Bosch EXPERT ToughMaterial Hole Saw Set, 5-piece, 68 mm, Power Change Plus

The Bosch EXPERT ToughMaterial Hole Saw Starter Kit (5-piece), 68 mm, Power Change Plus is a 5-piece carbide hole saw set aimed at electricians and installers. It provides the tools needed to cut clean circular openings in heavy-duty structural materials. The set can be used on wood, metal, stainless steel, brick, soft tiles, and fibre-reinforced plastics. Tough cutting edges keep hole quality consistent even when hitting hidden obstacles such as embedded screws. Accurate material removal helps socket housings and plumbing fixtures seat correctly. A compatible power drill is required to drive the set.

A central feature of the kit is the Bosch Power Change Plus mounting system. This set format includes the necessary adapter components to build a complete cutting unit. The quick-change arbor lets users remove the core or swap the saw quickly while work is in progress. This modular design speeds up workflows that require frequent task changes. Built for unpredictable environments, the tooling holds up where base materials are less than ideal. As a passive accessory, the assembly relies entirely on the rotational force of a host tool.

• 68 mm cutting diameter matches the exact cut-out dimensions required for standard socket housings and light switches.
• 60 mm working length penetrates deep wall cavities and thick wood in a single continuous pass.
• 472 g assembly weight maintains rigidity under heavy rotational load without overloading the drill chuck.
• The included pilot drill provides a physical starting point to prevent the main saw from wandering on smooth stainless steel or soft tiles.
• Solid carbide teeth handle highly abrasive substrates such as brick and fibre-reinforced plastic without losing edge sharpness.
