2.35mm Mini Brass Drill Chuck Shaft Arbor Adapter for Small DC Motors & Rotary Tools

The 2.35mm Mini Brass Drill Chuck Shaft Arbor Adapter is a precision-machined brass coupling sleeve engineered to connect mini brass collet chucks to small DC motors, micro rotary tools, and benchtop spindles.

Key Features

• Precision-Machined Solid Brass: Machined to tight tolerances for a concentric, wobble-free fit between motor shafts and micro chucks, minimizing vibration and runout at high speeds.
• Optimal 2.35mm Bore Fit: Specifically sized for 2.35mm motor shafts commonly used in micro drill presses, miniature DC motors, and electronic rotary tools.
• Secure Set-Screw / Threaded Interface: Ensures positive torque transfer without slipping during precision stone drilling or PCB fabrication.
• Corrosion-Resistant Durability: Solid brass alloy resists wear, galling, and environmental oxidation in wet lapidary environments.

Recommended Applications

• Lapidary gemstone core drilling and carving setups.
• Micro PCB hole drilling, electronics prototyping, and hobby crafts.
• Jewelry bench fabrication, stone setting, and fine detailing.

Installation Guidelines

• Slide the adapter onto the clean 2.35mm motor shaft until fully seated.
• Secure the set-screws evenly to ensure concentric axial alignment.
• Mount the brass collet chuck body, insert the appropriate collet and drill bit, and verify true rotation before applying load.
• Always use water lubrication when drilling hard gemstones, minerals, or glass.
