Cle-line C18044 Jobber Drill Bit Letter Q Hss Gold Oxide

Product Description

The CLE-LINE C18044 is a jobber length drill bit sized at Letter Q (0.3320 inches decimal), designed for high-performance drilling in ferrous materials. Built from high speed steel with a gold oxide coating, it features a 135-degree split point for self-centering starts and reduced walking on hard surfaces. The tapered web and web-thinned geometry lower feed pressure and improve chip evacuation through the two spiral flutes. At 4.75 inches overall length with a 3.4375-inch flute length, it fits standard drill chucks and drill presses used daily in metalworking and fabrication shops. This is a heavy-duty, right-hand cut bit conforming to ASME B94.11M and DIN 338.

The C18044 is suited for drilling cast iron and steel in production and maintenance environments. Its straight cylindrical shank and regular spiral flute type make it compatible with both handheld drill drivers and benchtop drill presses. The gold oxide finish provides mild lubricity and corrosion resistance during storage and use. Machinists, millwrights, pipefitters, and general fabricators will find this bit appropriate for through-hole and clearance-hole drilling in structural and machine steel applications.

Installation Notes

Install this bit into a properly sized drill chuck and tighten securely before operation. Always power down or disconnect the drill before changing bits. Use cutting fluid or coolant when drilling steel at higher feed rates to extend tool life - note this bit does not support coolant-through delivery. Inspect the split point for wear or chipping before each use; a dull or damaged point should not be forced through the workpiece.
