Cyclone Xd 5X Double Margin Drill

The M.A. Ford CXDSR2344AP is a solid carbide drill built for high-performance production drilling. Its 5X diameter flute length and double margin design suit CNC operations that demand hole straightness and surface finish in a single pass. Machinists working with alloy steels, stainless steels and high-temperature alloys will find the geometry reduces drift and improves chip evacuation. The 15/64 inch diameter targets common aerospace and automotive fastener clearances.

Solid Carbide Build and Double Margin Stability

The solid carbide substrate resists wear and deflection better than cobalt or HSS alternatives, extending tool life in abrasive materials. Two lands per flute guide the drill continuously, keeping the hole on centre through cross-holes, angled entries and deep cavities. This geometry also dampens vibration, which protects both the workpiece and the machine spindle during long cycles. No coolant-through channels are present, so external flood or mist cooling must be planned.

Replaces Conventional HSS

Shops moving from general-purpose HSS or single-margin carbide drills gain tighter tolerances and fewer secondary reaming operations. The upgrade pays off when hole position and finish are critical, such as in fixture drilling or close-tolerance bolt patterns. It is not suited for hand-held use, non-rigid setups or materials that require through-coolant delivery for chip control. Buyers needing larger diameters or different flute lengths must select another tool from the range.

Questions about this item

What shank standard does the 15/64 drill use and what does it cap?

The drill has a straight shank sized at 15/64 inch, so it fits any chuck or collet that accepts that diameter and caps the maximum bit size at 15/64 inch.

What physical clearance does the 15/64 double-margin drill need to fit in a holder?

The tool requires a holder with a 15/64 inch bore and enough flute length clearance for a 5X solid carbide body.

How is the 15/64 Cyclone Xd drill installed and what step is often missed?

Insert the straight shank fully into the chuck or collet, tighten securely, and verify the double margins run true — many users skip the run-out check.
