Alpha Contour for Granite/Engineered Stone
Alpha Contour for Granite/Engineered Stone is specially engineered for precision curve cutting, making it the ultimate solution for granite sinkholes, engineered stone, and even harder types of marble. Its unique design features direct sintered diamond segments on both sides of the steel core as well as on the peripheral cutting edge. This advanced construction ensures clean, accurate, and safe curved cuts while creating a wider kerf that enhances maneuverability and makes cutting easier.
The inner diamond segment protects the steel core from undercutting—a common issue in curve cutting—while the wider kerf eliminates the need for difficult and time-consuming plunge cuts. Versatile and efficient, the Alpha Contour can be used wet or dry and fits most common angle grinders. With its excellent cutting performance, durability, and cost-effectiveness, the Alpha Contour is the professional’s top choice for any curved cutting application.

Frequently Asked Questions
What materials can be cut using the Alpha® Contour for Granite/Engineered Stone?
This blade is designed for cutting all types of granites and all brands of engineered stone.
The Alpha® Contour for Granite/Engineered Stone is a dry cutting blade, can I use this blade for wet application?
Yes. Alpha® highly recommends using this blade for wet cutting together with our AWS-125 Wet Stone Cutter. Wet cutting will generally increase blade life and will keep harmful dust (Silica) out of the air.
What sizes are available for the Alpha® Contour for Granite/Engineered Stone blade?
The blades are available in 4”, 4-1/2”, 5” and 6” diameters.
Which diameter should I choose to cut 1-1/4” slabs?
The 4” and 4-1/2” diameter blades are designed to cut 3/4" slabs and the 5” diameter to cut 1-1/4” slabs.
What is the 6” blade used for?
This blade is intended to be used on CNC machinery which have cutting heads; however; you can also use the 6” diameter blade on 6” and 7” angle grinders.
Can I use the Alpha® Contour for Granite/Engineered Stone for cutting Marble or Porcelain slab material?
No. The Contour for Granite/Engineered Stone blade is only intended for use on the material for which was designed. Using this blade for cutting marble or porcelain slab material may result in a shorter life or chipping on the material.
