38mm x 600mm SDS Plus Rotary Hammer Drill Bit - Concrete Ready

In this review the 38mm x 600mm SDS Plus rotary hammer drill bit is evaluated for contractors and serious DIYers who need a large-diameter masonry bit that reaches deep into slabs and walls. The bottom line: this bit is best for heavy-duty drilling in concrete, brick and stone where a long reach and solid cutting action matter. The review highlights build, cutting performance and practical limitations so you can decide if this single 600mm length fits your rig and jobsite needs.

Key Features

• Cutting diameter: The 1-1/2 in (38mm) head makes large through-holes quickly for anchors, sleeves and conduit runs.
• Total length: The 600mm (23.6 in) length provides deep reach for drilling through thick walls and slabs without extensions.
• Shank type: The SDS Plus shank ensures secure engagement with compatible rotary hammers for steady drilling under load.
• Material: Steel body with a carbide tip keeps the cutting edge hard and wear-resistant for masonry applications.
• Applications: Designed specifically for concrete, brick, cement and stone work so users get predictable performance on masonry.

Who It's For

This bit is aimed at professional tradespeople and experienced DIYers who need a single large-diameter masonry bit with substantial depth - for example running conduit, installing through-bolts or drilling core-like passages in block or poured concrete. It suits users who already own an SDS Plus rotary hammer and want a durable carbide-tipped option for repetitive masonry drilling.

Those who should look elsewhere include anyone using a compact drill without SDS Plus compatibility, or users who require variable lengths or a full core-bit for precise circular cutting; smaller diameter work or delicate tile work also calls for a different, more specialized bit.

Pros & Cons

Pros

• Large 38mm cutting diameter drills substantial holes quickly, saving time on rough masonry tasks.
• Long 600mm length reaches deep through slabs and walls without the need for extensions.
• Carbide tip and steel construction provide robust wear resistance and consistent cutting action.
• SDS Plus shank offers a secure fit and efficient power transfer with compatible rotary hammers.

Cons

• At this size and length the bit can be demanding on tools and operators; one user reported the drill bending under heavy use, so care is required with alignment and rigging.
• Its single fixed length limits versatility if you need shorter or longer options for varied jobs.
