Tungaloy 6723443 Replaceable-tip Drill 0.866-0.902in 3xd

Product Description

The TUNGALOY 6723443 is a replaceable-tip drill body from the DrillMeister series, engineered for precision holemaking in metal cutting applications. The drill accepts interchangeable DMP-series tips, allowing tip changes without removing the body from the spindle. It covers a diameter range of 0.866 to 0.902 inches and delivers a maximum drilling depth of 2.598 inches at a 3xD depth-to-diameter ratio. A 1-inch Weldon Flat shank provides positive rotational drive and secure clamping in compatible toolholders. Through-coolant capability directs cutting fluid directly to the tip for effective chip evacuation and thermal management at the cutting zone. This drill body is installed by machinists and CNC operators in production and job-shop environments.

The 6723443 is suited for drilling and holemaking operations on machining centers, CNC lathes with live tooling, and drill presses equipped with compatible Weldon Flat holders. The replaceable-tip design is well-suited to high-volume production runs where rapid tip changes reduce downtime. The 3xD depth ratio covers a broad range of through-hole and blind-hole applications in ferrous and non-ferrous workpieces. Compatible insert styles are the DMP210, DMP211, DMP212, DMP213, DMP214, DMP215, DMP216, DMP217, DMP218, and DMP219.

Key Features

• Replaceable DMP-series tip system eliminates full tool replacement between jobs
• Through-coolant design improves chip flushing and extends tip life in deep-hole applications
• Weldon Flat shank provides positive drive and resists slippage under high torque
• 3xD depth-to-diameter ratio suits the majority of standard drilling operations
• DrillMeister series body compatible with ten DMP insert styles for material-specific optimization

Compatibility

Compatible insert styles: DMP210, DMP211, DMP212, DMP213, DMP214, DMP215, DMP216, DMP217, DMP218, and DMP219. Requires a toolholder with a 1-inch Weldon Flat bore and through-coolant capability to take full advantage of all features.

Installation Notes

Installation and tip changes should be performed by qualified machinists following the machine tool manufacturer lockout/tagout procedures before any tooling work. Confirm the toolholder bore matches the 1-inch Weldon Flat shank before mounting. Set coolant pressure and flow to the drill manufacturer recommendations for through-coolant tooling. Inspect the tip seating surface and locking mechanism for wear or debris before each tip installation to maintain runout tolerances.
