SATA GL53305 Bi-Metal Hole Saw 25mm

It’s suitable for wood, copper, aluminum, various metals, and stainless steel, delivering versatile performance across woodworking and light-metalworking tasks.

Bi-metal construction combines high-speed steel cutting teeth with a carbon steel body. This pairing delivers durable teeth for efficient cutting and a tough body for extended use, helping reduce wear and extend tool life when cutting across different materials.

Key specs include a 25 mm cutting diameter, bi-metal construction with HSS teeth (designed for high-speed cutting), high heat resistance, and compatibility with standard drill chucks. It’s designed for clean cuts with minimal burrs and reliable long-term performance.

Insert the hole saw into a compatible drill chuck and tighten securely. Align your pilot mark, start drilling at a low speed with light, steady pressure, and gradually increase as the cut progresses. For metal cutting, use appropriate lubrication or cutting fluid to manage heat and extend tooth life.

Common applications include plumbing, electrical installations, HVAC work, and cabinetry where precise 25 mm holes are needed in wood or metal materials.

Wear eye protection and gloves, secure the workpiece, and avoid excessive force that could cause the tool to bind or grab. Use appropriate speed settings for the material, keep hands clear of the cutting area, and let the tool cool if it heats up during use.

Keep the teeth clean and free of debris after use, wipe down the cutting surfaces, and store the tool in a dry place. For metal cutting, consider light lubrication to reduce heat and wear on the teeth during use.
