DRM-300 Vertical Drilling Machine

1. Machine Overview

The DRM-300 is a vertical-spindle drilling machine built for deep, accurate holes in tombstones, address stones, lantern blanks and craft blocks.
With Ø300 mm max bit, 700 mm lift and 7.5 kW direct motor, it drills straight, chip-free holes 10× faster than hand-held units—ideal for single-piece or small-batch stone workshops.

Why DRM-300?
