Drill bit size and material

The Cleveland 9670 is a fractional-inch jobber drill bit made from high-speed steel with a black-oxide finish. It measures 21/64 in diameter and is designed for general-purpose machining tasks. The bit suits workshops and technicians who need a durable cutting tool for everyday metal drilling.

118-degree conventional point

The bit features a 118-degree conventional point angle with a 28-degree helix. This geometry provides reliable centring and chip evacuation in a wide range of ferrous and non-ferrous materials. It is the single specification that determines whether the bit matches the material and hole-quality requirements of the job.

Maximum depth and shank fit

The flute length allows a maximum drilling depth of 5 1/2 in, so the workpiece and fixture must accommodate that reach. The straight shank fits standard three-jaw chucks and quick-change holders, freeing the user from specialised collets or adapters. Ensure the machine spindle runs true to avoid premature wear.

Questions about this item

What does the 118-degree point angle mean for everyday drilling?

The 118-degree point is a conventional general-purpose angle that centres easily in steel, wood and plastic without a pilot hole, giving reliable starts on a wide range of materials.

How does the 28-degree helix affect chip removal?

A 28-degree helix is a standard flute angle that lifts chips steadily from holes up to five-and-a-half inches deep, reducing clogging in deeper cuts.

What shank size does the 21/64-inch bit need in a chuck?

The bit has a straight shank matching its 21/64-inch diameter, so it fits any three-jaw chuck that opens to at least that size.
