HIGH SPEED STEEL - GROUND FLUTE CONSTRUCTION:
Ground Flute jobber drillbits are made from High Speed Steel of superior quality and manufactured to Industry Standard DIN 338. High Speed Steel, (HSS), drill bits are suitable for drilling into most types of material including metal, wood and plastics. Ground flute have a longer life span than the equivalant roll forged.
HEAVY DUTY SERVICE:
They are suitable for drilling into metal because the HSS is designed to stand up to the high temperatures created when drilling through these tough materials. They are a superior drill bit to the older high-carbon steel variety as they cut faster and have a greater hardness. Our Ground Flute jobber drills are built to last and get the job done! They are suitable for drilling metals, hardwoods and most other materials at greater cutting speeds than carbon steel bits.
