Overview

The Toolant Impact Allen Wrench Drill Bit Set is a versatile 20-piece collection designed to tackle a range of fastening tasks with confidence.

Designed for impact drivers and heavy screw driving

Engineered to withstand higher torque, the torsion zone absorbs torque peaks to reduce the risk of bit breakage during rapid driving or stubborn fasteners. CNC machined tips pair with a hardened core to deliver precise engagement and lasting strength, even under demanding conditions.

• torsion zone absorbs torque peaks to reduce breakage risk
• extended 4 inch length provides extra reach in tight spaces
• CNC machined tips with hardened core for higher bit strength
• manganese phosphate surface adds rust resistance
• strengthened magnetic bit helps pick up screws quickly

Materials, range, and craftsmanship

Crafted from S2 alloy steel, the bits resist wear while the manganese phosphate finish helps resist rust. The magnetized tip assists with fastener alignment, so you can focus on accuracy and speed. The 4 inch long design strikes a balance between reach and control, making it suitable for deeper holes and space-constrained tasks.

• S2 steel body for durability and value
• manganese phosphate coating for rust resistance
• magnetic tip enhances screw handling
