Hertel 4006104 Indexable Insert Drill 7/8 in 4xd

Product Description

The HERTEL 4006104 is a straight-shank indexable insert drill designed for high-productivity hole-making in metal cutting applications. The body accepts two HPMT063206-GP style inserts and cuts right-hand with a 7/8 inch (0.8750 inch decimal) drill diameter and a maximum drill diameter of 0.9010 inches. The 4xD depth-to-diameter ratio supports a maximum drill depth of 3.5 inches, making it well suited for deep-hole drilling cycles in production environments. Built from steel with coolant-through capability via a 1/4 inch shank-end coolant hole thread, this drill is engineered for use on CNC machining centers where through-spindle or through-tool coolant is available.

This indexable insert drill is used in production machining operations on CNC vertical and horizontal machining centers. The straight cylindrical shank at 1.0000 inch diameter fits standard ER or hydraulic toolholders common in production shops. The drill is appropriate for ferrous and non-ferrous material boring where consistent hole geometry and insert indexability are priorities. It is suited for aerospace, automotive, die and mold, and general job shop environments where repeatable hole quality and fast cycle times are required.

Key Features

• 4xD depth-to-diameter ratio allows up to 3.5 inches of drilling depth in a single pass
• Accepts 2 indexable inserts for fast edge changes without removing the body from the holder
• Compatible insert: HPMT063306-GP
• Coolant-through design with 1/4 inch shank-end coolant hole thread for chip evacuation and heat management
• Straight cylindrical shank at 1.0000 inch diameter for broad toolholder compatibility
• Right-hand cutting direction; flute length of 3.618 inches supports chip clearance at full depth

Compatibility

Compatible insert style: HPMT063306-GP. Designed for use with HID-style indexable drill systems. Straight cylindrical shank is compatible with standard 1 inch bore toolholders on CNC machining centers.

Installation Notes

Installation and setup should be performed by a qualified machinist or tooling technician. Confirm the toolholder bore matches the 1.0000 inch shank diameter and that the holder provides adequate clamping torque per the toolholder manufacturer specification. Verify coolant-through pressure compatibility before engaging through-tool coolant. Inspect insert seating and secure all insert screws with the correct Torx or hex key before initiating any cutting cycle.
