1-1/4 in x 23.6 in SDS Plus Rotary Hammer Drill Bit - Masonry

Our review looks at the 1-1/4 in x 23.6 in SDS Plus rotary hammer drill bit to see who should buy it and why. The bottom line: this bit is for professionals and experienced DIYers who need a long, large-diameter masonry bit that drills deep holes in concrete, brick and stone with consistent accuracy. The most compelling reason to buy is its combination of a 1-1/4 in cutting diameter and a 23.6 in length, paired with an SDS Plus shank that keeps the bit secure in rotary hammers while the carbide tip maintains cutting performance.

Key Features

• 1-1/4 in Cutting Diameter: Provides a large, clean hole suitable for heavy anchor bolts and sleeves without repeated reaming.
• 23.6 in Total Length: Reaches deep into thick walls or slabs so contractors can drill through large sections without extensions.
• SDS Plus Shank: Ensures a secure fit and reliable impact transfer in compatible rotary hammers for steady drilling control.
• Steel Body with Carbide Tip: Combines body strength and wear resistance at the cutting face for longer life in abrasive masonry.
• Designed for Masonry: Built specifically for concrete, brick, cement and stone so it performs where standard twist bits would fail.

Who It's For

This drill bit is aimed at masons, concrete contractors, and experienced tradespeople who regularly drill large, deep holes for anchors, through-feeds or bolt installations. The length and diameter are ideal when working on thick foundations, retaining walls or stone structures where reach and hole size matter.

It is less suitable for casual home users who only need small holes or those without an SDS Plus rotary hammer. If you only drill occasional small-diameter holes or use a standard corded drill, a smaller masonry bit or a different shank type will be a better match.
