Accord Services Corporation Releases Drills

January 1, 2002
Accord Services Corporation, released John Henry Carbide Surveyor’s Drills. The drills, John Henry and John Henry Jr., were designed by a surveyor and manufactured specifically for surveyors. Both drills use carbide bits for long life and fast drilling into hard rock. Both drills also feature quick-change bits and will interchangeably accept bits ranging in size from 3/8" to 5/8" in diameter. The John Henry is designed for drilling holes 1/2" and larger. John Henry Jr. is designed for holes from 3/8" to 1/2". Field tests with John Henry have demonstrated that a 1/2" hole in granite can be drilled to a depth of 5/8" in less than two minutes.
