An extra-long masonry drill bit is a specialized tool used when standard-length bits cannot penetrate the full depth of a structure. This Marksman set is specifically designed for “through-hole” drilling. Whether you are installing outdoor tap piping, routing electrical conduit through an external wall, or setting deep anchor bolts in a foundation, these 400mm bits provide the necessary clearance to finish the job in one pass.
Constructed from high-grade carbon steel, each drill bit in this set is built to withstand the high temperatures and vibrations generated by SDS or standard hammer drills. The Tungsten Carbide Tip (TCT) is vacuum-brazed to the shaft, ensuring the cutting edge remains sharp even when encountering hard flint, brick, or cured concrete. The wide-flute spiral design effectively clears dust and debris from the hole, preventing overheating and jamming.
The Marksman 400mm Set provides the most common diameters required on a job site. The straight-shank design is compatible with all standard 13mm geared or keyless chucks found on percussion and hammer drills. Because the bits are 400mm long, they offer the stability needed to maintain a straight path through uneven masonry, ensuring your exit hole is exactly where you planned it.
Total Length: 400mm.
Quantity: 3 Piece Set.
Tip Material: Industrial-grade Tungsten Carbide.
Shank Type: Standard Round/Hex (Drill Chuck compatible).
Ideal For: Concrete, brickwork, breeze blocks, natural stone, and mortar.
By adding the Marksman 3-Piece 400mm Masonry Drill Bit Set to your toolkit from ECO HEAT SHOP, you are ensuring you have the reach and power to tackle the toughest structural drilling tasks.
