Use sanding or carving accessories for small contours, edges and craft details with light, controlled passes.
The HOTO 4V 35-in-1 Cordless Rotary Tool Kit is designed for detailed DIY, crafting and light repair work. Its pen-style body, five fixed speed levels, organised accessories, LED-lit work area and charging dock make it easy to move from carving and sanding to grinding, cutting and polishing.

The internal motor is tuned for controlled carving, sanding, grinding, trimming and polishing rather than heavy construction work. Let the selected accessory and rotation do the work; excessive side pressure can stall the tool, overheat the accessory or mark the project.
Turn the ring to choose one of five speed levels. The tool remembers the last selected level after power-off, helping you return to a familiar setup.

HOTO states up to 50 minutes of continuous work on a full charge. Stand the tool on its supplied dock between sessions so it stays stored upright and ready for the next small project.
The official imagery demonstrates the included system on wood, leather, metal and stone-like craft material. Always fit the correct accessory, secure the workpiece and test on scrap material first.

Use sanding or carving accessories for small contours, edges and craft details with light, controlled passes.

Guide an appropriate engraving point slowly to create lettering and decorative lines in suitable craft leather.

Clean small compatible metal surfaces with the correct brush and low pressure; use the disc metal brush only at speed level 3 or below.

Use a rated cutting disc only on suitable small workpieces, keeping your body outside the disc’s plane and the guard between you and debris.

Use a compatible diamond accessory and gentle passes for small decorative details; manage hazardous mineral dust appropriately.

Smooth tight curves and small surfaces using the supplied sanding bands without forcing the drum into the material.

The manufacturer’s manual lists approximately 240g net tool weight. A sanded TPU exterior and angled front rubber area improve grip, while the charging dock and modular boxes keep the compact system ready for repeat use.

The integrated ring light illuminates the work area for detailed carving and finishing. HOTO states that it switches off automatically seven seconds after the tool is powered down.
The kit covers carving, drilling, sanding, grinding, brushing, polishing and light cutting. Small parts are separated into connected storage boxes instead of being left loose in the carry case.


The fitted zipped case keeps the tool and its small project accessories together between home, studio or hobby-bench use.

The organiser boxes separate consumables from mounted accessories so the right piece is easier to select, inspect and return after it cools.

HOTO’s copper head clip is designed for secure, concentric attachment and the brand states compatibility with 3mm accessories. The snap-on transparent cover helps redirect some flying particles while keeping the work visible; it is an aid, not personal protective equipment.
Both descriptions refer to the same product: HOTO sells it as the 4V Cordless Rotary Tool Kit, while the QWLDM001 manual lists 3.7V as the rated battery voltage.
The control ring provides five selectable levels across an approximate 5,000–25,000 RPM no-load range and remembers the last selected level. HOTO does not publish every intermediate RPM value.
No. The rotary tool itself charges through contact pins when it is placed on the supplied charging base. The base is connected to USB power with the supplied cable; a wall adapter is not confirmed.
HOTO states up to 50 minutes of continuous work on a full charge. Actual runtime varies with speed, pressure, accessory, material, temperature and battery condition.
The included groups support carving, small drilling, sanding, grinding, brushing, polishing and light cutting. It is intended for detail-oriented DIY and craft work rather than high-load construction tasks.
HOTO states compatibility with 3mm accessories, and the manual separately lists an included 2.35mm clamping head. Verify the attachment’s shank fit, dimensions, material suitability and maximum rated speed before use; physical fit alone does not make an accessory safe.
Yes briefly. HOTO states that the ring light switches off automatically about seven seconds after the tool is powered down.
No. It helps redirect some particles but does not fully contain dust, fragments or a failed accessory. Always use suitable eye protection and any additional protection required by the task and material.
This 4V model is the lighter precision-focused option with five fixed speed levels, 5,000–25,000 RPM and dock charging. The 12V Pro is the higher-power model for more demanding work and uses a different accessory package and charging system.
