What it is
The DeWalt DT90239-QZ Extreme Tri Flute bit is a self-feed wood drill bit with a diameter of 13 mm, an overall length of 152 mm and a working length of 100 mm. The self-feed geometry allows the hole to be started without pre-punching, while the Tri Flute profile aids chip removal for clean, continuous drilling even in considerable thicknesses.
A self-feed wood bit is a three-cutter bit with a centring screw that pulls itself into the wood, for large-diameter through holes.
What it is for
Used for drilling wood and panels.
How to use it
Fit the bit securely in the drill, place the screw point on the mark and start at low speed, letting the bit feed itself without pushing. Grip the machine firmly, preferably with the side handle, as it can twist suddenly if the bit jams. To avoid breakout, slow down when the screw point emerges and finish the hole from the opposite side.
