Genuine Bosch 100 mm thin bonded abrasive metal cutting disc for angle grinders — fast, clean cuts in mild steel bar, tube, sheet, and rebar on site and in the workshop.
The Bosch 4-inch (100 mm) cutting wheel is a thin bonded abrasive disc for cutting mild steel, iron, and similar ferrous metals on 100 mm angle grinders. At 1.0–1.6 mm thickness (depending on the grade), it cuts through thin-wall tube, flat bar, sheet metal, angle iron, and reinforcing bar quickly with minimal material loss in the kerf. It is the most commonly used cutting disc in steel fabrication, construction, and maintenance work across India — every workshop and site with an angle grinder keeps a stock of 100 mm cutting discs on hand.
Multi Trade Combines is an authorised Bosch dealer and stocks genuine Bosch 100 mm cutting wheels in Guwahati. In Northeast India's construction and fabrication market, 100 mm angle grinders are the single most commonly used portable power tool on every site — they cut, grind, and prepare steel daily from Guwahati to Itanagar to Aizawl. Using genuine Bosch cutting wheels — made to dimensional tolerances that ensure safe operation at maximum grinder speed — reduces the risk of disc failure and injury compared to non-branded discs that may have quality and balance inconsistencies.
Steel fabricators, civil contractors, MEP subcontractors, and site maintenance workers across Northeast India use 100 mm angle grinders and cutting discs daily. Rebar cutting, pipe trimming, bolt shortening, sheet metal cutting for roof flashing and guttering, and tacking-and-trimming in steel fabrication are all jobs done with a 100 mm angle grinder and cutting disc. The disc is a high-turnover consumable — a busy workshop site will use dozens per week.
Plumbing and HVAC contractors cutting GI pipe, copper tube, and mild steel fittings for building mechanical services in Guwahati's apartment and commercial construction market are regular buyers of 100 mm cutting discs. Electricians cutting conduit to length and trimming cable trays also use thin 100 mm discs for their clean, fast cut on thin metal.
Building contractors doing renovation and demolition work use cutting discs to cut old steel windows, grills, and structural elements. In rural Assam, repair mechanics at roadside workshops use 100 mm cutting discs for daily vehicle body, frame, and agricultural equipment repair — it is the most affordable and versatile cutting consumable available in even the smallest town market. Our Bosch range at Multi Trade Combines ensures genuine quality product for every application.

A 100 mm (4-inch) cutting wheel fits any angle grinder with a 100 mm guard and a compatible spindle speed. You must verify that the angle grinder's maximum no-load speed (RPM) does not exceed the maximum operating speed marked on the cutting wheel — typically 13,300 RPM for 100 mm wheels. Using a wheel at higher than its rated speed is dangerous and can cause the disc to burst. The wheel bore (usually 16 mm for 100 mm wheels) must also match the grinder's spindle thread. Bosch 100 mm cutting wheels are designed for Bosch and compatible angle grinders running at standard 11,000–13,300 RPM with M10 or 5/8-inch arbour threads.
Cutting wheel life is extended by: using the wheel only for its rated material (metal cut-off wheels on metal, stone wheels on masonry — never interchange), cutting with the correct angle (the wheel face perpendicular to the cut line, not angled), applying steady moderate pressure without forcing, allowing the wheel to cut at its own rate rather than forcing excess material removal per pass, and not cutting with the side of the wheel (cut-off wheels are not rated for lateral load). Store unused wheels flat in a cool, dry location — avoid stacking with the blotter labels face-down, and never use a cracked or chipped disc. One pass per cut on thin material; multiple light passes are safer for thick sections.
