Cleveland C09735 Extra Length Drill Bit 9/16 in Hss

Product Description

The CLEVELAND C09735 is a 9/16-inch diameter extra length 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, this bit features a 118-degree standard point angle with web thinning for easier entry and reduced thrust. The spiral flute design — regular helix, 2 flutes — promotes chip evacuation in materials like cast iron and steel. At 10 inches overall length with a 7.5-inch flute length, it gives machinists and fabricators the reach needed for deep-hole work in production and maintenance environments. Installed and used by machinists, tool-and-die professionals, and industrial maintenance technicians.

The C09735 is suited for deeper and long-reach drilling in cast iron and steel workpieces. The Series 950E designation places it in Cleveland's extra-length line, built for applications where a jobber-length bit lacks the reach to complete the bore. A straight cylindrical shank seats directly in standard drill chucks, making it compatible with drill presses, milling machines, and hand-held power drills without adapters. This is a right-hand cutting bit intended for general-purpose production and maintenance drilling.

Key Features

• 9/16-inch diameter with a straight cylindrical shank of matching 9/16-inch diameter
• 10-inch overall length and 7.5-inch flute length for deep-hole and long-reach drilling
• 118-degree standard point with web thinning and tapered web configuration for reduced entry thrust
• High-speed steel construction with oxide finish for general-purpose durability
• 2-flute regular spiral design promotes chip clearance in cast iron and steel
• Right-hand cutting direction; meets ASME B94.11M and ANSI specifications

Compatibility

Designed for general-purpose drilling in cast iron and steel workpieces. Primary application is deeper drilling and long-reach drilling where standard-length bits are insufficient. Fits any drill chuck accepting a straight cylindrical 9/16-inch shank.

Installation Notes

Secure the shank fully in the drill chuck before operation and verify chuck key is removed before starting the spindle. Use cutting fluid appropriate for the workpiece material to extend bit life and improve surface finish in deep-hole operations. Reduce feed pressure as the bit approaches full flute depth to prevent chip packing and bit breakage. California Proposition 65 warnings apply to this product.
