Jobber drill bit 43/64

The Cleveland C08866 is a fractional-inch jobber drill bit made from high-speed steel with a black oxide finish. It is intended for general-purpose drilling in metal, wood and plastic where a standard 118-degree point angle is suitable. The bit suits trade users and DIYers who need a single replacement size rather than a full set.

Fits standard chucks and frees bit changes

The straight shank fits any three-jaw drill chuck that accepts a 43/64 inch diameter, so no special collets or adapters are required. Using a dedicated bit of this exact size avoids stepping up or down with undersized or oversized drills, which saves setup time and reduces the chance of hole oversize.

Capacity 0.6719" decimal equivalent

The 43/64 inch diameter equals a decimal size of .6719 inches, giving a precise reference for hole charts and tap-drill tables. The 118-degree point handles common materials but is not optimised for hard alloys or deep-hole drilling where a split-point or parabolic-flute design would perform better.

Questions about this item

At what drill bit size does the 43/64" diameter become the limiting factor for hole depth?

The 43/64" diameter and jobber length define the maximum hole depth in a single pass; deeper holes require a taper-length or extra-long bit.

How much heat does the black oxide HSS bit generate during all-day drilling in steel?

High-speed steel with black oxide finish dissipates heat effectively for continuous use, but cutting fluid is recommended to manage temperature during extended drilling.

What shank type must my drill chuck accept for this 43/64" bit to fit?

This bit has a straight round shank sized to its 43/64" diameter, so your chuck must accommodate at least 0.6719 inches.
