Internal Cooling Carbide Drill Bit for Hardened Metal Deep Drilling

Our drill bits are made of high-quality tungsten carbide with Swiss PlatIT coating, capable of cutting alloy steel, aluminum alloy, copper, titanium alloy, and high-hardness mold steel. We optimize the tool design for specific materials to ensure optimal performance.

Yes, we do. Our R&D team and application technology center offer one-stop customization services. Please provide your requirements (material, precision, equipment model, etc.), and we will manage the entire process from design and prototyping to mass production.

It depends on the order quantity and complexity. For small-batch non-standard prototypes: 7-10 working days; For bulk production: 15-25 working days. A detailed timeline for large ODM/OEM orders will be provided after order confirmation.

We implement strict full-process quality control. We use German tungsten carbide rods as raw materials, Japanese Makino grinding machines for processing, and German micron-level testing equipment for inspections. Every tool undergoes comprehensive checks before delivery to ensure zero defects.

The service life varies based on the processed material and machining parameters. However, our PlatIT-coated tools offer 2-3 times higher wear resistance than standard tools, reducing replacement frequency and improving overall efficiency.
