Harvey Tool 11005-C3 Combo Drill Countersink 1/8 in Carbide

Product Description

The HARVEY TOOL 11005-C3 is a combined drill and countersink designed for creating centered starting holes and countersunk profiles in a single operation. Built from solid carbide with an AlTiN coating, this tool delivers high wear resistance and heat tolerance in demanding cutting applications. Trade size 000 with a 1/8 inch body diameter, it produces a 60-degree included angle and features a 118-degree drill point angle. Right-hand cut geometry suits standard spindle rotation on machining centers, CNC mills, and drill presses. The 0.020 inch drill point diameter targets precision centering work on small-diameter features.

This combo drill countersink is suited for precision machining environments where accurate center starting and countersinking must be performed in one pass without a tool change. Its compact trade size 000 profile makes it appropriate for small parts, tight tolerances, and applications requiring minimal runout at the tip. Machinists and CNC operators working in aerospace, tool and die, medical device, and general metalworking applications will find this tool effective for maintaining center accuracy before through-drilling operations.

Key Features

• Solid carbide construction for high rigidity and wear resistance in metalworking applications
• AlTiN coating provides elevated heat resistance, extending tool life in dry or high-speed cutting conditions
• 118-degree drill point angle with a 60-degree included angle for precise centering and countersinking
• Trade size 000 with a 0.020 inch drill point diameter targets small-feature precision work
• Right-hand cut, plain cutting edge style compatible with standard spindle rotation
• Double end type with 1-1/2 inch overall length for balanced reach and rigidity

Compatibility

Designed as an OEM-style replacement or production-run tool fitting standard combined drill and countersink toolholding in CNC machining centers, manual mills, and drill presses accepting 1/8 inch body diameter shanks.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Secure the shank fully in a collet or drill chuck rated for the tool diameter before running the spindle. Confirm spindle rotation direction is right-hand before engaging the cut. Inspect the tool tip for chipping before each use, as solid carbide is brittle and sensitive to side-loading or improper runout.
