A Brief Understanding of Tap and Die Set
Screw threads are produced via a process called threading; various methods of doing such are available; however, the most widely and acceptable method is that done with a Tap and Die set.
Essentially a tap and set die is a two in one tool that allows for the creation of threads both around a hole and into a thread; a tap does the former by cutting the metal from inside and the die set does the latter by carving metals from outside.
A Tap is a tool you use to cut threads into a hole so that a bolt can be screwed into it and a die for making threads for nuts (outside the metal).
Types of Taps
It is a prerequisite to know that taps come in different forms and sizes and each with its attendant benefits and challenges too. Generally, you can divide tap into 2 types; manual, and power taps.
The first-class are the manual taps. By design, they are intended to be manually operated and they include the following;
This one has a constant cutting edge and basically zero taper. The number of threads is usually one to one point five per taper.
Uses – This one is employed for cutting threads for the lower part of a blind hole; its name gives away its function.
Unlike the bottoming tap, This one features tapered cutting edges. The number of threads ranges from three to five.
Uses - The principal use of this to make alignments.
It possesses a more pronounced taper to the cutting edges. The number of threads ranges from eight to ten.
Uses: It’s used on delicate materials or those with a small diameter.
The second class of Taps includes;
Materials Needed for Tapping and Die Setting
How to use a Tap and Die Set
Drilling the Hole to the Correct Diameter and Depth
For each tap, there is a corresponding drill size to drill the hole. The exact hole diameter is determined by checking the drill and tap size chart; a standard reference item found in many machine shops and the net.
You can also use a screw piece gauge to match one of the blades to the thread profile.
Secure the Piece to be Tapped
Do this by using a vice, because taps are very brittle and too much movement doubles the risk of breakage.
Tapping the New thread
To do this, you have to follow the following steps.
Apply Cutting Oil
Next, at this point, your die comes in handy. Apply your cutting oil into the threaded material.
Your die is simply an inverse of the tap; it cuts threads on the outside of the rod.
You Should Always Apply Lubrication Oil
The process of tapping and die setting requires lubrication to ensure an efficient and fast threading process. These following lubricants are suggested for you; the lubricant to be used depends on the material in question.
Precautionary Measures to Adhere to When Tapping and Die Setting
Tapping and die setting at first can be scary, but such fears can be countered by following this tutorial line by line to the later and also by understanding that mastery comes with some degree of patience and practice.
