Zenesis Z-Thin Wall Core Bit – 1 in., 5/8 in.-11, Wet Only
Zenesis Z-Thin Wall Core Bit – 1 in., 5/8 in.-11, Wet Only
The Zenesis Z-Thin Wall Core Bit is a 1 in. thin wall diamond core bit with a 5/8 in.-11 thread for drilling clean holes in porcelain, sintered stone, granite, engineered stone and marble on an angle grinder. Zenesis specifies wet use only, a continuous thin rim with a 9.5 mm segment, and wrench flats for removal.
This is sized for small faucet, fixture and anchor holes. The same line is stocked here in 3/4, 1, 1-1/4, 1-3/8, 1-1/2, 1-3/4, 2 and 4 in. Wet use only: run cooling water throughout the cut. For a dry-or-wet bit on natural stone and porcelain, use a brazed core bit instead.

Frequently Asked Questions
What diameter and thread is this bit?
1 in. diameter on a 5/8 in.-11 thread, which fits a standard angle grinder spindle.
Can it be used dry?
No. Zenesis specifies wet use only. Keep cooling water on the bit for the whole cut.
What materials does it drill?
Porcelain, sintered stone, granite, engineered stone, marble, travertine and glass; the manufacturer lists it as approved for Dekton.
Why a thin wall?
A thinner continuous rim removes less material, so it cuts faster and leaves less chipping and blow-out on the underside than a standard segmented core bit.
How deep will it drill?
The manufacturer does not publish a drilling depth or a max RPM for this line; stay inside your grinder's rating.
