Manufactured from premium HSS steel with 5% Cobalt (Co) content, these drill bits offer significantly enhanced heat resistance and extended service life compared to standard HSS bits.

The 135° split point grinding ensures perfect centring at the start of each hole, whilst reducing the drilling pressure required for clean, accurate results. An industrial quality ground flute design facilitates high accuracy drilling and efficient chip removal, preventing clogging and maintaining optimal performance throughout use.
