Bosch CWX27M450 4.5 in 30 Grit Metal Cutting Wheel 25 Pack

Product Description

The ROBERT BOSCH TOOL GROUP CWX27M450 is a Type 27A ISO 42 bonded abrasive cutting and grinding wheel engineered for metal removal with small angle grinders. Measuring 4.5 inches in diameter and 0.098 inches thick, it uses fixed-mount high-quality aluminum oxide grit at 30 grit for aggressive stock removal. The X-Lock arbor interface snaps on without a wrench, and the wheel also fits standard 7/8-inch arbor mounts. Precision manufacturing tolerances reduce vibration during operation, supporting improved working speed and consistent cut quality. This wheel is sold in a 25-pack, making it practical for shops and service crews running high wheel consumption.

The CWX27M450 is designed for metal cutting and grinding applications where fast material removal is the priority. It fits small angle grinders equipped with either X-Lock arbor systems or standard 7/8-inch arbor adapters. The 30-grit aluminum oxide bond is well suited to ferrous metals and general fabrication work. A color-coding system helps techs and operators quickly identify the correct wheel for the application, reducing setup errors on multi-wheel job sites. Suitable for residential and commercial metalwork, HVAC sheet metal, structural steel prep, and general maintenance grinding tasks.

Installation Notes

Mount and service abrasive wheels only when the grinder is fully powered down and unplugged or locked out per applicable safety procedures. Inspect each wheel for cracks or chips before mounting — do not use a damaged wheel. X-Lock wheels snap on without a backing flange or separate wrench; confirm positive engagement before powering on. Always operate with the appropriate guard in place and wear face and eye protection per ANSI B7.1 and applicable jobsite PPE requirements.
