CHEMITOOL Countersink 6p Set HSSE-G M35 TIALN

The CHEMITOOL countersinkers were developed under careful manufacturing processes, in order to provide the professional with an excellent relation of quality and performance in metal drilling. This drill is distinguished by its excellent quality/value ratio. The HSS CHEMITOOL countersinker is made entirely of high-speed steel of M35 (5% Cobalt) quality, prepared for drilling in metals with a hardness up to 1200N/mm2., according to DIN 335 standard.
