Alpha Onsite+ Step Tip Holesaw Arbor — 32–250mm (Large)
Part No: ARBST-2 | Barcode: 9313601025053 | Product Group: ARBST
The Alpha Onsite+ ARBST-2 is a large holesaw arbor for 32–250mm bi-metal holesaws, fitted with the patented 6.35 × 115mm Step Tip HSS pilot drill. The 7/16″ hex shank seats in a 13mm (1/2″) chuck to transfer the strong torque large holesaws demand, while the step-tip pilot starts big holes accurately without pre-drilling.

Key Features & Benefits
- Patented Step Tip pilot drill — starts large holes accurately with no pre-drilling; the stepped tip runs cooler and stays sharper.
- Suits 32–250mm holesaws — covers the large end of the range for big pipe, duct and service penetrations.
- 7/16″ hex shank — grips firmly in a 13mm (1/2″) chuck for the high torque large holesaws need without slipping.
- Fully ground premium M2 HSS — long-life pilot that holds its edge through demanding large-diameter cutting.
- Round, accurate, burr-free holes — step-tip geometry keeps big holesaws tracking true from the start.
When to Use This Product
Use the ARBST-2 to drive large 32–250mm bi-metal holesaws in a 13mm (1/2″) drill — for big pipe, duct, downlight and service-penetration holes. Choose the ARBST-2 (fixed hex shank) over the ARBST-3 (quick-release) when you want a direct, solid drive for heavy cutting; choose the ARBST-3 if you swap holesaws often.
