Features

• Reduces the force drawn in by the left twist drill.
• Long cutting edge and gentle cutting edge angle reduce remaining fiber cuts (sprinkling).
• The unique 4-flute and angle design improves roundness and reduces thrust force.
• Can be machined with or without pre-holes.
• The double margin effect enables high-precision drilling.
• The stepped design reduces thrust and improves hole accuracy.
• A machining tolerance of ±0.010 mm can be achieved using guide bushes.
• Work Material: CFRP only.
• For drilling of CFRP and metal layered plates.
• For reaming of CFRP and metal layers.
