The SP Air SP-7620 is a pneumatic reciprocating saw — a recipro saw — designed for cutting steel, FRP (fiberglass reinforced plastic), rubber, and resin in tight, hard-to-reach spots where a full-size air saw can't fit. SP Air built this "short" gear-type version specifically to trim the body length down without cutting into stroke speed.

The saw runs a 0.24-in. stroke at 7,500 strokes per minute, enough for clean, controlled cuts through bumper material, sheet metal, and rubber components. A safety lever prevents accidental triggering, a blade guide keeps the blade tracking straight under load, and a built-in air regulator lets you dial the tool's power at the saw itself instead of adjusting your whole air line.

What separates the SP-7620 from a basic recipro saw is the gear-driven system: instead of running the blade straight off the air motor's vane action, a gear-reduction stage smooths the stroke, which SP Air states reduces vibration and delivers a more comfortable cut. That matters most on repetitive work — bumper removal, trim cutting, exhaust hanger work — where a harsh, vibration-heavy saw wears out a hand fast.

On the job, the shortened 6.1-in. length is the real selling point: it's built for the cuts a standard-length air saw can't reach — behind a bumper cover, inside a wheel well, tight against a frame rail — without asking you to switch down to a rotary tool that cuts slower and rougher.

This is a tool for auto body techs, collision repair shops, and fabricators who regularly cut steel, rubber, and resin in cramped clearance and want a compact air saw that doesn't sacrifice cutting speed to get there.

The Recipro Saw That Fits Where the Big One Won't

The SP Air SP-7620 shortens the body without slowing the stroke, giving you a reciprocating saw that reaches into spots a standard-length air saw can't.

• Who it's for: Auto body techs and fabricators cutting steel, rubber, and resin in cramped engine bays, wheel wells, and panel gaps.
• Why it stands out: A gear-driven motor for smoother, lower-vibration cutting inside a 6.1-in. body most compact recipro saws can't match.
• Worth knowing: SP Air doesn't publish an air pressure (PSI) spec for this model on its own site, and reseller weight listings disagree with SP Air's own 1.30 lb spec — confirm both before finalizing the listing.

• How fast does the SP-7620 cut? 7,500 strokes per minute with a 0.24-in. stroke, per SP Air's spec sheet.
• What materials can it cut? Steel, FRP, rubber, and resin — SP Air specifically lists bumpers as a typical target material.
• How is the SP-7620 different from a standard-length SP Air recipro saw? It's a shortened, gear-type version built for tighter clearance — 6.1 in. overall — while keeping the same 7,500 SPM stroke speed as SP Air's longer models.
• Does the gear-driven design actually cut vibration? SP Air states the gear-driven system reduces vibration versus a direct vane-drive saw for a smoother, more comfortable cut.
