It stands out for its 460mm length and 35mm diameter, which allow deep 330mm drilling without frequent re-positioning. The review focuses on real use: the bit drills cleanly through concrete and stone when paired with a proper SDS Max rotary hammer, and the alloy steel body with a carbide tip gives reliable cutting performance under heavy load.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e35mm diameter:\u003c\/strong\u003e Provides a wide, consistent hole size for anchor bolts and through-holes without wandering during drilling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e460mm total length:\u003c\/strong\u003e Reaches deep into walls or thick slabs so users can complete 330mm drilling depth without changing tools.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSDS Max shank:\u003c\/strong\u003e Ensures a secure connection to SDS Max rotary hammers for efficient hammering and reduced bit slippage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlloy steel body:\u003c\/strong\u003e Balances toughness and stiffness so the shaft resists bending during heavy-duty use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCarbide tip:\u003c\/strong\u003e Concentrates cutting strength at the point to penetrate concrete, brick, and stone effectively.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis drill bit suits tradespeople, concrete contractors, and experienced DIYers who need to bore deep holes in masonry, brick, stone, and poured concrete.
