Cyclone Xd 5X Double Margin Drill

The Cyclone Xd 5X is a solid carbide drill featuring a double margin design for improved hole straightness and surface finish. It is intended for machinists and maintenance technicians who need accurate drilling in a variety of materials. The 8.70 mm diameter suits specific hole-making requirements in professional workshops.

Installation and common issues

Secure the drill in a precision collet or hydraulic holder to maintain concentricity and prevent runout. Use appropriate coolant pressure and peck cycles for the material being drilled. Vibration or premature wear usually indicates incorrect speed, feed or insufficient workpiece clamping rigidity.

Capacity and headroom

The 8.70 mm cutting diameter determines the hole size this tool produces in a single pass. It comfortably handles production drilling depths up to five times diameter in steels and cast irons. The tool reaches its limit when hole diameters larger than 8.70 mm are required or when machine power cannot sustain the necessary cutting forces.

Questions about this item

How can I verify the 8.70 mm Cyclone Xd drill is cutting correctly after installing it?

The drill should produce a straight, accurately sized 8.70 mm hole with consistent chip evacuation and no chatter when run at the recommended speed and feed for the workpiece material.

What comes with the CXDSR 0870AP drill and what must I supply separately?

The package contains the solid carbide 8.70 mm double-margin drill only; you must provide a compatible tool holder, coolant or lubrication, and a machine spindle capable of the required RPM.

Which diameter version of the Cyclone Xd 5X series should I select for an 8.70 mm hole?

Choose the CXDSR 0870AP model, which is the 8.70 mm variant; other diameters in the range are identified by their own three-digit millimetre codes.
