طقم شفرات التفريغ و الثقب ثنائية المعدن من توتال (TACSH1121) مكونة من (12Pcs) قطعة

Bi-metal means a durable steel backing with a high-speed steel cutting edge. This combination delivers better wear resistance, longer life, and improved performance when cutting through wood, plastic, or metal.

You can cut wood, plastic, and metal with appropriate speeds and techniques. The bi-metal teeth are designed for versatility across common workshop materials.

The kit includes 12 varying hole saw diameters, giving you a range of hole sizes for different tasks.

You’ll typically need a compatible hole saw arbor and a pilot drill bit, along with your drill. These items are not always included in the kit.

Attach a hole saw to a compatible arbor, secure your workpiece, start at a low speed, and apply steady pressure. Use lubricant when cutting metal and wear eye protection.

It's well-suited for electrical outlet and conduit openings, plumbing work, cabinet and furniture work, door hardware clearances, and general non-ferrous or ferrous material cutting.

After use, wipe away chips and moisture, keep the bits dry, and store them in the included case or a dry, organized container to prevent damage and rust.

Compared with other 12-piece bi-metal sets on Fepy (for example TACSH1122, which also offers 12 pieces), TACSH1121 emphasizes bi-metal durability for versatile material cutting. For a different piece count, there are smaller sets like TACSH1101 (6-piece) and larger, multi-count options like TACSH1130 (20-piece).

If you want a similar 12-piece option, you can look at TACSH1122 at https://fepy.com/product/tacsh1122-bi-metal-hole-saw-kit-12pcs. For a smaller set, TACSH1101 is at https://fepy.com/product/tacsh1101-bi-metal-hole-saw-kit-6pcs, and for a larger 20-piece selection, TACSH1130 is at https://fepy.com/product/tacsh1130-bi-metal-hole-saw-kit-20pcs.

For woodworking, use the larger diameters for quick clearance holes in cabinetry or furniture. For metalworking, use slow speeds and lubrication to cut holes in metal profiles or brackets. Always match speed and feed to the material.

The 12-piece set provides a wide range of diameters in one package, saves time from hunting for sizes, and often offers a lower cost per cut than buying each hole saw separately, making it a more efficient choice for varied projects.

Yes. With the right arbor and pilot bit, the variety of sizes and the durable bi-metal construction help achieve clean, accurate cuts for cabinetry openings, electrical boxes, and related installations.
