Rex-Plus Nail Biter Auger Bit Set is engineered for demanding woodwork where nails and tough grain challenge ordinary bits. This 4-piece, 430 mm long set delivers clean, precise holes with less effort, so you can keep moving on even the most stubborn jobs.

Key features that boost on-site performance

• Screw-tip design: The self-feeding tip grabs the wood and pulls the auger forward, helping you punch through boards that hide nails without deflecting or binding.
• Centreless spiral: Optimizes chip clearance and minimizes clogging, delivering faster, smoother cuts and cooler operation.
• Re-sharpenable cutting edges: Extend tool life by maintaining a crisp cut through both hardwoods and softwoods with simple sharpening.
• Long reach of 430 mm: Ideal for deep holes in thick stock, cabinetry frames, decking, and furniture components where short bits fall short.
• 11.1 mm hex shanks: Secure, positive drive in a wide range of drills with minimal wobble for more accurate bore alignment.
• Four practical diameters: 16 mm, 20 mm, 22 mm, and 25 mm cover common hole sizes in woodworking projects.
• Organized storage: Comes in a sturdy carrying case, keeping all four bits protected, organized, and ready for transport.

Smart applications for the Nail Biter set

• Furniture making and repair—drill clean dowel holes or passage holes through nailed sections without tearing surrounding wood.
• Decking, cabinetry, and shelving—achieve precise, deep holes with smooth finishes that rival professional results.
• Renovation on older timbers—the screw tip helps you advance past hidden nails with reduced risk of bit damage.
• Pilot holes in hardwoods—control, accuracy, and efficient chip removal for repeatable drilling with consistent outcomes.

Why this Rex-Plus set stands out

Unlike standard wood bits, the Nail Biter auger’s screw-tip design minimizes wandering and binds less when nails are encountered, while the centreless spiral keeps chips moving away from the cutting edge for quicker, cooler cuts. The ability to re-sharpen extends tool life between replacements, making this set a reliable, long-term choice for serious woodworkers and DIY enthusiasts alike.

Practical tips for best results

• Begin with a slow drill speed to let the screw tip initiate the bite, then increase speed as the bit engages.
• Periodically back the bit out to clear chips and prevent clogging, especially in dense hardwoods.
• Keep the cutting edges sharp with a fine file when performance declines, and maintain the centerless spiral geometry for optimal chip evacuation.
