3.40 mm Solid Double Margin Drill

The M.A. Ford Cyclone Xd 3X drill is a 3.40 mm solid carbide cutting tool designed for high-performance drilling applications. Its double margin design improves hole straightness and surface finish while providing enhanced stability during operation. This accessory targets professional machinists and maintenance technicians who require precision holes in difficult-to-machine materials.

Who this suits and who should look elsewhere

This drill suits users needing a rigid 3X diameter solid carbide tool for accurate holemaking in tough alloys. It is not for buyers who require a longer flute length for deep-hole drilling beyond the 3X ratio. It is also not for operators needing a coolant-through design for high-pressure chip evacuation in blind holes.

3.40 mm cutting diameter

The 3.40 mm cutting diameter is the primary specification that determines compatibility with your hole size requirement. This exact dimension must match the pilot hole or final hole specification on your engineering drawing. Verify the tolerance requirements of your application against this fixed diameter before purchase.

Questions about this item

Will the 3.40 mm shank fit the collet on my older CNC spindle?

The drill has a 3.40 mm diameter shank. Measure your collet bore or check its spec sheet; a 3.40 mm round shank requires a matching 3.40 mm collet or a compatible reducing sleeve.

How can I confirm the CXDSS 0340AP is cutting correctly after installation?

Run a test hole in the target material. A properly functioning drill produces a straight, round hole at 3.40 mm diameter with minimal burr and consistent chip evacuation from the double-margin flutes.

Does the box include any collets, sleeves or coolant adapters, or just the drill?

Only the Cyclone Xd 3X solid double-margin drill itself is supplied. Collets, reducing sleeves, coolant fittings and tool holders are sold separately.
