Hertel 4006103 Indexable Insert Drill 13/16 in 4xd

Product Description

The HERTEL 4006103 is a straight-shank indexable insert drill designed for high-productivity hole-making in metal cutting applications. It accepts two HPMT063306-GP inserts and delivers a drill diameter of 13/16 inches (0.8125 inches decimal) with a maximum drill diameter of 0.8370 inches. The 4xD depth-to-diameter ratio allows a maximum drill depth of 3-1/4 inches in a single pass. Built from steel with coolant-through capability, this tool is intended for use by machinists and tooling professionals on CNC machining centers and drill presses where rigid, repeatable hole geometry is required.

This drill is suited for production and job-shop environments where indexable tooling reduces downtime versus regrindable drills. The straight cylindrical shank with a 1-inch diameter fits standard ER and hydraulic toolholders common in vertical and horizontal machining centers. Right-hand cutting direction makes it compatible with standard spindle rotation. The coolant-through design, with a 1/4-inch shank-end coolant hole thread, supports high-pressure coolant delivery to extend insert life and aid chip evacuation in deep-hole applications.

Key Features

• Indexable insert design accepts 2 HPMT063306-GP inserts for quick changeover without regrinding
• Coolant-through construction with 1/4-inch threaded shank-end port for high-pressure coolant delivery
• 4xD drill depth ratio enables 3-1/4-inch maximum depth in a single pass
• Straight cylindrical 1-inch shank fits standard machining center toolholders
• Right-hand cutting direction for use with standard spindle rotation
• Steel body construction for rigidity and durability in production environments

Compatibility

Designed for use with HPMT063306-GP indexable inserts. The 1-inch straight cylindrical shank is compatible with standard ER collet chucks, hydraulic chucks, and shrink-fit holders sized for 1-inch shanks.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the drill body or inserts. Verify insert seating and fastener torque per the insert manufacturer's tooling guidelines before initiating a cut. Confirm coolant line pressure and flow rate are appropriate for the application before engaging coolant-through operation.
