## Description

6PCS 1/4 to 4mm Bit Adapter, 1/4 to 4mm Hex Adapter/ Hex Screw Driver Bit Adapter, Micro Bits Drill Extension Socket Shank, Outside To System 4mm Inside Micro Bit Drill Extension Socket Shank for Precision Bits Set Screwdriver Converter

## Features

- Steel Construction & Dual-Size Options:​​ This set includes 6 pieces of 1/4 to 4mm bit adapter(3 long and 3 short versions) made from steel for maximum torque transfer. The hex screw driver bitad apter features precise 6.35mm (1/4") to 4mm conversion with hardened steel construction, ensuring long-lasting performance in professional and DIY applications
- Precision Bit Conversion System:​​ Designed as micro bits holder components, these adapters allow standard 1/4" drill chucks to securely hold 4mm micro bits. The 1/4 to 4mm hex adapter maintains perfect bit alignment while the extended reach versions (outside to system 4mm inside micro bit drill extension socket shank) provide access to tight spaces where standard adapters can't reach
- Universal Tool Compatibility:​​ The micro bits drill extension sockets hank design works with all major brand drills, impact drivers, and screw guns. These hex screw driver bit adapter units are essential for electronics repair, jewelry making, and precision woodworking where standard 1/4" tools are too large for 4mm bits and fasteners
- Good Design:​​ Unlike cheap adapters, these 1/4 to 4mm bit adapter pieces feature precision-machined hex sockets that prevent bit slippage under load. The micro bits holder design ensures positive bit retention while the steel construction minimizes vibration
- Wide Application :​​ From watchmaking to RC model building, these outside to system 4mm inside micro bit drill extension socket shank adapters bridge the gap between standard and micro tools. The 1/4 to 4mm hex adapter works equally well for automotive dash repairs, computer maintenance, and crafting projects requiring both power tool convenience and precision bit sizes
