Starrett Holesaws

Starretts No. A19 ''Oops'' Arbor, is actually a pilot drill adaptor/arbor that fits in place of the drill in No A1, A2 or A10 regular hole saw arbors. It was created to correct a common mistake. If, for instance, you drill a hole with a 25mm (1'') saw when you intended to use a 50mm (2'') holesaw, the first thing you do is say ''oops'' to yourself. The second thing you would do is to put a 50mm (2'') saw on a No. A2 or No. A10 arbor. Then take the pilot drill out of that arbor. Next, take the ''Oops'' arbor and put the 25mm (1'') saw on it and insert the 6mm (1/4'') shank of that arbor in the drill hole of the No. A2 or No. A10 arbor. The 25mm (1'') saw will now pilot everything while the (2'') saw cuts the proper hole. The `Oops` Arbor also comes in handy in an old house when you need to increase pipe opening holes.

A19 ''Oops'' Holesaw Arbor

The A19 holesaw arbor features an aggressive cutting HSS cutting edge welded to a tough alloy steel body. For use with Arbors A2, A17-12 and XA2.

Starrett Holesaws

Starrett carbide tipped holesaws have a high-hardness and increased resistance to wear this and a triple chip tooth grind, make them ideal for use on PVC, wood, fibreglass, ABS and materials that are too hard and abrasive for regular steel hole saws. The cutting depth is 41mm (1.5/8 inch). The saws have constant 3-pitch teeth.

Holesaw and Arbor sizes:
14-30mm - use Arbor K1 or K4.
32-210mm - use Arbor K2 or K10.
