Will this chuck adapter fit my drill/screwdriver?
It fits any tool with a 1/4" quick-change chuck, which is the most common type for drills, screwdrivers, and impact drivers.
-
How does the dual-size chuck design benefit different drilling tasks?
The 0.3-3.6mm chuck is for delicate jobs like electronics repair, gripping tiny bits precisely. The 0.6-8mm chuck handles general wood or metal drilling. It enables easy switching between precision and heavy-duty tasks, maximizing versatility.
-
How do I swap between the two chucks?
Just pull the quick-change collar on your tool to release the current chuck, then insert the other chuck’s 1/4" shank until it clicks.
-
How tight should I make the chuck?
Tighten the sleeve by hand until the bit feels firm (no wiggling). Don't over-tighten, as this can damage the chuck or bit.
-
What if the chuck won’t tighten?
Please check two things: 1) Is the bit inserted straight? 2) Does the bit size match the chuck (e.g., 0.5mm bits need the silver chuck)? If not, try a different bit.
