Coolant-Thru Drill

At 15× diameter, this drill enters territory typically reserved for gun drills or BTA deep-hole systems — but at a fraction of the setup complexity. Purpose-engineered for crankshaft oil passages, long tie bolts, and heat-exchanger tube sheets. Full-diameter internal coolant delivery is mandatory.
