Product Information

Taper Tap The first tap in the set is called the taper tap. It has a more gradual cutting edge and is used to start the threading process. Its longer length helps guide the tap into the hole and gradually cut the threads.

Hand Taps - Hand taps are single taps designed for threading holes of varying depths. They are available a wide range of thread sizes and pitches. There are 3 main tap types: Taper Taps, Second Taps and Plug Taps. Each tap is used at different stages of the tapping process. Drilling and tapping centers, whose name sounds similar to that of tapping stations, are actually light-duty, affordable machining centers of 2, 2.5, or 3 axes that are designed for a life of mainly drilling and tapping with limited milling use.

Hand taps are cutting tools used in machining and metalworking to create internal threads, or threaded holes, in workpieces. These tools are manually operated and designed to be used without the use of a tapping machine. They come in various sizes and designs to accommodate different screw sizes and threading requirements. Here at Cromwell we have a large selection of hand taps from leading suppliers Sherwood, Dormer & Kennedy. If you’ve worked on a car repair at home or in any automotive, industrial or fabricator shop before you may know a tap is a common yet overlooked hand tool. Machining technologies have advanced and common taps have become more specific in use and in care. Learn about taps in their basic and complex forms and how they are used below. TAP GRADES – LAYMEN TERMS Hand taps are employed when there's a need to create threaded holes for screws, bolts, or other fasteners in a workpiece. They are generally used in situations where precision and manual control are crucial, such as in small-scale manufacturing, repairs, and projects where a power-driven tapping machine might not be suitable.

Tap & Drill Sets - A tap and drill set is an essential collection of tools designed to create threaded holes for bolts, screws, and other fasteners. These sets provide the necessary tools for tasks involving threading holes in materials like metal, plastic, or wood.where T D {\displaystyle TD} is the tap drill size, M D {\displaystyle MD} is the major diameter of the tap (e.g., ⅜ inch for a ⅜"-16 tap), and N {\displaystyle N} is the thread pitch (16 in the case of a ⅜"-16 tap). For a ⅜"-16 tap, the above formula would produce 5⁄ 16 as a result, which is the correct tap drill diameter for a ⅜"-16 tap. The above formula ultimately results in an approximate 75 percent thread. To help with this alignment task, several kinds of jigs and fixtures can be used to provide the correct geometry (i.e., accurate coaxiality with the hole) without having to use freehand skill to approximate it: Taps and Dies Terminology".

Length compensation: built in length compensation takes care of small push or pull to the spindle or feed difference. Both tools can be used to clean up a thread, which is called chasing. However, using an ordinary tap or die to clean threads generally removes some material, which results in looser, weaker threads. Because of this, machinists generally clean threads with special taps and dies—called chasers—made for that purpose. Chasers are made of softer materials and don't cut new threads. However they still fit tighter than actual fasteners, and are fluted like regular taps and dies so debris can escape. Car mechanics, for example, use chasers on spark plug threads, to remove corrosion and carbon build-up.Hand Tap Sets - They are designed to provide the necessary taps for different stages of the threading process, ensuring that you have the right tools to create accurate and clean threads. A typical tap set includes a Taper, Second and Plug. Double-lead taps and insert taps need different speeds and feeds, and different starting hole diameters than other taps. The third style is a bottoming tap. Bottoming taps have 1 to 2 tapered cutting edges before the full cutting force is engaged. Though this tap is extremely hard to start threads with, it is capable of cutting threads all of the way to the bottom of a blind hole. Bottoming taps are best used after a taper or plug tap has been used to cut the initial thread. While modern nuts and bolts are routinely made of metal, this was not the case in earlier ages, when woodworking tools were employed to fashion very large wooden bolts and nuts for use in winches, windmills, watermills, and flour mills of the Middle Ages; the ease of cutting and replacing wooden parts was balanced by the need to resist large amounts of torque, and bear up against ever heavier loads of weight. As the loads grew ever heavier, bigger and stronger bolts were needed to resist breakage. Some nuts and bolts were measured by the foot or yard. This development eventually led to a complete replacement of wood parts with metal parts of an identical measure. When a wooden part broke, it usually snapped, ripped, or tore. With the splinters having been sanded off, the remaining parts were reassembled, encased in a makeshift mold of clay, and molten metal poured into the mold, so that an identical replacement could be made on the spot.
