Niabraze manufactures vacuum-brazed diamond hole saws and core drills for cutting precise openings and circular features in glass, ceramics, quartz, composites, fiberglass, and other abrasive non-ferrous materials. Each tool combines an exposed monolayer of diamond with a durable bi-metal high-speed steel tool core to support fast, efficient cutting and dependable performance in high-volume production environments. For custom hole saws and core drills, please contact a member of our team for more information.
Vacuum-brazed construction is ideal for more aggressive cutting applications and increases diamond exposure while creating strong adhesion between the cutting edge and tool body.
Diamond hole saws and core drills provide enhanced cutting performance, extended tool life, and longer service life than conventional “toothed” tools when processing abrasive materials.
Hole saws and core drills with diamond edges are used to adapt challenging abrasives for end use by cutting circular features critical to final assembly and integration of other components.
Niabraze offers customers a broad selection of vacuum-brazed diamond hole saw sizes for aggressive industrial fabrication and production requirements. Standard diameters range from 9/16” up to 6”, with our most frequently requested sizes available for expedited shipping. Every standard tool features a 40/50 grit diamond cutting surface and a bi-metal high-speed steel core that is engineered to maintain integrity and tolerances through extensive usage. Custom-sized hole saws and core drills can be manufactured when our standard diameters do not align with your component, equipment, or finished-hole specifications.
In instances where hardened steel needs holes or circular access points added, diamond is no longer a viable option, and cubic boron nitride (CBN) should be used instead. This material is more adept at handling the high temperatures required in these scenarios due to the ferrous (iron) nature of the material. All CBN hole saws and cored drills are produced to deliver the same high-performance cutting characteristics of diamond equipment while adding some necessary longevity in large-volume cutting projects.
CBN hole drills can withstand the immense heat generated when cutting hardened steel materials, delivering accurate dimensions, reduced tool wear, cleaner edges, and reduced downtime in production due to blade replacement.
Another hardened material that requires CBN saw blades to accurately cut while resisting high heat levels, reducing edge distortion that compromises specified tolerances, and extending the service life of the equipment.
These are some of the most frequently asked questions about our CBN and diamond cutting tools. For any information not shown on the page or other questions, please contact a member of our team to learn more.
Diamond hole saws are engineered for abrasive non-ferrous materials such as glass, ceramics, quartz, carbon fiber, fiberglass, and other advanced composites. The specific tool configuration depends on the material thickness and hole size.
A diamond hole saw is generally used to create through-holes in sheets of material, panels, or finished components. A core drill may be selected for deeper cuts, thicker material sections, cylindrical core sample removals, or other specialized coring requirements.
Standard diameters range from 9/16” to 6”. Select sizes are kept in-stock for fast shipping (1-3 days) whereas more specialty or custom sizes can be manufactured upon request and shipped in 7-10 days.
Vacuum brazing hole saws creates a stronger bond between the diamond abrasive edge and the steel tool body. As these cutting tools are spinning at extremely high RPMs and maintaining continual contact with the material, ensuring a proper bond is paramount to tool functionality.
Yes. Our strip and replate services are available to all diamond or CBN hole saws regardless of the original manufacturer.
Our standard product line includes band saw blades, circular saw blades, hole saws, core drills, mounted wheels, and router bits. We offer diamond-coated products for non-ferrous materials and hardened CBN for ferrous materials.
For all specialty cutting, polishing, facing, or profiling projects that require custom tooling, our team can engineer and manufacture unique cutting tools to meet specific requirements.
Rather than ditch dull blades and tools, Niabraze provides fast-turnaround strip-and-replate services for all cutting tools, regardless of the original manufacturer. Our process quickly removes the existing cutting edge and replaces it with either diamond or CBN material.
