4.40 mm Solid Double Margin Drill
The M.A. Ford CXDSR 0440AP Cyclone Xd 5X is a solid carbide drill designed for high-performance drilling applications. Its double margin geometry improves hole straightness and surface finish while providing enhanced stability during deep-hole operations. The 5X diameter-to-length ratio supports efficient chip evacuation in a single pass. This accessory targets professional machinists and maintenance technicians requiring precise, repeatable results in production environments.
For CNC and high-accuracy manual drilling
Suited for users drilling steel, stainless steel, and high-temperature alloys where hole quality and tool life are critical. The double margin design reduces walk and vibration, making it effective for cross holes, angled entries, and interrupted cuts. Buyers needing coolant-through capability or diameters outside 4.40 mm should look at alternative tooling. Operations restricted to shallow depths or softer materials may not justify the premium geometry.
4.40 mm cutting diameter
The 4.40 mm diameter is the primary specification that determines compatibility with the required hole size and pre-drill tolerances. It fixes the tool's fit for specific pilot holes, tap drill charts, and reaming allowances. Verify the exact diameter matches the engineering drawing before purchase, as no other size variant is included. The solid carbide construction and double margin profile support the diameter's performance but do not alter its nominal value.

Questions about this item
How do I install the 4.40 mm Cyclone Xd drill in my drill press, and what step is often missed?
Secure the 4.40 mm shank fully in the chuck or collet, then verify run-out before starting; the step most often missed is checking concentricity after tightening.
What maintenance or replacement will the 4.40 mm double-margin drill need later?
The solid carbide drill will eventually need resharpening or replacement once the cutting edges wear; no other consumable parts are involved.
What limit appears first on the 4.40 mm Cyclone Xd drill during sustained high-speed drilling?
Heat buildup at the cutting edges is the first limiting factor; excessive temperature accelerates edge wear and can reduce hole quality.
