Precision Twist Drill 5999147 Jobber Drill Bit No 62

Product Description

The PRECISION TWIST DRILL 5999147 is a wire gauge No. 62 jobber length drill bit designed for precision drilling in a wide range of metalworking applications. It is manufactured from high speed steel with a steam oxide coating to reduce friction and resist corrosion during use. The bit measures 1.5 inches in overall length with a 0.625 inch flute length and carries a standard 118-degree drill point angle. Its two-flute spiral design with a web-thinned, tapered web promotes chip evacuation and reduces the thrust needed to start and maintain a cut. This bit is a general-purpose tool suited for use by machinists, maintenance technicians, and trade professionals working with ferrous and non-ferrous metals.

The 5999147 is intended for drilling operations in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Its straight cylindrical shank, at 0.038 inch diameter, fits standard drill chucks without modification. The 0.875 inch shank length provides a secure grip in handheld and bench-mounted drilling equipment. With an ANSI-compliant design and a 16xD flute-to-diameter ratio, it handles general-purpose drilling tasks in production and maintenance settings.

Key Features

• Wire gauge No. 62 size — 0.0380 inch decimal equivalent for precision-diameter hole requirements
• High speed steel construction for durability across a broad range of workpiece materials
• Steam oxide coating reduces friction and provides light corrosion resistance
• 118-degree standard point angle for general-purpose drilling with positive cutting action
• Web-thinned, tapered web reduces thrust and improves chip clearance
• ANSI-compliant Series R18 design with straight-cylindrical shank for universal chuck compatibility

Compatibility

Designed as a general-purpose jobber length drill bit for use in standard drill chucks accepting a 0.0380 inch straight cylindrical shank. Compatible with handheld power drills, drill presses, and CNC drilling equipment. Suitable for workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard drill chuck sized to accept a 0.038 inch shank. Secure the shank fully in the chuck before beginning any drilling operation and confirm the workpiece is clamped or fixtured to prevent movement. Cutting fluid or coolant appropriate to the workpiece material is recommended to extend bit life, though this bit does not support through-coolant delivery. Inspect the cutting edges before each use and replace if chipping or wear is observed.
