1. Technical Specifications: The Power Behind SMT-6326

Understanding the raw power of your tool helps you choose the right bits and materials.

Drilling Capacities:

• Concrete/Masonry: Up to 26mm (Ideal for anchor bolts and conduits).
• Steel: Up to 13mm (For structural steel and rebar).
• Wood: Up to 42mm (Large-bore drilling).

2. Step-by-Step: How to Use the SMT-6326

A. Setting Up the SDS-Plus System

The SMT-6326 uses the SDS-Plus chuck, which ensures the bit doesn’t slip during high-impact tasks.

1. Grease the Bit: Apply a small amount of lithium grease to the bit shank to prevent friction inside the chuck.
2. Locking: Pull back the chuck collar, insert the bit, and twist until it clicks.
3. Verification: Always tug the bit to ensure it is locked before starting the motor.

B. Choosing Your Mode

• Hammer Drilling: Use this for concrete and stone. The 7J impact energy combined with 900 RPM rotation makes quick work of hard surfaces.
• Chiseling (Hammer Only): Perfect for removing old tiles or breaking small concrete sections. The bit provides the 4,000 BPM impact without rotating.

C. Handling the 4.5kg Weight

Because this tool weighs 4.5kg, ergonomics are key:

• Use the 360° auxiliary handle to distribute weight between both hands.
• Let the 7.0 Joules of force do the work. Do not push hard; the pneumatic piston requires only light guiding pressure to operate efficiently.

3. Maintenance for Industrial Longevity

The SMT-6326 is built for heavy use, but it requires care to maintain its 1050W efficiency:

• Dust Management: Concrete dust is abrasive. Use a vacuum or blow out the motor vents after every use to prevent overheating.
• Carbon Brush Check: Regularly inspect the brushes through the side access ports. If you see excessive sparking or lose power, replace them immediately.
• Cooling Cycles: If the gearbox feels hot during continuous drilling, run the tool at no-load (in the air) for 30 seconds to allow the internal fan to cool the motor.

4. Why Choose the SMT-6326? (Key Advantages)

1. Industrial Force: Most standard rotary hammers offer 2-3 Joules. The SMT-6326 offers 7 Joules, making it twice as fast in hard concrete.
2. Variable Impact: The 0–4,000 BPM range allows you to start slowly for precision and increase power for speed.
3. Durability: At 4.5kg, the tool features a more robust metal gearbox than lightweight plastic alternatives.

Buying Information (Pakistan)
