M.A. Ford CXDSS 0840AP Cyclone Xd 3X Double Margin Drill 8.40mm

SKU CH-HVGB-B4XQP

Solid double-margin drill creates accurate 8.40 mm holes in three-times-diameter depth

  • 40 mm diameter fits precise hole sizes
  • 3× diameter depth capability extends reach
  • Double margin design improves hole straightness
  • Solid carbide construction resists wear longer
  • Cyclone Xd geometry enhances chip evacuation

Application and design

The M.A. Ford CXDSS 0840AP Cyclone Xd drill produces 8.40 mm holes with a 3X diameter depth capacity. Its double margin geometry improves hole straightness and surface finish in demanding materials. The solid carbide construction provides rigidity for accurate results in production environments.

Who should choose this tool

Machinists drilling 8.40 mm holes to 3X depth in steel, cast iron or high-temperature alloys will benefit from the guided margins. Shops needing deeper holes, larger diameters or indexable insert tooling should evaluate alternative ranges. The Prop 65 notice also applies for regulated workplaces.

Critical specification

The 8.40 mm cutting diameter is the single value that determines fit for the intended hole size. Verify this matches the required nominal diameter before ordering. No other dimension in the data overrides this primary specification.

Questions about this item

What shank standard does the CXDSS 0840AP use and what drill-chuck size does that limit me to?

The CXDSS 0840AP has a straight 8.40 mm shank, so it fits any three-jaw chuck that opens to at least 8.40 mm.

What clearance does the 8.40 mm body and double-margin design need inside the workpiece or fixture?

The drill body is 8.40 mm in diameter with two full-width margins, so the hole or bushing must be at least 8.40 mm clear all the way through.

How do I mount the CXDSS 0840AP in a drill press and what step is most often missed?

Open the chuck fully, insert the 8.40 mm shank until it seats, then tighten each jaw evenly; the step most often missed is checking run-out with a dial indicator before cutting.
