Convert Your Rotary Hammer or Impact Wrench into a Standard Drill Instantly!
Expand the versatility of your heavy-duty power tools with this premium 3-jaw keyed drill chuck assembly. Engineered with an SDS-Plus compatible round shank adapter, this kit allows you to seamlessly use standard smooth-shank twist drills, step bits, and hole saws on your rotary hammer drill (such as VEVOR, Bosch, DeWalt, and Makita machines) or compatible power drivers.
Key Features:
-
Classic 3-Jaw Keyed Design: Provides maximum gripping torque and precision alignment. Securely clamps bits from 1.5mm up to 13mm (1/16" to 1/2") to prevent slipping under heavy loads.
-
Premium 40Cr Construction: Drop-forged from high-grade chrome-vanadium steel (40Cr) and heat-treated for exceptional hardness, rust resistance, and long-term job site durability.
-
Universal 1/2"-20 UNF Thread: Features standard internal threading, allowing you to easily swap, upgrade, or detach the shank adapter component as needed.
