Grog brings back the steel-tip marker Metal Head legend—this is the empty version of the Driller™ 04 RSP.

Designed with a Squeezer®-style body for real flow control and paired with a scratchproof, extra wear-resistant 4 mm Steelball™ tip. This marker is built to work on almost any surface, where other marker tips fail.

What is the Grog Driller 04 EPT?

It's the empty version of the Driller 04 RSP. It features the same soft body and ultra-tough 4 mm Steelball™ tip, but leaves the filling choice up to your experimentation.

What ink or paint should I use in the Driller EPT?

It's made for testing. Grog recommends Ruff Stuff Paint™ (via the Buckshot system) to get the most out of the steel tip, but you can experiment with your own high-density custom mixes.

Can I use very fluid inks in the Driller EPT?

Technically yes, but be careful: the Steelball™ tip is engineered for thick paints. Very runny inks (like standard alcohol dyes) might flow too fast or leak.

Is the Driller EPT compatible with the Buckshot system?

Yes. The head of the Driller EPT (the tip unit) is identical to the filled model, so you can screw it onto any Buckshot body to turn it into a working marker.
