Rothenberger 21583 Unidrill Self-Adjusting Hole Cutter 10-28 (3/8-1.1/8)

The Rothenberger 21583 Unidrill Self-Adjusting Hole Cutter is a practical hole cutter with a chrome-plated body and titanium-coated bit, developed for installers working in the plumbing, heating and refrigeration/air conditioning sector to cut additional connection holes in copper and metal pipes.

Burr-Free Drilling and a Depth Stop That Protects the Pipe

Thanks to its special centre drill bit, the Unidrill cuts smooth, burr-free holes in the pipe surface. The drilling depth stop on it prevents the bit from advancing too far and damaging the opposite side of the pipe wall. With the 10, 18, 20, 22, 28 mm and 3/8, 1/2, 7/8, 1.1/8 inch size steps machined into the body, you work with the correct setting on pipes of different diameters, so tee connection and branch holes are prepared quickly.
