Every drill has a purpose.....on industrial sites, we may need to drill 20mm hole through walls ....so may use a drill such as Bosh GBH with sds bit, heavy drill, but does the business.....putting up a db or control panel, then may use Makita smaller hand drill.....fixing equipment to ceilings/walls by screw, makita impact driver, saves sore hands using pozi drive.
