Value Collection 301-1002 Cobalt Drill Bit Set 6 Pc

Product Description

The VALUE COLLECTION 301-1002 is a 6-piece reduced shank cobalt drill bit set built for heavy-duty metalworking applications. Cobalt construction provides superior heat resistance and hardness compared to standard high-speed steel, making these bits well-suited for drilling into stainless steel, cast iron, and other hard metals. The 135-degree split point angle reduces walking and allows for faster penetration without a center punch. Each bit features an oxide finish and a reduced shank design that allows larger-diameter bits to fit standard 3-jaw chucks. This set is a working tool for machinists, pipefitters, plumbers, and HVAC techs who drill oversized holes through hard materials on the job.

This set covers a range from 7/8 inch to 1-1/2 inch in 1/8-inch step increments, giving tradespeople the sizes needed for common large-diameter hole requirements in metalworking and multipurpose drilling tasks. The bits ship in a plastic storage case that keeps each size organized and protected between uses. Appropriate for both shop and field use where consistent, clean holes in hard material are required.

Key Features

• Cobalt tool material for high heat resistance and extended bit life in hard metals
• 135-degree standard split point angle reduces bit walking on entry
• Reduced shank design fits standard drill chucks despite large cutting diameters
• Oxide finish improves lubricity and corrosion resistance
• 6-piece set spans 7/8 inch to 1-1/2 inch in 1/8-inch increments
• Includes plastic storage case for organized transport and storage

Compatibility

Designed for inch-system metalworking and multipurpose drilling applications. Reduced shank geometry allows use with standard 3-jaw drill chucks across a range of corded and benchtop drilling equipment.

Installation Notes

Installation of these bits should be performed by qualified tradespeople familiar with drill press or hand drill operation. Secure the workpiece firmly before drilling and use appropriate cutting fluid when working hard metals to extend bit life and prevent overheating. Inspect the chuck and bit shank for secure seating before operation. Follow applicable shop safety protocols and applicable codes for the work environment.
