Product Specification

High-Speed Wood Spade Bit Set (6pcs) | Industrial Flat Bits for Impact Drivers | Self-Feeding Hole Cutter for Hardwood, Plastic & Construction Timber

1. Product Overview

Our 6-Piece Self-Feeding Spade Drill Bit Set represents the next generation of high-speed wood boring. Unlike traditional flat bits that require significant manual pressure, these bits feature a Precision-Threaded Lead Screw that automatically pulls the bit into the wood.

Combining the speed of a spade bit with the ease of an auger, this set is engineered for rapid rough-ins, electrical wiring, and plumbing installations. Forged from high-carbon steel and featuring an optimized cutting geometry, these bits deliver 10x faster drilling than standard flat bits.

2. Technical Specifications & Size Chart (SAE)

The set covers the six most essential diameters for modern construction and DIY projects.

3. Engineering Excellence & Key Advantages

Self-Feeding Threaded Tip

The industrial-grade lead screw acts as a pilot, engaging the wood immediately. This allows the bit to feed itself through the material, drastically reducing operator fatigue and making it ideal for overhead work or awkward angles.

Aggressive Triple-Spur Design

Equipped with specialized outer cutting spurs, the bit shears the wood fibers at the perimeter before the main blade removes the waste. This results in "Zero-Splinter" entry holes and significantly smoother exit holes compared to traditional flat bits.

Heat-Treated Carbon Steel

Forged from premium High-Carbon Steel, each bit undergoes a vacuum heat-treatment process to ensure a perfect balance of hardness and torsional flexibility. The black oxide finish provides superior corrosion resistance for long-term job site use.

1/4" Impact-Ready Hex Shank

The universal power hex shank is compatible with all modern impact drivers and quick-change chucks. The reinforced shank design prevents spinning and ensures maximum power transfer under high-torque conditions.

4. Professional Applications

• Electrical & Plumbing: Rapidly boring holes through studs, joists, and plates for wiring, conduit, and PEX piping.

• General Construction: Fast-paced boring in framing lumber, plywood, OSB, and softwoods.

• Cabinetry & Remodeling: Creating passages for plumbing lines and appliance wiring in finished spaces.

5. Packing & Logistics (Global Standard)

• B2B Bulk Logistics:

  • Inner Pack: Moisture-proof sleeves inside 10-set inner boxes.

  • Master Carton: Reinforced export-grade cartons palletized for international shipping.

• OEM Customization: Precision Laser Etching for brand logos and sizes directly on the bit face.

6. FAQ (Frequently Asked Questions)

Q: Why choose the threaded tip over a standard point?

A: The threaded tip eliminates the need to push the drill into the wood. The bit does the work for you, which is much faster and requires less effort, especially when drilling through thick 4x4 or 6x6 timbers.

Q: Are these bits compatible with impact drivers?

A: Yes. The 1/4" hex shank is specifically designed to handle the rapid pulses and high torque of modern impact drivers.

Q: Can these bits be resharpened?

A: Yes. While the bits stay sharp for a long time due to the HCS construction, the cutting spurs can be touched up with a small diamond file to maintain peak performance.
