This Coarse (Blue) Thin Flat Profile Disc Part #10087 is a part of the Nick Agar Signature Series. It is an All Surface 3 Edge Tungsten Carbide Disc, has a 2” (50mm) diameter x 10mm center x 5/32" (4mm) thickness and fits the Merlin2® miniature angle grinder. If using this disc with the Arbortech Mini Carver ...it MUST be used with the brass insert that comes with the tungsten mini blade. Brass inserts and mounting bolts can be ordered as a package of replacement parts.
Use for sharpening the high speed steel blades that come with the Mini Grinder. Tip from Pop: File the teeth straight across ...do not angle them! Also keep force on the upper edge of the teeth so as to sharpen the 'hook' or you will get burning when carving.
