Value Collection 1057099 Taper Length Drill 0.4844 in

Product Description

The VALUE COLLECTION 1057099 is a taper length drill bit ground from HSS-E Cobalt (M35/M42 material grade) with a 118-degree split-point angle and a bright, uncoated finish. At 0.4844 inches (31/64 inch) in diameter, it is sized for general-purpose drilling in steel, cast iron, stainless steel, and other ferrous and non-ferrous materials where standard-length bits lack the reach. The cobalt alloy construction provides increased heat and wear resistance over standard HSS, making it well suited for production drilling or work in harder materials. The taper length body gives extra reach without sacrificing rigidity.

This drill bit is used in machine shop, maintenance, and fabrication environments where a 31/64-inch hole at depth is required. The 5-inch flute length and 7.75-inch overall length accommodate workpieces too thick for jobber-length bits. It fits standard drill chucks and spindles accepting a 31/64-inch straight shank. General-purpose grade designation makes it appropriate for a wide range of drilling applications across light manufacturing, mechanical contracting, and trade service work.

Key Features

• HSS-E Cobalt construction (M35/M42 grade) for elevated heat and wear resistance
• 118-degree drill point angle for general-purpose drilling in a broad range of materials
• 5-inch flute length provides chip clearance over extended-depth holes
• 7.75-inch overall length offers reach beyond standard jobber-length drills
• Bright, uncoated finish allows visual inspection of the cutting edge condition
• 31/64-inch diameter shank matches the drill diameter for direct chuck mounting

Compatibility

Designed as a general-purpose taper length drill bit compatible with standard drill chucks and spindles accepting a 31/64-inch straight shank diameter.

Installation Notes

This drill bit is installed by machinists, millwrights, and trade professionals using standard drill presses, milling machines, or hand-held magnetic drills with appropriate chuck capacity. Ensure the shank is fully seated and the chuck is tightened before operation. Use cutting fluid appropriate to the workpiece material to extend tool life and manage heat buildup. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
