Keyless Chuck: The integrated spring provides a better grip and prevents accessories from falling out or flying during use, ensuring excellent stability. The keyless chuck accommodates a wide range of accessories from 1/32" to 1/8".

Metal Nut: Made of metal, strong and stable. Plastic nuts on the market often break during use, but all-metal nuts solve this quality problem. They are more durable and safer than plastic materials.

Brass Chuck: Made of high-quality brass, wear-resistant and durable. The brass chuck greatly improves accuracy and grips small drill bits more securely.

Not only does it maintain stability at high speeds, but it also improves work efficiency. WIDE APPLICATION: Our drill chuck sets are compatible with rotary tools and are ideal for light-duty accessories, including drill bits, sanding drums, polishing discs, wire and bristle brushes, and cut-off wheels. NOTE: Please measure and compare sizes before purchasing.
