Run the pilot hole in first, then reverse the drill operation , on a slow speed when drilling thin plastics.

Mini panels are brilliant for smaller projects. For those who have back problems or are generally not physically strong - I recommend these small panels.

Tried using it on some super soft mild steel, went blunt immediately. Tried running it different speeds too, nothing seems to work. Definitely wouldn't recommend this for steel
I bought 27mm bi metal hole saw this morning 25/8/2021. Used it once to drill 1 hole through 3mm thick mild steel and 3 teeth broke off.- Used generous amount of cutting fluid-Stopped and cleaned shavings off 4 times applied more cutting fluid each time.-Had it on low speed-Had the drill on a torque setting(as show on photo)-downward pressure was just the weight of drill and weight of my hand.Wouldn't recommend this for 3mm thick mild steel.
Purchased to drill through 20mm seasoned hardwood. Drilled 24 holes no problems. You will need the arbor/adaptor which is sold separately
Blunt after drilling 2 holes in colour bond guttering. Had to resort to stitch drilling.
A High Quality Hole Saw, however Bunnings "price match" is a joke..... so I bought elsewhere cheaper....
When I purchased this product online, I thought it included the bit that you inserted in your drill. The description was not clear that it wasn’t. I will need to return it when COVIDSAFE. (Some time in 2025)
Found very useful and friendly to use especially when cutting mild steel.
