Frequently Asked Questions

Q: What drill bit sizes does this keyless drill chuck fit?

A: The SLADE keyless drill chuck accommodates round-shank drill bits ranging from 1.5mm to 13mm, making it compatible with the vast majority of standard drill bits used in woodworking, metalworking, and general construction.

Q: Which adapter shank type should I choose — Hex, SDS-Plus, or Square Female?

A: Choose Hex Shank if you're using a standard impact driver; select SDS-Plus if you're working with an electric rotary hammer; and opt for the Socket Square Female adapter if you need to fit a socket or square-drive connection. All three options use the same 1/2-20UNF mount and 3-jaw chuck body.

Q: Will this drill chuck work with my cordless impact driver?

A: Yes — as long as your impact driver accepts the corresponding shank type (Hex, SDS, or Square), this chuck adapter will convert it to hold standard round-shank drill bits from 1.5mm to 13mm with a secure 3-jaw grip.

Q: Is the chuck keyless, or do I need a chuck key to tighten it?

A: This is a fully keyless chuck — simply hand-tighten the collar to secure your drill bit. No chuck key is required, which makes bit changes fast and convenient, even when wearing work gloves.
