# SCM Nova SI 4S Sliding Table Saw

## SCM Nova SI 4S Sliding Table Saw

Most shops that want a slider run out of floor space before they run out of budget. A machine built on a 3,200 mm carriage has a footprint over 23 feet long, and plenty of buildings simply do not have that wall. The SI 4S is SCM’s answer: the same saw unit, motor, and blade capacity as the full-size Nova SI 4, on a 1,600 mm carriage that fits where the long machines cannot.

### The Same Saw, in Less Room

As configured here, the SI 4S matches the [Nova SI 4](/product/scm-nova-si-4-sliding-table-saw/) on every number that decides what you can cut:

- **8 HP three-phase main motor**, the same as the SI 4
- **400 mm (15.75 in) blade capacity** with the 400 mm blade kit included at this price
- **140 mm (5.5 in) of cut** at 90 degrees, 99 mm (3.9 in) at 46 degrees
- **1,040 x 630 mm cast-iron worktable**, the full-size table
- **Independent powered scoring unit** for clean undersides on veneered panels

What you give up is stroke. The squaring capacity is 1,600 mm rather than the 3,200 mm of the bigger machines, so a full 8-foot sheet cannot be crosscut in one pass on the carriage. For a shop cutting cabinet parts, solid stock and half sheets, that is often no constraint at all, and the machine occupies roughly four meters of length instead of the seven a 3,200 mm carriage demands.

### The Carriage

The carriage is the same design SCM uses across the Nova range: closed reticular geometry with steel guides held by SCM’s own mechanical fixing method, and it locks at any point along its travel. SCM guarantees the carriage sliding system for ten years.

### Blade and Cut

The blade tilts from 90 to 46 degrees and turns at 3,700 rpm. Both the lifting and tilting mechanisms are cast iron: the former runs on ground round slideways, and the latter on crescent-shaped rotation sectors. So adjustments stay accurate as the machine accumulates hours. Rip capacity at the parallel fence is 50 inches. SCM’s Thundercut app, activated by a QR code that ships with the machine, optimizes cutting lists and walks the operator through the sequence.

### When to Step Up Instead

If you regularly crosscut full sheets on the carriage, the [SI 4](/product/scm-nova-si-4-sliding-table-saw/) with its 3,200 mm stroke is the machine you actually want, and it costs about $2,000 more. The SI 4S is the right answer when floor space, not capability, is the binding constraint.
