Tutorial OnShape Holes By: Matthew Jourden Brighton High School Brighton, MI Holes Types: Simple: Single drill Thru a part either all the way or part way Counterbore: Two different diameter holes that are concentric used with bolts to pass thru. - Large hole is drilled vertically to a depth to provide a flat surface for a bolt head to rest on. The large hole maybe drilled deep enough to hide the entire bolt head below the finished surface. - Small hole will go thru the rest of the part for the shaft of the bolt to pass through and connect to a second part. Countersink: Two different concentric holes used with machine screws. - Large hole is tapered from the face of the part down to the small. Depth of large hole is based on the angle of taper, w hich will be determined by the fastener being used. - Small Hole
