Alpha Quad Blades
Alpha Quad Blades combine the exceptional performance of the Alpha® Plus diamond blade with a unique design for flush cutting applications. Compatible with the exclusive Quad Drive Adapter, these blades eliminate the need for a lock nut, allowing a threaded arbor connection for angle grinders in “flush cutting” mode. The Quad Drive Adapter also accommodates larger diameters, enabling use with the grinder’s safety guard in place. Perfect for fabricators making precise 90° inside corners, monument builders cleaning up large saw cut marks, and contractors converting their angle grinder into a versatile cutting tool on-site. Sculptors also appreciate Alpha Quad’s ability to reach tight corners and hard-to-access areas. Offering unmatched performance for specialized applications, Alpha Quad Blades deliver precision, safety, and versatility in one exceptional cutting solution.

Frequently Asked Questions
What applications are the Alpha® Quad blades designed for?
The Alpha® Quad blades are designed for flush cutting and making 90 degree inside corners.
Can I use the Alpha® Quad blade for groove cutting application?
No. We recommend using the Alpha® Groove Cutter together with the Alpha® Universal Safety Guard Kit for groove cutting application.
Can I use the Alpha® Quad blade without the BAH or FAH adapters?
No. The Alpha® Quad blade must always be used together with the BAH or FAH adapters. Alpha® does not recommend mounting the Quad blade directly onto the flange of a power tool without the BAH or FAH adapter due to the countersunk holes drilled within the core of the blade.
