Hertel 4006135 Indexable Insert Drill 0.7087 in 3xd

Product Description

The HERTEL 4006135 is a 3xD indexable insert drill designed for metal-cutting applications in production and job-shop environments. The tool bores to a maximum depth of 2.126 inches at a nominal drill diameter of 0.7087 inches (18.00 mm). It accepts two HPMT052804-GP inserts and is built from steel construction with a straight-cylindrical shank. Coolant-through capability supports chip evacuation and thermal management at higher feed rates. The 0.9843-inch shank diameter seats securely in standard toolholders, and the right-hand cutting direction suits conventional CNC and manual machining setups.

This drill is suited for through-hole and blind-hole drilling operations in ferrous and non-ferrous materials where repeatable hole quality and insert replaceability are priorities. The HID drill style compatibility makes it a direct fit for operations already running HERTEL HID-platform tooling. Machinists, tool-and-die professionals, and CNC operators working in general metalworking, mold making, and production machining are the primary users. The 3xD depth-to-diameter ratio covers the majority of common drilling depths without requiring a boring extension or step drill.

Key Features

• Drill diameter of 0.7087 inches (18.00 mm) with a maximum allowable diameter of 0.7300 inches
• 3xD depth ratio with a maximum drill depth of 2.126 inches (54.00 mm)
• Takes two HPMT052804-GP indexable inserts for fast edge changes without full tool replacement
• Coolant-through design for improved chip flushing and insert life at elevated cutting speeds
• Straight-cylindrical shank, 0.9843 inches (25.00 mm) diameter, for broad toolholder compatibility
• Right-hand cutting direction; compatible with HID drill style holders

Compatibility

Designed for use with HID-style drill bodies and accepts HPMT052804-GP indexable inserts. Verify insert seat condition and holder bore tolerance before mounting.

Installation Notes

Installation and insert changes should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before seating or removing inserts. Confirm shank-to-holder fit and set screw or collet clamping torque per the machine builder's toolholder specifications. Activate coolant-through supply before engaging the cut to prevent thermal shock to the insert edge.
