Ingersoll Cutting Tools 3207958 Indexable Spotting Drill

Product Description

The INGERSOLL CUTTING TOOLS 3207958 is a single-flute indexable spotting drill designed for precision hole starting in CNC machining and manual drilling operations. Built on the FAK series platform, it features an 82-degree point angle and accepts TFLT 15T308 inserts for repeatable spot geometry without regrinding. The steel body is uncoated and measures 3.5 inches in overall length with a 0.75-inch shank diameter, making it compatible with standard drill chucks and collet systems. This tool targets general-purpose spotting across a broad range of workpiece materials. Machinists and toolroom technicians are the primary end users.

The 3207958 is suited for general-purpose spotting and center-location operations in production and job-shop environments. Its universal workpiece material rating covers cast iron, non-ferrous metals, stainless steel, steel, and superalloys, making it adaptable across common machining applications. The straight-flute, single-flute design promotes clean chip evacuation during shallow spotting passes. Maximum depth of cut is 0.42 inches. No through-coolant is provided, so flood or mist coolant applied externally is the appropriate cooling method for this tool.

Key Features

• 82-degree point angle for accurate spot and chamfer geometry
• Accepts TFLT style inserts, size code 15T308, for indexable cutting edges
• Single straight flute design supports clean chip clearance in spotting operations
• 0.75-inch shank diameter fits standard toolholders and collet systems
• FAK series steel body, uncoated, for general-purpose use across multiple material groups
• Maximum depth of cut of 0.42 inches suits shallow spotting and center-drilling tasks

Compatibility

Designed to accept TFLT style inserts at size code 15T308. Compatible workpiece material codes include H, K, M, N, P, and S, covering cast iron, non-ferrous alloys, stainless steel, carbon and alloy steels, and superalloys.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the 0.75-inch shank in a properly sized collet, drill chuck, or toolholder before operation, and verify runout before engaging the workpiece. Power down the machine and lock out energy sources before changing or indexing inserts. Do not exceed the rated maximum depth of cut of 0.42 inches per pass, and apply external coolant as needed since no through-coolant port is present.
