Part of the BluGranite Turbo series, this bit measures 5\/8 inch in diameter with a 12-inch overall length and a 10-inch usable flute length. The hex shank design is impact-rated, allowing use in both hammer drill\/drivers and impact drivers. A 4-grind head adds two extra cutting angles compared to standard masonry bits, contributing to faster penetration rates and extended service life. Bosch-made carbide construction is specified for durability under heavy, repetitive loads. This package contains 5 bits.\u003c\/p\u003e\n\u003cp\u003eThe HCBG21T is suited for drilling into brick, block, concrete, and general masonry in residential and light commercial settings. The multi-grind carbide centering tip promotes accurate bit starts, reducing walking on uneven or hard surfaces. Milled U-flutes with deep-cut spirals channel dust and debris out of the hole efficiently, helping maintain cutting speed throughout the bore. The impact-rated hex shank makes this bit a practical choice for tradespeople who carry impact drivers as part of their standard kit and need a masonry bit that works across multiple tool platforms without a separate adapter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eImpact-rated hex shank compatible with hammer drill\/drivers and impact drivers\u003c\/li\u003e\n  \u003cli\u003e4-grind head with two additional cutting angles for longer life and faster speed\u003c\/li\u003e\n  \u003cli\u003eMulti-grind carbide centering tip for accurate starts in brick and masonry\u003c\/li\u003e\n  \u003cli\u003eMilled U-flutes with deep-cut spirals for fast dust and debris removal\u003c\/li\u003e\n  \u003cli\u003eBosch-made carbide construction rated for heavy-load durability\u003c\/li\u003e\n  \u003cli\u003ePackaged as a 5-piece set for jobsite backup supply\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe HCBG21T hex shank is impact-rated for use in standard hammer drill\/drivers and impact drivers.

Secure the hex shank fully into the tool chuck or bit holder before operation, and confirm the tool is set to hammer or rotary-hammer mode as appropriate for the application. Always wear eye protection and a dust mask when drilling into masonry materials. Depress the trigger only after the bit tip is positioned against the work surface to avoid skipping.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUsable Length\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Hex, impact-rated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.45 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ROBERT BOSCH TOOL GROUP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HCBG21T\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOSCH","offers":[{"title":"Default Title","offer_id":51563029791026,"sku":"HCBG21T","price":110.55,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca8e5a80d6a40fc08eb22a77f7824d76.jpg?v=1786488525","url":"https:\/\/voomisupply.com\/products\/bosch-hcbg21t-blugranite-turbo-carbide-hammer-drill-bit-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
