4.5″ Cut Off Wheel Manufacturer | 115mm Ultra Thin

Qing Yang® manufactures 4.5 inch cut off wheels for buyers who need a compact 115mm cutting disc rather than a larger 5 inch or 125mm disc. Our core model is the T41 4.5″ cut off wheel in 115×1.6×22.2mm specification (4.5″ x 1/16″ x 7/8″), designed for precision cutting on stainless steel pipe fittings, rebar and metal profiles with 115mm angle grinders.
Compared with thicker general‑purpose cutting discs, this ultra thin 4 1/2 cut off wheel focuses on fast, cool cuts and reduced material loss, making it a practical SKU for B2B distributors supplying fabrication shops and construction contractors.

Performance advantages – 4.5 inch cut off wheel 115×1.6×22.2mm

• 1.6mm ultra-thin kerf for precise work
  The 1.6mm thickness of this 115mm cutting disc keeps the kerf narrow and heat input low, so stainless steel tube, small profiles and thin plate can be cut with less discoloration and fewer burrs compared with thicker 2.5–3.0mm wheels.
• Double fiberglass mesh for EN 12413 safety
  A double-layer glass fiber reinforced mesh is embedded into the resin bond, allowing the 4.5 inch cut off wheel to run at 80 m/s and up to 13,300 RPM while meeting EN 12413 and ANSI B7.1 safety requirements for angle grinder discs.
• T41 flat profile for maximum control
  The T41 flat geometry keeps the abrasive face level with the flanges, giving operators more lateral control on straight cuts and making this 4.5 inch cutting disc the correct choice for angle grinders that do not use depressed‑center (T42) wheels.
• Metal-focused abrasive formulation
  The aluminum oxide grain blend is tuned for metal and stainless steel cutting, helping the 4.5 inch metal cutting disc maintain consistent cutting speed on carbon steel, stainless steel pipe fittings and automotive components.

Application scenarios for 4.5 inch cut off wheels

Stainless steel pipe fittings and handrail sections
The 4.5 inch cut off wheel is widely used on 115mm angle grinders for stainless steel pipe fittings, handrail sections and thin-wall tube where a compact disc gives better access in tight spaces than 5 inch or 6 inch cutting wheels.

Rebar and steel profile cutting on site
On construction projects, 115mm cutting discs are standard for cutting rebar, angle iron and small structural profiles when mobility matters more than maximum cutting depth. The ultra-thin 1.6mm design reduces effort and sparks compared with thicker general-purpose discs.

Bolt and metal parts processing in workshops
Automotive and machinery workshops use this 4 1/2 cut off wheel to trim bolts, brackets and small metal parts, taking advantage of the high 13,300 RPM rating and fast, clean cut to keep rework to a minimum.

Tile and granite edge cutting when needed
When a contractor needs to make occasional cuts in tiles or thin granite, the 4.5 inch cutting disc can handle the job on a standard angle grinder, offering a simple solution without changing to a dedicated tile saw, while still primarily serving as a metal cut off wheel.
