Precision Twist Drill 5999215 Jobber Drill Bit Wire 15

Product Description

The PRECISION TWIST DRILL 5999215 is a jobber-length drill bit in wire gauge size 15, with a decimal diameter of 0.1800 inches. It is manufactured from high speed steel with a bright, uncoated finish and a standard 118-degree split point. The bit features a regular spiral flute design with a tapered web and web-thinned geometry for efficient chip evacuation and reduced thrust. With an overall length of 3.375 inches and a straight-cylindrical shank of the same 0.1800-inch diameter, it is a general-purpose drilling tool suited for production and maintenance work across a wide range of metalworking applications.

This bit is designed for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. It is commonly used in machine shops, fabrication environments, and field service applications where wire-gauge sizing is required. The 2-3/16-inch flute length supports a maximum drilling depth of 2.1875 inches, making it effective for through-hole work in standard stock thicknesses. It is part of the PRECISION TWIST DRILL R18P series, which covers general-purpose jobber-length bits in the 0.1500 to 0.2000-inch diameter range and conforms to ANSI standards.

• Regular spiral, 2-flute design promotes chip removal during drilling
• Bright uncoated finish suitable for general-purpose use without surface treatment concerns
• Straight-cylindrical shank fits standard 3-jaw drill chucks and collet systems

Compatibility

Designed as an OEM-style general-purpose jobber-length drill bit compatible with standard 3-jaw drill chucks and collet holders accepting a 0.1800-inch straight-cylindrical shank. Listed under PRECISION TWIST DRILL series R10P, R15P, and R18P for wire-gauge drill applications conforming to ANSI specifications.

Installation Notes

This bit is installed by machinists, maintenance technicians, and metalworking professionals using standard drill presses, CNC machining centers, or hand-held power drills. Ensure the chuck or collet is fully tightened and the workpiece is securely fixtured before operation. Use appropriate cutting fluid or coolant when drilling stainless steel, superalloys, or titanium to extend tool life and prevent work hardening. Inspect the cutting edges for wear before each use and replace the bit if the point shows chipping or rounding.
