What drill bit size for .125 in. national pipe thread?
Use 7/64 as tap drill and 9/64 as clearance drill
What size drill for 12 metal screw?
If you want it to grip, drill a 9/64 hole. For a clearance hole, drill 7/32.
What drill bit size for a 832 screw?
That size is 8-32. The drill bit for a clearance hole is 11/64, or a #17 drill bit.

What is Name the parts of a twist drill?
The parts of a twist drill include the shank, neck, flutes, land, body clearance, and cutting edge. The cutting edge is the point of the drill bit and does the actual cutting.
Which angle is not to be changed while drill grinding?
The clearance angle, also known as the relief angle, should not be changed while drill grinding. This angle is crucial for allowing the cutting edges to clear the workpiece effectively and prevent binding. Maintaining the correct clearance angle ensures efficient cutting and enhances the lifespan of the drill bit. Adjusting other angles, such as the point angle or lip angle, can be beneficial for specific applications, but the clearance angle must remain constant.
What size is a m20 drill bit?
A 20mm or 13/16 drill bit will allow the bolt to fit through.
What is a clearance drill used for?
A clearance drill is used in various contexts, primarily in military and emergency response training, to ensure that a specific area is secured and free of threats or hazards. It involves systematically searching and clearing an area to eliminate potential dangers, such as hidden weapons or explosive devices.

What is Shank-clearance hole?
A shank-clearance hole is a specific type of hole machined into a component to allow for the movement or clearance of the shank of a tool, such as a drill bit or a milling cutter. This hole ensures that the tool can operate without interference from the surrounding material, facilitating better access and movement during machining operations. It is particularly important in applications where tools have a shank that extends into a confined space.
How drill bit equivalence is calculated?
Most technicians have a steel ruler with metric on one edge and SAE on the other edge, so it's easy to calculate. Many technicians of all kinds also carry diaries or small log books with tables of this and much more technical information. One of the charts in my diary has drill sizes in decimal, SAE and metric, also tapping drill and clearance drill sizes for bolt and screw threads.
