Cyclone Xd 8X Coolant Fed Drill

The Cyclone Xd 8X Coolant Fed Double Margin Drill is a precision cutting tool built for demanding metalworking applications. It targets machinists and maintenance teams who need reliable hole production in tough materials. The 4.70 mm diameter suits specific pilot-hole and through-hole requirements. This new item ships directly from the manufacturer.

Double Margin Design and Coolant Feed

The double margin geometry improves hole straightness and surface finish by guiding the drill at two contact points. Internal coolant channels deliver fluid directly to the cutting zone, which extends tool life and aids chip evacuation. These features reduce the need for peck drilling cycles in deep holes. The shank fits standard holders for quick changeover.

Upgrading From Standard Twist Drills

This drill replaces conventional twist drills when hole accuracy and tool longevity are critical. The jump is worth it for high-volume runs or difficult alloys where coolant starvation causes premature wear. It is not suited for hand-held drilling or machines without through-spindle coolant capability. Buyers needing larger diameters or different lengths must select other variants.

Questions about this item

How does the coolant-fed design affect the 4.70 mm drill's performance?

The internal coolant channels deliver fluid directly to the cutting edges, improving chip evacuation and heat control during deep-hole drilling.

What holder and machine setup does the 4.70 mm Cyclone Xd drill require?

A precision collet or hydraulic chuck with through-coolant capability is needed, plus a rigid machine spindle to maintain run-out within tight limits.

What is the critical step when installing this 4.70 mm drill for the first time?

Verify the coolant passages in the holder and spindle are fully open and aligned before starting the machine to avoid dry cutting.
