5、o produce holes since the dawn of recorded history.In recent times a flat drill commonly called a spade drill,has been used for producing larger size holes.Generally above 26mm diameter.The type of spade drill presently in use was first introduced commercially in 1945 and was called a“Z”type.In 1947
6、 a three hole blade,called“X”type,and a single bolt hole,called“Y”type,spade drills were introduced.During 1948 a second concern introduced a two bolt hole design along with a single bolt hole design that was not completely compatible with the other single hole blade.This situation did not create a
7、problem as long as there were very few producers of spade drills.During the next two decades the use of spade drills increased along with the number of suppliers.A Depart-ment of Commerece report in 1965 stated that there were 42 suppliers of spade drills.There was much confusion among users regardi

9、or Spade Drill Blades and Spade Drill Holders.The first meeting of TC-18 was held in April 197 1.Because the two hole,three hole,“Z”,and other types of spade drills were not universally used it was decided that only the single bolt hole spade drill blade and holder would be considered for this stand
