4-Cutter Spline Shank Bit

The ARTU 02061 is a 4-cutter drill bit with a spline shank designed for heavy-duty drilling in concrete and masonry. Its aggressive cutting geometry suits professional contractors who need fast material removal on job sites. The 23-inch overall length provides deep reach for through-hole applications in thick walls or structural elements.

Upgrade from standard 2-cutter bits

This bit replaces conventional two-cutter spline shank bits when drilling speed and hole quality become critical. The four-cutter head reduces vibration and prevents binding when hitting rebar, making the switch worthwhile for crews drilling multiple deep holes per shift. It fits existing spline-drive rotary hammers without adapter changes.

Sustained deep-hole drilling

Under continuous load the four carbide cutters share the cutting forces evenly, keeping the bit centred and reducing heat build-up at the tip. The long flute clears dust efficiently over the full 23-inch depth, so penetration rate stays consistent from start to finish. The spline connection transmits high torque without slipping during extended use.

Questions about this item

Will the 1-1/4" spline shank fit my rotary hammer?

The bit uses a standard spline shank interface that matches rotary hammers accepting 1-1/4" diameter spline connections.

How do I seat the spline shank correctly so it does not slip?

Align the spline grooves with the chuck splines, push until the shank bottoms out, then twist to engage the locking collar fully.

When should I replace this 23" bit?

Replace when the four cutter edges show rounded tips, reduced drilling speed, or visible carbide loss on any cutting face.
