Comprehensive Data Attributes Sheet

What Makes It Better (Internal Tech & Materials)

• Patented Dual-Piston Balancer: Two internal cylinders operate in exact structural opposition. The physical momentum of one cylinder cancels out the recoil forces of the second, resulting in ultra-low vibration.

• Impact-Resistant Composite Body: Clad in structural composite nylon that withstands drops on commercial concrete floors and resists industrial solvents.

• Built-In Regulator Dial: Includes a recess-mounted air control dial near the inlet to adjust stroke frequency dynamically on delicate materials.

Industrial Applications & Workflows

• HVAC Sheet Fabrication: Punch-cutting clean intake square lines inside existing galvanized steel wall ducts.

• Automotive Frame Modifications: Cutting away bent high-strength panel sections during heavy collision repairs.

• Fiberglass Profiling: Clean cutting of marine hull shapes and fiberglass automotive enclosures without tearing gel coats.

What Our Customers Are Saying

⭐⭐⭐⭐⭐ "The Gold Standard for Body Shops"

"I've used many air saws in my 20 years as a panel beater, but nothing beats the SI-4700B. It’s light, fast, and doesn't rattle your teeth out. The Japanese build quality is obvious from the first cut." — Mark D., Automotive Fabricator

⭐⭐⭐⭐⭐ "Worth Every Penny."

"You can buy a cheaper saw, but you'll buy it three times before this one even needs a drop of oil. The precision on curves is unmatched." — Steve G., Metal Fabricator

Frequently Asked Questions (FAQ)

1. What thickness of steel plate can this saw handle?

   • Answer: It cuts through structural mild carbon steel up to 1/8" (3.2mm) thick. For aluminum and brass sheets, it can easily handle up to 3/16" (4.8mm).

2. Does this air saw accept standard T-shank jig saw blades?

   • Answer: The SI-4700B is designed for standard 1/2" universal pneumatic saw blades. While some T-shank blades may fit the collet, we recommend using dedicated pneumatic blades for maximum safety and cutting efficiency.

3. Why is my saw losing cutting speed during long straight cuts?

   • Answer: This is usually caused by system moisture freezing the internal dual-piston assembly, or a drop in air pressure. Ensure your line is dry by deploying a Tend Water Trap Filter.

Q: Can this saw cut through stainless steel?

A: Yes. While optimized for 3mm mild steel, with the correct high-quality Bi-Metal blade, it can efficiently cut through stainless steel and aluminum panels.

Q: Does it come with blades?

A: Yes, the SI-4700B typically includes a starter set of blades, but we recommend stocking up on Shinano Genuine Blades for the best performance.

Q: What is the recommended air pressure?

A: For optimal performance and tool longevity, operate at 90 PSI (6.2 bar).

Q: How do I maintain this tool?

A: Being a precision Japanese tool, it requires daily oiling. Just 2-3 drops of pneumatic tool oil in the air inlet before use will keep it running for a decade.
