Strong Screw Drill-Bit Set (PACK OF 6)

Lock-In Power, Zero Cam-Out

MagnaGrip Pro bits fuse S2 alloy strength with rare-earth magnetism, giving every screw a rock-solid hold—whether you’re framing studs or tuning carburetors.

Strong Magnetic Grip

Built-in magnets keep fasteners attached in awkward angles and overhead installs—no more dropped screws.

Reinforced S2 Alloy Steel

Heat-treated S2 outlasts standard CR-V bits, tackling continuous drive jobs without rounding.

Anti-Slip Serrated Tips

Precision “shark-tooth” cutters bite deep for a tight fit, preventing cam-out and head stripping.

Torsion-Optimized Waist

Black slim-waist zone flexes under high torque, absorbing impact to protect both bit and screw.

6 Lengths • 9 Sizes

From 25 mm stubbies for tight engine bays to 150 mm reach for deep recesses—switch fast with any 1/4" quick-change chuck.

Q: How to demagnetize if needed?
A: Slide bit through a demagnetizer slot 2-3 times to remove charge.
