What is the Warranty for the tungsten carbide products?
We own high precision grading machine to control geometry dimensions and apply ultra fine grain size substrate coated with high performance coatings to guarantee the lifetime of our products, which can satisfy every working condition. If any quality problems on our side occurred in this period, we will take on the shipping cost and replacement.
What is the hardness level and material of these drill bits?
These drill bits are crafted from top-grade WC-Co tungsten carbide raw materials, offering a high hardness level of HRA 89-92 (Rockwell 90+), along with excellent wear and impact resistance.
What materials are these carbide drill bits suitable for?
They are designed for high-speed, high-precision drilling on a wide range of materials, including stainless steel, high-hardness alloy steel, carbon steel, cast iron, aluminum alloy, and non-ferrous metals.
What professional PVD coatings can be chosen?
Optional PVD coatings include TiN (Gold), TiCN (Gray), AlTiN (Purple), and CrN. These coatings reduce friction, enhance wear resistance, and extend the drill bits' service life by 3-5 times.
What dimensions and customizable options are available?
The standard diameter range is 0.5mm - 20mm, and the length range is 10mm - 200mm with straight shanks. Customizable options include custom diameters, lengths, shank types (such as straight or morse taper shanks), and specific coatings to match different industrial requirements.
What packaging specifications and gross weights are standard for shipping?
The standard export packaging measures 350.00cm * 250.00cm * 180.00cm with a package gross weight of approximately 5.500kg.
