ريشة منشار ثقب ثنائي المعدن قياس (44mm) موديل (GL53310)

It uses bi-metal construction with high-speed steel teeth (HRC 65–68) for enhanced durability and cutting efficiency, with an alloy steel sheet body for added strength.

The hole saw has a 44mm diameter, suitable for medium to large holes in wood, plastic, and non-ferrous metals.

The specialized tooth design paired with heat-resistant teeth helps maintain sharpness during cutting, delivering faster cuts and longer tool life even under demanding use.

Yes. It’s designed for wide compatibility and can be used with standard drill chucks and arbor systems.

1) Attach the hole saw to a compatible arbor and secure it in your drill chuck. 2) Clamp the workpiece firmly. 3) Start at a low speed with steady feed, then increase speed gradually as cutting improves. 4) Periodically withdraw to clear chips and prevent clogging. 5) Stop and inspect the teeth if you notice excessive vibration or dulling.

Use appropriate drill speed for the material (lower speeds for metal, moderate speeds for plastic/wood), apply steady pressure without forcing the tool, keep the workpiece clamped, and use a sharp arbor and new teeth if cutting becomes slow.

Wear eye protection and gloves, clamp the workpiece securely, keep hands away from the spinning tool, and avoid overheating the teeth by taking breaks to cool if cutting dense materials. Maintain a clean workspace to prevent accidents.

Perfect for creating holes for electrical outlets, plumbing, venting, or any project requiring a 44mm opening in wood, plastics, or non-ferrous metals.

SATA offers a family of bi-metal hole saws with similar tooth design and durability. For larger holes, you might consider the 52mm variant; for smaller holes, the 33mm variant. Here are examples of comparable options on Fepy: SATA GL53311 Bi-Metal Hole Saw 52mm — https://fepy.com/products/sata-gl53311-bi-metal-hole-saw-52mm; SATA GL53312 Bi-Metal Hole Saw 33mm — https://fepy.com/products/sata-gl53312-bi-metal-hole-saw-33mm; SATA GL53313 Bi-Metal Hole Saw 44mm Turbo — https://fepy.com/products/sata-gl53313-bi-metal-hole-saw-44mm-turbo

Consider the target hole diameter, the material being cut, and the required cutting speed. For larger openings, a larger diameter variant reduces number of passes; for small openings, a smaller diameter minimizes material waste and can provide cleaner cuts.

Always follow standard workshop safety practices: use PPE, secure the workpiece, ensure compatible arbor and chuck, avoid overheating by allowing cooling breaks, and inspect the tool for wear before use. The tool is designed to meet typical industrial-use safety expectations through its sturdy bi-metal construction and heat-resistant teeth.

Yes. The bi-metal construction with HRC 65–68 steel teeth, heat-resistant design, and a durable alloy steel body are built to withstand frequent use and deliver clean cuts over time, offering solid long-term value for a range of materials.
