Delivery Information · Returns & Refunds
Check dimensions, compatibility and the selected pack before adding to your basket.
TIMCO holesaw arbors connect your holesaw to the drill and hold the pilot drill that centres the cut. Choose a hex shank arbor (9.5mm or 11mm) for standard 3-jaw chucks, or an SDS Plus arbor for SDS drills in rotary-only mode. The small arbors suit 14mm to 30mm holesaws (1/2" 20 TPI thread) and the large arbors suit 32mm to 210mm holesaws (5/8" 18 TPI thread). The 300mm hex extension rod adds reach for deep or awkward holes.

Frequently Asked Questions
Which arbor do I need for my holesaw?
Holesaws from 14mm to 30mm need a small arbor (AA4, AA1 or SDSA1). Holesaws from 32mm to 210mm need a large arbor (AA2 or SDSA2).
Is the pilot drill included?
Yes – each arbor is supplied with its pilot drill fitted.
Can I use the SDS Plus arbor in a normal drill?
No – SDS Plus arbors need an SDS Plus chuck. For a standard keyed or keyless chuck choose a hex arbor.
What does the extension rod fit?
The 300mm extension rod fits TIMCO hex shank arbors and goes into a standard drill chuck.
