Gws 420715 Combo Drill Reamer 3/16 Inch Solid Carbide

Product Description

The GWS 420715 is a combo drill reamer designed to drill and ream in a single operation, reducing the number of tool changes required during machining. Built from solid carbide, this tool delivers the rigidity and wear resistance needed for precision hole finishing in metalworking and fabrication environments. The reamer diameter is 3/16 inch (0.1875 inch decimal), with a 1-1/2 inch flute length and a 6 inch overall length. The straight shank measures 3/16 inch in diameter. Right-hand spiral and right-hand cutting geometry are standard. Machinists and tool-and-die technicians are the primary users of this type of cutting tool.

This combo drill reamer is suited for production machining, job-shop fabrication, and precision drilling applications where a finished bore is required in one pass. It is commonly used on CNC machining centers, manual mills, and drill presses working with ferrous and non-ferrous metals. The bright uncoated finish makes it appropriate for applications where coating buildup or heat interference with certain materials is a concern. Typical use cases include through-hole and blind-hole finishing where tight diameter tolerances are required.

Key Features

• Solid carbide construction provides rigidity and extended tool life compared to high-speed steel alternatives
• Combo drill-and-ream design completes drilling and reaming in one operation
• Right-hand spiral and right-hand cutting direction for standard machining setups
• Bright uncoated finish suitable for a wide range of base materials
• Straight shank for compatibility with standard collet and chuck systems
• 3/16 inch reamer diameter with 0.1875 inch decimal equivalent for precise sizing

Compatibility

Designed as an OEM-style replacement or standard tooling addition for machining setups requiring a 3/16 inch combo drill reamer with a straight shank and solid carbide construction.

Installation Notes

This tool is installed by machinists in collet chucks or drill chucks rated for the 3/16 inch straight shank diameter. Ensure the machine spindle and workpiece are properly secured before operation. Tool runout should be checked and minimized to maintain reaming accuracy and tool life. Follow standard shop safety practices and applicable OSHA machining guidelines when operating cutting tools at speed.
