A 40-piece impact-rated driver bit set (Phillips, Torx, square, slotted, nut drivers, plus a magnetic holder) whose FLEXTORQ zone flexes up to 15 degrees to absorb impact torque so tips don't shatter. CNC-machined tips seat precisely to reduce cam-out. It's driving bits only, a companion to a drill bit set; tips still wear under daily use.
Pros
- FLEXTORQ zone flexes up to 15 degrees to absorb impact-driver torque so tips don't shatter
- CNC-machined tips seat precisely and reduce cam-out that strips screw heads
- 40 pieces cover Phillips, Torx, square and slotted plus nut drivers and a magnetic holder
Cons
- Driving bits only - not for boring holes, so it's a companion to a drill bit set, not a replacement
- Even impact-rated tips wear out and need replacing under heavy daily use
- The 1 in insert bits need the included holder to reach recessed fasteners

Frequently Asked Questions
- Why do impact drivers need special bits?
- Because an impact driver delivers sudden rotational hammer blows that shatter ordinary bit tips. The FLEXTORQ zone flexes up to 15 degrees to absorb that torque instead of transmitting it into the tip.
- Does this set include drill bits?
- No — it is driving bits only. It is a companion to a drill bit set, not a replacement, so plan on owning both if you are starting from nothing.
- Why do screw heads still strip with good bits?
- Usually cam-out from a loose fit. These tips are CNC-machined to seat precisely, which measurably reduces stripping. Note the 1 in insert bits need the included magnetic holder to reach recessed fasteners, and even impact-rated tips wear out under heavy daily use.
