BE-9881TB ERGO Through Blade Screwdriver Set, 6 Piece These Bahco ERGO Through Blade Screwdrivers are for fastening, loosening and chiselling. Its hexagon profile blade and bolster allow the use of a wrench for jobs requiring more torque. The blade continues through the handle with no loss of hammer blow energy. A metallic cap gives protection during jobs requiring high impact. The high-performance alloy steel blade has been chrome plated and entirely hardened for high protection against corrosion, a long life tool. A black oxide tip provides higher accuracy. Developed according to the scientific ERGO process. A three-component handle provides maximum user comfort. The soft material with ridged surface provides superior grip and greater force transmission. A flat face prevents the screwdriver from rolling away. It's easy to choose the right tip, thanks to the colour-coded handle* and permanent symbol on the domed end. This set of 6 contains: 4 x Slotted Screwdrivers: 3.5 x 60mm, 4.
