The Holesaw Arbor Hex Shank is a 11mm hex shank arbor supplied with a pilot drill, designed for use with 14mm to 30mm diameter holesaws on standard hex shank drills and impact drivers. The hex shank provides a secure, non-slip connection between the drill and the arbor at the torque levels generated by small diameter holesaws on wood, plastic, and metal. Supplied with a pilot drill already fitted, it is ready to use straight from the packaging without requiring a separate pilot drill purchase. For electricians, plumbers, and joiners who use smaller diameter holesaws regularly, this arbor covers the full 14mm to 30mm range from a single purchase.

Who Is This For?
The Holesaw Arbor Hex Shank is aimed at electricians, plumbers, heating engineers, and general construction trades who regularly use small diameter holesaws in the 14mm to 30mm range on hex shank drills and impact drivers. It suits the electrician cutting small cable entry points through plasterboard and timber, and the plumber cutting pipe penetrations through joists and panels on first and second fix work.
Typical Applications
-
Fitting small diameter holesaws for cable entry point cutting on electrical first and second fix
-
Cutting small pipe penetrations through timber joists and plywood panels on plumbing installations
-
Cutting conduit entry holes through plastic trunking and electrical enclosures
-
Cutting small ventilation and grille apertures through plasterboard and MDF panels
-
General small diameter hole cutting on multi-trade construction and refurbishment projects
How to Use
-
Thread the holesaw onto the 1/2 inch x 20 TPI arbor thread and tighten firmly until fully seated.
-
Insert the 11mm hex shank into the drill or impact driver chuck and lock securely.
-
Position the pilot drill on the marked centre point and begin drilling at low speed.
-
Apply steady forward pressure once the pilot drill has penetrated and the holesaw teeth contact the surface.
-
Withdraw periodically to clear debris from the tooth gullets on wood and board materials.
-
After breakthrough, reverse the drill briefly to loosen the plug before removal.
Safety
-
Eye protection to EN 166 is mandatory for all hole sawing operations.
-
Secure the workpiece firmly before cutting to manage breakthrough torque.
-
Never exceed the drill manufacturer's recommended speed for the holesaw diameter in use.
-
Locate concealed services before cutting through walls, floors, or ceilings.
Maintenance
-
Remove the holesaw from the arbor after each use and clean debris from the thread.
-
Inspect the pilot drill for wear or damage before each use and replace when blunt.
-
Apply a light coat of machine oil to the thread before storage.
-
Replace the pilot drill independently rather than replacing the full arbor when wear occurs.
Frequently Asked Questions
Q: What size holesaws does this arbor fit?
A: This arbor fits holesaws from 14mm to 30mm diameter with a 1/2 inch x 20 TPI thread. For holesaws above 30mm, a larger arbor with the appropriate thread is required.
Q: Does this arbor fit an SDS drill?
A: No. This arbor has an 11mm hex shank for use with hex shank drills and impact drivers. For SDS drills, use a dedicated SDS arbor.
Q: Is the pilot drill replaceable?
A: Yes. The pilot drill fits independently into the arbor and can be replaced when worn without replacing the full arbor, which reduces ongoing consumable cost.
Q: Will this arbor fit my bi-metal holesaw?
A: Yes, provided the holesaw has a 1/2 inch x 20 TPI thread and is between 14mm and 30mm in diameter. Confirm the thread specification on your holesaw before ordering.
Q: Can I use this arbor with an impact driver?
A: Yes. The 11mm hex shank is compatible with standard impact drivers. For heavy or sustained hole sawing on dense materials, a standard drill with torque control is recommended over an impact driver to protect the pilot drill and arbor thread.
Q: Why should I order from CMT Group?
A: CMT Group has supplied UK construction sites since 2010 with next working day delivery, a FORS Silver accredited fleet covering 90% of the UK mainland, and the EDGE portal for agreed contract pricing and live delivery tracking.
