Precision Twist Drill 5999694 Jobber Drill Bit 1.95 Mm

Product Description

The PRECISION TWIST DRILL 5999694 is a cobalt jobber-length drill bit designed for general-purpose drilling in steel and other metallic workpiece materials. It features a 135-degree split point with web thinning to reduce walking and lower thrust at entry. The straw oxide finish provides mild lubricity and corrosion resistance during cutting. At 1.95 mm (0.0768 inches) in diameter with an overall length of 1-59/64 inches (1.9219 inches), this bit fits standard drill chucks and collets without modification. The straight cylindrical shank and two-flute regular spiral design make it a reliable stock item for machine shops, maintenance trades, and precision metalworking applications.

This drill bit is suited for drilling ferrous metals including steel as well as non-ferrous materials consistent with P, M, K, N, and S workpiece material codes under DIN 338 classification. It performs in both handheld and machine-mounted operations such as drill presses, CNC machining centers, and benchtop drilling setups. The 12xD flute-to-diameter ratio and 15/16-inch flute length (0.9375 inches) support chip evacuation in short-depth through-hole and blind-hole applications. Maximum recommended drilling depth is 0.9449 inches. This bit is a Series 2ACO offering, built to ANSI and DIN 338 standards for dimensional consistency.

Installation Notes

This bit is installed by machinists and maintenance technicians using standard chuck or collet tooling. Ensure the drill press, lathe, or CNC spindle is fully stopped and locked out before changing or seating the bit. Verify chuck jaw seating and runout before starting a cut. Do not exceed the recommended maximum drilling depth of 0.9449 inches without retracting to clear chips.
