MICRO DRILL 0.30xD3x5.5×38

Description

Micro Drill 0.30×D3×5.5×38 is an ultra-precision solid carbide micro drilling tool designed for producing very small, high-accuracy holes in advanced CNC machining applications. With a 0.30 mm cutting diameter, this micro drill is ideal for electronics, medical components, micro-moulds, aerospace parts, and precision mechanical assemblies where tight tolerances and perfect hole geometry are critical.

Manufactured from premium sub-micron carbide rod, this micro drill delivers exceptional rigidity, edge sharpness, and wear resistance, even at extremely high spindle speeds. The optimized flute design allows smooth chip evacuation, reducing heat buildup and minimizing the risk of tool breakage during deep or high-speed drilling. This makes it suitable for drilling stainless steel, copper, brass, aluminum, plastics, and medium-hard steels up to 55 HRC.

The D3 shank provides strong clamping and low run-out in high-speed tool holders, while the 5.5 mm flute length and 38 mm overall length offer excellent stability and control for micro-hole drilling. This ensures straight holes, accurate depth, and burr-free finishes in delicate components.

The Micro Drill 0.30×D3×5.5×38 is widely used in CNC cutting tools manufacturers, industrial cutting tools suppliers, and precision carbide tools India markets for applications such as PCB drilling, injector nozzles, watch parts, die and mould micro-features, and fine mechanical assemblies. It supports both high-speed CNC machining and batch production, providing consistent performance and longer tool life compared to conventional HSS micro drills.

This tool is compatible with VMCs, high-speed CNC spindles, and Swiss-type machines, delivering reliable micro-drilling even in difficult materials. It is an essential tool for workshops that demand precision, repeatability, and clean micro-hole quality.
