Cleveland C09674 Extra Length Drill Bit 25/64 in Hss

Product Description

The CLEVELAND C09674 is an extra length high-speed steel drill bit designed for deeper drilling and long-reach drilling applications where standard-length bits cannot reach. Built from high-speed steel with an oxide finish, it measures 0.3906 inches in diameter with an 8-inch overall length and a 5.5-inch spiral flute. The 118-degree standard point angle and web-thinned, tapered web design reduce entry force and improve chip evacuation. The straight-cylindrical shank measures 25/64 inch in diameter. This bit is suited for licensed machinists, maintenance mechanics, and industrial tradespeople working with cast iron and steel stock.

The C09674 belongs to Cleveland Series 950E and is intended for applications requiring deeper hole penetration or extended reach beyond the capacity of jobber-length bits. Typical use cases include through-drilling thick structural steel, cast iron components, and similar ferrous workpieces in manufacturing, maintenance, and fabrication environments. Its right-hand cutting direction and regular spiral flute geometry are compatible with standard drill presses, CNC machines, and hand-held drilling equipment used in trade and industrial settings.

Key Features

• Extra length design with 8-inch overall length for deep and long-reach drilling
• High-speed steel construction with oxide finish for wear resistance
• 118-degree standard point angle with web-thinned tapered web for reduced thrust and improved starts
• 5.5-inch spiral flute length promotes efficient chip clearing in deep holes
• Straight-cylindrical shank at 25/64 inch diameter fits standard drill chucks
• Rated for cast iron and steel primary workpiece materials
• Diameter tolerance held to +0.0000 to -0.0010 inches for consistent fit

Compatibility

Designed as a general-purpose extra length drill bit for use in cast iron and steel applications; compatible with standard drill chucks and machine spindles accepting a 25/64-inch straight-cylindrical shank. Conforms to ASME B94.11M and ANSI specifications.

Installation Notes

Installation and use should be performed by qualified machinists or tradespeople familiar with rotary cutting tools. Secure the shank fully in the drill chuck before operation and confirm the workpiece is properly clamped or fixtured. Wear appropriate eye and face protection when drilling ferrous materials. Follow applicable OSHA machine guarding and PPE requirements for the work environment.
