Cleveland C12204 Taper Shank Drill Bit 5/8" 118° High Speed Steel Steam Oxide

Cleveland C12204 Drill Bit

The Cleveland C12204 is a taper shank drill bit sized at .6250 inch. It is made from high speed steel with a steam oxide finish and a 118 degree point angle. This tool suits machinists and maintenance technicians who need a reliable general-purpose bit for drilling ferrous and non-ferrous metals. It fits directly into taper-shank holders or spindles without a separate chuck.

Taper Shank and Steam Oxide Finish

The Morse taper shank seats securely in compatible drill presses or tailstocks, reducing runout during heavy feeds. High speed steel construction resists wear when cutting steel, cast iron and similar materials. The steam oxide surface treatment helps retain cutting fluid and reduces chip welding, extending usable life in repetitive drilling operations. No coolant channels or special coatings are present.

Thermals and Power Draw

Heat generation depends on the workpiece material, cutting speed and feed rate applied by the operator. High speed steel tolerates the temperatures typical of conventional drilling when proper lubrication is used. The bit draws no power itself; load is determined by the driving machine and the depth of cut. Excessive pressure or insufficient coolant will raise tip temperature and accelerate edge wear.
