FAQ's: Taper Shank Drill Bits

Keep the shank and socket clean, store bits in protective holders, and resharpen as needed to maintain cutting performance.

Yes, when drilling metal. Lubrication reduces friction, heat, and wear.

Check your machine’s spindle specifications — using the wrong size will cause poor fit and unsafe operation.

Yes — choose the right material and point style for the material being drilled.

For large diameters, yes — starting with a smaller drill improves accuracy and reduces load on the bit.

Usually high-speed steel (HSS) for general-purpose drilling, with cobalt or carbide options for harder materials.

They range from small diameters to over 3 inches, with shanks matching common Morse taper sizes.

No — they’re designed for stationary machines with matching tapered sockets.

When properly seated and clean, they rarely slip. If slippage occurs, clean both the bit shank and the spindle socket.

Use a drift key (wedge-shaped tool) inserted into the spindle’s slot to knock the bit free.
