have been used to 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 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 othersingle hole blade This situation did not create aproblemaslong as there were very few producers of spadedrills During the next two decades theuse of spade drills increased along with the number ofsuppliers A Department of Commerece report in 1965 stated that there were 42 suppliers of spade drills There was much confusion among users regarding interchangeability between the different types and betweenthe same types of spade drill blades and holders from thevarious suppliers Technical Committee 18 was established during the 1970 Annual Meeting of the American National Standards Institute Committee B94 to develop an American Standard for Spade Drill Blades and Spade Drill Holders The first meeting ofTC-18 was held in April 197 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 standard The draft of the completed standard for Spade Drill Blades and Spade Drill Holders was submitted to the Secretariat, TheAmerican Society of Mechanical Engineers, for review in June 1974 This document was adopted as an American National Standard on September 10, 1975 iii Copyrighted material licensed to Stanford University by Thomson Scientific (www.techstreet.com), downloaded on Oct-05-2010 by Stanford University User No further reproduction or

less than one inch) [Do not interpolate] E X P L A N A T I O N OF SPADE DRILL COMPONENTS as shown in Figure The blade and bladeholdermust be compatible for Type I and Type I1 designs Series A (1 “ to 1%‘’ diameter range) Spade drill blades differ in thickness between Type I and Type I1 and therefore, can not be adapted or modified to be interchangeable with the same spade drill holder Included Angle of Spade Drill Blades The included angle “G” of the spade drill blade can vary depending on material being machined and also application “G”, as noted, is the accepted standard for general purpose application Locating Ear Length The length of the locating ear “F” is a maximum dimension as specified The length of this ear should, of course, not be so long as tointerferewiththe spade drill holder Length of Spade Drill Blade The length of the spade drill blade “E” is given as the most common length supplied Allowance is made for regrinding Longer spade drill blades can often be obtained However, care should be taken not to extend the cutting edge of the spade drill blade so far from its support at the spade drill holder that rigidity and performance are seriously reduced Explanation of Type I and Type II Spade Drill Blades Spade drill blades have been accepted by industry manufactured to two different standards as noted by the asterisks in the charted technical data These two standards are basically different in the area of the hole location “A” and size of hole “D” Some suppliers of spade drill blades manufacture themwiththe key hole design to encompass both Type I and I1 as shown in Figure Some suppliers of spade drill blades furnish them with one large hole to encompass both hole locations Retaining Screw Size of the spade drill blade retaining screw is at the option of the supplier The screw (usually a socket head cap screw) should not be so large as to interfere with the retaining screw hole in the spade drill blade I7 Copyrighted material licensed
