Through Hole Tungsten Drill Bit Dia. 4mm-15mm Tungsten Carbide Bits

Our Thru-Hole Drills are purpose-built for clean, precise through-holes in wood, MDF, plywood, and laminates. Available in solid carbide-tipped or solid carbide constructions to match your performance and budget needs. The optimized point and cutting geometry ensure straight, accurate holes with minimal tear-out on both entry and exit, even in challenging materials.

• Premium Construction & Durability: Manufactured using cutting-edge processes and nanostructured alloys for exceptional longevity
• Flawless Finish Guaranteed: Achieve consistently smooth, clean holes free from tear-out or surface imperfections
• Effortless High-Speed Drilling: Reduced cutting resistance for faster feed rates with optimized flute geometry
• Versatile Material Compatibility: Efficient boring in natural hardwoods, softwoods, engineered wood composites, and rigid plastics
• Simple Installation: Ready for immediate use with standard handheld power drills or benchtop drill presses
• Quiet Operation: Engineered to minimize operational noise for user comfort
• Stable & Accurate Performance: Micro-polished cutting surfaces ensure straight, true-to-size holes

• Various hardwoods (oak, maple, walnut, etc.)
• Softwoods
• Plywood and laminate (fireproof board)
• Medium-density fiberboard (MDF) and particle board
• Bamboo

This drill bit has a working length (effective drilling depth) of 70mm, capable of drilling through wood up to approximately 70mm thick. Note that the drill bit holder (shank) is not included in the effective drilling depth.
