DART 16mm Four Wing Auger Bit D4AB16

DART Auger Bits (Precision Ground)

DART auger bits deliver fast, clean drilling across all types of timber—softwood, hardwood, chipboard, and veneered panels—thanks to their precision-ground cutting edges. With a self-centering threaded tip and dual cutting spurs (main spur + pre-cutting spur), they start accurately, pull smoothly into the material, and leave a clean hole with minimal breakout. The optimised flute design ensures rapid chip removal, reducing friction and preventing jamming during deep drilling.

These auger bits are available in a wide range of diameters (6 mm to 38 mm) and multiple working lengths, including short (100/57 mm), standard (230/170 mm), and extra-long (460/370 mm), offering a solution for every application from quick pilot runs to deep structural drilling. Hex and SDS shank options provide compatibility with the most common drilling machines.
