15 Piece Professional Vacuum Brazed Diamond Core Bit Set & M14 Threaded Masonry Hole Saw Kit

Equip yourself with the ultimate drilling solution for high-end masonry and tiling projects. This 15-Piece Diamond Core Bit Set is engineered for the most demanding substrates, including porcelain, granite, marble, and reinforced ceramics. Utilizing advanced Vacuum Brazing Technology, industrial-grade diamonds are fused to the steel core at high temperatures, ensuring a bond that is significantly more durable and heat-resistant than standard electroplated bits. Whether you are installing bathroom fixtures, routing kitchen plumbing, or working with decorative stone, this comprehensive kit provides the speed and precision required for a clean, professional finish.

Core Utility & Performance Features

• Vacuum Brazed Diamond Technology: Features high-density industrial diamonds bonded with superior thermal stability. This ensures aggressive cutting action and a long service life, allowing for effortless dry drilling in hard-brittle materials without the immediate need for water cooling.

• 15-Piece Master Set: A complete range of diameters from 6mm to 68mm, ensuring you have the exact size for every task—from small anchor bolts and electrical wiring to large-scale drainage pipes and socket installations.

• High-Speed M14 Connection: Designed with a standard M14 female thread, allowing for direct mounting onto professional angle grinders for high-RPM stability. The included adapter expands compatibility to standard power drills, providing total job site flexibility.

• Clean-Cut Performance: Engineered to provide smooth, rapid penetration with minimal edge-chipping. The 10mm diamond coating height ensures consistent performance throughout the life of the bit, even in dense stone and vitrified tiles.

• Dry & Wet Versatility: While optimized for high-performance dry drilling, these bits can be used with water to further reduce friction and extend the lifespan of the diamond edge during high-volume production.

Snagg It Tip

To achieve the cleanest finish on high-gloss porcelain tiles, start your cut at a 45-degree angle to create a small "crescent" pilot groove. Once the bit has a secure purchase, slowly bring the tool to a vertical 90-degree position. This prevents the bit from skidding across the finished surface. For the longest tool life, avoid applying excessive downward pressure; instead, use a slight "circular" rocking motion while drilling to allow dust to escape the core and keep the diamonds cool. Having the 68mm bit in this kit is a lifesaver for standard electrical box cutouts in tiled walls, ensuring a perfect fit every time.
