Mega Coarse Diamonds

Mega Coarse diamonds exceed the standard ISO grit ladder, engineered for the heaviest stock removal in Busch's DiaTwister line before stepping down to a standard coarse or super coarse grit. Every diamond in this collection carries "Mega Coarse Grit" directly in its product tag, available in HP shank.

Reach for Mega Coarse when you need to remove the most material the fastest — gross reduction of acrylic, resin, or model material during model making, orthodontic appliance adjustment, and initial plastics shaping — before finishing with a standard coarse or finer grit.

FAQ

What makes Mega Coarse different from Super Coarse (black ring)? Mega Coarse sits a step above the standard color-coded ladder — it's Busch's most aggressive DiaTwister grit, designed for even faster stock removal than a standard black-ring super coarse diamond.

Is Mega Coarse part of the standard ring-color system? No — Mega Coarse is a DiaTwister-specific grit without a ring-color designation; look for "Mega Coarse Grit" in the product title and tag instead.

Where are these diamonds made? Every instrument in this collection is manufactured by Busch & Co. in Engelskirchen, Germany — an ISO 13485-certified specialist in rotary precision instruments since 1905 — and ships fast from our US warehouse.
