Cleveland C70202 Jobber Drill Bit Wire 69 Cobalt

Product Description

The CLEVELAND C70202 is a cobalt jobber length drill bit sized to wire gauge 69, equivalent to 0.0292 inches in decimal. It features a 135-degree split point for accurate self-centering entry and reduced walking on hard or slick surfaces. The gold oxide coating improves surface hardness and heat resistance during high-speed drilling operations. At 1-3/8 inches overall length with a 0.5 inch flute, this bit is designed for precision small-diameter drilling in production and maintenance environments. It carries an M42 cobalt steel grade and meets NAS 907 Type J specification. Licensed HVAC technicians, machinists, and maintenance tradespeople working with tight-tolerance holes will find this bit suited to demanding applications.

This drill bit is intended for use in light-gauge and small-diameter drilling tasks, with a primary workpiece material rating for aluminum. The straight-cylindrical shank fits standard drill chucks without adapters. The regular spiral flute and tapered web configuration promote chip evacuation in shallow to moderate-depth holes. Its heavy-duty grade designation makes it appropriate for repetitive production drilling where standard HSS bits wear prematurely. This is a single-piece package, with orders required in multiples of 12 units.

Key Features

• Wire size 69 (0.0292 inches decimal) with tight diameter tolerance of -0.0005 to 0.0000 inches
• M42 cobalt steel construction for extended tool life in abrasive and harder materials
• 135-degree split point reduces thrust and eliminates center punch requirement on most materials
• Gold oxide coating provides heat and wear resistance during sustained drilling
• Web-thinned, tapered web design improves chip flow and reduces torque
• Meets NAS 907 Type J specification for dimensional and performance consistency

Compatibility

Designed as an OEM-style replacement or direct-use jobber drill bit for standard drill chucks accepting a 0.0292-inch straight-cylindrical shank, rated for aluminum and comparable light-gauge workpiece materials per Series 2213 specifications.

Installation Notes

Installation and use should be performed by qualified machinists or tradespeople familiar with small-diameter drill bit handling. Secure the straight-cylindrical shank firmly in a calibrated drill chuck before operation to prevent runout. At this diameter, excessive feed pressure can cause bit deflection or breakage — use consistent, controlled feed rates. Always wear appropriate eye protection and follow shop safety protocols when operating drilling equipment.
