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.

Holesaws Constant Pitch Carbide Tipped

Starrett Bi-Metal Holesaws Constant Pitch HSS

Bi-Metal Constant Pitch Holesaws have 6 teeth per 25mm/inch with an aggressive cutting action, featuring a HSS cutting edge welded to a tough alloy steel body. The Constant Pitch provides a smooth cut on thinner gauge materials, with minimal tendency to bite or snag on contact with irregular surfaces. Cutting depth 41mm (1 5/8").

Holesaw and Arbor sizes:
14-25mm - use Arbor A4 or K4.
30-210mm - use Arbor A10 or K10.

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.

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.
