Built from high speed steel (HSS) with an oxide coating, it carries a No. 16 wire gauge size, equivalent to 0.1770 inches in decimal. The 135-degree split point geometry reduces walking on entry and lowers the thrust required to start a hole. The web-thinned, tapered web construction improves chip evacuation and cutting efficiency. With an overall length of 2.125 inches and a flute length of 1.125 inches, this bit is suited for tight-clearance applications where compact tooling is required. The 1\/4-28 threaded hex shank provides secure tool retention in compatible quick-change systems.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in metal fabrication, maintenance, and production drilling operations where a No. 16 wire size hole is specified. Its NAS 965 specification rating makes it appropriate for aerospace-adjacent and general industrial applications involving low-tensile strength materials such as aluminum, soft steel, and similar alloys. Right-hand cutting with a regular spiral flute pattern suits standard bench drill presses and hand-held drilling equipment. The threaded shank design is particularly useful in torque-sensitive applications requiring positive shank engagement rather than a smooth slip-fit chuck.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 16 wire size, 0.1770 inches decimal equivalent for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces drill walk and lowers entry thrust\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web improves chip clearing and cutting performance\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with oxide coating for wear resistance\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 threaded hex shank for positive retention in quick-change systems\u003c\/li\u003e\n  \u003cli\u003eNAS 965 specification compliance for controlled industrial and aerospace-adjacent use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with quick-change tool holders and drill drivers that accept a 1\/4-28 threaded hex shank.

Ensure the threaded shank is fully seated and torqued into the compatible tool holder before operation. Verify spindle speed is appropriate for the material and bit diameter before starting the cut.
