M.A. Ford Twister Brad and Spur Drill 4.00mm pneumatic accessory 20715750

4.00 mm Brad and Spur Drill

The M.A. Ford Twister Brad and Spur Drill is a 4.00 mm pneumatic accessory designed for precision drilling in wood and similar materials. It suits woodworkers and maintenance technicians who need clean entry holes and accurate centre points. The brad point reduces wandering at the start of the cut, while the spur edges shear fibres for a smooth bore. This new tool carries manufacturer part number 20715750.

Sustained drilling behaviour

Under continuous pneumatic drive the bit maintains a steady cutting action without the speed drop-off common in high-speed steel twist drills. The spur geometry clears chips efficiently, preventing the binding that causes heat buildup during long holes. Operators can run repeated cycles without frequent withdrawal to clear swarf. Consistent feed pressure yields repeatable hole quality across a production run.

Heat, noise and air consumption

The drill body runs cool because the cutting edges shear rather than scrape, limiting friction-generated heat during normal use. Noise levels are typical for pneumatic tooling and depend mainly on the air motor and exhaust silencing fitted to the driver. Air consumption matches the flow required by the host pneumatic drill; no additional supply capacity is needed beyond what the driver already demands.
