Enhanced Performance with Spyder 600044 Rapid Eject 4 25 Inch - Unleash Speed and Precision! Review

Thing is a beast. Blasted the OSB subfloor and concrete slab like they were nothing. I also chewed on my thick ceramic tile quite a bit, but decided to save it for the future and finish the job with a chisel.

Hold it firmly instead of pressing on…
