Precision Twist Drill 6001872 Jobber Drill Bit No 7

Product Description

The PRECISION TWIST DRILL 6001872 is a jobber-length drill bit designed for general-purpose drilling in metal and hard materials. It is manufactured from high-speed steel with a bright, uncoated finish and features a standard 118-degree point angle with a web-thinned, tapered web configuration. The spiral flute geometry promotes efficient chip evacuation, while the straight-cylindrical shank provides secure seating in standard drill chucks. At 3 inches overall length with a 1.75-inch flute length, this bit suits bench drill presses, hand drills, and CNC drilling setups commonly found in machine shops, maintenance facilities, and fabrication environments. Installation and use are performed by machinists, maintenance technicians, and metal fabricators.

This drill bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, and other hard materials. It is a right-hand cut tool intended for standard rotary drilling applications. The No. 7 wire gauge size corresponds to a decimal diameter of 0.2010 inches, placing it in the 0.2000 to 0.2500 inch drill bit size range. It carries a flute-to-diameter ratio of 9xD and a maximum drilling depth of 1.75 inches, making it appropriate for through-holes and shallow blind holes in production and maintenance drilling tasks.

Installation Notes

Installation is performed by machinists, maintenance technicians, or fabricators using standard drill press or hand-drill equipment. Ensure the machine is fully powered down and the chuck is secured before inserting or removing the bit. Confirm shank seating and chuck tightness before operation. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life and maintain hole quality; note this bit does not support through-coolant delivery.
