Value Collection 23301 Combo Drill Countersink Size 1

Product Description

The VALUE COLLECTION 23301 is a combination drill and countersink, commonly called a combo drill countersink or center drill, designed to perform two operations in a single pass. It drills a pilot hole and forms a countersink angle simultaneously, reducing setup time and tool changes at the spindle. Trade size 1 with a bright (polished) finish, this tool is used in metal fabrication, machine shops, and general holemaking applications. It weighs 0.14 pounds and ships as a single unit. Machinists, tool and die workers, and maintenance techs working on drill presses or lathes are the primary users of this type of tooling.

Combination drill and countersinks at trade size 1 are suited for light-duty center drilling on lathes and milling machines, as well as countersinking for flat-head fasteners in metalworking and fabrication environments. This tool category falls under holemaking and is classified specifically as a combination drill and countersink. The bright polished finish reduces friction during cutting and allows for visual inspection of the cutting edges. Sold individually, it fits standard toolholders and chucks compatible with size 1 center drills.

Installation Notes

Installation of combination drill and countersinks is performed by machinists or skilled fabricators using a lathe, drill press, or milling machine. Secure the tool firmly in the chuck or toolholder before operation and verify runout before beginning the cut. Always power down the machine and follow lockout/tagout procedures before changing tooling. Do not exceed the recommended RPM range for the material being drilled.
