For Optimum Performance:
Use wet with plenty of coolant at the diamond tool -material
interface. Coolant retaining rings and drill head / collet assemblies
(water swivels) are available. Call for quotation. Run tool at proper
R.P.M. Call us for recommendations for your specific application. If
drilling efficiency begins to decrease, run a soft aluminum oxide stick
across the cutting edge of the coring bit. This will enable new cutting
points to be exposed within the metal bond. Dressing sticks are available
in packs of 10. Catalogue number #50013
