Precision Twist Drill 5999224 Jobber Drill Bit 18

Product Description

The PRECISION TWIST DRILL 5999224 is a jobber length drill bit in wire size 18 (0.1695 inches decimal) made from high speed steel with a bright uncoated finish. The bit features a standard 118-degree split point angle and a two-flute right-hand spiral configuration with web thinning for reduced thrust and cleaner entry. At 3.25 inches overall length with a 2.125-inch flute length, this is a general-purpose jobber drill sized for a wide range of production and maintenance drilling tasks. Licensed HVAC, plumbing, and mechanical trades as well as metalworking shops rely on this format for everyday hole-making in metal components.

This bit is designed for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. It is a strong fit for service and fabrication environments where a standard jobber length provides enough flute travel for most common material thicknesses. The 0.1695-inch straight-cylindrical shank seats directly into standard three-jaw keyless or keyed drill chucks without adapters. The R18P series designation places it within the PRECISION TWIST DRILL R10P-R15P-R18P line of general-purpose high speed steel jobber bits.

Installation Notes

Install in a keyed or keyless drill chuck and verify the shank is fully seated before operation. Power down all equipment and secure the workpiece before changing bits. Follow shop safety and applicable ANSI standards for drilling speeds and feed rates based on material type and bit diameter. Do not exceed the 2.125-inch maximum drilling depth without withdrawing to clear chips.
