Eagle Cutting Tool SDS4350-3125-12-D Sds Masonry Drill Bit

Product Description

The EAGLE CUTTING TOOL SDS4350-3125-12-D is an SDS-shank masonry drill bit engineered for rotary hammer drilling in concrete, block, brick, and other masonry materials. With a 5/16-inch cutting diameter and a 12-5/8-inch overall length, this bit reaches deep embedment depths required for anchor setting, conduit penetrations, and through-wall applications. The SDS shank provides positive locking engagement in SDS rotary hammers, delivering efficient energy transfer and reduced operator fatigue. Electricians, plumbers, HVAC installers, and general contractors rely on this bit type for rough-in penetrations and anchor installations in masonry construction.

This bit is suited for residential and light commercial applications where rotary hammer access to concrete walls, foundations, CMU block, and brick is required. Common install scenarios include anchor bolt drilling for equipment mounts, conduit sleeve penetrations, and structural fastener holes. The 12-5/8-inch overall length provides the reach needed for deep-set anchors or through-wall penetrations without extension adapters.

Key Features

• 5/16-inch cutting diameter for standard anchor and fastener hole sizes
• 12-5/8-inch overall length allows deep embedment and through-wall drilling
• SDS shank design locks positively into SDS rotary hammers for efficient percussion drilling
• Designed for use in concrete, brick, block, and masonry substrates
• Lightweight at 0.28 pounds for reduced tool-end weight during overhead or extended-reach work

Compatibility

Designed as a replacement or stock bit compatible with standard SDS rotary hammers used in masonry drilling applications.

Installation Notes

This bit is installed and used by electricians, plumbers, HVAC technicians, and other trades performing masonry penetrations. Insert the SDS shank fully into the rotary hammer chuck until it locks before drilling. Always wear appropriate PPE including eye protection and dust control measures when drilling masonry. Confirm anchor manufacturer requirements for hole diameter and depth tolerance before drilling.
