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.
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.
Safety First: Always wear safety goggles and secure your workpiece properly.
Speed Selection: Use medium-to-high speeds for wood; larger diameters require lower speeds.
Maintain Sharpness: A sharp drill bit produces cleaner holes and operates more efficiently.
Steady Feeding: Apply moderate, consistent pressure without excessive force.
Chip Evacuation: Withdraw periodically when drilling deep holes to remove chips.
Material Limitation: For wood and wood products only - never use on metal.
