Product Specification

Professional Metric Wood Auger Drill Bit | 6mm - 25mm Diameter | Extra Long Ship Auger for Deep-Hole Timber Boring (230mm/450mm/600mm)

1. Product Concept: Precision Industrial Boring

Our Metric Wood Auger Series is the professional choice for deep-hole drilling in construction timber, cross-laminated timber (CLT), and heavy hardwoods. Engineered with a Solid Center Design, these bits provide superior rigidity, ensuring that even at depths of 450mm or 600mm, the hole remains perfectly straight.

Unlike standard bits, the auger's self-feeding screw tip and high-clearance flute geometry allow for effortless penetration into dense substrates with minimal manual force, making it indispensable for structural engineering and heavy carpentry.

2. Technical Specifications Table (Metric)

Our metric range covers all standard industrial diameters, available in three primary lengths to suit various project depths.

3. Engineering Excellence: The Auger Advantage

Self-Feeding Threaded Lead Screw

The precision-machined threaded tip pulls the bit into the wood automatically. This reduces the physical effort required by the operator and allows for consistent drilling speeds, especially when using cordless high-torque drills.

Solid Center & Wide-Flute Geometry

The "Solid Center" core provides exceptional torsional strength, preventing the bit from bending or snapping under high torque. Combined with wide, polished flutes, it ensures Turbo-Speed chip evacuation, preventing clogging in deep holes.

Single-Spur "Shear-Cut" Technology

The sharpened outer spur scores the perimeter of the hole before the main cutting edge engages. This delivers a Clean-Exit finish and smooth hole walls, which is critical for the tight fit of metric mechanical fasteners.

Universal Hex Shank

Every bit is equipped with a non-slip Hex Shank. Smaller diameters feature a 6.35mm (1/4") shank for impact drivers, while larger diameters utilize reinforced 10mm or 12mm shanks to handle massive boring torque.

4. Professional Applications

• Timber Framing: Boring deep holes for structural bolts and threaded rods in timber-frame housing.

• Electrical & Plumbing: Creating clean metric channels through multiple floor joists and wall studs.

• Log Home Construction: Precision drilling through thick log walls for electrical wiring and plumbing.

• Railway & Landscaping: Drilling through pressure-treated railway sleepers and landscape ties.

5. Packing & Global Logistics

• Individual Protection: Each bit is coated in anti-rust oil and housed in a transparent PVC hanging tube with metric size labeling.

• B2B Bulk Supply: 10–50 pieces per inner box; reinforced export cartons palletized for international sea and rail freight.

• OEM Customization: Precision Laser Etching for brand logos and metric size markings directly on the shank for professional identification.

6. FAQ (Frequently Asked Questions)

Q: Why use a metric auger bit instead of an imperial one?

A: In metric-standard regions, structural bolts (like M10 or M12) require a precise fit. Using an imperial bit can result in a hole that is either too tight or too loose, compromising the structural integrity of the joint.

Q: Can these bits handle wet or resinous wood?

A: Yes. The wide-flute ship auger design is specifically optimized to extract wet, "stringy" wood chips that would clog a standard twist or spade bit.

Q: Are these compatible with my cordless impact driver?

A: Metric sizes up to 10mm typically feature a 6.35mm (1/4") hex shank, which is fully compatible with impact drivers. For sizes above 12mm, we recommend a high-torque rotary drill for safety.
