Bosch 100 mm tungsten carbide tipped cutting wheel — long-lasting TCT blade for clean cuts in wood, plywood, aluminium, and fibre cement on 4-inch grinders.
The Bosch TCT Wheel 4 inch is a 100 mm tungsten carbide tipped circular cutting blade designed to mount on a 4-inch angle grinder or compact circular saw for cutting wood, plywood, MDF, fibre cement board, and non-ferrous metals such as aluminium sections and profiles. Unlike bonded abrasive discs that grind through material and wear down rapidly, the TCT blade uses durable tungsten carbide tooth inserts that slice cleanly through the workpiece, producing a smooth cut edge with minimal chipping and far lower dust compared to abrasive cutting.
Multi Trade Combines is an authorised Bosch dealer in Guwahati, stocking the full range of Bosch power tool accessories including TCT blades, grinding discs, and cutting wheels. The 4 inch TCT Wheel is popular with carpenters, false-ceiling contractors, fit-out and interior finishing crews, and aluminium fabricators across Assam and Northeast India. It is an essential accessory for any site or workshop using a 4-inch angle grinder for woodwork or non-ferrous section cutting alongside metal grinding duties.
Interior fit-out and false ceiling contractors are the largest single-use group. A 4 inch angle grinder fitted with a Bosch TCT blade cuts gypsum board, MDF panels, and plywood trim boards cleanly and quickly on commercial and residential projects in Guwahati's rapidly growing residential and commercial construction sector — projects in Beltola, Hengerabari, Dispur, and Narengi where apartment and commercial interior finishing work is constant.
Aluminium fabrication shops making windows, doors, and curtain wall sections use the TCT wheel to cross-cut aluminium extrusions cleanly without the burring and heat generated by abrasive methods. Fibre cement board (Asbestos-free flat sheet) cladding contractors use TCT blades to cut sheets to fit around structural columns and openings. Furniture makers and cabinet workshops in Guwahati and Dibrugarh use the 4 inch TCT for detailed panel cutting and trim work.
The Bosch TCT Wheel 4 inch pairs with the angle grinder itself — Bosch GWS 6-100 or GWS 750-100 are the standard 4-inch models — and with Bosch grinding discs for edge dressing after cutting. Both are available from our Power Tools counter at Multi Trade Combines, AT Road, Guwahati.

TCT stands for Tungsten Carbide Tipped — the cutting teeth on the blade carry brazed tungsten carbide inserts rather than hardened steel alone. Tungsten carbide is far harder than steel and maintains its edge at the heat generated during cutting. The Bosch TCT Wheel 4 inch is suitable for cutting softwood, hardwood, plywood, fibre cement board, aluminium, and some non-ferrous composite materials. It is not suitable for ferrous metals (iron, steel) or masonry — those require abrasive cut-off wheels. Always verify the material compatibility on the blade label before use and match the machine speed (RPM) to the blade's maximum speed rating.
A quality Bosch TCT blade in wood cutting applications typically lasts 50 to 200 times longer than a bonded abrasive disc on the same material. The abrasive disc wears down with each use and requires replacement every few cuts in hard materials, whereas the TCT blade retains its edge across thousands of linear metres of cutting before the carbide tips need resharpening or replacement. TCT blades can be resharpened by a specialist tool sharpening service, extending their life further. In the long run, a TCT blade has a lower cost per metre of cut than abrasive discs, particularly for contractors doing high-volume wood panel or aluminium cutting work.
