The Bosch Professional Impact Screwdriver Bits, PH2‑PH2 (double‑ended, 65 mm, 2‑piece pack) are premium-quality impact-rated bits tailored for high‑torque uses. Expertly crafted from heat‑treated S2M-grade tool steel, they offer enhanced tip hardness, wear-resistance, and long life under heavy-duty impact loading. Each bit features a torsion zone to absorb shock peaks, minimizing tip breakage and extending runtime—making them ideal for use with impact drivers. The 65 mm length strikes a balance between reach and control in tight spaces, while the magnetic PH2 tips grip screws snugly for accurate, slippage‑free screwdriving. The bits come in Bosch’s black-oxide finish, with clear laser-marked size stamps for fast identification, and each head has two PH2 ends—doubling their useful life. This compact 2‑piece set (Bosch model no. 2608522408/2608521042) makes for a reliable, budget-conscious addition to any tradesperson’s kit. Note that Bosch generally classifies screwdriver bits as consumables and does not cover them under its standard 1‑year professional warranty.
