The tool for cutting internal threads is called a tap. A tool for cutting external threads is called a die.

Honing is a sort of hole finishing operation performed after drilling. The honing tool is a multipoint cutting tool. There will thin projections parallel to the length of tool extending from one cross section to other. When the tool is inserted into the hole, a loading is given on the cross section of the tool which extends a spring attached to the projections pushing the "abrasive cutting edge" out side and then it is rotated so as to give finishing. This method is generally use in the cylinder of IC engines.. Rough sketch:- ------------------------------ ================= ================= ----------------------------- Dotted arrows show the 2 peripheries of the cutting tool and "equal to sign" shows edges of abrasives. The pushing of spring radially connected to the centre pushes the cutting edge of abrasives out which enables finishing operation
As a general rule, a bolt should engage a distancegreater than or equal to its outer diameter. The number of threads engaged can then be calculated from the number of threads per inch on the bolt. So if you are using a 1/4-20 bolt, meaning it has 1/4" diameter and 20 threads per inch, you should engage the bolt 1/4" into the hole, or 5 threads. (20 threads/inch x 1/4 inches)Why: The shear stress on the threads will be equal to the tensile stress in the shank of the bolt. This means that once you thread the bolt in a distance greater than its diameter, the shank itself will fail before the threads shear off the bolt under tensile load.Sources: Design of Machinery class at Purdue University, page 10 of the following MIT article: http://web.mit.edu/2.75/resources/FUNdaMENTALs%20Book%20pdf/FUNdaMENTALs%20Topic%206.PDF
# Cutting and shaping methods are , Saws (hand or electrical) , guillotines, tin snips , drill and hole saws, Punch/cropping machines , abrasive disks / paper and files. (PE02 - 005 ) HOPE THIS HELPS
-The drill press can take bits of up to 1/2 shank size and many of those are drill bits up to an inch wide. ( it's quite common to have large drills with reduced shanks) -Other items like large hole saws can be used, as well as 'fly cutters', which are cutting bits on the end of a movable beam. These can usually cut holes in thin materials like plexiglass sheet, up to a foot in diameter. Forstner bits up to 6 or 8 inch can be used, these cut large, flat bottomed holes for installing clocks and other instruments. Milling bits can be used to 'mill' large areas of rough surface to smoothness, and 'square hole tools' can also be used. The large drill press is a very versatile tool.
A jigsaw is the best tool to use for cutting a square hole in wood.

Internal threads are threads inside of a hole in something. Like a nut, for instance. External threads are threads on the outside of a cylindrical object. Like a bolt, for instance. hth, Steve
is when you re-cut the threads in a bore using a die tool that is struck and then turned to make the threads
Assuming you mean "thread tap", it is for cutting new threads in a hole.
The hole that you put a screw into is referred to as a "tapped hole". The rib-like things in the hole are called "threads" or, more specifically, "internal threads" as opposed to the external threads on a screw.
The difference between internal flush and full hole thread is that the roots of the full-hole tool joints are rounded, and the roots for the internal-flush joints are flat.
To sharpen a leather hole punch tool effectively, use a fine grit sharpening stone or sandpaper to gently sharpen the cutting edge of the tool. Be sure to maintain a consistent angle while sharpening and periodically test the tool on a scrap piece of leather to ensure it is cutting cleanly.
A tap is a tool, a tap can cut or clean the threads of a bolt hole, there are differant diameters and thread pitch, a dye is the opposite of a tap it cuts or cleans the threads of a bolt.
To effectively cut a square hole in a material, you can use a square-shaped cutting tool, such as a square drill bit or a square punch. Make sure to mark the area where you want the hole to be with a pencil or marker, then carefully cut along the lines using the cutting tool. It is important to use proper safety equipment, such as gloves and goggles, when cutting materials.
A jigsaw with a metal cutting blade would be a good tool to use for cutting a hole in a door with aluminum in the middle. Make sure to use a slow and steady cutting motion to prevent damage to the door surface. Additionally, consider using a metal file to smooth out any rough edges after cutting.
