Cleveland C09733 Extra Length Drill Bit 0.5312 in Hss

Product Description

The CLEVELAND C09733 is an extra length high-speed steel drill bit designed for deeper drilling and long-reach drilling applications where standard-length bits cannot reach. The bit measures 0.5312 inches in diameter with a 10-inch overall length and a 7.5-inch spiral flute. It features a 118-degree standard point angle with web thinning applied to reduce entry force and improve chip clearance. The oxide finish provides mild corrosion resistance during storage and initial use. With a straight-cylindrical shank and right-hand cutting direction, this bit fits standard drill chucks without adapters. It is suited for use by machinists, pipefitters, and HVAC or plumbing fabricators working in steel and cast iron.

The C09733 is intended for production and maintenance drilling in cast iron and steel — two of the most common materials encountered in mechanical, HVAC, and plumbing rough-in work. The extended overall length makes it practical for drilling through thick structural members, deep flanges, or assemblies where a jobber-length bit would bottom out in the chuck before reaching the workpiece. The regular spiral flute type promotes steady chip evacuation throughout the full flute length. This bit is sold individually and is part of the Cleveland Series 950E extra length line.

Key Features

• 0.5312 inch diameter with a tolerance of +0.0000 to -0.0012 inches for accurate hole sizing
• 10-inch overall length and 7.5-inch flute length for deep-reach drilling
• 118-degree standard point with web thinning and tapered web configuration for easier penetration
• High-speed steel construction for durability in steel and cast iron applications
• Oxide finish for basic corrosion protection
• Straight-cylindrical shank — 17/32 inch diameter — fits standard drill chucks
• Right-hand cutting, 2-flute, regular spiral for consistent chip removal

Compatibility

Designed for drilling into cast iron and steel workpieces. Suitable for general-purpose deep-reach drilling applications per Series 950E specifications. Conforms to ASME B94.11M and ANSI standards.

Installation Notes

Secure the straight-cylindrical shank firmly in a properly sized drill chuck before use. Always wear eye protection and secure the workpiece before drilling. Reduce feed pressure at breakthrough to prevent grab or bit deflection on long-reach operations. Use appropriate cutting fluid for steel applications to extend bit life and maintain hole tolerance.
