Product Specification

Product Description:

Our Construction Drill Bits are high-performance masonry tools engineered to meet the rigorous demands of the global construction and renovation markets. By combining a premium High Carbon Steel body with a heavy-duty YG8C Tungsten Carbide tip, these bits are built to penetrate the toughest substrates with precision and speed. The signature Sand Blast finish provides industrial-grade corrosion resistance and a professional matte appearance, making them a preferred choice for professional distributors and hardware retailers worldwide.

Key Advantages for International Buyers:

We focus on the technical details that matter most to professional contractors and high-volume wholesalers:

• Anti-Slip Triangular (3-Flat) Shank: This specialized design locks the bit into any standard 3-jaw chuck. It prevents the bit from spinning or slipping under high torque, ensuring 100% power transfer and protecting the drill chuck from wear.

• Induction Brazed Carbide Tip: Our YG8C carbide tips are bonded using automated induction brazing at temperatures exceeding 1,100°C. This ensures the tip remains securely attached even during continuous, high-heat impact drilling in hard concrete.

• Rapid Dust Extraction: The optimized twist flute geometry is designed to pull debris out of the hole quickly. This prevents "clogging" and heat buildup, which are the primary causes of bit failure in deep-hole applications.

• Industrial Sand Blast Surface: High-pressure sand blasting creates a work-hardened surface layer that offers superior rust resistance and a professional aesthetic that appeals to industrial users.

Advanced Manufacturing Process

1. Premium Forging: High-grade High Carbon Steel is milled to precise tolerances for maximum rigidity and impact resistance.

2. CNC Flute Grinding: Flutes are ground to a precise pitch to ensure the bit remains perfectly centered, resulting in clean, round holes.

3. Vacuum Heat Treatment: Every batch undergoes controlled tempering to balance the hardness of the body with the toughness required to handle percussion forces.

4. Straightness Testing: Every drill bit is inspected for concentricity (run-out) to ensure a smooth drilling experience with zero vibration.

Packaging & Logistics:

• Retail Solutions: Individual PVC tubes, skin cards, or double-blister packs with EAN/UPC barcodes for retail readiness.

• Professional Sets: High-turnover 5-pc and 7-pc sets in customized ABS plastic cases or metal index boxes.

• OEM Branding: High-precision Laser Marking for brand logos and sizes directly on the shank.

• Export Standards: Moisture-proof inner boxes and reinforced outer cartons suitable for long-distance sea and air freight.

FAQ (Frequently Asked Questions)

Q: Can the 3-Flat (Triangular) shank fit in a standard drill?

A: Yes. It is specifically designed to fit into all standard 10mm and 13mm (3/8" and 1/2") keyed or keyless chucks, providing a much more secure grip than traditional round shanks.

Q: Is the sand-blasted finish better than a polished finish?

A: Sand blasting is superior for industrial use as it provides a harder surface "skin" and holds lubricants better, significantly improving rust resistance in humid job site conditions.

Q: Do you support custom lengths for these diameters?

A: Absolutely. We can manufacture custom lengths (e.g., 200mm to 400mm) based on your specific market demand and wholesale volume.
