Bosch CWX1M450 4.5in Masonry Cutting Wheel X-lock 24 Grit 25pk

Product Description

The ROBERT BOSCH TOOL GROUP CWX1M450 is a Type 1A (ISO 41) abrasive cutting wheel engineered for masonry applications on small angle grinders. Measuring 4.5 inches in diameter with a 1/16-inch kerf width, it uses a silicon carbide grit bond rated at 24 grit for aggressive, fast material removal. The wheel mounts via an X-Lock arbor system, which snaps on and engages a wheel-release lever on compatible grinders for change-out reported to be up to 5 times faster than conventional flange-nut mounting. Resinoid bonding with multiple layers of stranded fiberglass reinforcement supports speed and durability under sustained cutting load. Precision-balanced manufacturing reduces vibration and improves working speed during operation.

This wheel is designed for masonry cutting tasks in residential and commercial construction, renovation, and maintenance applications. It is intended for use with small angle grinders equipped with an X-Lock arbor or a standard 7/8-inch arbor mount. Backward compatibility with 7/8-inch arbor mounts makes it usable on a broad range of existing angle grinder inventory. Color-coding on the wheel identifies the application type, supporting fast selection on the job site. The 25-unit pack suits contractors and trades workers with ongoing masonry cutting demands.

Key Features

• Type 1A (ISO 41) abrasive cutting wheel, 4.5 inches diameter by 1/16-inch width, 24 grit silicon carbide
• X-Lock snap-on mounting with wheel-release lever for tool-free change-out up to 5 times faster than spanner-wrench systems
• No flange nuts or spanner wrench required, eliminating small parts that can be lost in the field
• Backward compatible with standard 7/8-inch arbor mounts for use on non-X-Lock grinders
• Resinoid bond with multiple layers of stranded fiberglass reinforcement for durability under cutting loads
• Precision-balanced construction reduces vibration and supports consistent working speed

Compatibility

Designed for use with small angle grinders equipped with an X-Lock arbor system. Also backward compatible with standard 7/8-inch arbor mounts for use on conventional angle grinders.

Installation Notes

Installation and wheel changes should be performed by qualified operators following the grinder manufacturer guidelines and applicable ANSI B7.1 safe-use requirements for abrasive wheels. Disconnect power or remove the battery from the grinder before mounting or removing any abrasive wheel. Inspect the wheel for cracks or damage before each use and never mount a damaged wheel. Always verify the grinder RPM rating meets or exceeds the maximum rated speed marked on the wheel.
