Create an undersized hole so concrete tapping screws fit tightly once they're threaded into place. These bits are slightly smaller than the matching screw size. They have a carbide tip that resists wear and heat to stay sharp.

Connect these hollow bits to a vacuum system, and they'll suck up dust while drilling. Use them to meet OSHA standards for silica dust exposure when drilling in concrete, brick, and other powdery masonry material. These bits are especially useful for cutting holes for adhesive anchors—you don't need to clean out the hole before installing. They have a titanium nitride (TiN)-coated carbide tip that resists wear and heat to stay sharp.

Remove a core of material with these hollow bits to make larger holes than fluted masonry bits. They're often used for installing pipe and conduit through brick and concrete. The carbide tip resists wear and heat to stay sharp.

Quickly make smooth plunge cuts—the staggered flute design, drill/mill cut style, and carbide coating on these bits let them cut at higher speeds than other router bits. Staggered flutes combine the fast chip clearing and cutting speeds of straight flutes with the smooth finish of spiral flutes. The flute switches sides halfway up the shaft, making the bit more balanced and better at producing clean finishes than standard router bits. These bits have a pointed end, making downward plunge cuts easy.

Made of carbide-tipped high-speed steel, these bits provide faster cutting speeds and a longer tool life than standard high-speed steel bits. They do not have a pilot, so guide your router along a straight edge when hand routing to make accurate cuts.
