DEWALT Masonry Drill Bit Set 7-Piece (DW5207) — Rock-Carbide Tips & Anti-Slip Shanks for Concrete

Built for contractors, remodelers and serious DIYers, this compact set includes commonly used diameters for anchor and through-hold work in masonry. The carbide tips increase cutting contact and toughness, a four-flute profile helps clear dust and rubble during drilling, and three flats on the shank prevent rotation inside compatible chucks. These bits are sized for typical 3/8" and 1/2" hammer drill chucks and are optimized for mechanical anchors and anchored fasteners.

How do these bits hold up when drilling concrete and block?

The DW5207 uses rock-carbide cutting faces designed to resist wear and maintain a sharp edge under percussion loads. The larger carbide contact area spreads impact forces for more consistent life compared with narrow-tipped bits. While not intended as a diamond or core solution, they handle standard anchor and through-hole tasks effectively.

• Rock-carbide tip increases cutting surface for longer service life
• Suitable for concrete, brick, block and artificial stone
• Intended for anchor holes and general masonry drilling

Will these bits stay secure in my hammer drill?

Yes — these bits feature three flats on the shank that reduce slippage in many chucks, improving torque transfer and keeping the bit seated under load. That design helps maintain consistent drilling depth and reduces the chance of spinning inside the chuck. Note that a few other DEWALT models use different shank finishes; check compatibility with your specific chuck size.

• Three-flat shank resists rotation in common drill chucks
• Fits most 3/8" and 1/2" hammer drill chucks for versatility
• Improves torque transfer for steadier drilling performance

How does the bit geometry affect debris removal and drilling speed?

The four-flute configuration is designed to evacuate dust and fragments as you drill, helping prevent clogging at the tip and enabling faster progress through masonry. Cleaner flutes reduce binding and heat buildup, which helps the tip remain effective longer during repeated holes. For best results, use steady pressure and intermittent pulling to clear debris on deeper holes.

• Four flutes channel dust and chips away from the cutting face
• Reduced clogging means more efficient drilling and less tip wear
• Works well with hammer/action mode on rotary hammer and percussion drills

What sizes are included and when should I choose this set?

The set contains common diameters used for anchor and fastening applications: 3/16" x 3", 1/4" x 4" (two pieces), 5/16" x 6", 3/8" x 6" and 1/2" x 6". These lengths cover shallow to moderate-depth anchor installations without requiring a long-bit specialty purchase. The assortment is a practical starter kit if you regularly install mechanical anchors or need reliable masonry drilling for fixtures.

• Contents: 3/16"x3", two 1/4"x4", 5/16"x6", 3/8"x6", 1/2"x6"
• Sizes chosen for standard anchor and through-hole needs
• Compact set that covers most routine masonry tasks

Who is this for: The DEWALT DW5207 set is aimed at professional tradespeople and committed DIYers who need a dependable selection of percussion-rated masonry bits for anchors, electrical and plumbing pass-throughs, or general concrete work. If you require diamond tooling, deep-core drilling, or specialized SDS-plus bits for heavy rotary hammers, consider dedicated products; for everyday anchor drilling in masonry, this set is a solid, cost-effective choice.
