A better way to countersink bridge pins! Here's a unique cutter we've designed to solve bridge countersinking problems.

It eliminates bit chatter, gives you precise, consistent control of the size and depth of cut, and keeps the bevel round, even on a curved bridge surface. You can use it with your hand drill, for cleaner, more professional results.

The Bridge Pin Hole Chamfer Tool gives you much better control than a standard countersink bit. The tool includes a steel pilot for new unreamed 3/16"-diameter bridge pin holes, and another for older bridges that have already been reamed. The pilot keeps the cutter spinning on center, eliminating chatter for a clean cut. An Allen-adjustable brass depth stop controls the cut of the tapered 4-fluted bit. Delrin® lining on the depth stop helps protect the surface of the bridge. When used in a hand drill, the depth stop keeps the cutter perpendicular to the bridge surface, so the countersunk bevel always remains round.

Our thanks to luthier Bryan Galloup for suggesting this great tool!

Instructions and Allen wrench included.

Once I learned how to best use this thing, it worked great. Using as recommended in an electric drill did not leave the pristine holes I wanted. But, using this tool in one of those old time hand crank drills, working very slowly, left crisp, clean, beautiful holes. Would not attempt a bridge pin hole without it now.

If you don't like removing chatter marks from pin hole craters, get one of these. Another amazing tool that makes another annoying task no longer annoying.

This bit does exactly what it is meant to do, elliminates any second guessing, leaves a very clean hole.

Adds a nice touch

This does what it says. It is a must-have if you're making a bridge or if you have to shave an existing one down to the point you need to re-create the chamfers.

Use very light-pressure so the depth-stop doesn't burnish the bridge with a circle!

great tool

This tool makes chamfering bridgepin holes foolproof. You can chuck it in your portable drill to use on bridges that are glued-on, too. Absolutely perfect results. It seems pricey until you realize how much time it saves you.

This is the very best way to make your bridge pins seat perfectly. Works great for making new bridges and also great for re-shaping an old bridge.
