Cle-Line C20750 118 Degree Silver & Deming Drill
This reduced-shank drill bit is made from high-speed steel with a black oxide finish for general-purpose machining. The 118-degree point angle provides standard cutting performance across common materials. It suits maintenance technicians and fabricators who need a single large-diameter hole in a single pass.
1/2 Reduced Shank and Black Oxide Finish
The 1/2 reduced shank allows the 25/32 in bit to fit standard drill chucks without a specialty holder. Black oxide coating adds lubricity and helps resist corrosion during repetitive drilling cycles. These features reduce tool-change time and extend usable life in workshop environments.
25/32 Inch Diameter Capacity and Headroom
The bit cleanly produces 25/32 in holes in mild steel, cast iron and non-ferrous alloys where a standard chuck is the only drive available. It is not suited for deep-hole drilling beyond the flute length or for hardened steels that require cobalt or carbide tooling. Users needing smaller step sizes or larger diameters will require additional bits.

Questions about this item
Will the 118 degree point need regrinding on high speed steel?
The 118 degree point on high speed steel can be resharpened when it dulls, extending the bit life without replacing the tool.
What limits continuous drilling with the 25/32 inch diameter?
The large 25/32 inch diameter demands high torque and slow feed rates, so machine power and chip evacuation become the practical limits.
How much heat builds up in the black oxide finish during all-day use?
Black oxide helps retain lubricant and reduce friction, but sustained heavy drilling still generates significant heat at the cutting edges.
