Cle-Line C23811 Double-End Drill Bit
The Cle-Line C23811 is a high-speed steel drill bit with a 135-degree split point designed for precision drilling in metal. It targets machinists and technicians who need a durable bit for repetitive hole-making tasks.
Sustained Load Performance with Steam Oxide Finish
The steam oxide surface treatment helps retain lubricant and reduces friction during extended drilling cycles. High-speed steel construction maintains hardness at elevated temperatures, allowing the bit to resist wear when used continuously in ferrous materials.
Installation and Common Issues
The 3.26 mm shank diameter fits standard drill chucks and quick-change adapters without modification. Split-point geometry minimises walking at the start of the cut, though excessive feed pressure can still cause premature tip wear or breakage in harder alloys.

Questions about this item
How hot does the 135-degree split-point HSS bit get during extended drilling?
High-speed steel with a 135-degree split point dissipates heat efficiently during continuous use; the steam oxide finish reduces friction and helps keep temperatures manageable in wire-gauge drilling.
What chuck size is needed for the 3.26 mm shank?
A standard 1/4-inch or 3 mm drill chuck will grip the 3.26 mm shank securely; no special collet or adapter is required for common corded or cordless drills.
Will the #30 wire-size bit work in older 1/4-inch chuck drills?
Yes, the 3.26 mm shank fits legacy 1/4-inch chucks without modification, and the 1/2-inch flute length is compatible with standard drill depths on older machines.
