Tapered cross bit
Used under any rock drilling condition and mainly used for hard or
very hard rock formation because of it's comprehensive
adaptability. Compared with taper chisel bits, taper cross bits
have a better drilling performance because of carbide tips on cross
bits doubled, which means carbides shape are cross type on drill
bits. Taper cross bit is mainly used for hard or very hard rock
formation. | Description | Diameter | Length | Weight | | Taper degree a=6 °,7°,11°,12° ; Socket inside d=19,22,25mm | mm | mm | kg | | 28 | 71 80 | 0.19 | | 29 | 71 80 | 0.2 | | 30 | 50 67 71 80 | 0.3 | | 32 | 50 67 71 80 | 0.3 | | 33 | 71 80 | 0.32 | | 34 | 67 71 80 | 0.34 | | 35 | 67 71 80 | 0.35 | | 36 | 71 80 | 0.36 | | 38 | 67 71 80 | 0.42 | | 40 | 71 80 | 0.43 | | 41 | 71 | 0.45 | | 42 | 69 80 | 0.46 | | 44 | 80 | 0.47 | | 45 | 80 | 0.5 |
