Taps

Taps are designed with cutting teeth and either helical or straight flutes for the passage of chips and the admission of cutting fluid. The purpose of cutting internal threads is so that they can receive a part with an external thread, such as a bolt, rod, or fastener. These two parts can then be joined together. Taps can be made out of different types of steel and can be engineered for different applications.

Taps are Rotary Cutting Tools that Cut Internal Threads in Metal

Anatomy & Nomenclature

The SHANK fits into the tap holder. The SQUARE at the end of the tap drives and rotates the tap. FLATS are the sides of the square at the end of the shank.
The FLUTES are grooves that provide a path for the removal of chips and the flow of cutting fluid.
The POINT controls the ejection of chips*
*Spiral Point Taps AKA "Gun Taps" are ideal for through-hole applications.
The NECK enables the flow of lubricant and deeper tapping.
The CHAMFER aligns the tap and provides easy starting.

How to Tap The Right Size Hole

A screw or fastener will only fit properly into a threaded hole if:

The hole was drilled to the proper diameter and
The hole was properly tapped

Consult your tap/drill chart to determine the correct diameter drill.

Drill Diameter Options for ¼-20 Thread (see highlight on the chart) ¼-20

Tap Drill Size 9 | 7 | 13/64”
Prob % of Thread 77 | 70 |66

#7 drill will yield a 70% of thread
#9 drill (smaller) will yield a smaller hole-tap will work harder. You will achieve a higher % of thread (77%) but tap life will be shortened
13/64” drill (larger) will result in less thread engagement (66%)
