Product Specification

Product Overview

Our Construction-Grade SDS Masonry Drill Bits are heavy-duty percussion tools designed for high-intensity drilling in reinforced concrete, solid brick, and natural stone. Featuring a proprietary Sand-Blasted Anti-Rust Finish, these bits are built to withstand the harshest job site conditions—from the high-humidity environments of the Middle East to the extreme sub-zero temperatures of Russia.

By combining a high-flexibility alloy body with an ultra-hard carbide cutting head, this series provides the reliability required for structural anchoring and industrial installations.

Technical Specifications & Dimension Chart

We provide a comprehensive range of SDS Plus and SDS Max configurations. Each bit is precision-machined to ensure 100% concentricity and high-impact energy transfer.

Engineering Excellence & Key Advantages

Industrial Sand-Blasted Anti-Rust Finish

Unlike standard polished bits, our bits undergo a high-pressure sand-blasting process. This creates a work-hardened surface "skin" that is significantly more resistant to oxidation and surface corrosion. The matte finish also provides a higher friction surface for the chuck, ensuring a more secure grip and reducing energy loss.

Premium YG8C Tungsten Carbide Tip

The cutting head is equipped with high-density YG8C Carbide, vacuum-brazed at temperatures exceeding 1,100°C. This ensures the tip remains sharp and seated even during "red-hot" continuous drilling in high-PSI concrete.

High-Volume U-Flute Geometry

The precision-ground U-Double Flute acts as a high-speed conveyor for dust. By evacuating debris instantly, it prevents the bit from "choking" in deep holes, reducing friction heat and extending the tool's lifespan by up to 30%.

Professional Applications

• Infrastructure: Bridge reinforcement, tunneling, and high-rise structural anchoring.

• HVAC & Plumbing: Precise 12mm to 16mm holes for conduits and pipe through-wall access.

• Renovation: Effortless penetration of aged concrete panels and dense silicate brickwork.

• Stone Masonry: Smooth drilling in granite, basalt, and limestone.

Packaging & Global Logistics

• Retail Ready: Available in individual PVC hanging tubes or professional 5-piece to 10-piece sets in ABS plastic cases.

• Bulk Supply: Moisture-proof inner boxes and reinforced outer cartons palletized for long-distance sea and rail freight.

• OEM Branding: We offer high-definition Laser Marking for brand logos and localized technical specs (English/Russian/Arabic) directly on the shank.

FAQ (Frequently Asked Questions)

Q1: Why is the sand-blasted finish preferred over a shiny chrome finish?

A1: Sand-blasting is an industrial treatment that increases surface durability and prevents the flaking or peeling often seen with chrome plating under high impact. It is specifically designed for the professional construction market.

Q2: Are these bits compatible with all rotary hammer brands?

A2: Yes, our SDS Plus and SDS Max shanks are manufactured to strict international standards, ensuring a perfect fit with all major global rotary hammer brands.

Q3: How do you ensure the quality of the carbide tips?

A3: Every batch undergoes a destructive "pull-out" test and a hardness verification to ensure the YG8C carbide meets the required HRC 89-91 rating.

Q4: Can these bits withstand the extreme cold in Russia?

A4: Absolutely. We use a proprietary 40Cr Alloy Steel that has been vacuum-tempered to maintain its toughness and prevent brittleness in sub-zero site conditions.
