Cleveland C03753 3/16 Inch Hss Tin Jobber Drill Bit

Product Description

The CLEVELAND C03753 is a 3/16 inch high speed steel (HSS) jobber drill bit with a titanium nitride (TiN) coating, designed for general purpose drilling in steel and cast iron. It features a 118-degree notched point with web thinning for improved penetration and reduced thrust. The parabolic flute geometry promotes faster chip evacuation and supports deeper cuts without packing. With an overall length of 3.5 inches and a straight cylindrical shank, this bit fits standard drill chucks and is built to ASME B94.11M standards. It is suited for use by machinists, pipefitters, HVAC technicians, and other trade professionals requiring consistent hole quality in ferrous materials.

The C03753 is used in production and maintenance drilling applications where a reliable, coated HSS bit is needed for ferrous workpieces. Typical scenarios include drilling sheet metal, structural steel, cast iron housings, and mechanical components encountered in HVAC, plumbing, and electrical trade work. The TiN coating extends tool life compared to uncoated HSS by reducing friction and heat buildup at the cutting edge. This bit is sold individually and is part of the Cleveland Series 2065TN line.

Key Features

• 118-degree notched point with web thinning reduces entry force on steel and cast iron
• Parabolic flute design improves chip flow and allows maximum drilling depth of 2.9375 inches
• Titanium nitride (TiN) coating increases surface hardness and extends bit life over uncoated HSS
• Straight cylindrical shank at 0.2656 inches diameter fits standard 3-jaw drill chucks
• Right-hand cutting direction; two flutes; tapered web configuration for rigidity

Compatibility

Designed as a general purpose jobber drill bit for use in hand drills, drill presses, and CNC equipment with standard straight-shank chuck systems. Primary workpiece materials are steel and cast iron per Series 2065TN specifications.

Installation Notes

This bit is installed and operated by machinists, pipefitters, electricians, and HVAC technicians using standard drill chucks. Secure the shank fully in the chuck before operation and confirm the workpiece is clamped or fixtured to prevent rotation. Use appropriate cutting fluid or coolant when drilling ferrous materials to preserve edge life, noting this bit does not support through-coolant delivery. Inspect the cutting edges before each use and replace if chipping or excessive wear is observed.
