Accupro 95171819 Square End Mill 1/4 in 2 Flute Carbide Zrn

Product Description

The ACCUPRO 95171819 is a solid carbide square end mill designed for high-performance milling in demanding shop environments. Built from micrograin carbide and coated with a ZrN (zirconium nitride) finish, this end mill delivers extended tool life and reduced friction across a range of workpiece materials. It runs a 45-degree helix angle with two right-hand spiral flutes, producing smooth chip evacuation and consistent surface finishes. The centercutting geometry allows plunge milling in addition to standard peripheral and slot cuts. With a 0.25-inch cutting diameter and 0.375-inch length of cut, it is sized for light to medium material removal in precision applications.

This end mill is suited for CNC machining centers and manual mills in job shops, tool rooms, and production environments. The extended reach configuration, with a 1.125-inch reach length and 2.5-inch overall length, accommodates pockets and features that require clearance beyond standard short-reach tooling. The single-end design and right-hand flute direction make it a straightforward drop-in for standard ER or end mill holders.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• ZrN coating reduces friction and extends tool life in ferrous and non-ferrous materials
• 45-degree helix angle promotes smooth cutting action and efficient chip removal
• Centercutting geometry enables plunge entry without a pre-drilled hole
• Extended reach at 1.125 inches for deep pocket and cavity work
• Right-hand cut, right-hand flute — compatible with standard CNC and manual mill setups

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for standard 1/4-inch end mill holders and collet chucks on CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by machinists and CNC operators using standard end mill holders, collet chucks, or shrink-fit tooling. Ensure the holder bore and collet are clean and undamaged before seating the shank. Verify runout with a dial indicator after tightening to minimize premature edge wear. Follow machine manufacturer torque recommendations for set screws or collet nuts — do not overtighten.
