These twist drills are excellent for drilling the mortise hole in the pipe shank where the tenon of the pipe mouthpiece is inserted. All our mouthpieces with an integrated tenon fit perfectly, as well as all our tenons with a diameter of 10.5 mm.

We offer the drills in three different diameters. With a diameter of 10.2 mm, the tenon fits very tightly; with 10.3 mm, it fits "medium tight"; and with 10.4 mm, it fits a bit looser.
