Built with a 118-degree drill point angle and a fast spiral flute configuration, this bit delivers clean entry and efficient chip evacuation in demanding materials. The tapered web construction adds rigidity at the cutting edge. At 7\/32 inch (0.2187 inch) in diameter with a matching 7\/32 inch shank, the bit fits standard drill chucks and CNC spindles. Overall length is 1-1\/2 inches with a 3\/4 inch flute length. This bit is handled by machinists, PCB fabricators, and maintenance technicians working in high-precision drilling applications.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling cast iron, non-ferrous metals, and plastics, making it applicable across circuit board fabrication, prototype work, and light production runs. The bright polished finish reduces friction and helps with chip flow in shallow-depth holes typical of board and panel drilling. Its compact overall length of 1-1\/2 inches makes it well-suited for drill press and CNC setups where short tool projection is preferred.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in precision drilling\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle for clean, accurate entry in circuit board materials\u003c\/li\u003e\n  \u003cli\u003eFast spiral flute design promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration adds cutting-edge strength\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction with 35-degree helix angle\u003c\/li\u003e\n  \u003cli\u003eBright polished finish reduces friction during drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard drill chucks and CNC spindle toolholders accepting a 7\/32 inch shank.
