TRANSPARENT MANUFACTURING:
FROM RAW STEEL TO GLOBAL DELIVERY
See exactly how your wholesale orders are forged, inspected, and shipped.
RAW MATERIAL SOURCING & INSPECTION
The Process: We begin by sourcing premium-grade High Carbon Steel (65Mn and 40Cr) strictly from certified suppliers.
The Control: Before entering production, every batch undergoes strict spectral analysis and physical inspection. We verify material purity and metallurgical integrity to ensure no flaws exist at the foundational level.
CUTTING & CNC MACHINING
The Process: The raw steel bars are precision-cut to your specified lengths. Next, they move to our advanced CNC lathes, where the complex shank geometries (Hex, SDS-Plus) are machined.
The Control: CNC automation guarantees 100% concentricity and strict dimensional tolerances, ensuring zero wobble when the bit is used in power tools.
FLUTE MILLING & THREADING
The Process: Automated heavy-duty milling machines carve out the deep, smooth spirals and the aggressive self-feeding screw point.
The Control: We meticulously monitor the cutting angles to ensure the spurs are razor-sharp. This is the secret behind our drill bits' rapid chip removal and smooth hole drilling capabilities.
SALT BATH HEAT TREATMENT
The Process: Salt bath heat treatment involves submerging tools in molten salt to achieve perfectly uniform heating while completely preventing surface oxidation.
The Control: This advanced process guarantees the exceptional hardness, superior toughness, and strict batch consistency required for premium industrial cutting tools.
SURFACE FINISHING & 100% QUALITY ASSURANCE
The Process: Bits receive surface treatments (Black Oxide, Titanium, or PTFE) for rust prevention. Then, they enter the final QA phase.
The Control: Our inspectors check dimensional accuracy, perform Rockwell hardness tests, and conduct destructive drilling tests on solid hardwoods. Only flaw-free products pass this stage.
CUSTOM PACKAGING & LOGISTICS
The Process: Approved bits are packed according to your exact OEM specifications (blister cards, plastic tubes, wooden cases) using moisture-proof materials.
The Control: Fully palletized orders are loaded into containers. Our experienced logistics team handles all customs documentation, ensuring your bulk orders are shipped on time, meeting our strict 45-day delivery promise.

Frequently Asked Questions
Expert answers to help you select, use, and maintain your wood auger drill bits.
How to Sharpen Wood Auger Drill Bits?
Following 3 quick steps using an auger bit file:
- File the main cutting edges upward from the inside.
- Lightly file the inside of the cutting spurs.
- Never file the outside of the spurs, as this reduces diameter and ruins it.
How to Sharpen an Auger Drill Bit safely?
Always use a manual hand file, not an electric grinder. A grinder will melt or ruin the delicate screw point. If a small metal burr forms after filing, simply drill a test hole in scrap wood to naturally break it off.
Are Auger Bits Best when Drilling through Wood?
Yes, especially for deep and large holes. The screw tip automatically pulls the bit into the wood (saving your effort), while the deep flutes quickly clear out wood chips to prevent jamming and overheating.
Can I Use an Auger Bit in a Power Drill?
Yes. Our bits feature Hex, Quick-Change, or SDS Plus shanks that fit most power tools perfectly. Just remember to use a low speed (500 - 600 RPM) for better control and to protect the cutting edge.
What is the Longest Flexible Auger Drill Bit?
Flexible auger bits (used for wire installation) can reach up to 72 inches (6 feet). However, for rigid, heavy-duty wood drilling, Tenyu Tools manufactures extra-long auger bits up to 600mm (approx. 24 inches).
What are Auger Drill Bits Used For?
They are heavy-duty tools designed for drilling deep, clean holes.
- Wood Auger Bits: Used for timber framing, furniture joinery, and heavy construction.
- Earth Auger Bits: Used in landscaping to drill into soil for fence posts and planting.
