Milwaukee 2101-22 M4™ 1/4" Hex Screwdriver Kit
Eliminate stripped screw threads, damaged wall plates, and user fatigue during repetitive fastening. The Milwaukee® 2101-22 M4™ 1/4" Hex Screwdriver Kit delivers precision torque control in an ultra-compact, two-position pivoting body engineered for commercial electricians, IT/data technicians, low-voltage installers, and assembly line pros.
Delivering 44 in-lbs of peak torque, this 4V driver features a high-precision 21-position clutch with auto shut-off that cuts motor power instantly the moment your target torque is reached. The dual-speed gearbox allows seamless shifting between 200 RPM for delicate low-speed driving and 600 RPM for fast pilot drilling and screw setting. With its two-position swiveling handle, switch between a traditional inline screwdriver and an angled pistol grip with a quick twist to access recessed panels and cramped cabinets. Powered by Milwaukee M4™ REDLITHIUM™ 2.0Ah batteries, this kit delivers over 200 drives per charge and comes complete with two battery packs and a dedicated charger to keep your workflow running continuously without downtime.
- Precision Auto Shut-Off Clutch: 21 distinct clutch settings cut power immediately upon reaching the dialed torque, preventing overtightening and stripped screw heads.
- 2-Position Pivoting Handle: Transforms between a straight inline driver for tight clearances and an ergonomic pistol grip for extra driving leverage.
- Two-Speed Gearbox: Dual speed ranges (0–200 RPM and 0–600 RPM) provide tailored control across delicate plastics, sheet metal, and wood.
- One-Handed Quick-Change Chuck: 1/4" hex collet holds bits firmly and enables fast, single-handed bit swaps on the fly.
- Ultra-Lightweight Profile: Weighs less than 1 lb and measures under 10" in straight mode, minimizing hand and wrist fatigue during all-day overhead work.
- Complete 2-Battery Kit: Includes (2) M4™ REDLITHIUM™ 2.0Ah batteries, M4™ charger, and a Phillips driving bit.

Frequently Asked Questions
How does the auto shut-off clutch work?
Unlike standard mechanical slipping clutches that continue to ratchet and vibrate against fasteners, the electronic auto shut-off clutch completely stops motor rotation the instant your preset torque is reached. This protects delicate electrical cover plates, plastics, and precision threads from stripping.
Can this screwdriver be used in both straight and pistol-grip positions?
Yes. The tool features a locking swivel hinge that allows you to configure it as a straight inline screwdriver for tight, narrow access, or rotate it into a pistol-grip setup for standard ergonomic driving and extra leverage.
Are M4 batteries interchangeable with Milwaukee M12 tools?
No. The M4 system uses dedicated, slim 4-volt REDLITHIUM stick-style battery packs engineered specifically for ultra-compact precision hand tools. They are not compatible with M12 or M18 battery platforms.
What is included in the 2101-22 kit?
The kit includes the M4 1/4" Hex Screwdriver (2101-20), two M4 REDLITHIUM 2.0Ah lithium-ion battery packs, an M4 battery charger, and a double-ended screwdriver bit.
