Drill America DEWPIL3/4X3/16 3/4" X 3/16" pilot for counterbore pneumatic accessory

SKU CH-JRAC-TPW7Y

A 3/16" interchangeable pilot that guides a 3/4" counterbore cutter for pneumatic tools

  • Interchangeable pilot enables flexible counterboring setups
  • Two-piece construction separates shank from cutter for adaptability
  • Integral shank design supports stable spot-facing operations
  • California Proposition 65 notice flags cancer-risk chemical
  • California Proposition 65 notice flags reproductive-harm chemical

Pilot for 3/4" counterbore

This interchangeable pilot fits a 3/4 inch counterbore cutter and has a 3/16 inch shank. It is designed for pneumatic counterboring tools used in metalworking and maintenance tasks. The two-piece construction allows the pilot to be swapped without replacing the entire cutter assembly. It ships new from the manufacturer.

Suited for machinists needing a replaceable pilot

Machinists and maintenance technicians who use 3/4 inch counterbore cutters with a 3/16 inch pilot requirement will find this part compatible. It is not intended for drill presses that require a different shank diameter or for counterbore sizes other than 3/4 inch. Buyers who need a complete counterbore tool rather than just the pilot component should look elsewhere. The product carries a California Proposition 65 warning for cancer and reproductive harm.

Simple pilot swap on compatible cutters

Installation consists of removing the existing pilot from the counterbore cutter and inserting this replacement into the cutter body. The interchangeable design means no special tools are required beyond those used to secure the cutter in the pneumatic tool. The most common issue is selecting a pilot with the wrong shank diameter for the cutter, which prevents proper seating and can cause runout or tool damage.

Questions about this item

What shank diameter must my counterbore cutter have to accept this 3/16" pilot?

The pilot is designed for a counterbore cutter with a 3/16" pilot hole, so the cutter's shank must match that internal diameter for a secure fit.

Can I use this pilot with a counterbore that has a 1/8" spot-face depth?

Yes, the interchangeable pilot works with both shallow spot-facing cuts of 1/8" or less and deeper counterboring operations on the same cutter body.

How do I confirm the pilot is seated correctly after installation?

The pilot should sit flush in the cutter's pilot hole with no wobble, allowing the counterbore to cut concentric to the pre-drilled hole.
