Osg 403-1719 Square End Mill 0.1719 in 3 Flute Carbide

Product Description

The OSG 403-1719 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 0.1719-inch (11/64-inch) cutting diameter and three flutes, it delivers a balance of chip clearance and cutting edge strength suited to finishing and light roughing passes. The 30-degree helix angle promotes smooth cutting action and efficient chip evacuation. The bright, uncoated finish makes it well suited for use on a wide range of work materials where coating-related dimensional concerns are a factor. It is installed and operated by machinists and CNC tooling technicians.

This end mill fits standard milling and CNC machining center applications where small-diameter tooling is required. The 0.1875-inch (3/16-inch) shank diameter allows it to seat in standard collets and end mill holders. With a 0.625-inch length of cut and a 2-inch overall length, it is dimensioned for regular-reach work in slots, pockets, profiles, and contour milling tasks. The right-hand cut and right-hand spiral flute configuration are standard for conventional CNC and manual vertical milling setups.

Key Features

• 0.1719-inch (11/64-inch) cutting diameter for small-feature milling
• Solid carbide micrograin construction for rigidity and wear resistance
• 3-flute geometry balances chip clearance and cutting edge count
• 30-degree helix angle for smooth cut engagement and chip evacuation
• Center-cutting design allows plunge entry
• Bright/uncoated finish — no coating-related dimensional offset
• Right-hand cut, right-hand spiral flute — compatible with standard CNC spindle rotation

Compatibility

Designed for use in standard 3/16-inch collets or end mill holders on CNC machining centers and manual vertical milling machines; part of the OSG Series 403 regular-length solid carbide end mill family.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully and evenly in the collet or holder to the recommended grip length, and torque the collet nut according to the tool holder manufacturer's specifications. Inspect the cutting edges for chips or damage before each use.
