Cyclone Xd 5X Drill No 31

The M.A. Ford Cyclone Xd 5X Solid Double Margin Drill No 31 is a power-tool accessory built for precision drilling tasks. It suits machinists and maintenance crews who need consistent hole quality in demanding materials. The solid double-margin design supports accurate alignment during operation. This item is supplied new from the manufacturer.

California Proposition 65 warnings

The product carries California Proposition 65 notices for chemicals known to cause cancer and birth defects or other reproductive harm. These warnings inform safe-handling practices such as using ventilation and protective equipment. They do not alter the drill’s mechanical function or included components. Buyers should review the notices before use.

Installation and common issues

The drill fits standard tool holders matching its No 31 specification for direct mounting. Secure clamping prevents runout that can degrade hole finish or break the tool. Incorrect feed rates or misalignment are typical causes of premature wear. Proper coolant use helps maintain performance.

Questions about this item

How often will the No 31 drill need to be replaced during high-volume production?

Replacement timing depends on the material being drilled and the feed rates used; the solid double-margin design is intended to extend tool life in repetitive operations.

What is the first limitation encountered when running the CXDSR1200AP continuously?

The cutting edges will reach their wear limit before the shank or margins fail, so edge dulling is the primary constraint under sustained use.

How much heat does the Cyclone Xd 5X generate during all-day drilling cycles?

The double-margin geometry improves chip evacuation, which helps control temperature rise, but actual heat output varies with workpiece material and coolant strategy.
