Be clear on how deep you need to drill. These are kind of shallow.
Make sure. You know how deep your a bit will drill. I got this to drill in two by sixes to put these 53 mm round vents in. It will not drill deep enough to even poke the drill bit out the other side so you can flip it over and drill from the other side. Definitely would not have brought this if it was curly advertised.

Holding the Sharpness
While this hole cutter works fairly well it dulls fairly quickly. I bought it to install bird nest vent holes. So i had to buy extra to get the entire job done.

Works well
Bought this to accompany specifically sized vents. Works like a charm.
User
Good buy.
Good bit, spring a little too strong. It will push the wood right out too fast maybe causing back side of wood to splinter.

Works well on 3/4 inch wood
This made in china drill bit worked well with the 53 mm soffit vents. If you have a narrow soffit and need ventilation— look no further
