The EAGLE CUTTING TOOL TAP50-DBC29-I is a cobalt drill bit set spanning 1/16 inch to 1/2 inch in 64th-inch increments, packaged as the Drill Buddy Import configuration. Cobalt construction provides elevated heat resistance and hardness compared to standard high-speed steel, making this set well suited for drilling into harder metals, stainless steel, and other demanding materials encountered in trade and industrial applications. The incremental sizing range gives technicians and tradespeople a broad selection of drill diameters without the need for multiple separate sets. Licensed electricians, HVAC technicians, plumbers, and pipefitters regularly reach for cobalt sets when working with metal studs, electrical enclosures, pipe flanges, and mechanical equipment.
This set is appropriate for use in residential and commercial job site environments where a wide range of drill sizes is needed in a single kit. The 1/16 inch through 1/2 inch by 64ths range covers the majority of pilot holes, clearance holes, and anchor holes common in mechanical, electrical, and plumbing rough-in work. The cobalt material composition makes it a practical choice when encountering work-hardened metals or when drilling into equipment housings that standard twist bits struggle with.
Designed for use in standard 3-jaw drill chucks accepting round-shank bits up to 1/2 inch, compatible with corded and cordless drills and drill presses commonly used in trade applications.
Cobalt drill bits should be installed by a qualified tradesperson familiar with proper drilling techniques for the material being worked. Always secure the workpiece and verify the drill chuck is properly tightened before operation. Use appropriate cutting fluid when drilling hard metals to extend bit life and reduce heat buildup. Follow applicable safety standards and wear appropriate personal protective equipment including eye protection during drilling operations.
