Cleveland C09776 Taper Length Drill Bit 3/4 in Hss

Product Description

The CLEVELAND C09776 is a taper length drill bit built for demanding metal-cutting applications in industrial and trade environments. Part of the Series 950E lineup, it features a 3/4 inch diameter, a 118-degree standard point angle, and a high-speed steel (HSS) construction with a coated finish for improved wear resistance. The spiral flute design and web-thinned, tapered web configuration promote efficient chip evacuation and reduce thrust during drilling. At 12 inches overall length with a 9 inch flute length, this bit is suited for through-hole drilling in thicker workpieces where standard-length bits fall short. Machinists, pipefitters, and ironworkers are the typical users.

This drill bit is designed for general-purpose drilling in alloy tool steel, carbon steel, and cast iron. The straight shank measures 3/4 inch in diameter and 3 inches in length, making it compatible with standard drill chucks and machine spindles. The right-hand cut spiral flute and regular spiral type make this a practical choice for vertical drill presses, radial arm drills, and magnetic base drills used in fabrication shops, mechanical rooms, and field ironwork. It conforms to ASME B94.11M standards.

Key Features

• 3/4 inch diameter with a tight tolerance of +0.0000 to -0.0012 inches for accurate hole sizing
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• 9 inch flute length and 12 inch overall length for deep-reach drilling applications
• High-speed steel construction with coated finish for extended tool life
• Straight shank fits standard drill chucks without adapters
• Conforms to ASME B94.11M dimensional standards

Compatibility

Rated for drilling alloy tool steel, carbon steel, and cast iron. Designed as an OEM-style taper length drill bit compatible with standard 3/4 inch straight-shank drill chucks on bench, floor, and magnetic base drilling equipment.

Installation Notes

Secure the shank fully in the chuck and verify zero runout before drilling. Always power down and lock out the drill press or machine spindle before changing bits. Use appropriate cutting fluid when drilling hardened alloy or tool steel to manage heat buildup and extend tool life. Eye protection and secure workpiece fixturing are required during all drilling operations.
