10.90 mm double-margin drill bit

The M.A. Ford CXDSR 1090AP Cyclone Xd is a solid carbide drill with a 10.90 mm cutting diameter. It features a 5× diameter flute length and a double-margin design for improved hole straightness. The tool targets machinists producing accurate holes in steel, cast iron and high-temperature alloys.

Heat and power in normal use

The double-margin geometry distributes cutting forces across two lands, reducing localised heat buildup during extended drilling cycles. This lowers the risk of thermal expansion that can widen the hole beyond tolerance. Stable torque load also means the machine spindle draws consistent power without sudden spikes.

Shank fit and workshop routine

The cylindrical shank fits standard drill chucks and collet holders without special adapters. Solid carbide construction resists chipping when the bit enters hard materials at speed. California Proposition 65 warnings apply, so operators should use appropriate personal protective equipment and ventilation during use.

Questions about this item

How do I install the 10.90 mm Cyclone Xd 5X drill in a standard drill chuck, and what step is often missed?

Open the chuck fully, insert the shank until it seats, then tighten securely; the step often missed is verifying the drill runs true before starting the cut.

What maintenance or replacement will the 10.90 mm Cyclone Xd 5X drill need after extended use?

The cutting edges will dull and require professional resharpening or replacement of the drill when the margins no longer produce clean holes.

What limit appears first on the 10.90 mm Cyclone Xd 5X drill during sustained drilling?

Heat buildup at the cutting edges is the first limit, causing accelerated wear and reduced hole quality if feed and speed are not controlled.
