Built from solid carbide, it delivers the rigidity and heat resistance required when cutting cast iron, nickel alloys, stainless steel, titanium alloys, and tool steel. The 135-degree split-point geometry reduces walking at entry and lowers thrust requirements, making it well suited for production drilling applications where precision and tool life are priorities. At 2.125 inches overall length, this stubby format limits deflection and suits drill press and CNC machining center work where rigid setups are standard.\u003c\/p\u003e\u003cp\u003eThis drill bit is sized at No. 22 wire gauge, corresponding to 0.1570 inch decimal diameter, and falls within the 0.1500 to 0.2000 inch drill bit size range. It is intended for use in metalworking environments including job shops, aerospace component production, and maintenance shops where stainless steel and nickel alloy materials are regularly machined. The screw machine length format is a common choice in turret lathes, machining centers, and production drill presses where reduced overhang improves hole accuracy and surface finish.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive metals\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces entry walking and cutting thrust\u003c\/li\u003e\n\u003cli\u003eSlow spiral flute design promotes chip control in tough, stringy, or work-hardening materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for applications where coating compatibility or regrinding is a consideration\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks and collets without adapters\u003c\/li\u003e\n\u003cli\u003eScrew machine length minimizes deflection for tighter hole tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw machine length drill bit for use with standard straight-shank drill chucks and collets in drill presses, turret lathes, and CNC machining centers.
