Value Collection 1057191 Taper Length Drill Bit 0.5625 in

Product Description

The VALUE COLLECTION 1057191 is a taper length drill bit designed for professionals who need extended reach beyond a jobber-length drill without sacrificing rigidity. Ground from HSS-E Cobalt (M35 material grade), this bit handles harder steels, stainless alloys, and abrasive materials where standard high-speed steel loses its edge prematurely. The 118-degree point angle is a general-purpose geometry suited to a wide range of metals and plastics. At 8.25 inches overall length with a 5.375-inch flute, it provides the depth capacity required for through-hole work on thicker stock. The bright, uncoated finish means no coating interference on close-tolerance bores.

This taper length drill is used in metalworking, maintenance-and-repair, and fabrication environments where standard jobber-length bits fall short. Typical applications include drilling through structural steel, heavy plate, and stainless components in industrial, commercial, and manufacturing settings. Machinists, tool-and-die technicians, and maintenance professionals are the primary installers. The 9/16-inch shank seats in standard drill chucks and is compatible with drill presses, magnetic drills, and rigid-arm machines where runout control matters.

Key Features

• HSS-E Cobalt (M35) construction resists heat buildup when drilling hardened and stainless steels
• 118-degree split-point-compatible geometry provides general-purpose performance across metals and plastics
• Taper length body at 8.25 inches overall gives extended reach compared to jobber-length equivalents
• 5.375-inch flute length supports chip evacuation on deep-hole applications
• Bright, uncoated finish maintains dimensional accuracy without coating buildup in tight-tolerance holes
• 9/16-inch shank diameter matches the bit diameter for direct chuck mounting without adapters

Compatibility

Designed as an OEM-style taper length drill bit for use in standard drill chucks, drill presses, and magnetic base drills accepting a 9/16-inch straight shank.

Installation Notes

Secure the shank fully in the chuck and verify concentricity before drilling to minimize runout and premature edge wear. Use appropriate cutting fluid or coolant when drilling stainless or hardened alloys to extend tool life. Power down and de-energize the machine before changing bits or adjusting chuck pressure. Follow shop safety standards and applicable OSHA machine-guarding requirements when operating drill press equipment.
