DRILL 2.5×D2.5×20×40 – 55 HRC

Description

DRILL 2.5×D2.5×20×40 – 55 HRC is a high-performance solid carbide CNC drilling tool designed for accurate hole making in stainless steel, alloy steel and hardened materials up to 55 HRC. This micro drill is widely used in die and mould machining, aerospace components, auto parts and precision engineering where small-diameter holes with perfect straightness and surface finish are required.

Manufactured from premium micro-grain carbide rod, this drill delivers excellent rigidity, wear resistance and heat stability, allowing it to operate at high spindle speeds without vibration or breakage. The optimized flute geometry provides smooth chip evacuation and low cutting pressure, producing clean, burr-free holes even in tough materials such as SS304, SS316, EN8, EN19 and P20 steel.

With a 2.5 mm cutting diameter, 20 mm flute length and 40 mm overall length, this tool offers the ideal balance between reach and stiffness for deep micro-hole drilling. The parallel shank design ensures strong tool holding and low run-out, improving hole concentricity and repeatability on CNC machines.

This tool is commonly searched as 2.5 mm carbide drill, CNC micro drill, 55 HRC drill, solid carbide drills and precision carbide tools India. It is used by CNC cutting tools manufacturers, die and mould workshops, auto component suppliers and aerospace machining units that need reliable, long-life drilling tools.

Using this 55 HRC carbide drill helps manufacturers reduce tool breakage, improve hole quality and increase productivity in CNC drilling operations.
