Spline Shank Drill Bit
The ARTU 02029 is a spline shank drill bit built for heavy-duty masonry and concrete work. It fits rotary hammers that accept a spline drive and is intended for professional contractors and serious DIY users drilling deep holes in hard materials.
Four-cutter head upgrade
The four-cutter geometry replaces older two-cutter designs by distributing the load across four cutting edges. The jump is worth it when drilling reinforced concrete or when you need faster material removal and longer bit life on a single job.
1 inch by 18 inch capacity
The 1 inch diameter and 18 inch overall length give comfortable reach through thick walls, floors or rebar grids. Headroom runs out when the hole depth exceeds the usable flute length or when the rotary hammer lacks the torque to drive a bit this large.

Questions about this item
What spline shank size does this 18-inch drill bit require?
The bit uses a spline shank that fits standard spline-drive rotary hammers; match the shank to your tool's chuck specification.
How do you seat the spline shank correctly so the bit does not slip?
Insert the shank fully until the drive lugs engage the chuck grooves, then tighten the chuck collar; a partial seat is the common error.
When should this four-cutter bit be replaced?
Replace the bit when the carbide cutters show rounded edges or the flutes no longer clear dust efficiently during deep-hole drilling.
