Matching Spindle Threads and Bore Diameters

A proper mechanical mount prevents arbor runout and wheel vibration during high-speed operation. Disc tooling requires exact spindle or bore matching to seat squarely against the back flange of your drive unit.

For cutting and surface preparation, angle grinder accessories use either an M10/M14 spindle or matching internal arbors. Circular saw tooling in compact formats specifies a 10 mm bore, whereas dedicated wood-shaping wheels utilize a 16mm arbor hole. High-speed rotary tools run smaller shank arbors holding wheels with diameters of 40mm, 50mm, or 60mm. Always inspect machine flange drawings to verify spindle fit before ordering.

• M10/M14 spindle compatibility: Fits standard angle grinder spindles across 100/115/125 mm machine housings.
• 10 mm circular bore: Designed for specialized cutting disc sets and mini circular saws.
• 16mm arbor hole: Accommodates arc-bevel carving wheels and wood-shaping discs on standard electric grinders.

Selecting Grinding Discs and Diamond Blades by Substrate

Substrate composition dictates the choice between conventional abrasives, corundum whetstone heads, or bonded diamond edges. Running the wrong abrasive composition leads to rapid wheel glazing, burning, or premature bond breakdown.

Diamond blades sized at 105mm, 115mm, and 125mm cut dense mineral substrates like ceramic tile, porcelain, marble, and granite. Thin 1.2 mm cutting wheels made of steel deliver clean cuts in metal stock without flexing. For timber stock removal, arc-shaped bevel wheels and 125mm plane bevel grinding wheels carve wood efficiently without gumming up teeth.

• Tile, porcelain, marble, and granite: Select diamond blades sized at 105mm, 115mm, or 125mm.
• Wood carving and stock removal: Use a 100mm arc-bevel disc or a 125 mm plane bevel disc.
• Metal cutting: Utilize steel flap discs or cutting wheels with 1.2 mm thickness and 75 mm diameter.

Shank Sizing for Milling Cutters and Sanding Drum Attachments

Milling cutters, drill bits, and edge polishing attachments require rigid clamping to resist deflection under lateral load. Selecting the proper shank geometry ensures safe torque transfer and reduces chatter on CNC tables and hand-held routers.

Carbide router bits for spoilboard surfacing and slab flattening utilize an 8mm shank or 12mm 12.7mm shank to withstand radial milling forces. Carbide edges treated with an AlTiN coating withstand high temperatures during sustained passes. Rotary tool engraving and carving bits utilize a 3.175/4/6mm shank configuration. For edge profiling, a sanding drum attachment mounts directly onto an angle grinder with an M10/M14 spindle to dress wood and metal edges.

• Slab flattening and surfacing: Carbide cutters with an 8mm shank or 12mm 12.7mm shank featuring an AlTiN coating.
• Edge profiling: Sander attachment with sanding drum for 100/115/125 mm grinders.
• Drill driving: Bits with a 1/4" Hex Shank or straight High Speed Steel shank options.
