Value Collection 1057271 Taper Length Drill 0.625 in Hss-e

Product Description

The VALUE COLLECTION 1057271 is a taper length twist drill bit ground from HSS-E Cobalt (M35 grade) material, designed for drilling through steel, cast iron, stainless, and other ferrous metals that generate elevated cutting heat. The 118-degree split-free point geometry suits general-purpose hole-making in a wide range of workpiece materials. At 0.6250 inches in diameter with an overall length of 8.75 inches, this bit offers the extended reach of a taper length design without sacrificing the rigidity needed for accurate hole location. Machinists, tool-and-die shops, and maintenance mechanics turn to taper length drills when jobber-length bits fall short of the required depth.

This drill bit is suited for use in drill presses, radial arm drills, and CNC machining centers where a 0.6250-inch shank can be held securely in a standard drill chuck or collet. The taper length body provides clearance for deeper holes in plate stock, structural sections, and fabricated assemblies. The bright uncoated finish is standard for M35 cobalt drills and allows the operator to monitor wear during service. General-purpose grade rating makes this bit appropriate for production and maintenance drilling across metal fabrication, HVAC equipment assembly, and mechanical contracting applications.

Key Features

• HSS-E Cobalt M35 construction resists heat buildup during high-feed or interrupted-cut drilling
• 118-degree point angle for general-purpose use across a broad range of ferrous and non-ferrous metals
• Taper length body at 8.75 inches overall provides extended reach versus standard jobber-length bits
• 0.6250-inch shank diameter matches the cutting diameter for direct chuck or collet holding
• Flute length of 5.75 inches allows chip evacuation on deeper through-hole operations
• Bright uncoated finish is compatible with cutting oils and water-soluble coolants without adhesion concerns

Compatibility

Designed as a general-purpose taper length drill bit for use in any machine tool or drill press capable of holding a 0.6250-inch straight shank, including standard drill chucks, keyless chucks, and matching collets.

Installation Notes

Secure the shank fully in the chuck or collet before beginning any drilling operation and verify runout is within acceptable tolerance for the application. Use appropriate cutting fluid or coolant rated for cobalt HSS tooling to maximize tool life and surface finish quality. When drilling deep holes, retract the bit periodically to clear chips and prevent packing. Wear, handling, and storage guidelines for cutting tools should follow the applicable shop safety program and OSHA 1910.212 general machine guarding requirements.
