With a very high diamond concentration, the Core Bore Thinwall Premium Black P38Z Core Bit gives great drilling speed in all types of wet drilling applications. Thin gauge barrel and segments have less resistance when drilling, making them great for handheld drilling applications (they can be used on a rig but you will need the correct adapter). The diamonds used in these bits are of the highest quality providing faster cutting in concrete with high steel applications. Also effective in hard materials like refractory(firebrick), granite, bluestone, and other natural stones.
Use wet only.
Core Travel: 12" for bits up between 1/2" to 7/8" in diameter, 13" core travel for bits 1" and larger.
All Thinwall bits have a 5/8"-11 hub.
