-
Fast Keyless Bit Swap: Tool-free design enables rapid single-handed bit changes to maximize job-site productivity.
-
Tactile Ribbed Sleeve: Non-slip molded outer shell provides maximum hand torque during manual tightening and loosening.
-
Directional Indicators: Molded arrow markings (“GRIP” / “RELEASE”) ensure intuitive, error-free operation.
-
Hardened Steel 3-Jaw Mechanism: Precision-machined internal jaws provide balanced clamping force to prevent bit slippage during drilling.
✔ Power Tool Upgrade: Ideal for carpenters, electricians, drywall installers, maintenance crews, and bulk B2B supply.
Upgrade your power tool performance and streamline bit changes with the SMT-715 Keyless Drill Chuck. Designed for cordless screwdrivers, handheld power drills, and light drill presses, this keyless chuck delivers maximum convenience without compromising gripping force or drilling accuracy.
The SMT-715 eliminates lost chuck keys and slow bit setups. Its durable ribbed outer sleeve is contoured to provide maximum friction, allowing users to apply strong hand torque effortlessly. Integrated directional arrows (“GRIP” and “RELEASE”) clearly guide users during bit insertion and removal. Inside, heat-treated alloy steel jaws grip round and hex-shank drill bits tightly, ensuring high concentricity and minimal radial runout across wood, metal, and plastic materials.
