Twister Xd 5X Coolant Fed Drill

The M.A. Ford Twister Xd 5X is a coolant-fed drill bit with a 3.70 mm diameter. It is built for high-performance drilling in demanding industrial applications. The internal coolant channels deliver fluid directly to the cutting zone. This design helps manage heat and improve chip evacuation during deep-hole operations.

For CNC and precision machining setups

This drill suits workshops running CNC machines with through-spindle coolant capability. It is not for handheld drilling or machines without internal coolant supply. Buyers needing a standard twist drill without coolant holes should look at a different tool style. The 5X designation indicates a specific flute geometry for targeted materials.

3.70 mm cutting diameter

The single specification that decides fit is the 3.70 mm cutting diameter. This exact size must match the hole requirement in your engineering drawing or bill of materials. Verify the dimension before ordering to ensure the correct hole size is produced. No other diameter variant is covered by this listing.

Questions about this item

What spindle and holder does the 3.70 mm Twister XD drill require?

The 3.70 mm drill fits a matching 3.70 mm collet or hydraulic chuck; the shank diameter equals the cutting diameter.

What is the coolant-pressure step that installers often skip?

Start coolant flow before the drill contacts the workpiece so the through-tool channels prime fully.

When should the 2XDCR1457A drill be replaced?

Replace the drill when corner wear or flank wear reduces hole accuracy or when the tool can no longer hold the 3.70 mm diameter within tolerance.
