The Shinwa 45cm T-Slide II brings track-saw-style straight cuts to a handheld circular saw — no rails, clamps, or separate track system required. A rigid fence rides along the guide body on a low-friction UHPE-lined slide, so your saw glides smoothly through the entire cut instead of catching or wandering off line.
The fence adjusts forward, back, up, and down, so you can position it precisely against your material and saw before you start cutting — useful for both ripping sheet goods to width and breaking down structural timber. Built-in stabilisers keep the fence from flexing away from the blade mid-cut, which is what actually determines whether a "straight edge" guide gives you a straight cut or not.
Construction is mixed-material by design: an iron body for rigidity, an aluminium end stop, and resin slide components that keep the fence moving smoothly without wearing the guide's edge. It's built to register against a saw base with a 12mm×3mm guide slot — if you're unsure whether your saw has this, it's worth checking the base plate before ordering, or getting in touch and we can help confirm.
