45-Degree Cutting: When It’s Essential and What Machinery You Need

When working with marble, granite, or sintered stone slabs, one technique stands out for its precision and elegance: the 45-degree cut.

Also known as the Jolly cut, this process involves beveling the edges of slabs at a 45° angle rather than the standard vertical cut. While it may sound straightforward, in practice it’s a highly intricate operation—especially on high-value materials. So, why is it so important?

Why Use a 45-Degree Cut?

The 45-degree cut allows two slabs to be joined seamlessly at a perfect 90° corner, producing a smooth, continuous finish without visible joints or bulky metal trims. This is critical in applications like:

• Countertops and kitchen islands

• Wall cladding and decorative panels

• Stairs and step edges

Compared to using metal profiles to join pieces, the 45-degree cut results in a far more refined and seamless look. For premium surfaces and luxury interior applications, this finish is not just preferred—it’s expected.

However, achieving this level of precision—especially on large, fragile stone slabs—requires advanced cutting machinery.

What Kind of Machinery is Suitable for 45-Degree Cuts?

Without the right equipment, consistent and accurate 45° beveling is nearly impossible. Let’s explore the types of machinery that can handle the challenge:

  1. Portable Bridge Saws (for Job Sites & Lightweight Materials)

Portable bridge saws allow the entire cutting head or bridge to tilt to 45°, enabling bevel cuts on tiles, thin marble, bricks, and ceramics. These are ideal for on-site jobs or lighter-duty projects.

  2. Fixed Bridge Saws (Professional Workshops)

Fixed bridge saws provide high rigidity and stability, essential for precise 45° beveling on thicker materials like granite. These machines tilt the entire bridge—not just the motor—which ensures more consistent depth and angle across long cuts.

  3. CNC Bridge Saws (Automated Precision)

Numerical control (CNC) bridge saws offer the ultimate in precision and automation. With programmable tilt angles and multi-axis interpolation, they’re capable of complex bevel cuts and repeated operations, even on uncalibrated or irregular slabs.
