1/4" Hex to 4mm Micro Bit Adapter
This is a precision-engineered adapter designed to bridge the gap between your standard 1/4" (6.35mm) bit drivers and 4mm Micro Bits (often used for electronics, smartphones, and eyewear repair).
Specifically designed with the iconic Wera Kraftform aesthetic in mind, it fits perfectly into the Wera 838 RA S Ratchet screwdriver and any other standard bit holder or drill chuck.
Features
- Universal Compatibility: Use any 4mm precision bit in your favorite 1/4" hex driver.
- Compact Design: Low profile to ensure you don't lose the "feel" of precision work.
- Perfect Fit: Designed with tight tolerances to prevent bit wobble.
Recommended Print Settings
To ensure the adapter can handle the torque required for screwdriving, please follow these guidelines:
- Material: PETG, ASA, or PC (Polycarbonate) are recommended for durability. PLA works for light tasks but might crack under high torque.
- Infill: 100% (Solid) is mandatory for structural integrity.
- Layer Height: 0.12mm or 0.16mm for better internal tolerance accuracy.
Post-Processing
Depending on your printer's calibration, the 4mm hex hole might be a "press-fit." If it's too tight, you can gently heat the end of a metal 4mm bit and press it in, or use a small file to clean up the edges.
