Beta Tools Copper-Berillium (Cu-Be) Spark-Proof Tools are specifically designed for safe operations in environments subject to potential risk of explosion, in the presence of flammable liquids and gases, or for any applications that require using perfectly antimagnetic, corrosion-resistant tools.All tools are certified by the Federal Institute for Materials Research and Testing (BAM) under European Directive 99/92/EC.Warning! Risk of explosion in ACETYLENE environment. The mechanical characteristics of spark-proof tools differ from those of normal steel tools. They should be used with extreme caution, avoiding overloads..tg {border-collapse:collapse;border-spacing:0;}.tg td{font-family:Arial, sans-serif;font-size:14px;padding:10px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;border-color:black;}.tg th{font-family:Arial, sans-serif;font-size:14px;font-weight:normal;padding:10px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;border-color:black;}.tg .tg-s268{text-align:left} Product Code Part Number Size L Ø S Weight \" mm mm mm g 000780908 78BA-AS 11/16 11/16 145 32 12 210 000780909 78BA-AS 3/4 3/4 145 32 12 200 000780935 78BA-AS 7/8 7/8 155 38 13 245 000780936 78BA-AS 15/16 15/16 165 42 14 250 000780938 78BA-AS 1 1 175 46 16 350 000780940 78BA-AS 1.1/8 1.1/8 180 50 16 455 000780910 78BA-AS 1.1/4 1.1/4 177 54 23.5 570 000780912 78BA-AS 1.7/16 1.7/16 208 60 26.5 780 000780914 78BA-AS 1.5/8 1.5/8 225 67 26 950 000780916 78BA-AS 1.13/16 1.13/16 243 74 28 1235 000780918 78BA-AS 2 2 254 78 28.5 1500 000780920 78BA-AS 2.3/16 2.3/16 264 84 30 1685 000780922 78BA-AS 2.3/8 2.3/8 275 91.5 30 1960 000780924 78BA-AS 2.9/16 2.9/16 286 99.5 31.5 2400 000780926 78BA-AS 2.15/16 2.15/16 311 112.5 33.5 3110 000780928 78BA-AS 3.1/8 3.1/8 325 118 35.5 3500 000780930 78BA-AS 3.1/2 3.1/2 355 130 39 4600
