3.70 mm Cyclone Xd drill purpose

The M.A. Ford CXDSS 0370AP is a 3X solid double margin drill built for precision hole-making in demanding materials. It targets machinists and maintenance crews who need consistent diameter control and extended tool life on CNC or manual pneumatic rigs.

Installation notes and common issues

The shank fits standard pneumatic holders so changeover is quick, but the 3X length demands rigid clamping and accurate spindle run-out to avoid vibration. Insufficient coolant flow or misaligned entry frequently causes margin wear or breakage before the flute reaches full depth.

Suitable users and mismatched needs

This drill suits shops drilling deep, accurate holes in steel or alloy where the 3.70 mm diameter matches the spec. Operations needing larger diameters, higher flute counts, or carbide grades not listed here should evaluate alternative tooling.

Questions about this item

How can I confirm the 3.70 mm drill is cutting correctly after installation?

The solid double margin design should produce a straight, round hole at the 3.70 mm diameter with minimal vibration; check the finished bore with a gauge to verify size and surface finish.

What comes in the package and is anything else needed to use the drill?

The box contains the CXDSS 0370AP Cyclone Xd 3X drill only; a compatible pneumatic tool holder and compressed air supply must be provided separately.

Which capacity of the Cyclone Xd 3X series should I choose for a 3.70 mm hole?

Select the 0370AP model — its 3.70 mm diameter matches the required hole size exactly.
