Bosch Professional Holesaw Arbors & Pilot Drills at Tooled-Up.com
Bosch Professional Holesaw Arbors & Pilot Drills connect your drill to a threaded holesaw and keep the cut centred from the first turn. Tooled-Up.com stocks hex shank arbors with pilot drills for 14mm - 30mm and 32mm - 210mm holesaws. It also stocks the EXPERT Power Change Plus system, which includes SDS Plus and SDS arbors as well as standard hex shank versions.
What sets the range apart is how the parts work together. The Power Change Plus arbors allow tool-free holesaw changes. Separate HSS-G and HSS-Co pilot drill bits mean you can replace a worn pilot without buying a whole new arbor. Adapter nut sets and a converting set let you bring existing holesaws into the system.
Key Features of Bosch Professional Holesaw Arbors & Pilot Drills
- Hex shank options: The 11mm hex shank arbors transmit maximum torque and fit three-jaw chucks and ¼" internal hex tool holders. The 8.7mm Power Change Plus arbor and the 9.5mm shank arbor for smaller holesaws suit lighter drilling.
- Power Change Plus quick-change: Swap holesaws without tools, which saves time on jobs that need several hole sizes.
- SDS Plus and SDS shanks: Pair the arbor with a rotary hammer drill for cutting in masonry and other tough materials.
- HSS-G and HSS-Co pilot drills: HSS-G suits general-purpose drilling. HSS-Co is the tougher choice for harder materials, as cobalt gives better heat resistance.
- Extension bar: The hex shank Power Change Plus extension bar adds reach for deeper cuts or awkward access.
- Adapter nuts: The adapter nut set lets you fit different thread sizes to the same arbor.

Frequently Asked Questions
Which arbor do I need for a 50mm holesaw?
Choose an arbor rated for 32mm - 210mm holesaws, such as the 11mm shank arbor and pilot drill or the hex shank version. For holesaws between 14mm and 30mm, use the smaller-range arbors.
What is the difference between HSS-G and HSS-Co pilot drills?
HSS-G pilot drills suit general drilling. HSS-Co contains cobalt, which resists heat better and suits harder materials where a pilot drill wears quickly.
Can I use a holesaw arbor in an SDS drill?
Yes, but you need an SDS Plus or SDS arbor from the EXPERT Power Change Plus range. Hex shank arbors are designed for standard chucks.
Can I replace only the pilot drill?
Yes. Bosch EXPERT Power Change Plus HSS-G and HSS-Co pilot drill bits are sold separately, so you can replace a worn pilot and keep the arbor.
