Montolit FPU 20mm Diamond Milling Bit

FPU is a versatile milling bit designed to enlarge, shape and/or round bevel existing holes in Porcelain, Hard Ceramic, Granite and Marble.

FPU is also suitable to easily create round side indentation necessary to accommodate pipes or electric wire lines.

This is a save money tool because with just one standard core bit + one FPU you are able to create many different hole sizes, without needing to buy several different core bits.

FPU is manufactured with top quality raw materials and high end production processes to grant outstanding performances.

It can be used with any standard grinder.

No adapters needed.

Recommended for Tile Setters, General Contractors, Plumbers and Electricians.

Attention! FPU isn’t designed to make holes. FPU is designed to shape and enlarge existing holes.
