8.50 mm Brad and Spur Drill

The M.A. Ford Twister Brad and Spur Drill, part number 20733460, is a precision cutting tool for clean holes in wood and similar materials. Its brad-point tip centres the bit accurately while the outer spurs shear fibres for a smooth entry and exit. The 8.50 mm diameter suits joinery, cabinetry and general woodworking tasks where hole quality matters.

Shank fit and workpiece check

Confirm that your drill chuck accepts the shank diameter of this bit before ordering. Ensure the workpiece is clamped securely and that the material thickness allows the full flute length to clear chips without binding. Verify the 8.50 mm hole size matches your fastener or dowel specification to avoid rework.

Build quality and daily use

The Twister designation indicates a flute geometry designed for efficient chip evacuation and reduced heat buildup during repeated drilling. High-speed steel construction resists wear in abrasive woods and composites. The brad and spur profile minimises wander on start-up, letting you drill accurate holes quickly without a centre punch.

Questions about this item

What comes in the box with the M.A. Ford Twister Brad and Spur Drill 20733460 and what else do I need?

The package contains the 8.50 mm Twister Brad and Spur Drill itself; no additional accessories or pilot bits are included, so ensure your drill chuck accepts this shank size before use.

How do I know the 8.50 mm version is the right one for my job?

Choose this 8.50 mm drill when you need a clean, flat-bottomed hole of exactly that diameter in wood or composite material; the brad point centres the cut and the spur scores the fibres for a splinter-free edge.

What does the California Proposition 65 warning on the 20733460 mean for daily workshop use?

The warning indicates the drill contains a listed chemical; follow normal shop hygiene — wear gloves if handling for long periods, avoid inhaling dust, and wash hands after use to minimise exposure.
