Description
Version:
Cutting chisel edge with high centring accuracy due to strong core and special point geometry.
Particularly high alignment accuracy due to 4 guide chamfers which stabilise the drill even at extreme depths!
Convex cutting edges with honed edges and special flute profile for short chips, even on long chipping materials.
Particularly high alignment accuracy due to 4 guide chamfers which stabilise the drill even at extreme depths!
Convex cutting edges with honed edges and special flute profile for short chips, even on long chipping materials.
Advantage:
High process reliability and surface quality of the hole.
Note:
Flute length LC = L2 + 1.5 × DC.
For process reliability when using the 12×D drill, an initial centre drilling with NC spotting drills No. 121068 – 121130 is necessary.
Form HB and HE are supplied at the same price as HA.
Form HB: order with No. 123302.
Form HE: order with No. 123301 + 129100HE.
NEW GENERATION AVAILABLE!
Recommended successor products are No. 123225 and 123235.
