Tungaloy 6706823 Replaceable-tip Drill 0.669-0.705 in 5xd

Product Description

The TUNGALOY 6706823 is a replaceable-tip drill body from the DrillMeister series, designed for precision holemaking in metal cutting applications. It accepts a range of DMP-series indexable drill tips, allowing the body to be reused while only the cutting tip is swapped at wear. The drill covers a diameter range of 0.669 to 0.705 inches and reaches a maximum depth of 3.346 inches, corresponding to a 5xD depth-to-diameter ratio. A 3/4-inch Weldon flat shank provides positive rotational drive and secure clamping in compatible toolholders. Through-coolant capability delivers cutting fluid directly to the tip for chip evacuation and heat control in deep-hole operations. Typical users are CNC machinists and toolroom professionals working on production drilling cycles.

This drill body is suited to production and job-shop environments running CNC machining centers or CNC lathes with driven tooling. The 5xD depth ratio makes it appropriate for moderately deep hole applications in steel, cast iron, and similar workpiece materials. The Weldon flat shank style is a common standard in milling and drilling toolholders, simplifying setup on existing equipment. The through-coolant design is particularly effective when drilling materials that generate significant heat or produce long chips that need to be flushed from the hole.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the tool path is cleared before mounting or removing the drill body. Secure the Weldon flat shank in a compatible toolholder to the torque specification required by the toolholder manufacturer. Verify through-coolant passages are clear and coolant pressure is adequate before beginning the drilling cycle.
