1-1/2 in x 23.6 in SDS Plus Rotary Hammer Drill Bit - Heavy Duty

In this review the focus is on a single purpose: drilling deep into hard masonry with a robust SDS Plus bit. The 1-1/2 in x 23.6 in rotary hammer drill bit is aimed at contractors, remodelers and serious DIYers who need a long, large-diameter bit for concrete, brick, cement and stone. The single biggest reason to buy is its combination of a 1-1/2 in cutting diameter and a 23.6 in length, which lets the user reach well beyond standard bits while maintaining compatibility with SDS Plus rotary hammers.

Key Features

• 1-1/2 in Cutting Diameter: Provides a large, clean hole suitable for heavy anchor bolts or through-holes in masonry work.
• 23.6 in Total Length: Reaches deeper into walls and slabs so installers can drill without splicing or switching tools.
• SDS Plus Shank: Ensures secure, easy insertion and compatibility with a wide range of rotary hammer tools.
• Steel Body with Carbide Tip: Delivers rigid shank strength and a carbide cutting face for effective penetration of hard materials.
• Designed for Masonry: Intended specifically for concrete, brick, cement and stone applications to reduce chipping and improve hole quality.

Who It's For

The bit is best for professionals and experienced DIYers who routinely drill large-diameter holes in concrete or thick masonry, such as when installing heavy anchors, through-conduits or pipe sleeves. Its long reach and SDS Plus compatibility make it practical on job sites where depth and durability matter.

It is not ideal for light home tasks, delicate finishing, or where smaller diameters are needed. Users who require frequent bit resharpening or who rarely drill deep masonry should consider shorter or smaller bits instead.

Pros & Cons

Pros

• Large 1-1/2 in diameter makes fast work of big anchor and sleeve holes.
• Long 23.6 in length lets users reach through thick walls and slabs without extensions.
• SDS Plus shank provides reliable retention and quick tool changes on compatible hammers.
• Carbide tip and steel construction offer strong drilling performance in hard stone and concrete.

Cons

• Wear resistance drew mixed feedback, so heavy daily use may show faster wear than some expect.
• Its size and length make it overkill for light tasks and require a suitably powerful rotary hammer.
