Cleveland C09723 Extra Length Drill Bit 3/8 in Hss

Product Description

The CLEVELAND C09723 is an extra length high-speed steel drill bit designed for deeper drilling and long-reach applications where standard-length bits cannot reach. Built to Series 950E specifications, this bit features a 3/8-inch diameter, a 118-degree standard point angle, and a spiral flute configuration with web thinning for improved chip evacuation and reduced thrust at the cutting tip. The oxide finish provides moderate corrosion resistance and helps retain cutting fluid during operation. At 10 inches overall length with a 7.5-inch flute length, it gives technicians and machinists the reach needed for deep-hole work in tight or extended-access setups.

This drill bit is suited for production and maintenance drilling in cast iron and steel workpieces where standard-length tooling falls short. Typical applications include deep-hole drilling in structural steel, fabrication work, and mechanical maintenance scenarios requiring extended reach. The straight cylindrical shank accepts standard drill chucks without adapters, making it compatible with handheld drills, drill presses, and milling machine setups. Right-hand cutting direction and a regular spiral type make it a general-purpose choice across a range of shop and field conditions.

Key Features

• Extra length design at 10 inches OAL for deeper drilling and long-reach access
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High-speed steel construction rated for cast iron and steel primary workpiece materials
• Oxide finish for corrosion resistance and improved lubrication retention
• 7.5-inch spiral flute length promotes efficient chip clearing in deep holes
• Diameter tolerance of +0.0000 to -0.0010 inches for consistent hole sizing
• Straight cylindrical shank fits standard chucks without additional tooling

Compatibility

Designed for use in standard 3/8-inch drill chucks on handheld drills, drill presses, and milling machines. Primary workpiece materials are cast iron and steel. Conforms to ASME B94.11M and ANSI standards.

Installation Notes

Installation and use should be performed by qualified machinists or tradespeople familiar with rotary cutting tools. Secure the workpiece fully before drilling and ensure the shank is seated and tightened in the chuck before operation. Do not exceed the recommended speed and feed for the workpiece material and bit diameter. Consult applicable shop safety standards and OSHA guidelines when operating drilling equipment.
