More Information About 230N.m Multifunctional Cordless Screwdriver Brushless
1. What's the actual torque of this brushless cordless screwdriver when driving screws?
From SENGXIN's engineering standpoint:
- Our lithium‑battery cordless screwdriver / driver is built with a high-efficiency brushless motor plus a robust gearbox to deliver strong torque output. The design goal is to produce torque comparable to many standard impact drivers/screwdrivers on the market. For example, many 1/4″‑hex cordless impact drivers reach around 230 N·m max torque under ideal load conditions.
- In real‑world screw‑driving (wood, metal sheet, medium‑density materials), you can expect strong, consistent torque enough for a wide variety of common screws, lag screws for light‑medium jobs, and fastening into wood or light metal.
- Because torque depends on battery voltage, bit quality, screw size, and material hardness, actual usable torque will vary. With a fresh full charge and appropriate bit, the tool will deliver near its peak.
From SENGXIN's perspective: we aim for a balance — enough torque for demanding fastenings, while keeping the tool controllable, compact, and safe.
2. How long does the lithium battery last per charge?
Battery runtime depends heavily on the battery capacity (Ah), the load applied, and how intensively the tool is used. From SENGXIN's design & testing results:
- For moderate screw‑driving or light drilling tasks (e.g. furniture assembly, wall‑plug installation, light framing), a fully charged lithium battery typically allows tens to over a hundred screws without significant power drop — enough for a full small-to-medium project.
- Under heavy load (e.g. longer screws, harder materials, or repeated heavy tasks), runtime is shorter, but the tool remains effective until battery is depleted.
- Because SENGXIN uses efficient brushless motors and optimized power electronics, battery discharge is managed carefully to improve usable runtime while preserving motor/battery lifespan.
- For extended or larger jobs, using a second battery pack (if available) is recommended to maintain work continuity.
For typical residential or workshop tasks, you can expect a full battery to last through a typical work session.
3. Is the 1/4 inch hex collet compatible with standard screwdriver bits?
Yes — compatibility is part of our design philosophy:
- SENGXIN's 1/4″ hex chuck/collet is a standard size used broadly in the industry. This means virtually all standard screwdriver bits, impact‑rated bits, and hex‑shank drill bits that fit 1/4″ hex will work with our driver. This ensures flexibility and convenience for users who already own or purchase standard bits.
- Quick‑change hex collets (common in modern cordless drivers) allow one‑handed bit changes, which improves workflow efficiency on site or at home.
- Because of this standardization, users don't need proprietary bits — they can choose from a wide market of bits (wood, metal, masonry, etc.), giving improve versatility.
From SENGXIN's perspective, using standard interfaces keeps the tool more usable, future‑proof, and user-friendly.
4. Can this tool handle large screws or lag bolts, or only light/medium‑duty screwing?
- Our cordless driver is designed to handle light to medium‑duty tasks very well: wood framing, cabinetry, furniture assembly, metal‑sheet fastening, wall anchors, etc. For standard screws and moderately tough materials, the power and torque are sufficient.
- For large screws or lag bolts, especially when driven into wood or materials that require high torque, the tool can perform — especially if you use a high‑quality impact‑rated bit, fully charged battery, and allow the motor to do the work (i.e. avoid forcing the screw manually).
- For very heavy‑duty tasks (e.g. very large lag bolts, dense hardwood, structural bolts, or deep masonry anchors), the performance will approach the upper limit of what a 1/4″‑hex driver can safely handle. For such cases, SENGXIN recommends using a larger‑format tool (impact wrench, bigger drill, or corded heavy‑duty tool), because torque, bit strength, and drive stability all become limiting factors.
This tool is well‑suited for most household, workshop, and light‑to‑moderate construction tasks — and with proper technique, can tackle many larger screw/bolt jobs — but it is not a substitute for heavy‑duty structural fastening gear.
