Accupro FAT4902000-5 Single Point Threading Tool

Product Description

The ACCUPRO FAT4902000-5 is a solid carbide single point internal threading tool designed for cutting precise thread forms on CNC lathes and manual turning centers. It handles a minimum threading diameter of 0.49 inches with a cutting depth of 2 inches, making it suitable for threading deeper bores where clearance is critical. The 29-degree profile angle is ground for standard thread forms, and the bright uncoated finish maintains dimensional accuracy without the added thickness of a coating layer. Machinists and toolroom professionals use this insert-style bar for production and job-shop threading operations requiring consistent, repeatable results.

This tool is suited for internal threading applications in ferrous and non-ferrous materials where a solid carbide bar provides the rigidity needed to minimize deflection. With a 0.5 inch shank diameter and 3 inch overall length, it mounts in standard boring bar holders and quick-change toolpost systems. The 0.13 inch projection from edge and 0.069 inch flat width are sized for fine to moderate pitch threading. A maximum thread pitch of 5 TPI supports coarse thread production in larger-diameter bores. No coolant-through capability means external coolant delivery should be arranged at setup.

Key Features

• Solid carbide construction provides rigidity and wear resistance for internal threading
• 0.49 inch minimum threading diameter with 2 inch cutting depth for deep-bore applications
• 29-degree profile angle for standard thread form geometry
• 5 TPI maximum thread pitch supports coarse internal threads
• Bright uncoated finish preserves tight dimensional tolerances
• 0.5 inch shank diameter fits standard boring bar and quick-change toolpost holders

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 0.5 inch shank boring bar holders used in CNC and manual turning applications requiring internal threading capability.

Installation Notes

Installation should be performed by a qualified machinist following established lathe setup procedures. Power down and lock out the machine spindle before mounting or adjusting the tool. Verify shank clamping torque using the toolholder manufacturer specifications and confirm tool centerline height before cutting. No coolant-through capability is present, so arrange external coolant delivery before beginning threading passes.
