Harvey Tool 11010-C3 Combo Drill Countersink 1/8 in Carbide

Product Description

The HARVEY TOOL 11010-C3 is a combined drill and countersink designed for simultaneous center drilling and countersinking in a single operation. Machined from solid carbide and finished with an AlTiN coating, this tool handles both the pilot hole and the countersink profile without a tool change. The size 00 trade designation corresponds to a 0.0250-inch drill point diameter with a 60-degree included angle. At 1.5 inches overall length and a 1/8-inch body diameter, it fits standard drill chucks and CNC toolholders used in precision machining setups. The 118-degree drill point angle and right-hand cutting direction suit general metalworking and precision shop applications.

This combined drill countersink is used in machine shops, tool rooms, and production CNC environments where center drilling accuracy and countersink geometry must be maintained in one pass. The plain cutting edge style and double end type make it a versatile choice for operators working on small-diameter work requiring precise center location and consistent countersink finish. It is suited for use in lathes, mills, and machining centers handling ferrous and non-ferrous metals where the AlTiN coating provides thermal resistance under higher cutting speeds.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision machining
• AlTiN coating improves heat resistance and extends tool life in dry or high-speed cutting
• 60-degree included angle produces standard countersink geometry for center drilling and chamfering
• 118-degree drill point angle suited for general metalworking materials
• Double end type provides two usable cutting ends per tool
• Right-hand cut compatible with standard spindle rotation on lathes and machining centers

Compatibility

Designed as a combined drill and countersink in size 00 for use with 1/8-inch body diameter toolholders and standard drill chucks in lathes, mills, and CNC machining centers.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Ensure the machine spindle is fully stopped and the tool is secured in a properly sized collet or chuck before operation. Verify spindle rotation direction matches the right-hand cutting orientation of this tool before engaging the workpiece. Refer to the machine manufacturer guidelines and applicable shop safety standards when selecting feeds and speeds for carbide tooling.
