Depths available[edit]
I see a contradiction: The introduction says this is for relatively thin work-pieces, and then the body talks of how one can get 12" deep hole-saws, and how a diamond one can cut arbitrarily far if you break off the core periodically. Pruss (talk) 14:35, 8 March 2012 (UTC)

Advantages[edit]
A hole saw with a pilot but can be used to create a clean hole on both sides of a workpiece without needing a sacrificial backup. When the pilot bit breaks through the material the pilot hole can be used to restart drilling from the other side, thus avoiding breakout on the "back" side. It also extends the drilling depth somewhat since the pilot bit extends beyond the annular ring. — Preceding unsigned comment added by RegulatorRectifier (talk • contribs) 20:32, 15 December 2014 (UTC)
