Diamond Drill Bits, Scoring Wheels, and Professional Accessories

Mondrillo uses a specially formulated Performer coolant fluid applied to the drill bit before and during use. This fluid lubricates the cutting interface and dissipates heat without the mess of water. The bit design incorporates aggressive diamond segments that cut efficiently at lower temperatures. This combination lets you drill porcelain on installed walls without protecting surrounding areas from water spray.

FSB (Fast Smooth Boring) diamond core bits are optimized for larger hole diameters and faster cutting through thick materials. FAJ diamond drill bits handle smaller holes and precision work where edge quality matters most. Both use diamond particles in a matrix bond, but segment geometry and particle concentration differ based on intended application.

Watch for these signs: visible flat spots on the wheel edge, inconsistent scoring depth requiring multiple passes, increased pressure needed to create incision, or irregular break patterns on tiles that previously cut cleanly. Most wheels show wear visually before performance drops significantly. Keeping spare wheels on hand prevents job delays when replacement becomes necessary.

Montolit designs wheels specifically for their cutter geometry and bearing systems. While some wheels may physically fit other brands, performance will not match original specifications. The titanium coating, carbide composition, and edge angle are engineered for Masterpiuma rail and pressure systems. Using OEM wheels ensures the quality that Montolit tools are known for.

Diamond blade segments can glaze over - the metal bond covering exposed diamond particles and reducing cutting action. A dressing tool contains abrasive material that wears away this glaze, exposing fresh diamonds. Make several cuts through the dressing tool with your blade, applying light pressure. Cutting speed typically returns to near-new levels after proper dressing.

Standard wet drilling uses clean water as coolant - it dissipates heat and flushes debris from the cut. For best results, maintain steady water flow to the bit during operation. Some contractors add small amounts of cutting oil to the water for dense materials, though plain water works for most porcelain and ceramic applications.

Drilling porcelain without water seemed impossible - the material is hard enough to destroy conventional bits instantly without cooling. Montolit engineering worked through multiple approaches before achieving reliable dry drilling. The result addresses a real job site need: making holes in tiles already installed on walls without water damage to surrounding areas or the hassle of containment systems.

We maintain inventory of common replacement parts including scoring wheels, breaking pads, and wear components for current and recent Masterpiuma models. For older or less common models, we can order specific parts through Montolit distribution channels. Contact us with your model number to check availability and lead times.

Glass tiles require FAV Type diamond drill bits specifically designed for water drilling of glass. Never attempt to drill glass dry - the heat will crack the tile instantly. Use steady water flow, moderate speed, and light pressure. The FAV bit geometry prevents the grabbing and chipping that occurs with standard porcelain bits on glass material.

FPU universal milling bits are designed specifically for enlarging existing holes. Unlike core bits that need a solid center to start, FPU bits can expand a hole from its existing edge. Use water cooling and work gradually around the circumference rather than forcing through. This technique is essential for retrofit work where initial holes are undersized.

FPS countersink tools create chamfered (beveled) edges around drilled holes, removing the sharp edge left by core bits. This chamfer provides a professional finish, prevents edge chipping during fixture installation, and allows countersunk screw heads to sit flush. Essential for visible holes in backsplashes and feature walls.
