About this product
The Coro Masonry Drill Bit 12mm is designed to meet the rigorous demands of Kenyan construction projects. Made from high-carbon steel with a tungsten carbide tip, this bit delivers superior hardness, wear resistance, and impact durability. The tip maintains its sharpness over extended use, allowing for efficient penetration into reinforced concrete, solid bricks, and natural stone.
The 12mm diameter is ideal for medium- to heavy-duty masonry tasks such as installing wall anchors, curtain fittings, plumbing fixtures, and electrical boxes. Its spiral flute design ensures optimal dust removal, reducing heat buildup and minimizing bit wear during prolonged drilling sessions. This feature is particularly critical in Kenya’s hot, humid climates, where overheating can compromise drilling efficiency.
Performance & Compatibility: The cylindrical shank fits all standard drill chucks, including hammer drills and rotary drills. The bit is fully compatible with wall plugs, anchors, and masonry fasteners commonly used in residential, commercial, and industrial applications. Its design ensures even load distribution during hammer drilling, reducing vibration and operator fatigue while preserving hole accuracy.
Compliance & Trust: Coro masonry drill bits from Ngong Hills Merchants are KEBS-certified and come with eTIMS-compliant invoices, guaranteeing regulatory compliance and eligibility for 2026 tax deductions. This ensures contractors and homeowners purchase a product that meets strict Kenyan quality standards.
The heat-treated high-carbon steel body enhances toughness and resistance to bending, while the tungsten carbide tip allows the bit to maintain peak performance even under high-load drilling conditions. Whether installing anchor bolts for heavy fixtures, mounting curtain rails, or performing general masonry maintenance, the Coro Masonry Drill Bit 12mm ensures consistent precision and durability.
This bit is indispensable for residential, commercial, and industrial construction projects in Kenya, providing a reliable, professional-grade tool that reduces the risk of chipping, cracking, or material damage during drilling.
