Material: tungsten carbide
Size: 5.5mm*8.0mm+8mm*80mm
Super sharpness and wear resistance.
Used for stainless steel, cast iron, mould steel, carbon steel etc.
Features of solid carbide step twist drill bits include:
1. The drill bit is made of solid carbide, which is a hard and durable material with excellent wear resistance and heat resistance. It is suitable for use on hard materials such as stainless steel, cast iron and high-temperature alloys. drilling.
2. The stepped design allows holes of varying diameters to be drilled using a single drill bit, providing versatility and efficiency in a variety of drilling applications.
3. The spiral groove design helps to effectively remove chips and debris from the hole during drilling, reducing heat accumulation and improving chip evacuation.
4. Solid carbide drill bits are known for their high heat resistance, maintaining cutting performance even at high drilling speeds and temperatures.
5. The drill bit has a precision ground cutting edge to ensure accurate and clean drilling, minimizing the risk of workpiece damage.
6. Solid carbide step twist drill bits are specifically designed for drilling in hard and abrasive materials, making them ideal for applications where standard drill bits may wear out quickly.
