High Cleanliness Solid Carbide Flat Bottom Drill Bit 12mm Diameter Internal Coolant

The D10xL55.7xD12xL105 solid HM internal-cooling flat-bottom drill is a 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 a 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.

This tool is mainly used for hole machining in various precision parts in the electronics industry, including micro connectors, IC packaging housings, heat sinks, and micro motor casings. It is suitable for a wide range of materials such as non-ferrous metals (e.g., aluminum alloys), stainless steel, and high thermal conductivity engineering plastics.

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.

• Flat-bottom hole design meets assembly surface requirements for electronic components
• Internal cooling enhances machining efficiency and extends tool life
• High-strength carbide substrate ensures excellent wear resistance and fracture toughness
• Precision dimension control supports stable automated processing
• AMG's rigorous manufacturing guarantees high performance and cost-effectiveness for mass production needs in the electronics sector
