Cleveland C16982 Cobalt Drill Bit No. 30 0.1285 in

Product Description

The CLEVELAND C16982 is a jobber-length drill bit in wire gauge size No. 30, measuring 0.1285 inches in diameter. Built from M42 cobalt high-speed steel and finished with a TiAlN coating, it is engineered for extended tool life in demanding drilling applications. The 135-degree split point reduces walking and cutting force at entry. A parabolic flute geometry improves chip evacuation, reducing the need for peck drilling in deeper holes. The straight-cylindrical shank seats securely in standard drill chucks. This bit is sold individually and is suited for machinists, maintenance technicians, and metalworking tradespeople working in production or field environments.

The C16982 is designed for drilling cast iron and stainless steel, two materials that demand a cobalt alloy bit over standard HSS. The TiAlN coating adds heat resistance, making this bit effective in higher-speed dry or low-coolant cutting conditions where surface temperatures climb quickly. The parabolic flute and web-thinned, tapered web configuration reduce thrust requirements and help clear chips in blind holes. This is a right-hand cut bit appropriate for standard drill press, CNC, or hand-drill applications in fabrication shops, mechanical rooms, and field service.

Key Features

• M42 cobalt steel construction for hardened and abrasive material drilling
• TiAlN coating provides heat resistance and extended cutting life
• 135-degree split point for accurate entry with reduced thrust
• Parabolic flute with web-thinned tapered web for efficient chip removal
• Right-hand cut with straight-cylindrical shank for standard chuck compatibility
• Meets ASME B94.11M and DIN 338 dimensional standards

Compatibility

Designed for use in cast iron and stainless steel workpieces. Fits standard drill chucks accepting a 0.1285-inch straight-cylindrical shank. Part of the Cleveland Series 2075A jobber-length cobalt drill line.

Installation Notes

Installation and use should be performed by qualified machinists or trade technicians familiar with cutting tool setup. Secure the shank fully in the drill chuck and verify runout before starting the cut. Use appropriate cutting fluid or cooling strategy for stainless steel applications to manage heat buildup. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
