Description
Portable Rail Saw for Cutting Granite, Quartzite & Porcelain Slabs On-Site
The Achilli TSA is an Italian-built portable rail saw for straight cutting of granite, quartzite, marble, engineered stone, and porcelain slabs — in the shop or on the job site. Set the rails directly on the slab, drop the 6-bearing cutting head on the track, connect water with one hand, and make full-length rip cuts up to 13 feet without moving the material to a bridge saw.
Where most rail saws on the market are built around converted angle-grinder heads, the TSA uses a purpose-built 2.2 kW (3 HP) single-phase induction motor on a sandblasted, epoxy powder coated steel frame — industrial machine construction from Achilli, an Italian manufacturer of stone cutting machinery since 1963. And it does it at well under half the price of the best-known rail saw systems, with rails included in kit configurations.
Why Fabricators Choose the TSA
True 13 ft Single Rail — Full Slab Rips in One Pass
The TSA is available with a one-piece 13 ft (4000 mm) rail — no joints, no alignment seams across the length of a full slab. A one-piece 8 ft (2500 mm) rail and a modular 12 ft kit (three 4 ft locking sections) are also available, so you can match the rail to the work: countertop rips, cladding panels, island slabs, and waterfall-length material.
6-Bearing Head — No Lateral Play, No Wandering Cut
The cutting head travels on six 32 mm precision bearings. The result is smooth, consistent feed with zero lateral movement — the straight, clean edge you'd expect from a shop bridge saw, produced wherever the stone is sitting.
3 HP Induction Motor — Built for Continuous Wet Cutting
The 2.2 kW single-phase motor runs 12"–14" (300–350 mm) diamond blades and is designed for sustained wet cutting, not intermittent grinder duty cycles. No 3-phase supply required — the TSA runs on any 230V single-phase circuit or a jobsite generator.
One-Hand Water Connection
Quick-connect fitting gets blade cooling running in seconds. No fumbling with hose fittings mid-setup on an install.
Tool-Free Depth Adjustment
Cutting depth is set by hand wheel — adjust between cuts in seconds, no wrenches, no re-clamping.
Industrial Frame, Wet-Environment Finish
Steel frame, sandblasted and epoxy powder coated for daily wet cutting. Galvanized finish available on request for maximum corrosion resistance.

What Does the Achilli TSA Cut?
- Granite — including hard 3 cm material
- Quartzite
- Quartz and engineered stone
- Marble and natural stone slabs
- Porcelain slabs and ultra-compact surfaces (Dekton, Neolith, Laminam) with the appropriate blade
- Stone cladding and wall panels
Rail Saw Applications
- On-site rip cuts on full-size granite and quartz countertop slabs
- Cutting slabs to size at installation — no return trip to the shop
- Straight cuts on cladding and large-format wall panel stone
- Overflow cutting capacity for shops where the bridge saw is the bottleneck
- Remodel and commercial work where material can't be transported
How the TSA Compares to Other Rail Saws
Most portable rail saws for granite are priced between $4,700 and $5,500 for the saw alone, with rails sold separately — and many are built around modified angle-grinder motors. The Achilli TSA delivers a purpose-built induction motor, a genuine one-piece 13 ft rail option, and Italian industrial machine construction at $2,429 for the saw unit. Add the rail configuration that fits your work and you're still well under the price of the saw alone from the best-known competitors.
If your work is mostly straight rips — sizing slabs, cutting countertops to length, panel work — the TSA does exactly what the expensive systems do, at roughly half the invested cost.
Frequently Asked Questions
What is a rail saw and how is it different from a bridge saw?
A rail saw is a portable, track-guided stone saw: the rails sit directly on the slab and guide the cutting head for perfectly straight cuts. A bridge saw is a fixed shop machine. Rail saws like the TSA give you bridge-saw-straight rip cuts anywhere — at a fraction of the cost and with no material handling back to the shop.
Frequently Asked Questions
What is the maximum cut length with the TSA?
With the single 13 ft (4000 mm) rail, the TSA can make straight cuts up to approximately 13 ft in a single pass. The 3-rail 12 ft kit provides similar reach with a modular setup.
Does it require 3-phase power?
No. The TSA runs on 230V single-phase — standard site power. No 3-phase supply required.
Can I buy the saw without rails and add rails later?
Yes. The saw unit is available without rails, and rail sets (8 ft, 13 ft, or 3- 4 ft sections=12 ft kit) are available separately to match your cutting requirements.
What blade sizes does it accept?
300 to 350 mm (12" to 14") diameter blades with a 25.4 mm (1") bore.
How does the water cooling connect?
Via a one-hand quick-connect fitting — fast to attach and detach on-site without tools.
Is the frame durable enough for regular job-site use?
Yes. The steel frame is sandblasted and finished with epoxy powder coating for wet cutting durability. A galvanized finish is available on request for additional corrosion resistance in demanding environments.
