  • Detailed information about this item

    The Alpen F4 Forte SDS+ hammer drill bit range has a patented 4X stepped profile and patented tip.
    Low wear, very long service life.
    A high efficiency drill bit for heavy-duty drilling in concrete, natural stone and brickwork.

    Overall length 450mm with a drilling depth of 400mm. 

    We do recommend that you pre-drill a same diameter starter hole when using this length of SDS+ hammer bit. 

    As a drill bit gets longer in length, potentially the force behind an SDS+ drilling machines hammering action could gradually dissipate through the length but a long drill bit could also whip, easily bend under drilling pressure and go out of shape. 

    Diameters 28.0mm, 30.0mm and 32.0mm all feature a 4-cutter, heavy duty drilling head.
