• Allied Bolt Suggest Best Practices/installations notes:


    • Use with Spline or SDS Max rotary hammer machines to drill large diameter entry holes for pipe or conduit in floors or walls.
    • The Bits enable a hammer drill or rotary drill to produce holes which are larger than the tool rating by cutting the only circumference of the hole.
    • Core bits are machined from a single piece of forged Steel to withstand continuous hammering and sustain long life.
    • The top or head of the bit is crowned to direct the hammering energy through the outside wall and into the cutting teeth.
    • The carbide cutting tips are made with a slightly negative cutting angle for use with rotary hammer machines.
