Sandvik Eccentric Sleeve For U Drill

*The flange flange holes are for reference only. Since there is a margin for expanding the drilled holes, please measure and adjust the diameter of the drilled holes. *Since the drill body rubs, it is not possible to finish the machined hole diameter smaller than the nominal diameter of the drill. Make negative adjustments only if oversized holes are formed. *By attaching the sleeve, the protrusion will be 5mm longer. You also need to change the drill arbor. *The machined surface roughness may decrease and it may be difficult to adjust the machined diameter.

When using the CoroDrill 880 and CoroDrill 881 cylindrical flattening shanks, you can adjust the machining hole diameter by setting a sleeve between the drill shank and the holder. (Guideline for adjusting the hole diameter adjustment range -0.1mm to +0.3mm)
