The Larger A2 Arbor/Mandrel fits all our Tungsten Carbide Grit Hole Saws
from 1 1/4" (32mm) Diameter through to our big 6" (152mm) Diameter and higher.
They come with the standard 5/8" thread and locking pins.
The main difference with these Hole saw Arbor/Mandrels is the fact that the Pilot Drills are basically Masonry Bits
That means they have Tungsten Carbide Tipped Pieces welded into the tips
This means they can drill through hard abrasive products and are designed to be used with a Hammer Drill.
These Mandrel 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.
These Mandrels / Arbors were intended to be used in conjunction with our Tungsten Grit Edge Hole Saws.
