Cleveland C09760 1/2 in Taper Length Drill Bit Hss

Product Description

The CLEVELAND C09760 is a taper length drill bit designed for heavy-stock removal and deep-hole drilling applications where a standard-length bit falls short. Built from high-speed steel with a coated finish, this bit features a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The straight shank measures 1/2 inch in diameter and seats directly into standard drill chucks. Overall length is 12 inches with a 9-inch flute length, making it well-suited for applications that demand reach without sacrificing rigidity. General-purpose tool performance makes it a practical choice for production and maintenance work alike.

The C09760 is rated for use in alloy tool steel, carbon steel, and cast iron, covering the most common materials encountered in fabrication, maintenance, and repair environments. The right-hand spiral flute geometry pulls chips up and out of the hole during drilling, reducing heat buildup and improving hole finish. With a 3-inch straight shank and no coolant-through provision, this bit is intended for conventional drill press, hand drill, or mag drill setups where flood or through-coolant is not required. It conforms to ASME B94.11M standards, confirming dimensional consistency across the Series 950E product line.

Key Features

• 1/2 inch diameter with a tight tolerance of +0.0000 to -0.0010 inches for accurate hole sizing
• 118-degree standard point angle with web thinning for reduced entry thrust
• 9-inch flute length and 12-inch overall length for extended reach in deep-hole work
• High-speed steel construction with coated finish for improved wear resistance
• Right-hand spiral flute promotes efficient chip evacuation in steel and cast iron
• Conforms to ASME B94.11M dimensional standards

Compatibility

Rated for drilling alloy tool steel, carbon steel, and cast iron. Straight 1/2 inch shank fits standard drill chucks used in drill presses, hand drills, and magnetic base drills.

Installation Notes

Secure the shank fully in the chuck before operation and verify chuck key is removed prior to starting the machine. Use appropriate cutting fluid or cutting oil when drilling steel or cast iron to extend bit life and maintain hole tolerance. Inspect the cutting edges for wear or chipping before each use, as a dull bit increases thrust and can cause workpiece damage. Follow applicable OSHA and shop safety standards for rotating tool operation, including secure workpiece fixturing.
