star 4.1Design 4.4 Tests Star drills shallhavefour cutting edges at oneend for use in drilling holes in brick, tile, concrete, and stone and a struckface on the opposite end to be struck by a ball peen,hand drilling, or engineer's hammer of the appropriate type and size The appropriate size hammershallhave a striking face notlessthan 0.375 in (9.53 mm) larger than the diameter ofthe struck face of the star drill Star drills may be relieved fromthe cutting edges to permit ejection of dust and debris fromtheholebeing drilled Many tests required herein are inherently hazardous, and adequate safeguards for personnelandproperty shall be employed in conducting suchtests 4.4.1 General Star drills shall be testedandshall in conform to the requirements ofthetestsspecified paras 4.4.2 and4.4.3 Separate (new) samples shall be used for each ofthe tests Failuretomeetthe requirementsof either ofthetestsindicatesthe star drills are not in compliancewiththis Standard 4.1.1 The struck face of the star drillshallhave a convex shape or a flat surface 4.4.2 Hardness Determination Test.Hardness determinations with respect to cutting edges and struck faces shall be made on a fixtured tool or on a suitable mounted or unmountedspecimenthat has been cut from the tool using the wet-abrasive or other equivalent method Any hardness test that utilizes equipment and methods equivalent to Rockwell hardness determination as specified in ASTM E 18 willbe acceptable 4.1.2 The struck face shallhave a chamfer of approximately 45 deg or equivalent radius all around the perimeter withthelesserwidth (Fig 1) equal to approximately one-tenth the body stock size For example, if the body stock size equals 1.00 in (25.4 mm), the lesser chamfer width (Fig I ) should equal approximately 0.100 in (2.54 mm) 4.4.3 Impact Test There shall be no chipping, spalling, or cracking of the cutting edge or struck face and no bending of the star drill when tested according to the followingprocedure.Normaldeformation at either endispermitted.' the The star drill shall be mountedverticallywith cutting edges resting on solid concrete The struck face of the star drill shall be struck repeatedly by a hammer ofthe appropriate typeand size [see para 5(c)] until a hole ofnot lessthan 0.50 in (12.7 mm)in depth hasbeenattained The star drillshould be rotated slightly after each successive hit Three holes shall be drilled 4.1.3 All star drills shall be free of nonfunctional sharp edges, points, and surface roughnessthatcould inflictpersonalinjury to theuser 4.2 Materials 4.2.1 Star drills shall be madefrom special-quality, fine grain, hot-rolled or cold-rolled carbon or alloy steel bars, or from an equivalent material, having good wear-resistingand shock-resisting qualities and conforming to anyofthe following standards: ASTM A 29lA29M, ASTM A 322, ASTM A 33 1, ASTM A 576, or ASTM A 681 SAFETYREQUIREMENTS AND LIMITATIONS OF USE 4.2.2 Star drills shall be free from such manufacturingandmaterial defects as seams, laps, pipes, cracks, and cold shuts that would jeopardize sound construction They shall conform to the requirements for mechanical propertiesspecified in para 4.3 andshallwithstand the striking testspecified in para.4.4.3 (a) Star drills are special-purpose tools designed and intendedonly for the drilling ofholes in brick, tile, concrete, and stone (6) A hammer blow shouldalways be struck squarely with the hammer face parallel with thestruck face of the star drill Glancing blows, overstrikes, and understrikes should be avoided 4.3MechanicalProperties 4.3.1 Star drill bevels andtapersshall behardened andtempered to a hardness of not less than53HRC nor more than 60HRC for a distance ofnot less than 0.625 in (15.88 mm)
