Our annular drill bit set supports quick disassembly of the drill bit in just 1 second, with no need for any tools. It is particularly suitable when you can't spare an extra hand during high-altitude work. You can quickly replace the drill bit with just one hand.

The blade consists of pointed and flat blades, ensuring a reasonable load distribution for efficient cutting. Our mag drill bits rapidly dispose of cutting chips and waste, reducing resistance from chip accumulation and lowering energy consumption during cutting.

Our HSS mag drill bits can be widely used in steel structures, bridge construction, shipbuilding, drilling platforms, railway construction, and mechanical manufacturing for cutting various materials such as structural steel, alloy steel, stainless steel, aluminum, brass, cast iron, and more.

Selecting the appropriate speed can extend the annular cutter's lifespan. Excessive speed can cause heat damage and wear on the tool's surface, reducing longevity.
