HOTO SNAPBLOQ S-A01 Electric Precision Screwdriver Master Set (56-Piece)

The HOTO SNAPBLOQ S-A01 Electric Precision Screwdriver Master Set is a professional-grade, pen-style electric screwdriver engineered for electronics repair, PC building, 3D printer maintenance, hobbyist tinkering, and fine assembly work.

Designed as part of HOTO's revolutionary SNAPBLOQ modular tool system, the S-A01 combines a brushless motor, intelligent auto-stop torque control, and a comprehensive 56-piece S2 steel bit set into a sleek anodized aluminium body that is as precise as it is portable.

Powered by a built-in 3.7V 800mAh lithium-ion battery rechargeable via USB-C, the S-A01 delivers up to 60 minutes of continuous runtime per charge.

Three selectable torque and speed settings (0.05 / 0.35 / 0.5 Nm at 120 / 180 / 250 RPM) give you complete control across delicate and moderately demanding precision tasks.

The intelligent HOTO chip monitors torque in real time and automatically stops the motor the moment a screw reaches the correct tightness, eliminating any risk of stripping threads, cracking housings, or damaging sensitive components.

A built-in micro-lens star ring LED illuminates your work area with shadow-free light, and the ergonomic non-slip anodized aluminium grip with knurled texture ensures confident handling during extended use.

The tool also supports seamless manual mode, allowing you to switch to hand-tightening without removing the screwdriver from the fastener.

Features:

• Brushless Motor Technology: Enhanced stability, higher efficiency, quieter operation, and extended motor life compared to conventional brushed motors.
• Intelligent Auto-Stop Torque Control: HOTO smart chip automatically halts the motor when the target torque is reached, preventing overtightening, thread stripping, and component damage.
• 3 Torque and Speed Settings: 0.05 Nm at 120 RPM / 0.35 Nm at 180 RPM / 0.5 Nm at 250 RPM for versatile precision control across varying task requirements.
• 56-Piece S2 Steel Bit Set: Premium S2 alloy steel bits covering Phillips, flathead, Torx, hex, and more; housed in a magnetic modular storage case.
• 800mAh Rechargeable Battery: Up to 60 minutes of continuous runtime per charge; recharged via USB-C in approximately 90 minutes.
