Sgs 57012 Combo Drill Countersink Size 6 Solid Carbide

Product Description

The SGS 57012 is a combination drill and countersink designed to drill a pilot hole and create a 60-degree countersink in a single operation. Built from solid carbide with a bright polished finish, this tool delivers precise, repeatable results on metalworking applications where clean countersunk holes are required. The 0.5-inch body diameter and 7/32-inch drill point work together to produce a size 6 countersink in one pass, reducing setup time and minimizing the number of tools needed on the bench. The right-hand cut geometry and plain cutting edge style make it a straightforward, reliable choice for machinists and tool-and-die professionals working in production or job-shop environments.

This tool is suited for countersinking operations on metal workpieces in both production and precision machining environments. The double end type provides added value by offering two usable cutting ends before the tool is retired. With an overall length of 3 inches and a drill point length of 1/4 inch, it fits standard drill presses, CNC machining centers, and manual mills. The Series 301 designation places it within SGS's catalog of solid carbide combination tools. It is not an aircraft-style tool and is not a long-length variant, making it appropriate for standard-depth countersinking tasks.

Key Features

• Solid carbide construction for hardness, wear resistance, and dimensional stability under repeated use
• Bright polished finish reduces friction and chip adhesion at the cutting edge
• 60-degree included angle produces standard countersink geometry in a single pass
• Double-end design provides two usable cutting ends, extending tool life between replacements
• Right-hand cut with plain cutting edge style for consistent chip flow in metalworking applications
• Compact 3-inch overall length fits standard spindle setups without extended-reach considerations

Compatibility

Designed as an OEM-style combination drill countersink for use in drill presses, CNC machining centers, and manual milling setups requiring a size 6 countersink with a 0.5-inch body diameter.

Installation Notes

Installation and use of this tool should be performed by qualified machinists familiar with cutting tool setup and machine operation. Secure the tool firmly in the appropriate collet or chuck before operation and verify runout is within acceptable limits for the application. Always power down the machine completely before changing or inspecting cutting tools. Follow the machine manufacturer's guidelines for spindle speed and feed rate when using solid carbide combination tools.
