A drill designed for micro and small-diameter hole work where surface finish quality is paramount. It covers an extremely fine size range of 0.025 to 0.100 inches, making it well suited for precision micro-drilling applications.

The integrated shank construction—where the cutting face and shaft are formed as a single unit—minimizes runout even at very small diameters, while the thin-wall design reduces friction and heat generation during cutting. It is the right tool for precision machining of optical components and semiconductor wafers where even the slightest chipping or thermal deformation cannot be tolerated.

Segmented Diamond Core Drills

A drill that delivers superior cooling and chip evacuation for large-diameter holes of 6 inches and above. The gaps between segmented cutting faces allow coolant to flow in and swarf to clear efficiently—the defining feature of this design. By controlling heat buildup—the central challenge in large-diameter machining—and reducing load on the cutting segments, the drill enables stable, continuous cutting over extended runs.

Bond hardness and other segment parameters can be closely customized to match the equipment environment, making it well suited for machining quartz ingots and large ceramic blocks, where heat retention is a persistent challenge and the risk of material fracture is high.

Dual Diamond Core Drills

A compound machining drill that cuts both the inner and outer diameter in a single pass. Completing two cuts in one operation reduces total machining time while keeping the inner and outer diameter positions accurately aligned. The metal bond construction offers strong thermal resistance, helping the drill maintain dimensional stability during extended continuous machining runs. It is well suited for production lines for electronic components and sensors where both throughput and machining precision are equally critical.

BRAEMAR Is Built for Advanced Machining of Precision Instruments
and Hard, Brittle Materials

BRAEMAR is the right fit for fine machining applications where even minor chipping or thermal deformation must be eliminated—such as semiconductor wafers and optical components—and for high-volume production lines processing electronic components or sensors that require inner and outer diameter machining to be consolidated into a single operation.

With the ability to minimize runout in micro-diameter work and handle large-diameter and compound machining, BRAEMAR is a manufacturer well suited for brittle material machining environments where conventional tooling struggles to deliver stable, repeatable results.

Preventing chipping in hard, brittle materials while maintaining tight dimensional tolerances

BRAEMAR's core bit lineup is engineered specifically for precision machining of hard, fracture-prone materials such as sapphire and quartz (fused silica). The defining characteristic is a high thermal dissipation structure that pairs high-quality synthetic diamond with a metal bond matrix.

This proprietary design prevents thermal expansion and runout during machining, allowing the majority of models to meet tight tolerance specifications as a standard capability. The ability to consistently hold precise dimensions minimizes micro-chipping and cracking in the workpiece, contributing directly to improved yield in manufacturing environments where strict quality standards are non-negotiable.

Custom design that solves real production challenges and delivers stable output

BRAEMAR goes beyond selling off-the-shelf tooling. When standard products cannot meet the requirements, the ability to customize specifications in fine detail is a core strength—covering diamond grit size, bond hardness, core bit diameter, and wall thickness.

BRAEMAR also supports fully custom designs that incorporate dedicated coolant grooves and internal channels to promote heat dissipation and chip evacuation. By building in structures that actively reduce heat and cutting load, tools retain their geometry and cutting performance for longer—helping prevent excessive wear and machining defects even during high-load continuous production runs.

BRAEMAR Maintenance & After-Sales Support Network

In addition to pre-purchase consultation on bit selection, BRAEMAR offers custom design and manufacturing consultation tailored to each customer's machining conditions and material requirements—making it straightforward to implement the right tooling for the specific application.

After a tool enters service, BRAEMAR supports machining condition reviews, specification adjustments, re-sharpening, and repair work—all of which contribute to stabilizing output quality and extending tool life. Same-day shipping is available for consumable core bits, reducing the risk of production stoppages when an urgent replacement order is needed.
