Value Collection 157400016000000 Combo Drill Countersink

Product Description

The VALUE COLLECTION 157400016000000 is a combo drill countersink designed to drill a pilot hole and countersink in a single operation. Built from high-speed steel with a bright, uncoated finish, this tool handles both tasks without a tool change. It features a 1/2-inch body diameter, a 3/16-inch drill point diameter, and a 60-degree included angle with a bell-style cutting edge. The right-hand cut and double end type make it a practical choice for machinists, fabricators, and maintenance technicians working with wood, plastic, or soft metals where flush fastener seating is required.

This combo drill countersink is suited for general-purpose countersinking applications in shop and field environments. Trade size 16 and a 3/16-inch point diameter make it appropriate for fastener sizes commonly used in light fabrication and assembly work. The 3-inch overall length fits standard drill chucks on benchtop drill presses and handheld power drills. It is not an aircraft-style tool and is not intended for extended-length or deep-reach applications.

Key Features

• Single-pass operation: drills pilot hole and countersinks in one step
• High-speed steel construction for durability across a range of workpiece materials
• Bell cutting edge style with 60-degree included angle for consistent countersink geometry
• Right-hand cut, double end type for standard rotational drilling setups
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy
• Compact 3-inch OAL fits standard drill chucks without extension

Compatibility

Designed as a general-purpose combo drill countersink for use in standard drill press or handheld drill applications requiring trade size 16 countersinking.

Installation Notes

Installation is performed by machinists or general tradespeople using a drill press or handheld power drill with a standard chuck. Secure the workpiece firmly before drilling to prevent movement during the combined drilling and countersinking operation. Use appropriate cutting fluid when working with metals to extend tool life and maintain cut quality. Inspect the cutting edges before use and replace the tool if chipping or wear is observed.
