The 12 in overall length (OAL) with a 3-5\/8 in flute length provides deep-reach access for drilling in confined or deep-cavity applications typical of aerospace, automotive, and structural fabrication work where standard-length drills cannot reach. The 135° split point self-centers on contact, eliminating the need for a pilot hole and significantly reducing walking on curved or irregular surfaces. The straight shank is compatible with standard drill chucks and quick-change extension adapters. M42 cobalt construction delivers increased red hardness and heat resistance compared to M2 HSS, making this drill well-suited for harder alloys including stainless steel, titanium, and high-strength structural steels.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid #85c94f;padding-bottom:6px;\"\u003eProduct
