Cleveland C15925 Cobalt Drill Bit 5/32 Inch 135 Degree

Product Description

The CLEVELAND C15925 is a cobalt jobber length drill bit designed for demanding metal drilling applications in trade and industrial settings. Built from M42 cobalt high-speed steel with an oxide coating, this bit delivers extended tool life when cutting superalloys, stainless steel, and other hard metals. It features a 135-degree split point for fast engagement with minimal walking, and a fast spiral flute geometry that evacuates chips efficiently. The straight-cylindrical shank provides secure grip in standard drill chucks. This is a heavy-duty bit intended for use by machinists, pipefitters, electricians, and other trade professionals who drill frequently into tough materials.

The C15925 is suited for production and maintenance drilling in residential and commercial settings where hard or exotic metals are encountered. Its 5/32-inch diameter makes it a common size for pilot holes, anchor clearances, and fastener holes in sheet metal and structural components. The jobber length profile balances reach and rigidity for general-purpose work. Web-thinned geometry reduces thrust requirements, making it practical for hand drills and drill presses alike.

Key Features

• M42 cobalt steel construction for high heat resistance and extended tool life in hard materials
• 135-degree split point reduces walking and allows faster penetration without a center punch
• Oxide coating provides corrosion resistance and mild lubricity
• Fast spiral flute with web thinning improves chip evacuation and reduces feed force
• Straight-cylindrical shank fits standard 3-jaw drill chucks
• Conforms to ASME B94.11M and NAS specification designation

Compatibility

Designed as a heavy-duty jobber length drill bit for use with standard drill chucks accepting a 5/32-inch straight-cylindrical shank; primary workpiece material rating is superalloy, with general applicability to stainless steel and other hard metals.

Installation Notes

Install into a keyed or keyless drill chuck and tighten securely before operation. Use cutting fluid or coolant when drilling hard metals to preserve edge life, even though this bit does not support through-coolant. Ensure workpiece is clamped or fixtured before drilling to prevent movement. Follow applicable shop safety practices and OSHA guidelines for rotating tool use.
