Hi, hammer drill bits: anyone know what the legal definition is if any of the characteristics a drill bit must have to warrant it bieng classed a hammer or percussion bit please?
Hi Did a search on the BSI website and got this: BS2593:1974 Specification for rotary drill rods and tungsten carbide tipped rotary drill bits Doesnt appear to be any others but try it yourself. http://bsonline.techindex.co.uk RSS
dont know but if it isnt an sds drill bit I wouldnt call it a hammer bit .I know some diy drills are percussion type but they call them hammer.To me if it hasnt got sds or + grooves it aint hammer!
