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. This drill enhances preparedness, coordination, and safety for personnel involved in operations or rescue missions. Additionally, it can be applied in non-military settings, such as ensuring the safety of a building before an event.
Use 7/64 as tap drill and 9/64 as clearance drill
If you want it to grip, drill a 9/64 hole. For a clearance hole, drill 7/32.
That size is 8-32. The drill bit for a clearance hole is 11/64, or a #17 drill bit.
For a clearance hole you need a 9/64 drill bit.
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.

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.
A Q clearance is a security clearance for the Department of Energy. Q clearance is specific to atomic and or nuclear material and is allowed to be used by non-military persons.
