When you need to thread a hole it may seem easiest to reach for the nearest right size tap After all the threads will be identical in gage and will accommodate the type and size of external fastener threads But even before drilling the hole professional machinists consider the material being tapped whether the hole is through or blind and other variables before deciding

2021 03 17 nbsp 0183 32 The taper tap can be identified by the visible and pronounced tapering of the cutting edges This provides a very gradual and less aggressive cutting action The distinct feature of a taper tap is the 8 to 10 threads that taper from the tip to the full cutting force diameter A taper tap is most often used as a starter tap for difficult blind holes The gentle taper of the cutting

A tap cuts or forms a thread on the inside surface of a hole creating a surface that functions like a nut The three taps in the image illustrate the basic types commonly used by most machinists Bottoming tap or plug tap The tap illustrated in the top of the image has a continuous cutting edge with almost no taper between 1 and 1 5 threads of taper is typical

2006 08 25 nbsp 0183 32 Material Threadmills are generally more forgiving than taps in how it cuts In other words you could use the same threadmill to cut aluminum stainless plastics and alloys For a tap it may have other issues like changing coolant type adding Moly Dee blow out chips oversize the drilled hole tap the same hole twice etc

2020 04 08 nbsp 0183 32 The thread milling process can use helical interpolation tool paths to replace tapping and the thread mill looks similar to taps but the effect is different Insert the thread mill into the hole along axis of the spindle until deep enough to produce desired full thread depth the controller moves the thread mill to the position of hole diameter and cut threads into the hole

Threading chamfer type The tap chamfer is the tapering of the threads that distribute the cutting action over several teeth Usually the type of hole to be tapped decides which chamfer type should be used There are three common chamfer types B C and E Chamfer type B 3 5 – 5 x threads Long chamfer High torque Best surface quality Thin chips

2021 03 17 nbsp 0183 32 TYPES OF TAPS So what are the types of taps There are 3 main taps you should be familiar with and they are Taper Plug and Bottoming tap The taper tap can be identified by the visible and pronounced tapering of the cutting edges This provides a very gradual and less aggressive cutting action The distinct feature of a taper tap is the 8 to 10

SECOND TAPS have a lead of 3 5 threads at 8 degrees per side They are the most popular and can be used for through holes or blind holes where the thread does not need to go right to the bottom TAPER TAPS have a lead of 7 10 threads at 5 degrees per side The taper lead distributes the cutting force over a large
