Total TAC410461 46MM Bi-Metal Hole Saw

This hole saw is offered in multiple diameters to cover a range of hole sizes. Choose the diameter that matches your project needs.

Bi-metal hole saws have high-speed steel teeth welded to a flexible steel back, providing greater durability, faster cutting, and resistance to tooth wear compared with traditional carbon-steel hole saws.

Mark the hole location, attach the hole saw to the drill via an appropriate arbor, and use a pilot bit if included. Drill at a slow-to-medium speed with steady, straight pressure, back out periodically to clear debris, and use a backing board to prevent tear-out on delicate surfaces.

Wear eye protection, secure the workpiece with clamps, keep hands clear of the cutting area, avoid overheating by not forcing the cut, and use cutting fluid for metal if appropriate. Always ensure the drill is off before changing accessories.

It's suitable for DIY and professional work, such as installing door hardware, cutting openings for pipes, plumbing and electrical work, cabinetry and furniture modifications, and general hole-making tasks.

Select the appropriate arbor for the hole saw, slide the hole saw onto the arbor, secure it with the nut, attach the pilot bit if included, and ensure everything is aligned and tightened before drilling.

Yes, it is designed to fit standard drill chucks. Depending on your setup, you may need an appropriate arbor or pilot bit to secure the hole saw properly.

Compared to a carbide-tipped hole saw, this bi-metal version offers excellent durability and fast cutting across wood, metal, and plastic. For harder materials, carbide-tipped options on Fepy may perform better, while standard HSS or basic bi-metal sets can be more economical for light-duty tasks. Alternatives available on Fepy include: Total Bi-Metal Hole Saw Set (https://fepy.com/products/total-bi-metal-hole-saw-set), Carbide Tipped Hole Saw (https://fepy.com/products/carbide-tipped-hole-saw), and HSS Bi-Metal Hole Saw (https://fepy.com/products/hss-bi-metal-hole-saw).

Yes. The bi-metal construction offers durability and versatility across common materials, making it a cost-effective choice for a wide range of projects, from home DIY to professional work.

Keep the tooth area clean after use, remove debris from the teeth, store in a dry place, and avoid overheating by drilling at appropriate speeds and with steady pressure. Inspect the teeth for chips or dullness and replace if needed.
