Common Questions
Frequently Asked Questions
What materials can the Alpha Vortex for Marble cut?
The blade is designed for marble, limestone, and other softer stone materials. Alpha specifically warns against using the marble version on granite because the electroplated diamonds can round over or dull quickly on harder materials, causing the blade to lose its cutting ability.
What cutting applications is the Vortex blade designed for?
Alpha designed the blade for flush cutting, 90-degree inside corners, and curved shapes. Its thin profile and protected sides support intricate fabrication where a conventional straight-cut blade may not provide the required access or control. It is suitable for professional shop and field fabrication.
Does the blade require a Quad adapter?
Yes. The blade uses a 20mm Quad Drive and requires a compatible Quad adapter for installation on a high-speed angle grinder. Alpha states that the blade should not be mounted directly to the tool flange because of the countersunk holes in its core.
Is a Quad adapter included with the blade?
Part number FCM50AH identifies the 5" Vortex blade. Alpha lists the BAH-5/8 brass adapter and AAH-20 aluminum adapter under separate part numbers, so confirm the selected package contents before ordering. Both listed adapters use a 5/8"-11 threaded connection.
Can the blade be used on a polishing tool?
No. Use the blade on a high-speed angle grinder rated for a 5" blade and no more than 12,200 RPM, together with the required Quad adapter. Alpha does not recommend using it on a polishing tool because polishers operate too slowly for the blade.
Can the Alpha Vortex Flush Cutting Blade be used wet or dry?
Yes. Alpha permits the Vortex blade to be used wet or dry. The manufacturer notes that wet cutting generally increases blade life and helps keep silica dust out of the air, provided the tool and work setup safely support wet operation.
What is the maximum operating speed?
The 5" blade has a maximum operating speed of 12,200 RPM. The grinder's no-load speed must not exceed this rating, and the machine must be approved for the blade diameter, Quad adapter, and intended cutting method before use.
How does the blade support clean, durable cutting?
The advanced electroplated bond is developed for smooth cutting in softer natural stone. Dual side-protection segments strengthen the blade during flush and intricate work, helping it resist damage while supporting clean cuts in demanding marble and limestone fabrication applications.
