Spline Shank Drill Bit 1" x 23"L
This ARTU spline shank drill bit measures one inch in diameter and twenty-three inches in overall length. It is designed for heavy-duty drilling in concrete, masonry and stone using a spline-drive rotary hammer. The four-cutter head improves hole accuracy and reduces vibration during extended use. Professional contractors and serious DIY users will find it suited for deep anchor installation and through-bolting tasks.
Spline interface limits
The spline shank fits only rotary hammers that accept a spline-drive connection; it will not work with SDS-Plus, SDS-Max or standard three-jaw chucks. The twenty-three-inch length requires a tool with sufficient spindle travel and a stable side handle to control leverage. Deep holes demand frequent withdrawal to clear dust, otherwise the flutes pack and the bit binds. Users must match the bit to a compatible machine to avoid damage or injury.
Capacity and headroom
At one inch diameter the bit clears holes for large-diameter anchors, rebar dowels and conduit sleeves in a single pass. The twenty-three-inch working length reaches through thick walls, double-stud framing or floor slabs without an extension. In very hard aggregate or reinforced concrete the four-cutter geometry resists wear longer than two-cutter designs, but progress slows and operator fatigue increases. Extremely deep or continuous production drilling may exceed the practical limits of a single bit.
