Cleveland C08885 Taper Length Drill Bit 53/64 in Hss

Product Description

The CLEVELAND C08885 is a taper length, straight-shank drill bit built for general-purpose hole-making in ferrous metals and alloys. Manufactured from high-speed steel with a coated finish, it carries a 118-degree standard point and web-thinned, tapered web geometry that reduces walking and cutting thrust. At 53/64 inch (0.8281 inch) in diameter, this bit bridges the gap between jobber and long-series tooling, giving machinists and fabricators additional reach without sacrificing rigidity. Flute length is 6.125 inches with a 10-inch overall length. Diameter tolerance is held to +0.0000 to -0.0012 inch, consistent with ASME B94.11M and DIN 340 standards.

The C08885 is suited for drilling operations in alloy steel, carbon steel, and cast iron in production and maintenance environments. The taper length body is commonly used in machining centers, drill presses, and manual lathes where a standard jobber-length bit lacks the reach needed to complete a through-hole or step-drill operation. Right-hand spiral flute design clears chips efficiently in the materials listed above. This is a single-piece stock unit with no coolant-through capability, making it appropriate for conventional flood or dry cutting setups.

Key Features

Compatibility

Designed for general-purpose drilling in alloy steel, carbon steel, and cast iron. Compatible with any standard drill chuck or collet system sized to accept a 0.8281-inch straight shank.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or maintenance technicians familiar with rotating tool safety. Secure the shank fully in a properly rated chuck and verify runout before cutting. Power down and lock out the machine before changing tooling. Always operate within the spindle speed and feed rate range appropriate for the workpiece material and bit diameter to prevent premature tool wear or breakage.
