Dewalt DW5221B25 Carbide Percussion Drill Bit 1/8x3 in 25pk

Product Description

The DEWALT DW5221B25 is a carbide-tipped percussion drill bit designed for drilling into masonry, concrete, and similar hard substrates. Sized at 1/8 inch diameter by 3 inches in length, this bit delivers the impact resistance and cutting performance required for anchor hole preparation, conduit runs through block walls, and similar trade applications. Sold in a bulk pack of 25, the DW5221B25 is suited for contractors and service techs who need reliable masonry drilling capability on the job. The carbide tip is engineered to withstand the repeated impact cycles of a rotary hammer or hammer drill without premature wear.

This bit is appropriate for residential and light commercial applications where small-diameter masonry penetrations are required. Common uses include electrical rough-in through concrete block, plumbing sleeve penetrations, HVAC bracket anchoring, and pool equipment pad fastening. The 1/8 inch diameter suits small pilot holes and anchor placements where a compact bore is specified. The bulk quantity of 25 units makes this format practical for stocking a service vehicle or job-site storage.

Key Features

• Carbide tip construction for extended durability in masonry and concrete
• 1/8 inch diameter x 3 inches length for small-bore penetration work
• Percussion-rated design compatible with rotary hammer and hammer drill operation
• Bulk pack of 25 bits reduces restocking frequency on active job sites
• Consistent geometry across the pack supports repeatable hole sizing

Compatibility

Designed as an OEM-style percussion drill bit for use in standard rotary hammer and hammer drill chucks accepting 1/8 inch round shank tooling.

Installation Notes

Masonry drilling is typically performed by electricians, plumbers, HVAC technicians, and general contractors during rough-in and equipment mounting phases. Always confirm the correct hammer drill or rotary hammer setting before use, and wear appropriate eye and respiratory protection when drilling masonry. Consult applicable codes such as the NEC or IFGC for anchor and sleeve placement requirements near gas lines or electrical conduit. Do not use percussion bits in standard drill-only mode for extended periods, as this can reduce bit life and accuracy.
