Eagle Cutting Tool SDS4350-3750-12-D Sds Masonry Drill Bit

Product Description

The EAGLE CUTTING TOOL SDS4350-3750-12-D is an SDS-shank masonry drill bit designed for drilling into concrete, block, brick, and similar hard masonry materials. It measures 3/8 inch in diameter with a 12-5/8 inch overall length, making it well suited for through-penetrations and anchor holes that require extended reach. The Delta tip geometry is engineered to improve cutting efficiency and reduce heat buildup during rotary-hammer drilling. This bit is used by electricians, plumbers, HVAC installers, and general contractors who need clean, accurate holes in masonry substrates.

This bit is intended for use with SDS-style rotary hammers in residential and commercial construction and retrofit applications. Common use cases include setting anchor bolts, drilling conduit penetrations through masonry walls, running pipe sleeves, and installing HVAC equipment mounts. The 12-5/8 inch overall length provides the reach needed for full wall-thickness penetrations in standard CMU and poured-concrete construction without extensions.

Key Features

• 3/8 inch diameter for standard anchor and conduit penetration sizing
• 12-5/8 inch overall length allows full-depth penetrations in typical masonry walls
• Delta tip geometry improves cutting speed and reduces heat accumulation
• SDS shank provides secure tool retention and efficient hammer energy transfer
• Suited for concrete, block, brick, and similar hard masonry substrates

Compatibility

Designed for use with SDS-chuck rotary hammers. Fits any standard SDS (SDS-Plus) rotary hammer accepting 3/8 inch shank masonry bits.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with rotary-hammer operation and applicable codes. Confirm the SDS chuck is fully locked before drilling and wear appropriate eye and hearing protection. When drilling near existing conduit, pipe, or rebar, verify wall substrate with a scanner before starting. Allow the bit to cool between extended drilling cycles to maintain tip integrity.
