The D10xL55.7xD12xL105 solid HM internal-cooling flat-bottom drill is high-performance carbide tool developed by AMG specifically for electronic precision component machining.
Made from ultra-fine grain solid HM (hard metal) and equipped with high-efficiency internal cooling channel design, it ensures exceptional bottom flatness and dimensional accuracy even under high-speed and high-stability machining conditions.
This product is particularly suitable for small, precision hole machining requiring high guidance accuracy, cleanliness, and repeatability. It is widely used in the manufacturing of electronic components such as semiconductor packages, sensor housings, and micro-precision enclosures.

Working Principle
The drill uses internal cooling channels to deliver coolant directly to the cutting zone, rapidly dissipating heat and preventing workpiece deformation. Its flat-bottom tip design allows for machining burr-free, taper-free holes, avoiding interference with the assembly surfaces of electronic components and ensuring consistent machining accuracy.
