Description
Version:
Single-edged straight flute deep-hole drill for drilling depths of up to 1000 mm as standard and up to 6000 mm on request. Universally designed circumferential shape of the drilling head enables reliable working in a wide range of materials.
Note:
For the reliable use of deep hole drills, a pilot hole of at least 4×D with pilot drill No. 122736 or No. 231605 for larger diameters, or with pilot drill No. 122606 for aluminium, is required. For deep holes > 50×D, the tool must be supported with a rest at intervals of 50×D. The specified L/D ratio gives the minimum achievable depth of hole with the respective deep-hole drill. Flute length LC = L2 + 1.5 × DC. A coolant pressure of > 40 bar is recommended.
