Precision Twist Drill 5998648 Jobber Drill Bit 1/16 in Hss

Product Description

The PRECISION TWIST DRILL 5998648 is a jobber-length drill bit designed for general-purpose drilling in a wide range of materials. Built from high speed steel with a steam oxide coating, it measures 1/16 inch (0.0625 inch) in diameter and 1.875 inches in overall length. The 118-degree standard point angle and web-thinned, tapered-web construction reduce entry force and improve centering on the workpiece. Two spiral flutes with a regular helix clear chips efficiently during drilling operations. This bit is sized for use in hand drills, drill presses, and machining centers by machinists, maintenance technicians, HVAC installers, plumbers, and electricians who need a reliable small-diameter bit for pilot holes, sheet metal, and precision drilling tasks.

This bit suits residential and commercial applications where drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials is required. The straight-cylindrical shank is compatible with standard 3-jaw chucks across a broad range of drill and machining equipment. It is well suited for pilot-hole work, fixture drilling, and light fabrication tasks common in trade and industrial settings. The 14xD flute-to-diameter ratio supports deeper penetration relative to bit size.

Key Features

• High speed steel construction with steam oxide coating for corrosion resistance and reduced friction
• 118-degree standard point angle with web-thinned, tapered-web geometry for accurate starting and reduced thrust
• Two spiral flutes at regular helix for efficient chip evacuation
• Straight-cylindrical shank fits standard 3-jaw chucks without adapters
• Right-hand cut direction for use with conventional clockwise-rotating drill equipment
• ANSI-compliant Series R10 general-purpose jobber-length specification

Compatibility

Designed as an OEM-style general-purpose jobber-length drill bit compatible with any standard 3-jaw chuck accepting a 1/16-inch straight-cylindrical shank, including bench drill presses, hand drills, and machining center tooling holders.

Installation Notes

This bit is installed and used by machinists, maintenance technicians, and licensed trade professionals working with drill presses or hand-held drilling equipment. Secure the straight-cylindrical shank firmly in a properly sized 3-jaw chuck before operation. Always power down and de-energize any drill press or machine tool before changing bits. Use appropriate cutting fluid or coolant when drilling hard materials such as stainless steel or superalloys to extend bit life and maintain cutting edge integrity.
