900 Series chiseldrivers feature a Hexagonal “Pound-thru” blade designed for the heaviest duty working situations. Made from high quality bit material, the blade extends right through the handle, ensuring a full transfer of force, even when struck with a hammer. In addition an integrated impact cap and ductile tempered material inside the Kraftform handle significantly increase the service life, reduce any risk of splintering and absorb vibrations caused by hammering. Greater torque can also be transferred by attaching a ring spanner or open-end spanner to the hex bolster. Wera’s multi-component Kraftform handles fit perfectly into the hand, with hard zones that glide across the hand allowing for rapid working speeds, whilst softer gripping zones ensure greater torque transfer and extreme comfort during intensive use. Kraftform’s hexagonal anti-roll feature prevents any unwanted rolling off surfaces at the workplace.
