Sgs 57008 Combo Drill Countersink 3/16 in Solid Carbide

Product Description

The SGS 57008 is a combination drill and countersink tool designed to drill a pilot hole and countersink in a single operation. Built from solid carbide, it delivers consistent performance in ferrous and non-ferrous metals, plastics, and composite materials. The 57008 features a 3/16 inch body diameter, a 5/64 inch drill point diameter, and a 60-degree included angle. Right-hand cut geometry and a bright, uncoated finish make it a reliable general-purpose tool for machine shops, fabrication environments, and production lines where accuracy and cycle time matter.

The SGS 57008 belongs to the Series 301 combo drill countersink line and is suited for use in CNC machining centers, drill presses, and manual lathes. It is a Trade Size No. 2 tool, commonly used for pre-drilling and countersinking fastener seats in medium to light-duty applications. The double-end configuration extends usable tool life by providing two cutting ends per shank, making it practical for high-volume production use.

Key Features

• Solid carbide construction for rigidity and wear resistance
• 60-degree included angle for standard countersink seat geometry
• Double-end design extends tool service life
• Bright, uncoated finish suitable for a wide range of workpiece materials
• Right-hand cut direction compatible with standard spindle rotation

Compatibility

Designed as an OEM-style replacement and standard-fit combo drill countersink for Trade Size No. 2 applications requiring a 3/16 inch body diameter and 60-degree countersink angle.

Installation Notes

Installation of combo drill countersinks should be performed by qualified machinists or tooling technicians familiar with cutting tool setup. Secure the tool firmly in a collet or drill chuck rated for the shank diameter before use. Ensure the spindle is fully stopped before tool changes. Follow machine manufacturer guidelines for appropriate feed and speed parameters for the workpiece material.
