Product Description
The Multi-tooth Carbide Hole Saw is specifically engineered for the most demanding metal-cutting tasks, particularly for stainless steel pipes and thick plate materials. By increasing the tooth count and optimizing the rake angle, we have created a tool that provides exceptional stability and cutting speed. This "TCT" (Tungsten Carbide Tipped) tool features a ground center positioning drill that ensures zero drifting during startup. In our Yueqing factory, we utilize a proprietary welding process to fuse the carbide teeth to the alloy body, ensuring they withstand high-load industrial use without shattering or dulling prematurely.
As a modern manufacturing enterprise, we understand that professional-grade tools like the Multi-tooth Carbide Hole Saw must perform consistently in the field. Our "closed-loop" production system ensures that the 100% inspection we perform in our 6,000sqm facility translates into a "zero-defect" experience for your end-users. We offer these saws in a wide range of specifications, from 16mm up to 32.5mm, all featuring our signature triangular non-slip shank. For our global partners, we provide professional pre-sales consultation to ensure you select the right tooth count and diameter for your specific market demands.

FAQ
Q: Why is it not recommended for lithium or impact drills?
A: For the Multi-tooth Carbide Hole Saw to cut effectively in metal, it requires high torque and stable RPM which small lithium drills often lack. High-power bench or hand drills provide the best results.
Q: Are samples free?
A: We can provide samples for quality evaluation; please contact our sales team for the specific sample policy.
