1-2/3 x 10 in SDS Max Rotary Hammer Drill Bit - Masonry Power

In this review the 1-2/3 x 10 in SDS Max Rotary Hammer Drill Bit is evaluated for professional and DIY work on concrete, brick and stone. The bottom line: this bit is for users who need a rugged, large-diameter masonry drill that fits SDS Max chucks and delivers dependable cutting from a carbide tip. It stands out because the 42mm diameter and 260mm length let operators bore deep holes for anchors and through-concrete work without switching to smaller pilot bits, making it a practical choice for contractors or serious renovators.

Key Features

• Large 42mm diameter: The 1-2/3 in cutting width creates a clean, oversize hole suitable for heavy anchors and sleeve applications without multiple passes.
• 260mm total length: The 10 in length provides reach into thick walls and deep pours while maintaining bit stability during drilling.
• SDS Max shank: The SDS Max shank profile ensures secure engagement with SDS Max rotary hammers for consistent hammering and rotation transfer.
• Alloy steel body: A hardened alloy steel shaft resists bending under load and tolerates repeated hammer action on masonry surfaces.
• Carbide tip: The multi-faceted carbide tip maintains cutting edges on abrasive materials like concrete and brick for prolonged life.
• Masonry-focused design: Built specifically for stone, brick and concrete so users avoid trial-and-error with general-purpose bits.

Who It's For

This drill bit is aimed at professional tradespeople, contractors and serious DIYers who use SDS Max rotary hammers and need to drill large-diameter holes in concrete, brick or stone. It works well for installing heavy anchors, through-bolts or when running sleeves through cement walls.

It is not ideal for light home projects that only require small pilot holes or for users with standard SDS Plus or non-SDS chucks; those users should look for smaller-diameter bits or bits compatible with their tool's shank size.

Pros & Cons

Pros

• Large 42mm diameter makes quick work of heavy anchor holes without repeated up-sizing.
• SDS Max shank delivers secure coupling and efficient power transfer in compatible rotary hammers.
• Carbide tip provides solid cutting performance on abrasive masonry materials.
• Sturdy alloy steel body resists bending and stands up to repeated hammering.

Cons

• Mixed customer feedback on tip strength suggests occasional variability in longevity under extreme use.
• Not compatible with SDS Plus or standard chucks without an adapter, limiting use to SDS Max tools.

Frequently Asked Questions

Will this bit fit my hammer?
It fits rotary hammers that accept SDS Max shanks; it will not fit SDS Plus or plain shank chucks without an adapter.

Is this suitable for reinforced concrete?
It is designed for masonry and concrete; performance on heavily reinforced concrete will depend on steel rebar encounters and may blunt the carbide tip faster.

How deep can I drill with this bit?
The total length is 260mm (10 in), which sets the practical maximum depth for through-holes or deep anchor placements.
