Alpha® Quad Adapter — Brass (M10-1.25 / M14-2)
The Alpha® Quad Adapter is engineered specifically for flush-cutting blades with four mounting holes. Machined from high-quality solid brass — safer and far longer-lasting than aluminum equivalents — the adapter ships with four screws and two nylon lock nuts, mounts in seconds, and is fully reusable across blade changes. Available in M10-1.25 and M14-2 thread sizes to fit common European-spec angle grinders and stone-cutting polishers.

- Verify your angle grinder / polisher spindle thread matches the adapter (M10-1.25 or M14-2).
- Place the Quad blade onto the adapter, aligning the four mounting holes with the adapter pins.
- Secure the blade with the four supplied screws and two nylon lock nuts — do not overtighten.
- Thread the assembled blade-and-adapter onto the tool spindle hand-tight.
- Use the tool’s spindle-lock and an open-end wrench for final tightening per the tool manual.
- Confirm the blade rotates true; replace the adapter if any cracking, thread wear or screw damage is visible.
- After cutting, remove dust and slurry from the brass body and screw threads before storage.
- Reuse the adapter across blade replacements; replace screws and lock nuts as a set when worn.

What blade pattern does the Quad Adapter fit?
It is engineered specifically for flush-cutting blades with four mounting holes (the Alpha® Quad / Quad Segmented pattern).
Why brass instead of aluminum?
Solid brass is dramatically stronger and longer-lasting than aluminum, which means a safer mount under cutting load and many more blade changes before replacement.
Which thread size do I need?
M10-1.25 fits most European-spec angle grinders; M14-2 fits larger European grinders and many stone polishers. Confirm your tool’s spindle thread before ordering.
Is the adapter reusable?
Yes — the adapter is designed to be reused across multiple blade changes. Replace the screws and nylon lock nuts as a set when worn.
Can I mount a Quad blade directly to the grinder flange without this adapter?
No. The countersunk holes drilled into the core of a Quad / Quad Segmented blade require the BAH adapter for safe mounting.
Is hardware included?
Yes — the adapter ships complete with four mounting screws and two nylon lock nuts.
Do you offer a screw / lock-nut replacement kit?
Yes — order Alpha® BAH-4SS Brass Adapter Screw Set for direct replacements.
Are 5/8"-11 thread versions available?
Yes — the 5/8"-11 brass adapter is sold as Alpha® BAH-5/8 in a separate Shopify listing.
