The Hardest Substance

DR4E Technology

Combining oversize traditional head shapes and cutting edge technology, the DR4E driver has the hottest and hardest face in golf.

With our recent breakthrough in metallurgy and clubhead design, Diamond Touch has developed a way to marry the best performance and the hardest face. The face is made of a vacuum brazed industrial strength diamond that is 10 times harder than Titanium, giving you explosive distance from the tee and fairway.

Independent testing showed that Diamond Touch DR4E driver to be longer and straighter than the most popular clubs on the market today. The results speak for themselves, the robot doesn’t lie.

HARDNESS

Diamond Touch: 6000-10000kg/mm2
Titanium Alloy: 200-500kg/mm2
Stainless Steel: 200-500kg/mm2

(Knopp Method)

If you look at these numbers, it is clear that even if you take hardest values from the Titanium and Stainless Steel alloys and compare them to the Diamond Touch values, Diamond Touch is at least 10 and as much as 20 times harder than the hardest Titanium or Steel alloys.
