Concrete Screw Drill Bit 1/4" x 8

This straight-shank drill bit is sized at one-quarter inch diameter and eight inches overall length for concrete screw installation. The chromium-vanadium steel construction suits professional tradespeople and DIY users who need reliable hole drilling in masonry substrates.

Sustained drilling in concrete

CrV material resists heat buildup during repeated holes so the cutting edges stay sharp longer than standard carbon steel bits. The four-and-three-quarter-inch maximum drilling depth matches typical anchor embedment requirements without bottoming out in deeper holes.

Straight shank with 7/32" diameter

The reduced shank fits three-jaw chucks and quick-change adapters common on cordless hammer drills and rotary hammers. Straight profile allows full chuck engagement for minimal run-out and efficient torque transfer in daily site work.

Questions about this item

How much heat does the 1/4" x 8" concrete screw drill bit generate during extended drilling in masonry?

The CrV steel construction dissipates heat effectively during continuous use, while the straight flute design clears dust to reduce friction buildup in concrete, brick or block.

What shank size must my drill chuck accept to use the 1/4" x 8" concrete screw drill bit?

The bit has a 7/32 in shank diameter, so your drill chuck must accommodate at least that size for a secure grip.

Will the 1/4" x 8" concrete screw drill bit fit older drills with a 3/8" keyed chuck?

Yes, the 7/32 in shank fits standard 3/8" keyed or keyless chucks found on older corded and cordless drills.
