Cleveland C15123 Screw Machine Drill Bit #33
The Cleveland C15123 is a screw machine drill bit sized at #33 with a decimal equivalent of .1130. It is made from cobalt and coated with TiAlN for wear resistance. The 135 degree split point reduces walking and improves hole accuracy. This bit suits machinists and maintenance technicians drilling precise holes in metal.
Installation and common issues
The bit installs directly into a drill chuck or collet with a right-hand cutting direction. No coolant-through channels are present, so external lubrication is required for deep cuts. Overheating can dull the cobalt substrate quickly if feed rates are too aggressive. Proper clamping prevents breakage on the smaller diameter.
Who this suits and who should look elsewhere
This drill bit serves professionals needing a single #33 size for screw machine or CNC work in steel and alloys. Buyers who want a set of multiple sizes or a bit with internal coolant delivery will not find those features here. It is not intended for wood, plastic or masonry applications.

Questions about this item
How can I confirm the #33 bit is cutting correctly after I chuck it?
The 135° split point should self-centre and produce clean chips in steel without wandering.
What comes in the package and is anything else needed to use it?
The box contains the single C15123 cobalt TiAlN bit; a compatible drill chuck is required separately.
When should I choose the #33 size over another diameter?
Select #33 when the job calls for a 0.1130 in. hole; other sizes have different decimal equivalents.
