I've just built a pergola using M8x150 Turbo Coach Screws from
Screwfix. They went straight in to treated softwood using a variable
speed mains drill. I did final tightening (1/2 turn or so) by hand
using a socket & ratchet. No problem there.

My 500w Skill wouldn't have it. What size drill?


. A two speed gearbox driven drill
would probably have coped better.

I'll try with my 700w two speed PP and see what happens. Thanks
