2.35mm Mini Brass Drill Chuck Shaft Arbor Adapter for Micro Drill Press & Compact DC Motors

The 2.35mm Mini Brass Drill Chuck Shaft Arbor Adapter is a precision lathe-turned brass adapter engineered to couple mini brass collet chucks to micro drill press spindles and compact DC hobby motors with a 2.35mm motor shaft.

Key Features

• Precision-Machined Solid Brass Body: Machined to tight tolerances to provide a secure, concentric, wobble-free interface between a 2.35mm motor shaft and micro chuck, minimizing runout and vibration at high speeds.
• 2.35mm Input Bore Fit: Engineered specifically for micro drill presses, compact DC hobby motors, and benchtop rotary spindles.
• Standard 3.17mm (1/8") Output Bore: Pairs seamlessly with standard mini brass collet chucks (0.5–3.2mm capacity) for micro drilling and detail carving.
• Corrosion-Resistant Durability: Solid brass alloy ensures longevity and resists wear in demanding workshop environments.

Recommended Applications

• Precision PCB drilling and electronics prototyping.
• Lapidary gemstone core drilling and detail stone carving.
• Jewelry fabrication, micro stone setting, and craft modeling.

Installation & Usage Guidelines

• Press the 2.35mm adapter firmly and squarely onto the clean motor shaft until fully seated.
• Mount the collet chuck body onto the adapter's output end.
• Insert the appropriate collet, load your drill bit or bur shank, and tighten securely before operating.
• Always use water as a coolant when drilling hard stones, minerals, or glass.
