Starrett KA19 (A19 Oops) Hole Enlargement Arbor
Many tradespeople still know the Starrett KA19 Hole Enlargement Arbor as the A19 Oops Pilot Arbor. It provides a quick and accurate way to enlarge existing holes when using compatible hole saws and arbors.
The KA19 uses a hole saw that matches the diameter of the existing hole. This hole saw then guides a larger diameter hole saw, allowing you to increase hole size accurately and maintain alignment throughout the cut.
As a result, the KA19 offers a simple solution when you need to enlarge a hole that is already cut. Electricians, plumbers, installers and maintenance professionals regularly use this method to correct undersized holes without replacing materials.
The KA19 fits Starrett A1, A2 and A10 hole saw arbors. In addition, it works with Starrett SH Constant Pitch HSS Bi-Metal Hole Saws and DH Dual Pitch HSS Bi-Metal Hole Saws.
