About This Product
Zero-Tolerance Grinding for 90-Degree Edges
Alpha® Profiler Z-Series Vertical Diamond Grinding Wheels provide aggressive wet grinding for shaping straight 90-degree edges on granite, engineered quartz, concrete, and porcelain. Also known as zero-tolerance or drum grinding wheels, the series is available in 1-1/4" (3cm), 1-1/2" (4cm), and 2" (5cm) sizes.
Vacuum-Brazed Shape Retention
Vacuum-brazed diamonds provide aggressive grinding action, long service life, and lasting profile shape. Unlike grinding wheels that gradually distort as their bond wears, the Z-Series is designed to retain its straight profile and support consistent vertical edge grinding throughout its service life.
Guided Wet Grinding
A nylon guide helps prevent the Profiler from dipping, while the rotary toucher controls grinding depth to maintain a straight finished edge. Each diamond grinder wheel has a 5/8"-11 female thread and internal water passage holes for compatible center water-feed polishers. The PFZ301 and PFZ401 are rated for 3,500 RPM, while the PFZ501 is rated for 6,000 RPM.
Sink Cutouts and Exterior Corners
The Profiler Z-Series can refine the curved surface left after cutting a sink opening with an Alpha Contour Blade and compatible stone cutter, creating a straight 90-degree edge for the finished opening. Alpha also recommends pairing the Vertical Grinding Wheel with a Corner Ruler when producing uniform straight or rounded exterior corners.

Common Questions
Frequently Asked Questions
What is the Alpha Profiler Z-Series used for?
The Z-Series performs vertical or zero-tolerance grinding to create and refine straight 90-degree edges during stone, quartz, concrete, and porcelain fabrication.
What materials can the Profiler Z-Series grind?
The wheels are recommended for granite, quartz and engineered stone, concrete, and porcelain. Concrete can be ground, but its abrasive nature may substantially shorten wheel life.
What Profiler Z-Series sizes are available?
The PFZ301 measures 1-1/4" and is recommended for 2cm and 3cm materials. The PFZ401 measures 1-1/2" for 4cm material, while the PFZ501 measures 2" for 5cm material.
What is the maximum RPM for each Profiler Z-Series wheel?
The 1-1/4" PFZ301 and 1-1/2" PFZ401 have a maximum speed of 3,500 RPM. The 2" PFZ501 has a maximum speed of 6,000 RPM.
Is the Profiler Z-Series used wet or dry?
Alpha Profilers are for wet use only. The Z-Series has internal water passage holes and must be used with a compatible center water-feed polisher.
How does the Profiler Z-Series maintain a consistent vertical edge?
The vacuum-brazed wheel retains its straight profile, while the rotary toucher controls grinding depth and the nylon guide helps prevent dipping.
Can the Profiler Z-Series be used for sink cutouts?
Yes. The Z-Series can remove the curved material left after a sink opening is cut and refine the opening into a straight 90-degree vertical surface.
Can the Profiler Z-Series be used on a high-speed grinder?
No. Alpha Profilers require compatible low-RPM center water-feed polishers and should not be used on high-speed grinders or with an external water-feed system.
