Cleveland C12229 Taper Shank Drill Bit 13/16

This Cleveland C12229 is a high-speed steel drill bit with a Morse taper shank for secure mounting in machine spindles. It is built for machinists and maintenance technicians who need accurate holes in ferrous and non-ferrous metals. The steam oxide finish helps retain cutting fluid and reduces wear during repetitive drilling cycles.

Taper shank versus straight shank

A taper shank bit replaces a straight shank drill when the machine spindle accepts a Morse taper directly, eliminating the need for a separate drill chuck. The upgrade is worth it when you require maximum concentricity and torque transfer for deep or large-diameter holes in a production environment. Straight shank drills remain the choice for portable drills or when a chuck is mandatory.

Capacity and headroom

The 13/16 inch fractional size cuts a precise 0.8125 inch diameter hole with a standard 118 degree point angle suited for general-purpose metal drilling. High-speed steel provides reliable tool life in mild steel, cast iron and aluminium alloys. The bit reaches its limit in hardened steels or high-temperature alloys where cobalt or carbide tooling becomes necessary for acceptable wear rates.

Questions about this item

What Morse taper size does the 13/16-inch Cleveland C12229 bit need in the spindle?

The bit uses a standard Morse taper shank that matches the 13/16-inch diameter; most machines accept a No. 3 Morse taper for this size.

How do I seat the taper shank correctly so the bit runs true?

Clean both the spindle socket and the shank, insert the bit, then give it a firm twist by hand to lock the taper before tightening the drawbar.

When should I replace or re-sharpen the 118-degree point on this high-speed steel bit?

Re-sharpen when the cutting lips show visible wear or the bit starts to walk; the steam-oxide finish helps chip flow but does not prevent dulling.
