These Mandrels / Arbors are Professional Tools. This A1 SDS size fits all Hole Saws up to 1 1/8" (30mm) Diameter, they will not only fit our Hole saws but any other manufacturers regular hole saws that use the standard 1/2" thread.

The difference with these Hole Saw Arbors is the fact that the Pilot Drills in the middle are basically Masonry Bits and have Tungsten Carbide Tipped Points

. This makes them perfect for Drilling Tough Abrasive materials like Brick, Marble and Concrete.

There's no Point Having a Hole saw that can cut the Tough Stuff if the Pilot Cannot!!

Pilot Drills are 6mm (1/4") Diameter and are replaceable, these Mandrels can be supplied with regular ends / SDS Plus ends and with HSS Pilots, TCT Pilots or with our special Spear Point TCT Drills especially designed for drilling ceramic tiles without slipping , all available in our store.

These tools are designed to take serious abuse and will outlast conventional tools, they can be used in Corded or Cordless Drills with or without Full Hammer Action. Our TCT (Tungsten Carbide Tipped) are basically regular HSS ( High Speed Steel) Drills with a piece of solid Tungsten Carbide permanently welded into the Tip. As Tungsten Carbide is much tougher than Steel it makes the Drill tougher and able to Drill through much Tougher Materials such as Brick and Masonry without dulling easily.

When used in conjunction with our Tungsten Grit Edge Hole Saws these Mandrels / Arbors leave a fine finish and can cut through a wide range of Tough Abrasive and Brittle materials like Brick, Masonry, Slate, Marble, Construction Materials such as Autoclaved Cement Board, Fibre glass, Composite Boards such as Chipboard and MDF, Laminates, Rubber Tyres, GRP, CFRP, Hardwood Flooring, Laminate Flooring, Plasterboard / Drywall, Soft Resinous Woods and Hard Brittle Materials.
