Eagle Cutting Tool SDS4350-3125-6-D Sds Masonry Drill

Product Description

The EAGLE CUTTING TOOL SDS4350-3125-6-D is an SDS masonry drill bit engineered for rotary hammer drilling into concrete, block, brick, and other masonry materials. The bit measures 5/16 inch in diameter with a 6-5/8 inch overall length, giving tradespeople the reach needed for through-penetrations and anchor holes in standard wall assemblies. A delta-style carbide tip geometry improves chip evacuation and maintains cutting speed under load. At 0.28 pounds, this is a lightweight, single-piece bit suited for everyday production drilling on the job site. Licensed electricians, plumbers, and HVAC installers who route conduit, pipe, and refrigerant lines through masonry construction will find this bit a direct fit for those tasks.

This SDS masonry drill bit is intended for use with SDS-plus rotary hammers, the standard drive system found on most light- to mid-duty jobsite rotary hammers. Typical applications include setting anchor bolts, drilling wire and conduit penetrations through CMU block walls and poured concrete, and boring holes for pipe sleeves in residential and light commercial construction. The delta tip design is particularly effective in aggregate-heavy concrete where conventional spade tips tend to wander or lose geometry quickly.

Key Features

• Delta-style carbide tip for aggressive cutting and reduced bit wander in masonry
• 5/16 inch diameter suits common anchor and conduit sleeve hole sizes
• 6-5/8 inch overall length provides reach for standard wall penetrations
• SDS-plus shank for secure, tool-free chuck engagement on rotary hammers
• Lightweight construction at 0.28 pounds for reduced fatigue during repetitive drilling

Compatibility

Designed for use with SDS-plus rotary hammers as an OEM-style masonry drill bit for concrete, brick, block, and similar masonry substrates.

Installation Notes

This bit is installed and operated by any trade requiring masonry penetrations, including electricians, plumbers, and HVAC technicians. Always wear eye protection and a dust mask or respirator when drilling masonry, as silica dust is a respiratory hazard. Verify that no embedded conduit, rebar, or utilities are present in the drilling path before beginning. Do not use this bit in a standard keyless drill chuck — SDS-plus rotary hammers are required for proper shank engagement and safe operation.
