Cleveland C11669 Jobber Drill Bit 15 Hss 135 Degree

Product Description

The CLEVELAND C11669 is a wire gauge size 15 jobber length drill bit designed for precision drilling in metal fabrication, maintenance, and production environments. Built from high speed steel with a bright uncoated finish, it features a 135-degree split point that reduces walking and allows for faster penetration without a center punch. The overall length is 3.375 inches with a flute length of 2.1875 inches and a straight-cylindrical shank diameter of 0.1800 inches. The 2-flute spiral configuration promotes efficient chip evacuation. This bit is suited for HVAC techs, plumbers, electricians, and general trade professionals who need reliable performance in tight quarters or production drilling.

The C11669 is rated for use on aluminum as its primary workpiece material and is built to heavy duty grade specifications under NAS 907 Type B standards. It fits standard drill chucks and is appropriate for portable drills, drill presses, and production machinery commonly found in sheet metal shops, electrical panel fabrication, and mechanical service work. The regular spiral and tapered web with web thinning make it particularly efficient when drilling non-ferrous metals and soft alloys at consistent feed rates.

Key Features

• Wire gauge size 15 with 0.1800 inch decimal diameter for precise hole sizing
• 135-degree split point reduces drill walking and lowers required thrust force
• High speed steel construction with bright uncoated finish for general-purpose durability
• 2-flute regular spiral with tapered, web-thinned design for efficient chip removal
• Straight-cylindrical shank fits standard 3-jaw drill chucks without adapters
• Meets NAS 907 Type B specification for heavy duty drilling applications

Compatibility

Designed as a jobber length replacement or standard stock drill bit for any application requiring a 0.1800 inch diameter hole, compatible with standard drill chucks accepting straight-cylindrical shanks of the same diameter. Primary workpiece material rating is aluminum per manufacturer specification.

Installation Notes

Installation of this drill bit should be performed by a qualified technician familiar with rotary cutting tools and applicable shop safety practices. Secure the shank fully in the chuck and verify runout before drilling. Power down the drill completely before changing bits. Do not exceed the recommended feed rate or RPM for the workpiece material, and ensure proper clamping of the workpiece to prevent movement during operation.
