Cleveland C16972 1/16 Inch Cobalt Jobber Drill Bit

Product Description

The CLEVELAND C16972 is a cobalt jobber-length drill bit designed for drilling hard and abrasive materials in demanding trade applications. Built to M42 cobalt steel grade and coated with TiAlN for extended tool life, this bit runs a 135-degree split point that reduces walking and cutting pressure at entry. The parabolic flute geometry improves chip evacuation, which is critical when drilling deep holes in tough stock. At 1-7/8 inches overall length with a 7/8-inch flute length, this is a standard jobber-length configuration suited for handheld or machine drilling. The 1/16-inch diameter straight-cylindrical shank fits standard drill chucks without modification.

This bit is rated for cast iron and stainless steel as primary workpiece materials, making it a practical choice for plumbers, HVAC technicians, electricians, and pipe fitters who regularly drill through hard ferrous stock. The heavy-duty grade designation and TiAlN coating make it appropriate for repeated use in production or field service environments where standard HSS bits wear prematurely. The right-hand cutting direction is compatible with all standard rotary drills and drill presses. Web-thinned and tapered web configuration reduces thrust requirements, which is especially useful at small diameters like 1/16 inch where bit deflection is a concern.

Key Features

• M42 cobalt steel construction for heat resistance and hardness retention in tough materials
• TiAlN coating extends tool life when drilling stainless steel and cast iron
• 135-degree split point reduces bit walking and lowers entry thrust
• Parabolic flute design promotes efficient chip evacuation during deep drilling
• Web-thinned tapered web reduces cutting resistance at small diameters
• Meets ASME B94.11M and DIN 338 standards for dimensional accuracy and performance

Compatibility

The C16972 is designed for use in standard drill chucks accepting a 1/16-inch straight-cylindrical shank. Primary workpiece materials are cast iron and stainless steel. It is part of the Cleveland 2075A series of TiAlN-coated cobalt jobber-length drill bits.

Installation Notes

This bit is installed by a licensed technician or qualified tradesperson using a standard keyless or keyed drill chuck. Ensure the drill is powered off and secured before changing bits. Use appropriate cutting fluid or coolant when drilling stainless steel to preserve coating life, noting that this bit does not support internal coolant-through delivery. Comply with applicable OSHA and shop safety requirements for rotating tool use.
