Osg 404-1000 Square End Mill 1in 4-flute Solid Carbide

Product Description

The OSG 404-1000 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. Built from micrograin carbide, it delivers the hardness and wear resistance needed for demanding cutting applications. The tool features a 1 inch cutting diameter, a 1-1/2 inch length of cut, and a 4 inch overall length with a 1 inch shank diameter. Its 30-degree helix angle and spiral flute geometry promote efficient chip evacuation and stable cutting performance. This is a single-end, uncoated tool intended for right-hand cut and right-hand flute configuration. Machinists and CNC operators working in job shops or production environments are the primary users.

The 404-1000 is suited for face milling, slotting, profiling, and peripheral milling operations on a range of workpiece materials. Its centercutting capability allows plunge cutting directly into material without a pre-drilled hole. The regular-length body and standard 1 inch shank make it compatible with common toolholders and collet systems used in vertical and horizontal machining centers. It is appropriate for both conventional and climb milling strategies depending on machine rigidity and material requirements.

Key Features

• 1 inch cutting diameter with 1-1/2 inch length of cut for substantial material removal
• 4-flute configuration for improved surface finish and feed rate capability
• Micrograin solid carbide construction for hardness and edge retention
• 30-degree helix angle promotes smooth cutting action and efficient chip flow
• Centercutting design allows direct plunge entry into workpiece material
• Right-hand cut, right-hand flute spiral geometry for standard CNC milling setups

Compatibility

Designed as an OEM-style replacement and standard tooling option for machining centers and manual mills equipped with toolholders accepting a 1 inch straight shank, consistent with OSG Series 404 end mill specifications.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully within a properly sized collet, end mill holder, or hydraulic toolholder before operation, and verify runout with an indicator before cutting. Ensure the machine spindle is completely stopped and locked out before changing or adjusting tooling. Follow the machine manufacturer and OSHA guidelines for personal protective equipment and guarding during milling operations.
