Cleveland C08726 Taper Length Drill Bit No. 3 Hss

Product Description

The CLEVELAND C08726 is a taper length, straight-shank drill bit designed for general-purpose hole-making in ferrous and non-ferrous metals. Built from high-speed steel with a coated finish, it carries a No. 3 wire gauge size equivalent to 0.2130 inch diameter. The 118-degree standard point angle suits a wide range of production drilling tasks. With a 3-5/8-inch flute length and a 6-inch overall length, this bit reaches deeper than a jobber-length tool without requiring an extended-length shank, making it a practical choice for machinists and maintenance techs dealing with moderate-depth bores in plate or block stock.

The C08726 is suited for drilling alloy steel, carbon steel, and cast iron in both shop and field environments. The right-hand spiral flute and web-thinned, tapered web design promote chip evacuation and reduce thrust at breakthrough. A straight shank at 0.2130 inch diameter seats directly into standard drill chucks on drill presses, CNC machining centers, and hand-held electric drills. This bit fits production, toolroom, and MRO applications where a longer reach than a standard jobber bit is required but a full extra-long series is unnecessary.

Key Features

• No. 3 wire gauge size, 0.2130 inch diameter, tolerance +0.0000 to -0.0007 inch
• 118-degree standard point with web-thinned, tapered web for reduced thrust
• High-speed steel construction with coated finish for heat and wear resistance
• 3-5/8-inch flute length provides deeper reach than standard jobber-length bits
• Right-hand spiral flute geometry promotes chip evacuation in blind and through holes
• Straight shank at 0.2130 inch diameter fits standard three-jaw drill chucks
• Meets ASME B94.11M and DIN 340 standards

Compatibility

Designed for drilling alloy steel, carbon steel, and cast iron. Compatible with any standard drill chuck accepting a 0.2130-inch straight shank. Suitable for drill presses, machining centers, and portable electric drills used in general-purpose production and MRO applications.

Installation Notes

Secure the shank fully in the drill chuck and verify runout before beginning a cut. Power down and de-energize any machine tool completely before changing tooling. Use appropriate cutting fluid or coolant on harder alloy steels and cast iron to extend tool life, noting that this bit does not support through-coolant delivery. Follow applicable OSHA machine guarding requirements and shop safety protocols when operating drill presses or machining centers.
