Cleveland C09669 5/16 Inch Extra Length Drill Bit Hss

Product Description

The CLEVELAND C09669 is a high-speed steel extra length drill bit designed for deeper-reach and long-reach drilling applications. Built to the 950E series specification, it features a 5/16 inch diameter, a 118-degree standard point angle, and a web-thinned, tapered web construction that reduces entry resistance and improves chip clearance. The spiral flute geometry is a right-hand, regular spiral with two flutes, providing efficient material removal. An oxide finish adds surface hardness and helps resist heat buildup during cutting. This bit is sized for jobs where a standard-length drill cannot reach the work zone without interference.

The C09669 is suited for metalworking applications in maintenance, fabrication, and mechanical trade environments. Its primary workpiece materials are cast iron and steel, making it appropriate for structural, pipe fitting, and general mechanical work. The extra overall length is especially useful when drilling through deep stock, spacers, or assemblies where tool clearance is a limiting factor. Licensed trades including plumbers, HVAC installers, and electricians regularly use extra-length bits when routing holes through structural members or deep assemblies.

Key Features

• 5/16 inch diameter with a tolerance of +0.0000 to -0.0010 inches for precise, controlled hole sizing
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust and cleaner entry
• 8 inch overall length and 5.5 inch flute length for deep-reach and long-reach drilling
• High-speed steel construction with oxide finish for heat resistance and extended service life
• Two-flute regular spiral design with right-hand cutting direction for standard rotary drilling equipment
• Rated for cast iron and steel; general-purpose grade suitable for a wide range of metal fabrication tasks

Compatibility

Designed as an OEM-style general-purpose extra length drill bit compatible with standard 3-jaw drill chucks and rotary drilling equipment that accept straight-cylindrical shanks in 5/16 inch diameter.

Installation Notes

Installation is performed by qualified tradespeople using standard rotary drills or drill presses fitted with a compatible chuck. Ensure the workpiece is securely clamped before drilling to prevent movement and bit breakage. Apply cutting fluid or coolant when drilling steel or cast iron at sustained depths to manage heat. Meets ASME B94.11M and ANSI specifications; users in California should note this product is subject to California Proposition 65 requirements.
