Makita JN3201 6.2 Amp 10-Gauge Corded Metal Sheet Nibbler
The Makita JN3201 is a heavy-duty corded metal sheet nibbler powered by a 6.2 Amp motor delivering 1,300 strokes per minute for precise distortion-free cutting in up to 10-gauge mild steel and 13-gauge stainless steel sheet stock. Featuring a tight 4-3/4 inch inner edge cutting radius, this 7.5-pound metalworking tool easily cuts tight curves, intricate templates, and corrugated roofing sheets while directing metal chips downward away from the work surface. Engineered with double insulation, an integrated thickness gauge, and quick-change punch and die mechanisms, it provides quiet 81 dB(A) operation and continuous lock-on control for HVAC duct fabricators, roofing contractors, and auto body technicians.
Best Used For:
- HVAC Ductwork & Curved Sheet Fabrication: Trimming 10-gauge galvanized steel ducts and cutting tight 4-3/4 inch radius round cutouts without bending or distorting panel edges.
- Corrugated Metal Roofing & Siding Installation: Cutting angled pitch lines and ridgelines through corrugated panel profiles while discharging metal chips underneath the cut line.
- Auto Body & Stainless Steel Equipment Repair: Following complex layout lines across 13-gauge stainless steel sheets and structural body panels with a direct, unobstructed line of sight.
Key Performance & Safety Features
- Powerful 6.2 Amp Industrial Motor: Drives the punch mechanism at 1,300 SPM to slice through heavy sheet metals without binding or stalling.
- Tight 4-3/4 Inch Cutting Radius: Enables precision pattern cutting with an inner edge radius of 4-3/4 inches and outer edge radius of 5-1/16 inches.
- Downward Metal Chip Waste Disposal: Ejects waste chips underneath the workpiece to prevent scratching or damaging finished metal coatings.
- Built-In Material Thickness Gauge: Integrated measuring slot on the die neck allows rapid verification of sheet metal gauge before starting cuts.
- Quiet 81 dB(A) Noise Level Rating: Low noise motor housing design minimizes workplace decibel levels during extended cutting tasks.
- Fast Punch & Die Replacement: Simple mechanical locking system allows quick access for field replacement of worn punches and dies to minimize project downtime.
