What this product does Micro drill bits engineered for precise, repeatable drilling in small parts and circuit boards. Built to maintain accuracy and cutting performance under repetitive PCB drilling tasks. Key materials and size Constructed from robust cemented carbide combined with speed steel for hardness and improved wear resistance. Standard 1.5inch length for compatibility with most standard collet systems. Performance advantages Accurate engineering: tight cutting geometry gives consistent hole size and cleaner edges, reducing rework. Chip evacuation design: fluted geometry with enhanced clearance channels directs debris away from the cutting surface, reducing friction during vertical penetration and keeping holes cleaner. Reduced operating stress: progressive edge angles and balanced torsional rigidity lower the risk of sudden fracture when drilling composite materials or encountering unexpected obstructions. Ease of use Colourcoded identification rings make it quick to identify diameters during busy workflows. Universal length works with common collet chucks for straightforward bit changes. Why you need it Delivers durable, repeatable performance for volume or precision microdrilling. Minimizes downtime and bit breakage, saving time on fragile or expensive workpieces. Easier debris removal and stable torque reduce heat and tool wear. Typical applications PCB drilling and electronics prototyping: clean, consistent vias and component holes in printed circuit boards. Precision parts and composites: drilling small holes in composite assemblies, fiberglass, and other layered materials where fracture risk is a concern. Finedetail work: model making, small mechanical components, and tasks that require accurate, smalldiameter holes. Compatibility and handling notes Use with standard collet systems sized for 1.5inch shank length. Match cutting speeds and feed rates to material; lower feeds help reduce stress on micro bits when entering composite layers or hard spots.
