The PRECISION TWIST DRILL 1012460 is a 1700M series plug tap designed for hand tapping operations across a wide range of materials. A plug tap features a chamfer of approximately 3 to 5 threads, making it the most common tap style for starting threads in both through holes and blind holes. It is selected by machinists, pipefitters, and maintenance tradespeople when a reliable, general-purpose tap is needed for threading tasks in metal fabrication, HVAC equipment assembly, plumbing fixture work, and general industrial maintenance.
This plug tap is suited for both through hole and blind hole applications, giving the installer flexibility across typical service and fabrication scenarios. The 1700M series designation indicates a metric-compatible design intended for use in production and maintenance environments where consistent thread quality is required. It is appropriate for bench work and field service where a hand tap wrench or tap handle is used to drive the tap manually.
Designed as a general-purpose hand tap compatible with standard tap handles and wrenches used in threading operations across a wide variety of base materials including metals commonly encountered in HVAC, plumbing, and industrial maintenance applications.
Installation should be performed by a qualified machinist or tradesperson familiar with manual tapping procedures. Always secure the workpiece firmly before beginning and use appropriate cutting fluid to reduce friction and extend tap life. Back off the tap periodically to break chips and prevent binding, particularly in blind hole applications. Follow applicable shop safety practices and relevant trade codes when performing threading operations on pressurized or structural components.
