What is anti-boring?

Counterbore (symbol: ⌴) is A cylindrical flat-bottom hole that expands another coaxial hole, or the tool used to create the feature. … countersinks are flat-bottomed enlargements of smaller coaxial holes, while countersinks are tapered enlargements of such holes.

What is backboring on a lathe?

Backboring: Backboring is The operation of expanding one end of a square bottom hole concentric with the original hole. This is done to accommodate the heads of bolts, studs and pins. Counterbore (tools used for counterbore) cutting edges can have straight or helical teeth.

What is the purpose of a countersink?

Countersinking creates a tapered hole that matches the angle of the screw so that when the screw is fully engaged, the head will be flush or slightly below the surface.Countersunk is For widening the opening of the hole to create a flat bottom Therefore, the socket head cap screws will be flush with the surface of the part.

What is the difference between countersinking and countersinking?

The difference between spot facing and spot facing is that Counterbore surface usually has a shoulder at the bottom of the enlarged holewhile the spot facing is flat and always at right angles to the axis of the hole.
