Ingco 12mm x 310mm Professional TCT SDS-Plus Hammer Drill Bit – Heavy-Duty Tungsten Carbide Tipped Rotary Masonry Flute for Concrete, Stone, and Brickwork (DBH1211204)

Drilling deep anchor holes or routing utility lines through hardened concrete, solid brickwork, or dense masonry using standard impact bits is a highly inefficient process that risks burning out your tooling or locking up your rotary hammer. Standard round-shank masonry bits often slip inside the chuck jaw, causing immediate loss of torque and excessive friction heat that dulls the cutting edge. The Ingco DBH1211204 12mm x 310mm Professional TCT SDS-Plus Hammer Drill Bit is an industrial-strength masonry penetration solution engineered to deliver rapid material removal and perfectly true anchoring paths. Featuring an elongated 310mm structural length and a dedicated SDS-Plus shank fitting, this premium accessory enables masonry contractors, electrical installers, and structural builders to drive deep bores into building aggregates with total kinetic efficiency.

The exceptional clearing speed and extended service life of this rotary hammer bit stem from its premium Tungsten Carbide Tipped (TCT) head geometry. The ultra-hard carbide crown is cross-brazed onto a high-tensile, heat-treated alloy steel body, allowing it to withstand high-impact percussive forces without fracturing or losing its structural bite. Engineered with an optimized dual-spiral flute profile, the bit extracts crushed dust and concrete aggregate slurry directly from the tip of the hole. This prevents binding, controls operating temperatures, and reduces internal stress on your machine's gearbox drive. Outfitted with a standard SDS-Plus grooved drive interface, it locks seamlessly into professional rotary hammers to completely eliminate slip, maximize impact transfer, and ensure precise, round holes perfect for drop-in anchors.

Key Features

• Premium Tungsten Carbide Tip (TCT) – Forged with a high-density cemented carbide head that maintains sharp cutting edges and resists impact damage in stone.

• Universal SDS-Plus Drive Shank – Features standard grooved drive keys that lock flush into industrial rotary hammers, preventing chuck slippage and ensuring optimal energy transfer.

• Deep 310mm Extension Reach – Long-profile 310mm shaft provides the necessary clearance to drill through thick block walls or deep foundational concrete columns.

• High-Volume Dual Flute Geometry – Engineered to instantly pull pulverized masonry dust away from the tip, minimizing thermal stress and accelerating drilling speeds.

• Hardened Alloy Steel Body – Constructed from premium grade tool steel designed to resist bending or snapping under severe structural hammer-drill cycles.

• Plastic Hanger Display Pack – Supplied attached to an iconic branded plastic hanger layout for clean retail visibility and easy workshop hook organization.
