Eagle Cutting Tool SDS4350-3125-9-D Sds Masonry Drill Bit

Product Description

The EAGLE CUTTING TOOL SDS4350-3125-9-D is an SDS-shank masonry drill bit designed for rotary hammer drilling into concrete, block, brick, and similar masonry substrates. The bit measures 5/16 inch in diameter with an overall length of 9-3/4 inches, giving technicians the reach needed for through-wall anchor holes and deep embedment applications. The Delta tip geometry is engineered to improve cutting efficiency and reduce heat buildup during continuous use. This bit is installed by licensed trades and experienced contractors who rely on consistent bore accuracy when setting anchors, conduit supports, or pipe hangers in masonry construction.

This bit is suited for residential and light commercial applications where SDS rotary hammers are the standard tool of choice. Typical use cases include drilling anchor bolt holes for equipment mounting, penetrations for electrical conduit or plumbing pipe sleeves, and bracket installations in poured concrete or CMU walls. The 5/16 inch diameter accommodates common anchor sizes used across HVAC, plumbing, and electrical trades.

Key Features

• SDS shank for positive tool engagement and fast bit changes on SDS rotary hammers
• Delta tip geometry for efficient material removal in concrete and masonry
• 5/16 inch diameter suited to standard anchor and fastener sizes across multiple trades
• 9-3/4 inch overall length provides depth capacity for through-wall and deep embedment drilling
• Lightweight at 0.28 pounds for reduced fatigue during overhead or extended drilling tasks

Compatibility

Designed for use with SDS-chuck rotary hammers commonly used in HVAC, plumbing, and electrical installation work on concrete, brick, block, and similar masonry materials.

Installation Notes

This bit is installed by electricians, plumbers, HVAC mechanics, and general contractors using SDS rotary hammers. Always wear appropriate PPE including eye protection and dust control measures when drilling masonry. Confirm anchor diameter and embedment depth requirements before drilling to ensure compliance with project specifications and applicable building codes. Never use an SDS bit in a standard drill chuck, as the shank is designed exclusively for SDS-compatible tool holders.
