Industrial-grade 1A1R Slotted/Gulleted Sintered Metal Bond Diamond Cut-Off Wheel. Proudly Made in the USA, this heavy-duty blade features small, precision-engineered 3/16" U-slots (gullets) along the periphery and a high diamond concentration. This hybrid design gives you the ultra-smooth, chip-free finish of a continuous rim combined with the superior cooling and slurry-flushing efficiency of a segmented blade.
This item is New Old Stock (NOS)—it has never been used or mounted, featuring a 100% fresh, intact diamond cutting edge.
Note: We have a total of 3 identical wheels available in this listing. If you need more than one, simply adjust your quantity at checkout.

Outside Diameter: 10" (254mm)
Diamond Thickness (Kerf): 0.052"
Arbor Hole (ID): 5/8" (0.625")
Diamond Depth: 5 mm (Generous depth for an extended service life)
Grit Size: 60/80 Grit (Medium-coarse for fast, aggressive cutting without heavy chipping)
Bond Type: Sintered Metal Bond
Concentration: High Diamond Concentration
Origin: Made in the USA
New Old Stock (NOS): Brand new and entirely unused. The diamond matrix edge is completely fresh.
Storage Wear & Patina: Due to long-term industrial shelf storage and handling, the bronze/copper-finished steel core exhibits surface scratches, minor surface debris, and a mottled storage patina/surface oxidation.
Multi-Item Variation: Because there are 3 wheels available, the exact appearance of the surface patina/discoloration may vary slightly from wheel to wheel. The photos/video show the typical cosmetic condition.
Performance: These imperfections are strictly cosmetic and surface-level. They will not affect the wheel’s structural integrity, balance, or cutting performance.
Engineered with a 60/80 grit profile and a high diamond concentration, this gulleted wheel is ideal for processing hard, dense, and abrasive materials, including:
Advanced engineering and technical ceramics (Alumina, Zirconia, Silicon Carbide)
Quartz, thick industrial glass, and fused silica
Dense geological core samples, mineral specimens, and petrographic sections
Fine lapidary materials and hard gemstones (agate, jasper, jade, petrified wood)
Ferrites, dense carbon-graphite composites, and magnetic components
Featuring a standard 5/8" arbor, this versatile 10" wheel is designed to work with a variety of laboratory, lapidary, and industrial machinery:
Precision metallurgical sectioning saws and abrasive cut-off machines (e.g., Buehler, Struers, Allied High Tech, LECO)
Industrial lapidary trim saws and high-end masonry/tile saws rated for 10" blades
Toolroom surface grinders configured for wet cutting operations
High-precision production slicing and dicing equipment
Operational Tip: Sintered metal bond diamond wheels perform best and last longest when used with an appropriate coolant/lubricating fluid (wet cutting). The gullets on this rim are specifically designed to draw fluid into the cut area and flush out slurry.
Fast shipping. Please review the high-resolution photos carefully to inspect the cosmetic condition. If you have any questions, feel free to reach out!
