Hertel 300-001001 Combo Drill Countersink Size 00 1/8 in

Product Description

The HERTEL 300-001001 is a solid carbide combination drill and countersink designed to perform center drilling and countersinking in a single operation. With a trade size of 00 and a body diameter of 0.125 inches, this tool is built for precision work in metalworking, machining, and fabrication applications. The 60-degree included angle and plain cutting edge deliver clean, consistent countersink geometry. At 1.5 inches overall length, this compact tool fits standard drill chucks and CNC toolholders. Right-hand cutting direction suits conventional lathe and milling setups. Solid carbide construction provides the hardness and heat resistance needed for high-speed work in ferrous and non-ferrous materials.

This combo drill countersink is used in machine shops, manufacturing, and metal fabrication environments where accurate center holes are required before turning or drilling operations. The double end type extends usable tool life. Typical applications include creating center holes for lathe work, producing countersinks for fastener seating, and spotting holes prior to drilling on mills and lathes. Machinists, tool and die makers, and CNC operators are the primary users of this tool.

• Right-hand cut for use in conventional milling and lathe setups
• Double end design extends tool life by providing two usable cutting ends
• Plain cutting edge style for clean, consistent center holes
• Compact 1.5-inch overall length fits standard toolholders and chucks

Compatibility

Designed as a standard-style combination drill and countersink for use in lathes, mills, and CNC machining centers that accept size 00 center drill tooling with a 0.125-inch body diameter.

Installation Notes

Install in a drill chuck or collet rated for the 0.125-inch body diameter before powering the machine. Ensure the spindle is fully stopped and the machine is in a safe state before loading or removing the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Inspect the cutting ends for chipping or wear before each use, as solid carbide tools can fracture if run with damaged edges.
