Bihui Drilling Jig with a Suction Cup

BIHUI metal drilling jig with a suction cup, adjustable. Made to hold the bit steady while you drill holes. The suction cup grips the jig firmly and lets you do the job single-handed. The clamping plane sits above the diamond layer, so the jig itself does not get damaged.
The adjustable jig is made of galvanised steel and high-grade plastic. The adjustable core bit guide sits on a ∅125 mm suction cup. The jig has a built-in water port that connects to the cooling system for wet drilling. The core bit guide arrangement covers hole diameters from 4 mm to 115 mm. Fixed template hole sizes are ∅4,5,6,7,8,10,12,20,35 mm. The template suits glossy surfaces of tile, glass, marble and granite.
