ANEX Ultimate Hard X Bit, +2 65mm, 5-Piece Set, ASKM5-2065

Ultra-thin shaft design that fits into tight spaces. The shaft diameter is 3.8mm (+2), which is much thinner than conventional stepped bits (4.5mm). This bit allows you to drive screws into even narrower gaps and makes it easy to see the screw heads. Outstanding durability and wear resistance. The use of new high-strength steel achieves a high hardness of HRC62.5 (maximum hardness). It is resistant to wear and maintains cutting edge precision better than conventional products. It also has excellent toughness, making it resistant to breakage and ensuring high durability. Comes with a magnet. Rust-resistant plated finish. Compatible with 40V (also compatible with 18V)
