Cleveland C11623 Jobber Drill Bit 13/32 in Hss 135 Deg

Product Description

The CLEVELAND C11623 is a jobber-length twist drill bit designed for precision hole-making in metalworking and fabrication applications. Built from high-speed steel (HSS) with a bright uncoated finish, this bit features a 135-degree split point that reduces walking and allows for faster penetration without a center punch. The 13/32 inch diameter (0.4062 inches decimal) paired with a regular spiral and web-thinned geometry helps reduce thrust force during drilling. With an overall length of 5.25 inches and a flute length of 3.875 inches, this is a standard jobber-length tool suited for use in drill presses, hand drills, and production setups. Licensed HVAC techs, sheet metal workers, plumbers, and electricians regularly keep jobber-length bits on hand for rough-in and fixture work.

The C11623 is rated as heavy duty and meets NAS 907 Type B standards, making it appropriate for demanding production and maintenance environments. Its primary workpiece material designation is aluminum, though HSS bits of this geometry are routinely used across a range of non-ferrous and ferrous materials. The straight-cylindrical shank fits standard 3-jaw drill chucks without adapters, and the two-flute spiral design clears chips efficiently during through-hole operations. This bit is well suited to both shop use and field service work where consistent hole sizing is required.

Key Features

• 135-degree split point reduces bit walking and lowers required thrust force
• Web-thinned, tapered web design improves chip evacuation and cutting efficiency
• High-speed steel construction handles repeated use across non-ferrous and ferrous materials
• Bright uncoated finish allows easy visual inspection of cutting edge wear
• Straight-cylindrical shank fits standard drill chucks without adapters
• Meets NAS 907 Type B specification for heavy-duty drilling applications

Compatibility

Designed as a direct-fit jobber-length drill bit for any standard drill chuck accepting a 0.4062-inch straight-cylindrical shank. Compatible with bench-top drill presses, magnetic drills, and hand-held power drills used in HVAC, plumbing, electrical, and general metal fabrication work.

Installation Notes

Always secure the workpiece before drilling and verify chuck tightness before starting the spindle. Use appropriate cutting fluid or lubricant when drilling ferrous materials to extend cutting edge life. Wear eye protection and ensure the drill press or tool is de-energized before changing or inspecting bits. Dispose of worn bits per shop safety protocols — dull HSS bits can deflect and cause inaccurate hole sizing.
