V-point drill bits or through-hole bits are widely used to drill through solid wood or wood composites for the insertion of dowels. factory offers high-precision and long-lasting V-point dowel bits for creating clean holes with high efficiency. Our advanced flute design allows for the best accuracy, smooth chip removal, and burr-free holes. Both TCT and solid carbide through boring bits are available. The carbide-tipped V-point bits range from 5mm to 12mm in cutting diameter, while our solid carbide bits size from 3mm to 8mm in cutting diameter. Our V-point dowel drill bits feature standard overall lengths of 57mm and 70mm, coming with both left-hand and right-hand rotations. You could make your choice based on the diameter needed, the overall length, and the rotation type of the boring bits
