11.70 mm coolant-fed drill for deep holes

The Cyclone Xd 5X drill from M.A. Ford is built for 11.70 mm diameter holes with a 5X diameter depth capability. Coolant-fed flutes evacuate chips from deep cavities in steel and alloy workpieces. Double margins improve hole straightness and surface finish in production runs.

Heat management and power draw in use

Internal coolant channels deliver cutting fluid directly to the tip, reducing thermal buildup at the cutting edges during extended cycles. Efficient chip evacuation lowers spindle load and prevents packing that can stall the cut. The design targets consistent performance without excessive force on the machine spindle.

Double margins and coolant feed change the process

Two margin lands guide the drill for tighter diameter control and reduced wander in cross holes or angled entries. Through-tool coolant eliminates the need for external flood systems in many setups. The geometry suits high-volume drilling where hole quality and tool life are critical.

Questions about this item

How is the 11.70 mm Cyclone Xd drill installed in a coolant-fed holder, and what step is often missed?

Mount the drill in a compatible coolant-through holder, align the shank flats with the locking screws, then connect the coolant supply before tightening; skipping the coolant connection causes premature wear.

What maintenance or replacement will the 1170AP double-margin drill need during its service life?

Inspect the cutting edges and margin lands regularly; resharpen or replace the drill once the margins show rounding or the coolant holes become obstructed by swarf.

What limit appears first when the 11.70 mm drill runs continuously under high feed rates?

The double-margin design improves stability, but sustained high feeds generate heat at the margins first, leading to margin wear before the cutting lips dull significantly.
