The DRYGRES 4DRILL range of diamond bits is recommended for drilling all types of ceramic tiles, especially porcelain tiles, and other facing materials such as marble and granite. In the DRYGRES 4DRILL range of drills, RUBI has used vacuum welding technology, VACUUM BRAZED, which increases resistance to temperature and friction, to fix the diamond particles to the cutting area. The DRYGRES 4DRILL bits are perfect for placing bathroom accessories or any type of decorative accessory on ceramic surfaces and/or natural stone.DRYGRES 4DRILL diamond bits have been designed to be used exclusively with a corded or cordless electric drill, always WITHOUT a hammer. Their hexagonal connection allows them to quickly adapt to .393 inches (10mm) head drills.
Drill depth for DRYGRES 4DRILL bits is 36mm. for 6, 8, and 10 mm diameters, and 40 mm deep for 12, 14, and 20 mm diameter drills. All DRYGRES 4DRILL bits contain wax inside. This wax melts during the use of the bit and facilitates the cooling and the evacuation of the remains of the drilling (If the wax runs out, the bit can continue working. Only the total loss of the diamond indicates the end of the life of the drill.).
As it is dry cutting, it is necessary, for proper cooling of the bit, to perform a slight and constant orbital movement during drilling, as well as to remove any remaining material, between drilling each time.
The DRYGRES 4DRILL bits, from RUBI, have a system that blocks the loss of this wax from the back of the bit, thus concentrating the wax, always at the tip and guaranteeing lubrication during drilling.
The minimum recommended speed of use for DRYGRES 4DRILL diamond drills is 1000 rpm. For a better finish and longer duration of the drill, it is important to respect the proper turning speed and perform a slight orbital movement while drilling, as well as making sure that once the hole is finished there are no remains of the drilled material inside the drill bit.

Just ok - too thick to apply evenly
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
Just ok - very thick, so difficult to apply evenly. I use this for outdoor cycling and it works, but it's so thick that it tends to clump instead of smoothly covering the skin.

Excellent mineral sunscreen for sensitive skin.
Size: 3 Fl Oz (Pack of 1), Set name: Tube - 3 oz.
I’ve been using the Blue Lizard Sensitive Mineral Sunscreen, and it’s become a staple in my routine. As someone with sensitive skin, I really appreciate that it’s fragrance-free and uses zinc oxide, providing great protection without causing any irritation or breakouts. It goes on smoothly, isn't overly greasy, and the water resistance holds up well for outdoor activities. The smart cap technology is a nice touch, too. Highly recommended if you’re looking for effective, non-irritating sun protection.

No chemicals that will be harmful!
Size: 5 Fl Oz (Pack of 2), Set name: Tube - 5 oz. 2-Pack
Ordered this mineral sunscreen looking for something simple and effective, and it’s been a solid option so far.
The zinc oxide formula is the main reason I went with it. It doesn’t rely on the same chemical ingredients found in a lot of other sunscreens, which is a big plus if you’re trying to avoid that. It feels like a cleaner option overall.
Coverage is good. It spreads evenly and holds up well, even with some water exposure. I’ve used it outdoors for extended periods, and it does its job without needing constant reapplication.
It does leave a slight white cast at first, which is pretty typical with mineral sunscreens, but it fades in as you rub it in. Not completely invisible, but manageable.
After a few uses, what stood out most is that it doesn’t have a strong smell and doesn’t irritate the skin. It just works without a lot of extras.
Compared to standard chemical sunscreens, this feels more straightforward and less harsh, especially for regular use.
For the price, it’s a great value. You’re getting strong sun protection without the added ingredients some people try to avoid.
If you’re looking for a mineral-based sunscreen that’s effective and a bit cleaner in formulation, this is a solid choice.

Great mineral sunscreen that actually works
Size: 5 Fl Oz (Pack of 1), Set name: Tube - 5 oz.
Blue Lizard Sensitive Mineral SPF 50 has become my daily go-to. It goes on smooth, doesn’t leave a weird white cast like some mineral sunscreens, and gives solid protection. I like that it’s 100% mineral with no harsh chemicals and has organic aloe vera in it, so my skin feels hydrated instead of dried out. No greasy feeling, no strong scent, and it holds up well even when I sweat a bit. Been using it for a few weeks now and it performs exactly how I want. Small bottle but a little goes a long way. Definitely recommend if you want a simple, effective mineral option.
