The set spans sizes from \u003cstrong\u003e#1 to #60\u003c\/strong\u003e, offering holes from roughly 0.228 inches down to 0.040 inches (5.79 mm to 1.02 mm). This broad scope supports both delicate pilot work and larger through holes, making it a practical addition to home workshops, garages, and professional shops alike. The bits are engineered for a crisp edge and reliable cutting performance across metals, plastics, and wood.\u003c\/p\u003e\n\n\u003ch3\u003eKey benefits at a glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eWide range of sizes from 0.040 to 0.228 inches, enabling precise incremental drilling\u003c\/li\u003e\n\u003cli\u003eM35 cobalt alloy delivers durability and sharpness for tougher materials\u003c\/li\u003e\n\u003cli\u003e135 degree point tip with self centering twist for faster starts and reduced wandering\u003c\/li\u003e\n\u003cli\u003eHSS cobalt construction with hardened, polished inserts for precise cuts and longer life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eCompatible with stainless steel, iron castings, copper, aluminum, and more, plus plastics and wood\u003c\/li\u003e\n\u003cli\u003eIncludes an index storage case for organized, quick access during projects\u003c\/li\u003e\n\u003cli\u003eEfficient chip and particle removal supports smooth drilling progress\u003c\/li\u003e\n\u003cli\u003eClear guidance to maintain a vertical angle and avoid bit binding for best results\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe set uses M35 cobalt chemistry, known for hardness and heat resistance, helping edges stay sharp through repeated use. The 135 degree tip bites into material with minimal wobble, while the self centering design reduces wandering on small holes. With 60 distinct sizes, you can start with a small pilot and step up to larger holes as needed, adapting quickly to diverse tasks.\u003c\/p\u003e\n\n\u003ch3\u003eReal life use scenarios\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHome workshops drilling stainless steel brackets, aluminum profiles, or copper fittings\u003c\/li\u003e\n\u003cli\u003eDIY projects in wood and plastics where clean entry and precise hole diameter matter\u003c\/li\u003e\n\u003cli\u003eLight fabrication tasks in metalworking, cabinetry, or automotive tweaks\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTips for best results\u003c\/h3\u003e\n\u003cp\u003eBefore drilling, secure the workpiece and ensure the bit is oriented vertically. If a bit binds or stalls, reposition and apply steady downward pressure while keeping alignment with the hole. If a bit becomes lodged, remove it vertically to avoid breakage and repeat as needed.\u003c\/p\u003e\n\n\u003cp\u003eWhether updating a tool kit or tackling a one off project, this MACXCOIP set provides a broad selection of sizes and a durable build that can support a range of everyday tasks while staying organized in the included case.
