Electric Hammer Chisel Head for Expansion Bolts - 40CR Alloy Steel High Hardness, Universal Square/Hex Shank, Non-Slip Concave Design Protects Threads

The Electric Hammer Chisel Head is a professional-grade tool engineered specifically for installing expansion bolts. Crafted from high-quality 40CR alloy steel and manufactured with integrated molding and high-frequency quenching processes, it delivers exceptional hardness, wear resistance, and durability—preventing breakage even under heavy use. Whether for light household tasks or demanding industrial applications, this chisel head provides powerful, efficient hammering force to streamline installation work. Its versatile design suits a wide range of scenarios, including security door/window fitting, road spike installation, and more. The concave striking surface effectively protects bolt threads from damage, ensuring smooth and reliable performance.

Key Features:

• Specialized Design: Optimized for expansion bolts, the concave head delivers direct impact without damaging screw threads. Ideal for threaded nails, speed bump spikes, road ground spikes, and thick-cap coarse steel nails.

• Universal Compatibility: Compatible with both square and hex-shank electric hammers. Square shank fits heavy-duty models (e.g., standard domestic square-shank machines), while hex shank suits lightweight hammers. Ensures powerful strikes with minimal effort.

• Premium Material: Made from 40CR alloy steel, treated with overall heat treatment and high-frequency quenching for superior hardness, abrasion resistance, and fracture resilience—reducing the need for frequent replacements.

• Robust Construction: One-piece molded structure with precision craftsmanship guarantees long-term stability and endurance.

Specifications:

• Concave Head Diameter: 18mm

• Total Length: 150mm

• Concave Depth: Approx. 5mm
  Note: Dimensions are manually measured and may have slight variances. Refer to the actual product for accuracy.

Core Advantages:

• High Strength & Durability: 40CR alloy steel and quenching technology enhance hardness and impact resistance, extending tool lifespan.

• Easy Installation: Universal shank design fits most electric hammers. Concentrated hammering force enables faster, more accurate expansion bolt placement.

• Enhanced Protection: Concave head avoids direct contact with threads, minimizing installation failures and improving workflow efficiency.

• Cost-Effective: Durable wear resistance reduces replacement costs, making it an ideal choice for professionals and DIY enthusiasts.

Applications:

• Suitable for installing expansion bolts, threaded nails, speed bump spikes, road ground spikes, and similar fixtures.

• Compatible with most domestic and imported electric hammers, including square-shank heavy-duty and hex-shank lightweight models.

Precautions:
Product dimensions are manually measured and may have minor tolerances. If high precision is required, please verify details before purchasing.
