Cleveland C09657 Extra Length Drill Bit 1/8 in Hss

Product Description

The CLEVELAND C09657 is a 1/8-inch diameter extra length drill bit engineered for deeper drilling and long-reach drilling applications where standard-length bits cannot reach. Built from high-speed steel with an oxide finish, it features a 118-degree standard point angle and a web-thinned, tapered-web construction that reduces thrust and improves chip evacuation. The spiral flute design with a right-hand cutting direction keeps the bit tracking true in cast iron and steel. At 8 inches overall length with a 5.5-inch flute length, this bit is suited for applications that demand extended reach without sacrificing rigidity.

This bit is intended for professional machinists, maintenance technicians, pipefitters, and fabricators working in metalworking environments where standard-length tooling falls short. Typical applications include drilling through deep stock, tube walls, structural steel, and cast iron components in production or field service settings. The straight cylindrical shank accepts standard drill chucks across a wide range of drill presses, hand drills, and magnetic base drills.

Key Features

• Extra length design at 8 inches OAL for deep-hole and long-reach drilling
• High-speed steel construction with oxide finish for wear resistance in ferrous materials
• 118-degree standard point angle with web-thinned, tapered-web geometry for reduced entry thrust
• Two-flute spiral configuration with right-hand cutting direction
• 1/8-inch straight cylindrical shank fits standard drill chucks
• Diameter tolerance held to +0.0000 to -0.0005 inches for precision fitment

Compatibility

Designed for use in cast iron and steel as primary workpiece materials, with cast iron listed as a secondary workpiece material. Conforms to ASME B94.11M and ANSI specifications. Series 950E general-purpose grade.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with metalworking practices. Secure the shank fully in the drill chuck and verify runout before drilling. Reduce spindle speed and apply cutting fluid when drilling deep holes in ferrous materials to manage heat buildup and chip clearance. Comply with applicable shop safety standards and OSHA requirements for rotating tool operation.
