Cle-Line C23839 13/64 in Drill Bit
The Cle-Line C23839 is a 13/64 inch mechanics length drill bit designed for general machining tasks. It suits tradespeople and maintenance technicians who need a durable cutting tool for metalwork. The fractional inch measurement system matches standard workshop requirements. This bit handles everyday drilling jobs in steel and other common materials.
135 Degree Point Geometry and HSS Construction
The 135 degree split point reduces walking and starts holes cleanly without a centre punch. High speed steel construction resists heat buildup during extended drilling cycles. Black and gold surface finish adds lubricity and helps identify the tool quickly in a busy kit. These features combine to lower cutting force and extend edge life in normal use.
0.2031 Decimal Equivalent for Precision Fits
The 0.2031 inch decimal size allows exact matching to tap drill charts and reamer schedules. Mechanics length provides extra reach for confined workspaces without the fragility of longer jobber bits. The straight shank fits standard three-jaw chucks and quick-change adapters. No specialised holders or coolant systems are required for typical bench or portable drilling.

Questions about this item
How do I install the Cle-Line C23839 13/64 in drill bit in my drill chuck, and what step is often missed?
Open the chuck jaws wide enough for the 0.2031 in shank, insert the bit fully, then tighten securely; the step often missed is verifying the bit runs true before drilling.
What maintenance or replacement will this 135 degree high speed steel bit need later?
The cutting edges will dull with use; resharpen the 135 degree point angle to restore performance, or replace the bit when wear exceeds practical resharpening.
What limit appears first when using this mechanics length bit under sustained drilling?
Heat buildup at the 135 degree tip softens the high speed steel, causing rapid edge wear; reduce feed pressure and use cutting fluid to manage temperature.
