1-1/4 in x 18 in SDS Plus Rotary Hammer Drill Bit - Carbide Tipped

In this review the 1-1/4 in x 18 in SDS Plus rotary hammer drill bit is presented as a practical choice for tradespeople and serious DIYers who need a durable masonry bit for brick, stone, and concrete. The bottom line: its cemented carbide YG8C tip and cross centring point deliver fast penetration and controlled chipping on heavy materials, making it worth considering when a large-diameter hole is required. The pack's universal SDS PLUS shank compatibility means it fits most rotary hammers, which simplifies tool selection on the jobsite.

Key Features

• Cemented carbide YG8C: provides high hardness and durability for chipping and drilling in masonry materials, reducing tip wear under heavy use.
• Cross centring tip: aids initial penetration and helps drill a more precise hole in brick, stone, and concrete.
• U-shaped flute design: clears debris quickly to keep the bit running cooler and prevent clogging during extended drilling.
• Wide material adaption: suitable for brick, block, stucco, stone, and concrete so one bit can cover common masonry tasks.
• SDS PLUS shank: a universal shank style that fits most rotary hammer drills from major brands for easy interchangeability.

Who It's For

This drill bit is aimed at contractors, masons, and homeowners who regularly drill larger holes in masonry and need a tool that balances cost and performance. Its strength and tip design work well when drilling anchor or through holes where durability and a clean entry are important.

It may not be the right choice for users requiring strict OEM-level durability every time; some customers reported mixed longevity under very heavy or unusual use. If you need metric-standard sizing or guaranteed OEM-grade performance each time, consider higher-end branded alternatives.
