Sgs 74201 Solid Carbide Countersink 1/8 in 90 Degree

Product Description

The SGS 74201 is a single-flute solid carbide countersink designed for precision chamfering and countersinking operations in demanding materials. Built with a 90-degree included angle and a 1/8 inch head diameter, this tool delivers clean, accurate seat geometry for fastener heads and deburring applications. The straight cylindrical shank measures 1/8 inch in diameter and the overall length is 1.5 inches. Solid carbide construction provides the rigidity and wear resistance needed when working with hard or abrasive materials. The bright, uncoated finish is suited for applications where coating buildup could affect dimensional accuracy. Installed by machinists, tool and die technicians, and maintenance professionals using standard drill presses or CNC machining centers.

The SGS 74201 is rated for use across a broad range of material types including steel, stainless steel, cast iron, titanium, high-temperature alloys, non-ferrous metals, composites, and plastics. Its compact 1/8 inch cutting diameter makes it appropriate for small-fastener countersink work, precision instrument components, and tight-tolerance assemblies where a larger tool would not fit. The single-flute geometry helps control chip evacuation and reduces chatter in difficult materials. This tool is sold individually and is suitable for both production and maintenance shop environments.

Key Features

• Solid carbide construction for superior rigidity and wear resistance in hard and abrasive materials
• 90-degree included angle for standard fastener head seating and chamfering
• 1/8 inch head diameter and 1/8 inch maximum cutting diameter for small-fastener and precision work
• Single-flute design promotes efficient chip evacuation and reduces chatter
• Bright uncoated finish maintains dimensional accuracy across a wide range of materials
• Straight cylindrical shank for direct chuck or collet mounting

Compatibility

Designed for use in steel, stainless steel, cast iron, titanium, high-temperature alloys, non-ferrous metals, composites, and plastics. Compatible with standard drill chucks and collet holders accepting a 1/8 inch straight shank.

Installation Notes

Install in a drill press, mill, or CNC machining center using a chuck or collet sized for a 1/8 inch shank. Secure the workpiece firmly before operation and confirm spindle speed is appropriate for the material being cut. Solid carbide tooling is brittle and should not be subjected to side loads or impact forces. Inspect the cutting edge for chipping before each use and replace if damage is observed.
