Klein Tools 31922 – Frequently Asked Questions

1) Does the Klein Tools bi-metal hole saw come with an arbor, or do I need to buy one?
No arbor is included. The Klein bi-metal hole saws are made to run on the Klein Tools arbor, Cat. No. 31906, which is sold separately. If you are buying your first Klein hole saw, order the arbor with it or you will not be able to mount the saw in your drill.
2) Will this hole saw cut stainless steel enclosures, or do I need a carbide cutter?
It is built for exactly that. The bi-metal blade is optimized for cutting steel including stainless, and it cuts precise holes in both stainless and mild steel. It also handles drywall, ceiling tile, laminates, wood and plastic, so one saw covers panel work and rough-in in the same day.
3) How do you get the slug out of a Klein hole saw without wrecking the teeth?
The cup has multiple slots cut into the body that give you different leverage points to pry the slug out with a screwdriver. The hex-shaped base also lets you pull the saw off the arbor by hand or with a wrench instead of fighting a round body.
4) Can I cut a hole in an energized panel with this?
No. Klein's instructions for these hole saws are explicit: never use on or near live electrical circuits. De-energize and verify dead before cutting, wear approved eye protection, and follow the safety instructions in your drill's owner manual.
5) If I buy both the 1-3/8 and 1-3/4 inch Klein hole saws, do I need two arbors?
One arbor covers both. Both the 31922 and the 31928 mount on the Klein Tools arbor, Cat. No. 31906, so a single arbor and pilot bit serves both cup sizes. Swapping is a matter of backing the cup off the hex base.
6) Is this hole saw stiff enough for repeated cuts in electrical panels and strut?
The construction is heavy-duty steel with a thick back plate specifically to take abuse, which is what keeps the cup from flexing or deforming at the mount on repeated metal cuts. Each saw weighs 0.12 lbs.
