Built from high speed steel with a bright uncoated finish, it measures 0.302 inches in diameter and carries a 118-degree standard point angle. The shortened screw machine length body provides added rigidity over jobber-length bits, reducing deflection in close-tolerance work. Two spiral flutes with a regular helix handle chip evacuation efficiently across a range of ferrous and non-ferrous materials. Web thinning reduces thrust requirements at the point, making it a reliable choice for production drilling.\u003c\/p\u003e\u003cp\u003eThis bit is suited for use in drill presses, CNC machining centers, and manual screw machines where a rigid, compact bit is preferred. Primary workpiece materials include cast iron, non-ferrous metals, and steel. The straight cylindrical shank fits standard drill chucks without adapters. The Series 157 designation places it within a general-purpose line appropriate for maintenance shops, fabrication facilities, and production floor applications. A single-piece packaging makes it easy to stock individually or in small quantities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.302 inch (Letter N) diameter with a tolerance of +0.0000 to -0.0010 inches for close-fit hole work\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web thinning to reduce entry thrust on cast iron and steel\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction handles moderate heat and abrasion in general machining applications\u003c\/li\u003e\n\u003cli\u003eScrew machine length body at 2-13\/16 inches overall increases rigidity and reduces deflection\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute, 1-5\/8 inch flute length promotes consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight hand cut, straight cylindrical shank fits standard drill chucks directly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard stock bit for general-purpose metal drilling applications in drill presses, screw machines, and CNC equipment accepting straight cylindrical shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this bit should be performed by qualified machinists or tool and die professionals familiar with cutting tool setup.
