Product Identity

The M.A. Ford HPDCR 0990A Twister HPD coolant drill is a 5X diameter tool with a 9.90 mm cutting diameter. It is engineered for high-performance drilling operations where through-coolant delivery is required.

Suitability

This drill suits machinists who need a 9.90 mm hole produced with internal coolant supply at five times diameter depth. It does not suit buyers who need a different diameter or a non-coolant design.

Critical Specification

The decisive specification is the 9.90 mm cutting diameter combined with the 5X length ratio and through-coolant capability; verify that both the size and the depth requirement match your application before purchase.

Questions about this item

What comes in the box with the HPDCR 0990A Twister HPD coolant drill 5X?

When would I choose the 9.90 mm 5X version over other sizes?

Choose this 9.90 mm diameter drill when the hole size matches that specification and the 5X length provides the reach your application requires.

How does the 5X length affect drilling depth in practice?

The 5X length allows a deeper hole in a single pass while the internal coolant channel helps clear chips and control heat during the cut.
