Tungsten Carbide Through Hole Drill Bits For Woodworking
Dia.4mm-15mm Hole Making Boring 70mm Length
Our Thru-Hole Drills are purpose-built for clean, precise
through-holes in wood, MDF, plywood, and laminates—never metal.
Choose from 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.
Ideal for cabinetmakers, furniture builders, and high-production
woodworking applications, these drills deliver long-lasting
sharpness, exceptional durability, and professional results in
every pass.
Tungsten Carbide Through Hole Drill Bits For Woodworking
Dia.4mm-15mm Hole Making Boring 70mm Length Features
Premium Construction & Durability: Manufactured using cutting-edge processes and nanostructured
alloys, this bit delivers exceptional longevity that outperforms
conventional tools through rigorous applications.
Flawless Finish Guaranteed: Achieve consistently smooth, clean holes free from tear-out,
vibration, or surface imperfections thanks to the
vibration-dampening design and ultra-precise cutting geometry.
Effortless High-Speed Drilling: Experience significantly reduced cutting resistance for faster
feed rates. The optimized flute geometry ensures rapid,
uninterrupted chip evacuation, preventing clogging and overheating.
Versatile Material Compatibility: Designed for efficient boring in diverse materials including
natural hardwoods, softwoods, engineered wood composites (plywood,
MDF, laminates), and rigid plastics.
Simple Plug-and-Play Installation: Ready for immediate use with any standard handheld power drill or
benchtop drill press - no specialized adapters required.
Quiet Operation: Engineered to minimize operational noise significantly, enhancing
user comfort during extended work sessions without compromising
power.
Stable & Accurate Performance: Micro-polished cutting surfaces and balanced body construction
provide exceptional torsional stability, ensuring straight,
true-to-size holes with minimal operator effort.
Suitable Matariel
Various hardwoods (such as oak, maple, walnut, etc.)
Softwoods
Plywood, laminate (fireproof board)
Medium-density fiberboard (MDF), particle board
Bamboo
Drill Bit Working Length (Drilling Depth)
This drill bit has a working length (effective drilling depth) of
70mm. This means it can drill through wood up to a maximum
thickness of approximately 70mm (approximately 7cm). Please note
that the drill bit holder (shank) is not included in the effective
drilling depth.
What should you pay attention to when using this drill?
Safety First: Wear safety goggles to protect your eyes from flying
sawdust. Ensure the workpiece is securely fixed.
Choose the appropriate speed: For wood and larger diameter drill
bits, medium-to-high speeds are recommended. Consult the tool
manual for specific speeds; larger diameters require lower speeds.
A speed that is too low can cause the drill bit to bind or produce
a rough hole; a speed that is too high can burn the wood or
accelerate drill bit wear.
Keep the drill bit sharp: A sharp drill bit is more efficient and
produces cleaner holes. If drilling feels labored, smoke appears,
or the hole surface is rough, the drill bit may be dull.
Feed steadily: Apply steady, moderate pressure to advance the drill
bit. Avoid excessive force that may break the drill bit or split
the wood. Allow the drill bit to cut freely.
Evacuate chips through the hole: When drilling deep holes, withdraw
the drill bit at appropriate times to help remove chips, or use
compressed air to blow out chips.
Special Materials: Use only for wood and its products; never for
hard materials such as metal.
