Marvel 25MM X 400MM SDS Plus Drill Bit

SDS Plus compatibility means the bit has an SDS Plus shank that fits SDS Plus hammer drills. This design allows for quick bit changes, efficient hammering action, and improved drilling performance in masonry applications.

Key features include curved flutes for improved chip removal, a tungsten carbide tip for wear resistance and longer life, high-grade construction for durability, and a specially designed shank for accurate drilling in SDS Plus tools.

Dimensions: 14 mm diameter x 210 mm length. Suitable for deep holes in concrete, brick, block, and masonry—useful for anchors, conduit routing, electrical boxes, and other installations requiring masonry holes.

Insert the bit into an SDS Plus hammer drill, mark your drilling point, start at a low speed with light pressure, then gradually increase speed while maintaining steady, perpendicular alignment. Clear chips regularly and avoid forcing the bit to prevent binding or overheating.

Wear eye protection and a dust mask, secure the workpiece, and use hearing protection if needed. Avoid side loading, keep the drill perpendicular to the surface, and allow the tool to cool if it becomes hot. Ensure the drill and bit are appropriate for hammer drilling.

The tungsten carbide tip provides wear resistance for longer life, while curved flutes improve chip removal for cleaner holes and reduced friction. Drilling performance will vary with substrate hardness and drilling technique.

Key differences to consider include flute design, tip geometry, carbide grade, and overall length. This Marvel bit emphasizes curved flutes for chip clearance and a durable carbide tip for longer life, making it a solid choice for deep masonry drilling. When comparing, look at length, tip material, and shank compatibility to match your drill and project needs.

Common uses include drilling deep holes for anchors, threaded inserts, electrical conduits, plumbing lines, and other fixtures that require reliable masonry holes in concrete or masonry walls and floors.

Always ensure your tool is powered off before installation, insert the bit fully into the SDS Plus chuck, verify perpendicular alignment, start at low speed, apply steady pressure, and clear chips frequently. Avoid forcing the bit and stop if it binds or overheats.

Longevity is influenced by carbide quality, flute design, drilling speed, substrate hardness, and maintenance. The tungsten carbide tip and curved flutes in this bit help enhance wear resistance and chip clearance, contributing to better value over time for repeated masonry drilling tasks.
