MARSBASE Diamond Core Drill Bits Kit — 10-Piece Serrated Tile Drill Bits with EVA Guide Jig

Overview

The MARSBASE Diamond Core Drill Bits Kit is a 10-piece set built for precision and versatility across ceramic, glass, tile, and stone projects. Each bit is engineered for stable starts, clean holes, and reliable performance in everyday tasks, whether you’re upgrading a backsplash or installing fixtures.

Key benefits

• Durable brazed diamond design with a corrosion-resistant surface and a thick diamond coating for strong, long-lasting cutting edges.
• Fast, smooth drilling thanks to serrated top teeth and neat tooth openings that minimize dust buildup and improve efficiency.
• Dry and wet versatility supports use without coolant or with water to extend tool life when needed.

With 10 hole saw sizes ranging from 6 mm to 50 mm and a EVA mold precise positioner plus a hard storage bag, this kit is ready for diverse projects. It’s designed to work with ceramic tiles, ceramics, glass (non-tempered), marble, granite, terrazzo, plastic, thin wood, and gypsum board, offering dependable performance across materials.

In real-world use, the kit can help you start holes cleanly in a tiled wall, create glass panel openings, or cut precise holes in stone countertops. The serrated design promotes speed, while the dust removal grooves help keep the drilling area clearer, which can improve visibility and control during the job. The EVA guide jig keeps the bit aligned, reducing the risk of slips and misaligned holes.

While results vary by material and technique, this set presents a practical option for DIY enthusiasts and professionals seeking flexibility, confidence, and control when drilling through challenging surfaces. The dual-use design and organized package add convenience for on-site projects and workshop setups.

How to use and care

• Choose the appropriate bit size for your material and hole requirement.
• Mark the center, align with the EVA guide, and begin at a conservative speed to establish a clean entry.
• Use coolant for heat-sensitive materials if desired, and clean debris after drilling to maintain performance.
