The Milwaukee SDS MAX drill bits are available in a range of different sizes. They feature a wear mark on both sides of the cutter so show remaining lifetime of the drill bit, they have patented reinforced flute geometry for lower vibrations, the stronger flute results in less breakages and gives a better transfer of the hammer energy to the tip. The drill bit has deep flute shoulders which gives a high volume of dust removal. These drill bits have a 130 degree point angle for accurate drilling. Here are all the working lengths for the drill bits available: 16x340mm = 200mm working length 16x540mm = 400mm working length 18x540mm = 400mm working length 20x520mm = 400mm working length 22x520mm = 400mm working length 24x540mm = 400mm working length 25x520mm = 400mm working length 28x570mm = 450mm working length 30x570mm = 450mm working length 32x570mm = 450mm working length 35x570mm = 450mm working length Large carbide tip with patented rabar chamfers. More carbide on all the diameters. 130 degree point angle for accurate drilling. Shorter spiral windings for faster removal of the dust. Patented reinforced flute geometry. Wear mark on both sides of the cutter.
