Application & Fit

The Cleveland 12220 is a taper shank drill bit sized at 47/64 inch with a decimal equivalent of .7344. It is made from high speed steel with a steam oxide finish and a 118 degree point angle. This fractional inch bit suits maintenance and metalworking tasks where a Morse taper holder is used.

Shank Interface Limits

The taper shank locks into a matching Morse taper socket or sleeve, so the machine must accept that specific taper size. Drive torque transmits through the friction fit, which can loosen under heavy feed pressure or vibration. The bit cannot be used in a three-jaw chuck without a separate adapter, and the shank diameter is fixed by the taper standard.

Decisive Specification

The 47/64 inch cutting diameter is the single figure that determines whether this bit matches the hole required. Buyers who need a different fractional size, a metric diameter, or a reduced shank for a standard chuck cannot use this part. The 118 degree point angle is general purpose, not specialised for hard materials or high-speed production drilling.

Questions about this item

Should I pick the 47/64 inch size or a different fractional size?

Choose 47/64 inch when the hole must be exactly .7344 decimal inches; other fractional sizes in the same series step up or down in 1/64 increments.

What does the 118 degree point angle do once the bit is in the drill press?

The 118 degree point centres quickly in steel and cast iron and clears chips through standard flutes without needing a split-point design.

How does the Morse taper shank limit what machines I can use it with?

The Morse taper seats directly in a matching taper socket or sleeve; it will not fit a straight-shank chuck without an adapter.
