Hertel 4006109 Indexable Insert Drill 0.7087in 4xd

Product Description

The HERTEL 4006109 is a straight-shank indexable insert drill designed for production drilling in metal fabrication and machining applications. It accepts two indexable inserts and carries a drill diameter of 0.7087 inches (18.00 mm) with a maximum drill depth of 2.8346 inches (72.00 mm), representing a 4xD depth-to-diameter ratio. The steel body has a flute length of 2.9528 inches and a total body length of 5.7480 inches. Coolant-through capability supports chip evacuation and insert life during high-throughput drilling. This tool is installed and operated by machinists and CNC setup technicians working with indexable tooling systems.

This drill is suited for right-hand cutting operations in shop environments where repeatable hole quality and fast insert changeout are priorities. The straight cylindrical shank measures 0.9843 inches (25.00 mm) in diameter and 2.2047 inches in length, making it compatible with standard collet chucks and hydraulic toolholders used on CNC machining centers, lathes with live tooling, and dedicated drilling machines. A collar diameter of 1.2598 inches provides a positive stop reference for consistent setup. The compatible insert style is HPMT052804-GP.

Key Features

• 4xD depth-to-diameter ratio delivers a maximum drill depth of 2.8346 inches in a single pass
• Coolant-through design supports chip flushing and extends insert service life
• Accepts 2 indexable HPMT052804-GP inserts for quick replacement without regrinding
• Right-hand cutting direction for standard spindle rotation
• Straight cylindrical shank seats securely in collet or hydraulic chuck systems
• Steel body construction provides rigidity for consistent hole geometry

Compatibility

Compatible insert style is HPMT052804-GP. The 4006109 is designed for use in HID-compatible indexable drill systems. Confirm insert and toolholder compatibility before installation using the manufacturer tooling catalog.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the control is in an e-stop or lockout state before loading or unloading inserts. Verify shank seating depth and runout with a dial indicator prior to cutting. Engage coolant-through supply at the recommended system pressure for the machine tool before initiating a drilling cycle.
