It uses Armored Synthetic Diamond (ASD) abrasive bonded in a resinoid matrix, delivering consistent cut rates across both wet and dry operations. At 150 grit, the wheel falls in the very fine grade range, making it well suited for applications that require both roughing and finishing in a single setup. The specification designation ASD150-R75B99-1\/4 identifies the abrasive type, grit, hardness, concentration, bond, and superabrasive depth. Licensed tradespeople and toolroom machinists working with carbide, ceramics, and other superhard materials will find this wheel a reliable production tool.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for surface grinding operations on bench grinders, surface grinders, and compatible rotary grinding machines that accept a 1-1\/4 inch arbor bore. It is appropriate for both roughing stock removal and finish-pass work on hard and superhard workpieces including cemented carbide tooling, ceramic components, and hardened steel. The no-recess, flat-face Type 1A1 form fits standard surface grinding machine spindles. Both wet coolant and dry grinding setups are supported by the resinoid bond system.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eArmored Synthetic Diamond (ASD) abrasive for extended wheel life on superhard materials\u003c\/li\u003e\n\u003cli\u003e150 grit very fine grade supports roughing and finishing in a single wheel\u003c\/li\u003e\n\u003cli\u003eResinoid bond provides consistent stock removal with good form retention\u003c\/li\u003e\n\u003cli\u003eSupports wet and dry operation for flexibility across shop environments\u003c\/li\u003e\n\u003cli\u003eSoft hardness rating (R) and 75 concentration for controlled, free-cutting action\u003c\/li\u003e\n\u003cli\u003eNo-recess Type 1A1 flat form fits standard surface grinder spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or production wheel for surface grinders and bench grinding machines with a 1-1\/4 inch arbor bore accepting a Type 1A1 straight wheel form.
