How to Cut and Drill 20mm Porcelain Pavers: What Contractors and Homeowners Should Know
A plain-English guide to cutting and drilling thick porcelain pavers: wet saw use, porcelain-rated blades, water cooling, and edge quality.
Cutting 20mm porcelain pavers is not the same as cutting standard wall tile. The material is thicker, harder, and less forgiving when the wrong blade, tool pressure, or drilling method is used. This guide helps customers understand why experienced installers and the right equipment matter.
Why the right blade matters
Thick porcelain can quickly ruin poor-quality blades. A blade that works for thinner tile may struggle with 20mm pavers, create rough edges, slow down the installer, or increase breakage risk. This is especially important when cut edges will remain visible near pool coping, drains, steps, or borders.
Wet cutting should be controlled, not forced
The goal is a steady cut using water and the right blade, not aggressive pressure. For visible cuts, the installer may also need to dress or soften the edge after cutting so the finished project looks intentional.
Drilling holes is a specialty operation
When holes are needed for drains, lighting, anchors, or other details, the paver should be supported on a rigid vibration-absorbing surface. The drill should not be in hammer mode, and the core bit is typically started at a slight angle before using a gentle oscillating movement.
Safety should be visible on the jobsite
Cutting and drilling porcelain creates dust and sharp edges. Wet or suction tools, eye protection, gloves, masks, and steel toe shoes should be part of the work plan.
Common questions
Can a standard tile saw cut 20mm porcelain pavers?
It depends on the saw capacity, blade quality, water delivery, and experience of the installer. Many standard tile tools are not ideal for thick outdoor porcelain pavers.
Why do porcelain pavers break during cutting?
Common reasons include poor blade quality, excessive force, cutting vertically into the surface, insufficient water, vibration, or unsupported material.
