Name: DiamondEdge-300 Stone Engraving Machine
Brand: Impact Etching
Availability: InStock

The DiamondEdge-300 is a CNC Impact Etching stone engraving machine built specifically for the monument industry. It comes in three models so you can match the engraving field to the work you do — from small companion tablets and bronze-substitute plaques to full-size granite engraving machine jobs and large upright monuments. Every model uses the same diamond-tip Impact Etching technology, auto surface tracking, and included software; the difference between them is the maximum stone size each machine can engrave and its physical footprint in your shop.

Below are the exact specifications for each monument engraving machine in the lineup. Prices are listed on our stone engraving machine pricing & ROI page, and a full technology overview is on the DiamondEdge-300 details page.

Which stone engraving machine size is right for your shop?

Choosing between the three DiamondEdge-300 models comes down to the largest stone you need to engrave in a single pass and the space you have available:

DiamondEdge-Sprinter-300 — the compact granite engraving machine. Its 15.7" × 23.6" field handles companion tablets, flat markers, bronze-replacement plaques, and pet memorials, and its 36" × 30" footprint fits shops where bench space is tight. It is the most affordable way to bring Impact Etching in-house.
DiamondEdge-Max-300 — the model most monument builders choose. The 55.1" × 27.6" field covers the large majority of upright headstones, portraits, and scenes without repositioning the stone, while the machine still fits a standard production bay.
DiamondEdge-SuperMax-300 — the largest-capacity monument engraving machine, with a 63.0" × 39.4" field for oversize uprights, benches, and high-volume production where you want to load the biggest stones and keep throughput high.

Features shared across every DiamondEdge-300 machine

Diamond-tip Impact Etching — physically strikes the stone for bright, deep, permanent engravings on granite and marble, with no burning or paint required.
Auto surface tracking — the tracking head follows the stone automatically, so there is no focusing or leveling to set up before each job.
3× faster than our original Granite™ model, our 3rd-generation impact etcher improves throughput without sacrificing quality.

All software included — no separate purchases such as PhotoGrav or LightBurn; optional pre-configured laptop available at cost.
Instant start — begins etching immediately, with none of the warm-ups or test passes a laser needs.
Free training & support — one-on-one training is included, with phone and email support available including nights and weekends. See ease of use & training.
