قاعدة رؤوس القص و التفريغ الدائري (Bosch A2) قياس (14mm-30)

The Bosch Arbor Bit A2 14-30mm is an arbour attachment designed to work with 14–30 mm hole saws. It enables precise, stable drilling in wood, metal, and plastic, and features a quick-change mechanism for easy bit replacement and a secure grip to minimize wobble during cutting.

This arbor bit is suitable for drilling in wood (softwood and hardwood), plastics, and metals when used with the corresponding hole saws. The construction is heat-treated steel for durability in demanding tasks.

Diameter range: 14–30 mm. Construction: high-quality, heat-treated steel for long life. Attachment: quick-change, secure blade attachment for efficient cutting. Compatibility: designed to work with Bosch drills and 14–30 mm hole saws.

Ensure your drill is powered off. Release the quick-change mechanism, align the arbor with the drill’s chuck or adapter, and securely tighten. To replace, release the mechanism again, remove the current bit, and attach the new 14–30 mm hole saw assembly, then tighten firmly.

Ideal for professional and DIY projects that require precise holes in wood (softwood/hardwood/plywood), and for drilling through plastics and metals when used with the appropriate 14–30 mm hole saws. It’s well-suited for cabinetry, furniture making, and other precision drilling tasks.

Wear eye protection and gloves, secure the workpiece with clamps, ensure the arbor and hole saw are properly attached, avoid excessive force or binding, use appropriate speeds for the material, and unplug the drill when changing bits.

The A2 14-30mm offers a larger working diameter range (14–30 mm) for bigger holes, while the A1 10-20mm covers smaller holes. The A2 design emphasizes quick-change attachment and stability for larger cuts, whereas the A1 is optimized for smaller-diameter holes.

If you’re exploring alternatives on Fepy, you might also look at: Bosch Hole Saw Arbor 14-30mm — https://www.fepy.com/product/bosch-hole-saw-arbor-14-30mm and DeWalt Arbor Bit 12-20mm — https://www.fepy.com/product/dewalt-arbor-bit-12-20mm. These can be used with compatible hole saws and offer similar quick-change features for different hole sizes.

Keep the arbor clean and dry when not in use, wipe off debris after drilling, inspect for wear or damage before each use, and avoid exposing the steel to moisture for extended periods. Store in a dry place and use the correct size hole saws to prevent undue stress on the arbor.

When drilling wood, expect smoother cuts and clean hole edges with proper support and slower feeds. For metal, use appropriate lubrication and slower speeds to minimize heat and wear. The heat-treated steel construction helps durability across both materials, but material-specific techniques will yield the best results.

Yes. Its heavy-duty construction, secure grip, and quick-change mechanism are designed to support both DIY tasks and professional workloads, providing precision and efficiency across a range of materials.

Yes. Use only compatible 14–30 mm hole saws with the arbor, avoid overtightening, ensure the quick-change mechanism is fully engaged, and confirm stability before starting. Always verify drill compatibility and material suitability for a safe, accurate cut.
