toolant TA01001001 Metric Impact Hex Bit Set, 10-Piece, Magnetic S2 Steel

For metric hex fasteners on a car, bike, or home repair, this toolant set gives you ten bit sizes in one compact kit. Its 2-inch bits have 1/4-inch quick-release hex shanks for use with a drill or impact driver.

CNC-machined tips, an S2 alloy steel body, and a hardened core are designed for impact screwdriving. A torsion zone helps absorb torque peaks, while the magnetic tips help hold fasteners in place as you work.

Need one set to cover a range of metric hex sizes? This kit includes sizes from 1.5 mm to 8 mm, so you can move between fasteners without buying each bit separately.

Worth noting

The ten-piece range includes 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 5 mm, 6 mm, 7 mm, and 8 mm bits. That spread is useful for repair tasks involving different-sized internal hex fasteners, from smaller fittings to larger hardware. Each bit is 2 inches long and has a 1/4-inch quick-release hex shank, making the set suitable for compatible drills and impact drivers.

The CNC-machined tips are paired with an S2 alloy steel body and hardened core. For impact-driver work, the torsion zone is designed to absorb torque peaks and help reduce the chance of bit breakage. Magnetic fastener retention can make it easier to keep a screw positioned on the bit while starting or driving it. The manganese phosphate finish is intended to help prevent rust.

Everyday use

Keep the set with your driver for jobs where metric hex fasteners come up in more than one size. At a workbench, you can select the bit that matches the fastener rather than pause to find or purchase individual sizes. For vehicle or bicycle maintenance, the range makes a handy assortment for common screw-driving tasks, match the bit to the fastener before applying the driver.

Customers describe the bits as functional and appreciate having a useful spread of sizes. Feedback on durability is mixed: some buyers find them durable, while others report stripping or cracking. The set’s impact-oriented construction and magnetic tips are practical features for driver-based work, while choosing the correct size and keeping the bit properly seated helps support a controlled fit.

Best use cases

This is a useful format for home repairs, automotive work, and other screw-driving jobs that use metric internal hex fasteners. The set is designed for use with a drill or impact driver, and its quick-release hex shanks make it straightforward to switch between the included sizes. For a single repair that always uses one known size, an individual bit may be a simpler purchase, this set is better suited to a tool kit that needs several metric options ready to hand.

Before you decide

Which sizes are included? The set contains metric bits in 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 5 mm, 6 mm, 7 mm, and 8 mm sizes.

Can I use these with an impact driver? Yes. The bits are intended for impact-driver use and have 1/4-inch quick-release hex shanks. They are also compatible with drills.

What helps hold a fastener on the bit? The tips are magnetic, helping retain screws during positioning and driving.

When it makes sense

Choose this set when your repair or maintenance kit needs a practical range of metric hex sizes for drill- or impact-driver use. Its ten-size selection, magnetic fastener retention, and impact-focused design bring the bits together for home, automotive, and general screw-driving tasks.
