1-3/8 x 23.6 in SDS Max Rotary Hammer Drill Bit - Deep Masonry

In this review the 1-3/8 x 23.6 in SDS Max Rotary Hammer Drill Bit is evaluated for heavy masonry work and long-reach jobs. The bottom line: this bit is for tradespeople and serious DIYers who need reliable penetration through concrete, brick, stone and cement walls thanks to its long 600mm length and robust carbide tip. The review focuses on build, cutting performance and practical limits so a buyer can decide if this single-purpose masonry bit fits their job without sifting through specs alone.

Key Features

• Size and reach: The 35mm (1-3/8 in) diameter and 600mm total length let users reach deep cores and through thicker slabs without extensions.
• SDS Max shank: The SDS Max shank handle provides secure engagement with compatible rotary hammers for stable drilling and reduced slippage.
• Carbide tip: The + type carbide tip concentrates impact force for faster penetration into concrete and stone while resisting wear.
• Alloy steel body: The alloy steel construction balances toughness and weight so the bit can withstand repeated hammering on hard materials.
• Material versatility: Built for masonry, brick, stone and concrete, the bit covers the common substrates encountered on renovation and construction sites.

Who It's For

This drill bit is aimed at professional contractors and experienced DIYers who regularly drill large-diameter holes in concrete, block or stone and need the extra length of 600mm to access deep cores or pass services through thick walls. It works well for plumbing, electrical and anchor installations where a single long bit reduces the need to pull the drill back and clear rubble repeatedly.

People who should look elsewhere include occasional users who rarely tackle masonry or those who need a range of diameters and shorter bits for light work; this long 35mm bit is a specialized tool and may be overkill for small projects or for tools that lack an SDS Max chuck.

Pros & Cons

Pros

• Long 600mm length provides deep reach that reduces multiple setups on thick walls.
• SDS Max shank ensures a secure fit and stable transfer of hammer energy for efficient drilling.
• + type carbide tip improves cutting durability and helps maintain work quality across repeated holes.
• Alloy steel body offers a balance of toughness for construction site use.

Cons

• Mixed feedback on tip strength suggests heavy users should monitor wear and replace when necessary.
• Specialized size and SDS Max requirement make it unsuitable for light-duty drills and infrequent users.
