If the length is only 2", how can cutting depth be 2 3/8"?
Ron W on Oct 5, 2017
BEST ANSWER: The extra 3/8 depth can be achieved because the manufacturer is assuming this hole saw is attached to some kind of an arbor where it will thread on. Bosch uses 2-3/8" as a depth of cut for a wide variety of their holesaws. From 1" to 4 1/2" in diameter
We've got a few Bosch HTC hole saw bits with the quick change mandrel. Will that mandrel fit these bits?

BEST ANSWER: Not all mandrels have the same size and thread, without a model number on the mandrel that you have, I cannot answer this question accurately
