## Description

The Bosch EXPERT 4 Piece Power Change Plus Hole Saw Converting Set is a keyless arbor conversion system designed to let tradespeople switch hole saws in seconds without tools, screws, or bolts. Conventional hole saw adapters waste time on site — attaching and aligning a hole saw accurately is a fiddly process that slows down even experienced contractors. The EXPERT Power Change Plus system solves this with a one-click mechanism that lets you pull one hole saw out and push another straight in. Despite the speed of the changeover, the connection remains firm, with a reinforced shank and close-fitting guide drill that reduces play compared to standard adapters. The converting set includes two adapter nuts that allow compatibility with standard hole saws across a wide diameter range. The 1/2"-20UNF threaded adapter covers hole saws from 14–30mm, while the 5/8"-18UNF adapter handles sizes from 32–152mm. This makes it a practical solution for electricians, plumbers, and joiners working with a variety of core sizes throughout the day. The pilot drill features an HSS-G construction with a hexagonal 11mm shank, and is also designed to push out cut plugs quickly and cleanly, saving further time on repetitive drilling tasks.
