Round shanks have low torque transmissions, which can help prevent straight shanks from drilling very hard materials. Some drill bits feature straight shanks smaller in diameter than the bit itself, which allows for diversity in chuck size.

What are tapered shank drill bits used for?

Taper Shank Drills have a tanged conical shank to fit directly into the tapered holes of drill press spindles, driving sleeves or sockets. They are deigned for general purpose drilling in ferrous or non-ferrous metals.

What drill bit should I use?

Use a bit 1/64” smaller than the target hole size for softwoods. Use a bit exactly the same size as the hole when working on other materials. If you're not sure which to select, choose a drill bit 1/64” larger than the hole you wish to create. This will account for variables such a wood density and screw type.

What is the advantage of the taper shank?

Taper shanks are cone-shaped. One advantage of such an arrangement is that it centers the tool very accurately. For shanks of the size and with the degree of taper in the Morse series, friction alone is enough to turn the tool and to hold the shank in the socket.

What are straight flute drill bits used for?

When drilling a tough nonferrous material, such as titanium, you will need helical twist drill bits -- made of tungsten carbide.
