Cleveland C09663 Extra Length Drill Bit 0.2188 in Hss

Product Description

The CLEVELAND C09663 is an extra-length, high-speed steel (HSS) twist drill bit engineered for deeper drilling and long-reach applications. Built to Series 950E specifications, it features a 118-degree standard point, a spiral flute with web-thinned, tapered web construction, and an oxide finish that helps reduce friction during cutting. The straight-cylindrical shank measures 7/32 inch in diameter with a 5.0-inch shank length, and the overall length comes in at 8 inches. This bit is a practical tool for machinists, maintenance technicians, pipefitters, and HVAC fabricators who need extended reach without sacrificing cutting performance.

The C09663 is suited for production and maintenance drilling into cast iron and steel workpieces where standard-length bits cannot reach. With a 5.5-inch flute length and right-hand cutting direction, it clears chips efficiently in deep-hole applications. Typical install scenarios include drilling through thick structural members, machine housings, deep flanges, or any setup requiring a longer bit to access a recessed bore. The 2-flute spiral design supports consistent chip evacuation in both ferrous metals and general-purpose materials.

Key Features

• Extra length at 8 inches OAL and 5.5-inch flute length for deep and long-reach drilling
• 118-degree standard point with web-thinned, tapered web for easier penetration and reduced walking
• High-speed steel construction with oxide finish for reduced friction and surface protection
• Right-hand, 2-flute spiral design promotes efficient chip clearing in deep holes
• Straight-cylindrical shank for standard chuck compatibility
• Diameter tolerance held to +0.0000 / -0.0007 inches for precision fitment

Compatibility

Designed as a general-purpose extra-length drill bit for use with standard straight-shank drill chucks; primary workpiece materials are cast iron and steel per manufacturer specification.

Installation Notes

Installation and use should be performed by a qualified machinist or tradesperson familiar with metal-cutting operations. Secure the workpiece firmly before drilling and confirm the bit is fully seated and tightened in the chuck before starting the spindle. Reduce feed pressure when the cutting tip first engages to prevent walking. Do not exceed the recommended RPM range for the workpiece material, and ensure adequate chip clearance on deep-hole passes to prevent bit binding or breakage.
