ريشة منشار ثقب ثنائي المعدن قياس (35mm) موديل (GL53308)

It’s designed to cut wood, copper, aluminum, various metals, and stainless steel, making it versatile for woodworking, metalworking, and construction tasks.

Bi-metal construction combines a high-speed steel cutting edge with a tough alloy steel body. This provides long-lasting sharpness, improved durability, heat resistance, and the ability to maintain cutting efficiency under heavier work loads.

Key specs include a 35mm diameter, high-speed steel teeth rated for cutting, a durable alloy steel body, heat-resistant teeth, and compatibility with standard drills and arbors. It’s designed for clean, burr-free holes with minimal effort.

Use with a compatible arbor and standard drill. A pilot hole is often helpful to guide the hole saw and prevent wandering. Ensure your arbor size matches your drill and the hole saw’s shank is compatible with your chuck.

Attach the hole saw to a compatible arbor, insert into a drill, and secure firmly. Begin drilling at a lower speed to establish a guide, then increase speed gradually. Apply steady pressure, avoid forcing the tool, and keep the workpiece clamped and supported for clean cuts.

Wear eye protection and gloves, clamp the workpiece securely, and avoid overheating by using light, steady pressure and occasional backing off to clear chips. Use wood backing or a scrap piece beneath the cutting area to prevent tear-out, and never cut through knots or extremely hard materials without appropriate preparation.

35mm holes are common for passing smaller conduit, wiring, plumbing lines, or cable glands, as well as creating access points in wooden or metal panels during electrical, HVAC, or mechanical installations.

If you need slightly smaller or larger holes, consider these SATA options from the same line: 32mm (GL53306) and 40mm (GL53310). They offer similar bi-metal construction and durability with the corresponding diameter differences.

The bi-metal design with a high-speed steel edge helps maintain sharpness and resist wear when cutting metals, including stainless steel, while still delivering efficient cuts in wood. For best results with metal, use steady feed rate and lubricant to reduce heat buildup.

Keep teeth clean and free of built-up material, avoid overheating by using moderate speeds and steady pressure, occasionally oil the cutting edge to reduce friction, and store the tool in a dry place to prevent corrosion. Inspect the teeth for wear and replace if any significant damage is visible.
