The bottom line: its 380mm total length and 42mm cutting diameter make it a practical choice when deep, large holes in brick, stone or cement walls are required, and the alloy steel body with a + type carbide tip is the single biggest reason to consider it for demanding masonry work.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize and reach:\u003c\/strong\u003e The 380mm (15 in) total length lets users drill deeper cores through thick walls and blocks without changing tools.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge diameter:\u003c\/strong\u003e The 42mm (1-2\/3 in) cutting diameter is suited to anchoring, through-holes and heavy-duty fixings where smaller bits would not suffice.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSDS Max shank:\u003c\/strong\u003e The SDS Max shank handle provides secure retention and compatibility with rotary hammer tools that accept large shanks for sustained impact work.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial construction:\u003c\/strong\u003e Alloy steel body combined with a + type carbide tip balances toughness with cutting performance on stone, brick and concrete surfaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMasonry applications:\u003c\/strong\u003e Designed specifically for masonry, brick, stone and concrete, it performs well on cement walls and similar substrates.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe bit is aimed at professional tradespeople, masons and serious renovators who regularly drill large holes in concrete, brick or stone and need a full-length bit with SDS Max compatibility.
