Drill Bit 4.40 mm
The M.A. Ford Twister Brad And Spur Drill 20717320 is a 4.40 mm cutting tool designed for precision drilling in wood and similar materials. It suits woodworkers and tradespeople who need clean entry holes with minimal splintering. The brad point centres the bit accurately while the spur cutting edges shear fibres cleanly. This accessory fits standard drill chucks for handheld or bench-mounted use.
Replaces Worn Brad Bits
Switch to this bit when an existing brad point drill shows dulled spurs, chipped lips or wandering starts that ruin hole quality. The upgrade is worth it if tear-out on the workpiece face has become unacceptable or if centre-point wear forces excessive feed pressure. A fresh Twister restores crisp perimeter scoring and accurate hole placement without reaming. It also eliminates the need for secondary cleanup passes.
Sustained Cutting Behaviour
Under continuous drilling the high-speed steel body resists heat build-up better than carbon-steel alternatives, keeping the cutting edges sharp for longer runs. The open flute geometry clears chips efficiently so the bit does not bind or overheat in deep holes. Consistent feed rates stay manageable because the spur geometry reduces the torque spike typical of twist drills. The bit maintains diameter accuracy across multiple holes in a single session.
