Liming · A drill is a tool primarily used for making round holes or driving fasteners. It is fitted with a bit, either a drill or driver, depending on application, secured by a chuck.Some powered drills also include a hammer function.. Drills vary widely in speed, power, and size. They are characteristically corded electrically driven devices, with hand operated types dramatically decreasing in

Moreover, please be careful not to grind too much or too little. Table 2 Tool diameter D V （mm） 3 0.05～0.11 3over 8less 0.07～0.03
Determine the spindle speed (RPM) and feed rate (IPM) for a drilling operation, as well as the cut time for a given cut length. Drilling operations are those in which a cutting tool with sharp teeth, such as a twist drill, rotates and feeds into the workpiece axially, forming a hole with a diameter equal to that of the tool.

A good tap drill is 90% (± 2 pp) of major diameter for fine threads. For metric V threads, the concept of major minus pitch (i.e., the major or widest diameter of the intended screw in millimeters minus the pitch of the threads of that screw in millimeters per thread) yields a good tap drill diameter.
Pitch diameter: the Maximum and minimum sizes where the 1/2 Pitch intersects within the "V" shape of the screw thread. (this is the most important dimension of a thread) Minor diameter: The maximum and minimum sizes of the smallest diameter of the screw threads

Liming · Drilling is a cutting process that uses a drill bit to cut a hole of circular cross-section in solid materials. The drill bit is usually a rotary cutting tool, often multi-point.The bit is pressed against the work-piece and rotated at rates from hundreds to thousands of revolutions per minute.This forces the cutting edge against the work-piece, cutting off chips (swarf) from the hole as it is
