Bosch 125 mm tungsten carbide tipped cutting wheel — greater depth per pass for thick timber, wide aluminium profiles, and sheet materials on 5-inch angle grinders.
The Bosch TCT Wheel 5 inch (125 mm) is a tungsten carbide tipped circular cutting blade designed for 5-inch angle grinders for cutting timber, plywood, MDF, fibre cement sheet, and non-ferrous metal sections including aluminium and copper profiles. It is the larger-diameter equivalent of the 4-inch TCT wheel, providing a greater cutting depth per pass to handle thicker material. TCT cutting blades deliver dramatically longer service life and cleaner cuts than abrasive discs on all wood, panel, and non-ferrous material cutting applications, and are the standard accessory for interior fit-out, carpentry, and aluminium fabrication work.
As an authorised Bosch dealer in Guwahati, Multi Trade Combines stocks the complete Bosch accessories range including both 4-inch and 5-inch TCT wheels alongside abrasive discs, grinding wheels, and diamond blades. The 5-inch TCT wheel is well suited to the Northeast India construction and fit-out sector where 125 mm angle grinders are widely used as the standard general-purpose site tool — the same machine that grinds metal during structural work can be fitted with a TCT blade for woodworking and panel cutting duties on the same site.
Carpentry and interior fit-out contractors working on residential and commercial projects in Guwahati's growing real estate market use the 5-inch TCT wheel for cutting door frames, stud partition timber, ceiling battens, and sheet materials. Contractors fitting aluminium composite panel (ACP) cladding on commercial building facades cut the ACP sheets to size using TCT blades on angle grinders — the TCT blade produces a straight, clean edge without the rough burring of abrasive cutting.
Aluminium window and door fabricators in Guwahati and Dibrugarh producing aluminium extrusion window frames and grille work use the 5-inch TCT blade for cross-cutting extrusion sections. It produces a cleaner cut end than abrasive methods, reducing the deburring time before assembly and powder-coat finishing. Tea estate maintenance teams use it for timber maintenance work — cutting decking boards, fence rails, and building repair timber to length on estate premises.
The Bosch TCT Wheel 5 inch pairs naturally with the Bosch GWS 750-125 or GWS 850 CE 125 mm angle grinders, and with the 4-inch TCT wheel where both grinder sizes are used on the same project. All available from Multi Trade Combines, authorised Bosch dealer, AT Road, Guwahati. Shipped across Northeast India.

The Bosch TCT Wheel 5 inch (125 mm) is designed for 5-inch (125 mm) angle grinders, which are larger, more powerful, and heavier-duty than 4-inch (100 mm) models. The 5-inch TCT wheel has a larger blade diameter, which gives a deeper cutting depth per pass and allows it to cut thicker material sections in a single pass — typically 30 to 40 mm cutting depth for the 5-inch versus 20 to 25 mm for the 4-inch. This makes the 5-inch TCT wheel the choice for cutting thicker timber sections, wider aluminium profiles, plywood stacks, and engineered boards on site. The 5-inch grinder also has higher motor power (typically 1200–1400 W versus 750–900 W for 4-inch) which sustains the cutting speed better on dense hardwood and thick aluminium. Choose the blade to match the grinder and the material depth.
Yes, provided the grinder is specifically rated for a 125 mm diameter disc and the blade's maximum rated RPM equals or exceeds the grinder's no-load RPM. The Bosch 5-inch TCT blade is rated for use on 125 mm angle grinders only — it must not be fitted to a 4-inch (100 mm) grinder (wrong arbour diameter and size), a 7-inch (180 mm) grinder (the larger machine spins the smaller blade dangerously fast), or any grinder without a matching blade guard fitted. Always use the disc guard, set the maximum cutting depth via the guard position, and never remove or disable the guard. TCT blades rotating at grinder speed are capable of serious injury if the blade contacts a hard object and kicks back — correct machine and blade matching is essential.
