Version :
Excellent chip evacuation due to the unequal helical pitch of the flutes, guide rings and additional flute lands for very high precision when drilling. Maximum process reliability due to exactly matching tools within the overall system. Drilling up to the maximum depth without a pilot drill. Significantly increased tool stability due to the substantially strengthened core. Increased metal removal rates and outstanding tool lives lead to an economical high-end drilling process.
Note :
Flute length LC = L2 + 1.5 × DC.
