ريشة التفريغ بوش ثنائية المعدن مقاس (19mm) من الفولاذ عالي السرعة (HSS) موديل (2609255600)

Core specs include a 19 mm cutting diameter, 44 mm maximum cutting depth, HSS bi-metal construction for durability, 1/4" hex shank compatibility, and a multi-material capability that handles wood, plastic, non-ferrous metals, acrylics, and metal sheets. It also features a compact, lightweight design and heat-resistant edge teeth to maintain sharpness during use.

It’s suitable for wood, plastic, aluminum (alloyed and non-alloyed), non-ferrous metals, cast steel, cast iron, acrylic glass, and similar materials. Cutting speeds and chip clearance will be more aggressive on softer materials like wood and plastic, while metal and acrylic require careful feed control and steady pressure to avoid heat buildup and tooth wear.

The integrated blade and center pilot drill reduce vibration, improve concentricity, and stabilize the cut. This design minimizes walking, helps maintain accuracy in overhead or tight-space drilling, and speeds up setup and changeovers during multi-hole tasks.

Use a drill or drill driver with a compatible chuck, ideally a 1/4" hex shank, and ensure the workpiece is secured. Start with the pilot drill engaged to guide the holesaw, apply steady pressure without forcing, and maintain consistent speed appropriate for the material. Lubrication is beneficial when cutting metal, and avoid overheating by allowing cooling pauses on longer cuts.

Use appropriate speeds for the material (lower speeds for metal, higher speeds for wood/plastic), maintain a steady feed rate, and ensure chips have a clear path off the teeth. The optimized tooth geometry helps with chip removal, and the heat-resistant edge teeth maintain sharpness longer under typical high-speed drilling.

Wear eye protection and hearing protection, clamp the workpiece securely, keep hands away from the rotating teeth, and avoid working with damaged tools. Use a stable drill press or secure handheld setup, and unplug or remove power before changing accessories.

The HSS bi-metal construction is designed for extended durability under heat and pressure. Replace the teeth if you notice significant tooth wear, loss of straightness, or if cutting efficiency drops noticeably. Regular inspection after heavy use ensures consistent performance.
