High-Precision Diamond Core Drill Bits & Micro Drills | Custom & Stock Options

Why Choose Diamond Core Drill Bits?

Diamond core drill bits are engineered for precision and durability. What sets these tools apart is the use of industrial diamonds impregnated into the bond matrix of the drill. These diamonds are the actual cutting agents, delivering unmatched hardness and sharpness for clean, efficient cuts—even on the hardest materials like ceramics, composites, and advanced metals.

Whether you are working with a standard setup or using a highly specialized system, the right diamond core bit directly impacts surface finish, tolerance levels, and tool life. A poor match between the drill bit and your application can result in costly errors, material waste, and subpar results.

Custom Solutions for Critical Applications

We manufacture diamond micro drills and core drill bits starting as small as .001" (25 microns) in diameter. Our catalog includes a wide range of standard options in stock, but we also offer custom fabrication based on your drawings and performance specifications. From diamond and CBN to CVD- and PCD-coated carbide, we offer the ideal solution for every budget and application.

We support:

  • Custom diameters and lengths

  • Tight tolerances

  • Specialized tip radii

  • Coating options based on material needs

    When synthetic or natural diamond isn't feasible, carbide tooling—coated or uncoated—can often meet performance targets more economically.

Find the Right Diamond Core Bit for Your Job

Choosing the correct diamond core drill bit is perhaps the single most important factor in your operation’s success. No matter how advanced your drilling equipment may be, without the proper drill bit, you won’t achieve the desired surface finish or dimensional precision.

We’re here to help. UKAM Industrial Superhard Tools offers both off-the-shelf and fully customized tools to match your exact needs. Whether you're working on micro-electronics, optoelectronics, or advanced composites, we’ll recommend the right solution to match your materials and application.
