Precision Twist Drill 5999272 Jobber Drill Bit Wire 9

Product Description

The PRECISION TWIST DRILL 5999272 is a jobber-length drill bit sized to wire gauge number 9, equal to 0.1960 inches in diameter. Made from high speed steel with a bright uncoated finish, it features a standard 118-degree split-point angle and a regular spiral flute configuration with web thinning for improved chip evacuation and reduced thrust on entry. The overall length is 3.625 inches, and the two-flute design supports efficient material removal in general-purpose drilling applications. Licensed trades and machining professionals reach for this bit when drilling through a range of ferrous and non-ferrous materials in production or maintenance environments.

This bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering ISO material codes P, M, K, N, and S. It is a general-purpose tool appropriate for handheld drills, drill presses, and CNC applications where a straight-cylindrical shank fits the chuck. The 2.4375-inch flute length supports a maximum drilling depth of 2.4375 inches, making it a practical choice for through-hole and moderate-depth drilling in sheet metal fabrication, maintenance repair, and light manufacturing.

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any drill press, handheld power drill, or CNC spindle accepting a straight-cylindrical shank of 0.1960 inches in diameter. Part of the R10P-R15P-R18P series from PRECISION TWIST DRILL.

Installation Notes

Secure the shank fully in the chuck before drilling and confirm the workpiece is clamped or fixtured to prevent rotation. Power down and de-energize any machine tool before changing bits. Use appropriate cutting fluid or coolant when drilling stainless steel, titanium, or hardened alloys to extend bit life, noting this bit does not have an internal coolant channel. Inspect the cutting edges before each use and discard or resharpen bits showing chipping or excessive wear.
