Micro 100 QDC-2X Combo Drill Countersink No. 2 Solid Carbide

Product Description

The MICRO 100 QDC-2X is a combined drill and countersink tool machined from solid carbide and coated with AlTiN finish for extended tool life in demanding cutting applications. Trade Size 2 with a 3/16 inch body diameter, it produces a 60-degree included angle countersink in a single operation, eliminating the need for separate drilling and chamfering steps. The 5/64 inch drill point diameter and 118-degree drill point angle make it well suited for center drilling and countersinking in ferrous metals, stainless steel, and other hard materials. Right-hand cut geometry. Overall length is 2 inches.

This tool is designed for use in CNC machining centers, manual lathes, and drill presses where center holes and countersink profiles must be cut in a single pass. It is a standard choice for machinists, toolmakers, and precision fabricators working with metal workpieces that require accurately placed center holes or chamfered bolt clearance openings. The AlTiN coating resists heat buildup, making it appropriate for dry or minimum-quantity lubrication cutting environments.
