Hey miller and kdv, thanks for ur reply. I was a lil worried cause if u try to release or tighten by holding the trigger its nit great an makes a sound like its not supposed to be done like that. I will have ti vet used to the new system. In the long run I can see it is better an will hold the bits alot bettwr. Hey Carl. Ye im a plumber. Am 33 and veen plumbin for around 7 years. Been using companies drills for awhile but they pretty shit and wantedy own stuff for private work so have started get my own gear. Am lookin at a cordless sds next, thinking of treating myself to fuel m18 just need to decide which one, therss a 26mm in concrete an 28mm in concrete so wanna chexk out size diff. Tryin to keep the amount of drills I have dowb so my combi will be used up to 10mm and then 15mm and up sds.
