Robert Bosch Tool Group DBX4543S Diamond Blade 4.5 in

Product Description

The ROBERT BOSCH TOOL GROUP DBX4543S is a 4.5-inch continuous rim diamond blade engineered for clean, chip-free cuts in tile, stone, and masonry materials. This blade features the X-Lock mounting system, which allows snap-on wheel attachment and a grinder-side wheel release lever for wheel changes that are up to 5 times faster than standard arbor-mount setups. The optimized diamond mix is formulated to balance cutting speed with extended blade life. Each package includes 5 blades, making it a practical stocking option for active job sites.

This blade is suited for use with angle grinders equipped with either X-Lock or 7/8-inch arbor mounts, covering a wide range of grinder makes commonly found in tile-setting, masonry, and general construction trades. Typical applications include straight and curved cuts in ceramic tile, porcelain, natural stone, and similar hard materials in both residential and light commercial settings. The continuous rim profile delivers smooth cut edges with minimal chipping, which is important for finished-surface work.

Key Features

• X-Lock mounting system enables snap-on installation and lever-actuated release for fast wheel changes
• Compatible with 7/8-inch arbor mounts for use on standard angle grinders without X-Lock
• Continuous rim diamond profile produces smooth, low-chip cuts in tile and stone

Compatibility

Compatible with angle grinders accepting X-Lock mounting or 7/8-inch arbor mounts. Designed as a direct-fit replacement or supplemental blade for grinders supporting either of those mount standards.

Installation Notes

Blade installation and removal must be performed with the grinder unplugged or the battery removed. X-Lock blades snap onto the spindle and are released via the lever on the grinder body — no wrench is required for X-Lock-equipped tools. When using the 7/8-inch arbor adapter, follow the grinder manufacturer's torque and clamping instructions. Always verify blade condition before use and wear appropriate eye and face protection per ANSI B7.1 and tool manufacturer guidelines.
