Power Tool Accessories

32 products available

Industrial operations depend on power tool attachments to handle surfacing, profiling, cutting, and stock removal across active job sites and industrial shop floors. Compel supplies trade contractors and machining facilities with high-performance tooling built for heavy production cycles. Our inventory covers angle grinder accessories, circular saw blades, carbide end mills, and rotary tooling.

You can source grinding discs, diamond cutting wheels, flap discs, and dedicated wood-shaping cutters suited for demanding metalworking and woodworking runs. We stock precision drill bits, center drill bits, slab flattening bits with AlTiN coatings, and specialized drum setups. Every accessory matches standard workshop spindles and machine chucks. Compel provides verified technical specifications and dependable batch consistency with direct trade ordering. Your crews maintain steady production schedules without unexpected tooling downtime or premature abrasive wear on the line.

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.

Buying guide

Choosing Power Tool Accessories

How do I confirm compatibility for angle grinder accessories across different tool sizes?
Check spindle thread and guard clearance on your machine. Many angle grinder accessories mount directly to an M10/M14 spindle, while disc sanders and wheels require a 16mm arbor or standard 100/115/125 mm guard clearance. Match the rated disc diameter, such as 115mm or 125mm, directly to your machine guard rating.
When should I use diamond blades instead of abrasive grinding discs for tile and masonry?
Diamond blades are required when cutting or grinding hard mineral substrates including ceramic tile, porcelain, marble, and granite. Standard grinding discs work for general steel and metal cutting, but they glaze or wear rapidly against dense stone. Compel supplies diamond wheels in 105mm, 115mm, and 125mm diameter for masonry cuts.
Can I mount a sanding drum attachment on an angle grinder for metal edge polishing?
Yes, dedicated sander attachment setups with a sanding drum fit an M10/M14 spindle on grinders rated at 100/115/125 mm. This setup allows controlled edge polishing and smoothing on wood and metal workpieces without requiring a separate bench sander. Check the spindle size of your angle grinder before fitting the drum attachment.
Which shank diameter should I specify for heavy routing and spoilboard surfacing?
Select an 8mm shank or 12mm 12.7mm shank for high-load slab flattening and spoilboard surfacing. Larger shanks provide greater rigidity and minimize deflection during deep planing passes in solid wood. For light engraving, trimming, or rotary work, tools with a 3.175/4/6mm shank or 1/4" Hex Shank configuration provide appropriate maneuverability.
What coating is recommended on power tool attachments for high-heat cutting?
Carbide bits with an AlTiN coating provide superior oxidation resistance during high-friction operations like surfacing and dry milling. TiN and TIAIN coatings also increase surface hardness on High Speed Steel drill bits and milling cutters. For standard woodworking and soft stock, uncoated carbide or titanium coated tools remain practical options.
