Pilot Drills and Arbors

Holesaw pilot drills and arbors are integral components when utilising a holesaw and can come in different sizes and materials. The combination of both ensures precise alignment and stable cutting, leading to cleaner and more accurate holes. A pilot drill is mounted in the centre of the holesaw and is used to create a starting point for the hole saw cutting. Its purpose is to accurately position and stabilise the holesaw and serve as a guide to prevent wandering. The arbor is what holds the holesaw in place and connects it to the power tool.

Alpha has a range of different holesaw pilot drills and arbors to choose from ranging in different sizes and materials including Bi-Metal or TCT.

There are two options in our arbor selection: the single arbor package which features an HSS pilot drill designed for bi-metal holesaws, or the Bi-Metal and TCT Arbor Set featuring one arbor and two pilot drills suitable for both bi-metal and TCT holesaws.

Pilot Drills are also available individually, offered in both HSS and TCT, with various sizes to accommodate different needs. Our HSS Pilot Drills cater to all holesaws suited for steel, wood and plastic. Our TCT Pilot Drills are tailored exclusively for our TCT Holesaws and are suited for fibre cement sheeting, ceramics, wall tiles and soft stones.

Additionally, Alpha stocks a range of Pro Lock products which offer a secure and fast way for holesaw changes. The unique Pro-Lock Arbor System streamlines holesaw changes to just seconds and eliminates jamming, thanks to the quick-release design.
The Pro Lock Fast Change System comes with purpose-built pilot drills and different arbor sizes to suit a range of applications. We have also developed a trade-specific version, the Pro Lock Electrician’s Fast Change Arbor Kit which features a dual adaptor to help accurately enlarge downlight holes.

Alpha offers a wide range of holesaw products that include Bi-Metal Holesaws, TCT Holesaws, Hole Cutters, and Annular Cutters, as well as a huge selection of sets and kits tailored to suit the needs of professionals across various industries and trades.
