Frequently asked questions about the Cutting discs category
What are Cutting discs?
Cutting discs are abrasive or diamond wheels for handheld and stationary tools used to cut metal, tile, concrete and stone; they come in various diameters (e.g. 125–400 mm), thicknesses and bore sizes (commonly 22.2 mm) which determine tool compatibility.
Which cutting discs fit a graver (engraving tool)?
For a graver/engraving tool use thin, small-diameter discs (typically 50–76 mm) with the correct bore size; choose discs marked for rotary tools to ensure precise, low-profile cuts and safe RPM compatibility.
Which 125 mm cutting disc to choose for an angle grinder?
For a 125 mm angle grinder pick a disc with the correct bore (typically 22.2 mm) and the right type: 1.0–1.6 mm abrasive for metal, diamond turbo/segment for tile and stone; always check the disc's max RPM rating.
How do 180 mm and 200 mm cutting discs differ?
Diameter affects cutting depth and tool compatibility: 200 mm offers deeper cuts than 180 mm but requires a grinder and guard rated for that size; always check bore size and the disc's max RPM.
Which cutting discs suit a rotary tool/drill-grinder?
Use small-diameter, thin discs (around 76 mm or less) designed for rotary/grinding tools; ensure the bore fits or use the correct adapter and choose discs rated for the tool's RPM.
Which cutting discs are best for metal?
For metal use abrasive cutting discs 1.0–1.6 mm thick marked for metal; Long Life or specialist alloy discs give cleaner cuts and longer life—always match diameter and bore to your grinder.
Are diamond cutting discs suitable for tile and concrete?
Yes. Diamond discs (turbo or segmented) are made for tile, masonry and concrete; turbo rims give cleaner cuts, segmented rims suit heavy concrete/asphalt—choose correct diameter and bore.
Can cutting discs be used on a plough (garden implement)?
Not recommended. Cutting discs are designed for high-RPM material cutting, not soil work; use purpose-made agricultural blades or replacement discs for ploughs.
How to make a cutting disc for a graver by yourself?
DIY cutting discs are unsafe: correct material, hardness and balancing are critical and a poorly made disc can shatter; it's safer to buy purpose-made thin discs for rotary tools.
How to check a cutting disc's compatibility with an angle grinder?
Check disc diameter (e.g. 125, 180 mm), bore size (commonly 22.2 mm) and the disc's max RPM to ensure they match your grinder; also verify the guard is rated for that disc size.
How do TAMO diamond discs differ from abrasive discs in use?
TAMO diamond discs (turbo, segment) are for tile, stone and concrete, giving fast clean cuts; abrasive discs suit metal and thin cuts—thinner and cheaper but wear quickly on masonry.
