Solid Carbide Drill 3.70 mm

The M.A. Ford Twister Xd 3X is a solid carbide drill bit with a 3.70 mm cutting diameter. It is designed for precision drilling in a variety of materials using standard power tools. The tool is supplied new and ships directly from the manufacturer.

Suited for high-precision holes

This drill suits machinists and technicians who need accurate 3.70 mm holes in metal or composite workpieces. It is not intended for larger diameters, impact driving, or applications requiring coolant-through tooling. Buyers needing different sizes or shank styles should look at other listings.

Simple chuck installation

The bit fits directly into a standard drill chuck or collet that accepts the shank. No special holders or adapters are required. The main risk is breakage if the workpiece is not clamped rigidly or if feed and speed rates are excessive for the material.

Questions about this item

What size drill chuck do I need to hold the 3.70 mm shank?

Use a chuck that accepts at least 3.70 mm so the solid carbide shank seats fully without slipping.

Will the Twister Xd 3X work in a standard cordless drill I already own?

Yes, it fits any drill with a 3.70 mm or larger chuck; just match the speed to the material you are drilling.

How can I confirm the drill is cutting correctly after I start?

Look for steady, curled chips and a smooth hole wall — burning or squealing means the feed or speed needs adjustment.
