Spyder 1 3/8 in Bi-Metal Hole Saw

The Spyder 600072CF hole saw is built for tradespeople and DIY users who need clean cuts in mixed materials. Its bi-metal teeth handle wood, metal, plastics and composites as well as masonry, making it a versatile choice for electrical, plumbing and renovation work.

1 3/8 in diameter with 4/6 TPI

The 1 3/8 in saw diameter and 4/6 variable tooth pitch give fast material removal in wood and controlled cutting in thinner metals. Maximum cutting depth reaches 1 7/8 in, so deep studs or joists are within reach. The saw is not impact rated, so it should be used with standard drill drivers rather than impact tools.

Arbor sold separately with 3/8 in thread

The 3/8 in -20 thread and 3/8 in shank fit common arbors, but no arbor or pilot drill is included in the package. Users must supply a compatible arbor and a 5/16 in by 4 in pilot drill to complete the setup. This keeps the initial cost lower for buyers who already own the required mandrel.

Questions about this item

Will the 1 3/8 in bi-metal hole saw fit the 3/8 in shank arbor I already own?

Yes, the 3/8 in shank size matches a standard 3/8 in -20 thread arbor, so your existing arbor will accept this saw.

How do I confirm the 4/6 TPI tooth pattern is cutting cleanly in metal and wood?

Check for steady chip ejection, minimal vibration and a smooth kerf edge at the rated 1 7/8 in depth across metal, wood and plastics.

Does the box include the 5/16 in pilot drill or must I buy it separately?

The pilot drill is not included; only the bi-metal hole saw body is supplied, so purchase a 5/16 in x 4 in pilot drill and a compatible arbor separately.
