Value Collection 301-1004 Cobalt Drill Bit Set 16 Pc

Product Description

The VALUE COLLECTION 301-1004 is a 16-piece reduced shank cobalt drill bit set built for metalworking and heavy-duty drilling applications. Each bit is manufactured from cobalt tool steel with an oxide coating for improved heat and wear resistance. The set covers sizes from 9/16 inch up to 1-1/2 inch in 1/16-inch step increments, giving technicians a complete range for drilling oversized holes in metal without changing shank sizes. The 135-degree split point angle reduces walking and requires less feed pressure at startup. Bits store in an included plastic case for jobsite organization. Total set weight is 1 pound.

This set is designed for metalworking and multipurpose drilling tasks in trade and industrial environments. Reduced shank geometry allows larger diameter bits to fit standard drill chucks, making the set practical for machinists, maintenance mechanics, pipefitters, and fabricators who need to drill holes up to 1-1/2 inches without a dedicated large-shank drill press setup. The heavy-duty cobalt construction handles harder steels, stainless, and high-temperature alloys where standard HSS bits fail prematurely.

Key Features

• Cobalt tool steel construction with oxide finish for heat and wear resistance in hard-metal drilling
• 135-degree standard point angle reduces bit walking and lowers required feed force
• Reduced shank design allows use in standard drill chucks across the full size range
• 16-piece set covers 9/16 inch to 1-1/2 inch in 1/16-inch increments
• No coolant-through requirement — suitable for dry or manually lubricated drilling
• Plastic storage case keeps bits organized and protected between uses

Compatibility

Designed as an OEM-style replacement or general-use reduced shank drill bit set for standard drill chucks used in metalworking, fabrication, and maintenance applications measured in inch increments.

Installation Notes

Installation of this drill bit set should be performed by qualified machinists, maintenance mechanics, or trade professionals familiar with drill press and hand-drill operation. Always secure the workpiece and verify the chuck is properly tightened before operation. Use appropriate cutting fluid or lubricant when drilling hard metals to extend bit life and reduce heat buildup. Inspect each bit for chipping or wear before use and replace any damaged bits before continuing work.
