applications.

Key Features

• Solid micrograin carbide construction for rigidity and extended tool life
• AlTiN coating for high-temperature resistance in dry and semi-dry cutting
• Variable helix geometry reduces chatter and improves surface finish
• 45-degree chamfer angle with 0.0150-inch chamfer width for precise edge preparation
• Extended reach at 3-3/8 inches accommodates deep-pocket and offset features
• Centercutting capability allows plunge entry without a pre-drilled hole

Compatibility

Designed as a direct-fit replacement for standard 5/8-inch shank corner chamfer end mill applications on CNC machining centers and manual mills accepting 5/8-inch tool holders. No specific OEM model compatibility was provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for toolholder torque and runout specifications. Verify holder cleanliness and shank seating before tightening to avoid runout errors that can accelerate edge wear. Confirm spindle direction is set to right-hand rotation before engaging the cut. Always reference the machine control and shop safety procedures when loading or changing cutting tools.
