About KDRILLS Drain Groove Tools
Drain grooves are the shallow channels cut into a countertop beside the sink so water runs back to the bowl. KDRILLS makes two kinds of tool for them on CNC work centers: routers and wheels.
The Drain Groove Routers are listed on the product page in diameters of 6, 8, 10, 12, 14, 16, 18 and 20 mm; the data sheet lists sets at 10, 15 and 20 mm, each with three positions, 1E, 2N and 3Q, and each position has its own radius. For the 10 mm router the radii are 4.5, 4.7 and 5 mm. The standard set is three positions with different diamond grits and one rubber polishing router.
The Drain Groove Wheels (series KGG) are listed in diameters of 100, 140 and 180 mm, with radii of 5, 7 and 10 mm. The data sheet groups them by the machine they mount on, including hand machines. The set is one diamond wheel and one polishing wheel in different grits. The product page describes the range as usable on marbles, granites and synthetic materials; the data sheet lists marble and granite.
Tell us the groove radius you cut, the machine and the material, through the contact page or [email protected], and we will match the set.
