Precision Twist Drill 5998282 Jobber Drill Bit 3/64 in

Product Description

The PRECISION TWIST DRILL 5998282 is a jobber-length twist drill bit designed for general-purpose drilling in metalworking and fabrication applications. Built from high-speed steel with a bright uncoated finish, this bit measures 3/64 inch (0.0469 inch decimal) in diameter with an overall length of 1.75 inches and a flute length of 0.75 inches. The standard 118-degree point angle and web-thinned, tapered web construction allow for efficient chip evacuation and consistent hole entry. With a straight-cylindrical shank and right-hand spiral flute, this bit fits standard drill chucks and is well suited for repetitive production drilling tasks performed by machinists, tool-and-die workers, and maintenance technicians.

The 5998282 is intended for drilling into a broad range of materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Its 16xD flute-to-diameter ratio and regular spiral type make it appropriate for both handheld and machine-mounted drilling setups in light manufacturing, maintenance, and repair environments. The compact jobber length provides good rigidity for small-diameter work where deflection is a common concern. This bit is sold individually but carries a minimum order quantity of 12 units, making it practical for shop stocking.

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard drill chucks accommodating a 3/64 inch straight-cylindrical shank. Suitable for bench drill presses, CNC drill heads, and handheld power drills configured for small-diameter work.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trades professionals familiar with proper drill press or power tool operation. Ensure the workpiece is securely clamped before drilling and that the chuck is tightened fully to prevent bit slippage on small-diameter shanks. At 3/64 inch diameter, the bit is susceptible to breakage if excessive lateral force or feed pressure is applied. Follow applicable shop safety standards and wear appropriate eye protection when operating drilling equipment.
