Blind Hole: A blind hole refers to a hole that is drilled to a specified depth, without breaking through to the other side of the work piece. Bottoming Tap: A type of hand tap that has 1 to 1 1/2 tapered threads and is used to tap to the very bottom of the hole. The bottoming tap is the last tap used in the sequence for blind holes. Clearance Drill Size: The size of the drill required for a given threaded hole. The hole is drilled to this size before it is tapped. Plug Tap: A type of hand tap that has 3 to 5 tapered threads and is often used second in the sequence of hand taps used to tap blind holes. Plug taps can be used in place of taper taps. Straight Handle Tap Wrench: A type of tap wrench often used to hold taps with larger diameters. A straight-handle tap wrench gives more leverage and is easier to turn. T-Handle Tap Wrench: A type of tap wrench often used to hold taps with smaller diameters. A T-handle tap wrench is turned with the palm of the hand and often requires more pressure. Tap Wrench: A type of wrench that holds the square end of a tap in order to turn it. Tap wrenches are also used with hand reamers. Taper Tap: A type of hand tap that has 8 to 10 tapered threads and is often used to tap through holes. A taper tap is the first tap used in a tapping sequence when tapping blind holes. Through Hole: A hole that begins on one side of a work piece and extends through and exits another surface of the work piece.
