0.025″ – 0.100″ (shank mounted) stock Core Drills

0.025″–0.100″ Shank Mounted Diamond Core Drills | Braemar USA

Easy, Clean, and Accurate Small-Diameter Drilling

The 0.025″–0.100″ shank mounted Diamond Core Drills from Braemar USA make small, clean, and accurate holes in many hard materials. Although these holes are tiny, the drills stay stable and protect fragile parts during cutting. As a result, they are used in optics, electronics, labs, and many micro-machining jobs.

Stable Cutting With Smooth Control

Every drill includes premium synthetic diamond bonded to a precision-ground carbide shank. This combination keeps the tool running straight and reduces vibration. In addition, the thin-wall design lowers cutting pressure and limits heat. Because of this, users see cleaner holes and more consistent results. Furthermore, the tool’s steady cutting action improves repeatability.

Works Well on Hard and Brittle Materials

These drills perform well on materials such as:

• Sapphire

• Quartz and fused silica

• Ceramics

• Optical and specialty glass

• Silicon wafers

• Composites and engineered substrates

Since these materials break easily, the drill exposes diamond in a controlled way. Consequently, cutting becomes gentler, and edge chipping is reduced. Moreover, the even wear pattern helps maintain predictable drilling speeds.

Clean Holes at Very Small Sizes

Micro-diameter drilling often creates problems with coolant flow and feed pressure. Even so, these drills reduce those issues by staying sharp and resisting vibration. Consequently, each hole remains smooth at both entry and exit. In addition, the true-running head supports accurate geometry and tight tolerances. Therefore, operators can maintain part quality more easily.

Typical Uses

These drills are commonly used for:

• Optical parts and micro-features

• Semiconductor wafers and micro-channels

• Micro-fluidic and laboratory glass

• Precision ceramic components

• Sapphire watch parts

• Sensors, electronics, and R&D

Because the tools cut in a stable way, any job needing tiny, chip-free holes benefits from them.
