Guhring 9041070170050 Replaceable-tip Drill 0.669-0.689in

Product Description

The GUHRING 9041070170050 is a replaceable-tip drill body designed for precision hole-making in metal and industrial workpiece materials. Built on the Series 4107 platform with a 3xD HT 800 WP toolholder style, this drill body accepts HT 800 WP insert tips and delivers a usable drill diameter range of 0.669 to 0.689 inches. The through-coolant design channels cutting fluid directly to the cutting zone, extending insert life and improving chip evacuation in deep-hole applications. At 132 millimeters overall length with an 82-millimeter flute length, this tool fits standard 3/4-inch shank toolholders found on machining centers and drill presses across production environments. Installation and operation are handled by machinists and CNC tooling technicians.

This drill body is suited for production drilling applications where repeatable hole diameters and fast insert changes are required. The replaceable-tip design eliminates the need to replace the full drill assembly when the cutting edge wears, reducing tooling cost per hole. It is appropriate for use on CNC machining centers, horizontal boring mills, and similar machine tools running through-coolant capability. Maximum drill depth reaches 55.8 millimeters, placing it in the 40 to 60 millimeter depth range category for 3xD drilling operations.

Key Features

• Accepts HT 800 WP replaceable insert tips for fast cutting-edge changes without removing the drill body
• Through-coolant design delivers fluid directly to the cutting zone for improved chip clearance and insert life
• Drill diameter range of 0.669 to 0.689 inches supports slight diameter adjustment via insert selection
• 3/4-inch shank diameter fits widely available toolholders on CNC machining centers and drill presses
• Series 4107 steel body construction provides rigidity in moderate to high-feed drilling applications
• Maximum drill depth of 55.8 millimeters suits 3xD depth-to-diameter ratio requirements

Compatibility

Compatible with HT 800 WP series replaceable insert tips. Designed for use with 3xD HT 800 WP toolholder-style setups accepting a 3/4-inch shank. Refer to the GUHRING Series 4107 insert selection guide to confirm insert tip compatibility for specific diameter and material requirements.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Before mounting or changing insert tips, ensure the machine spindle is fully stopped and locked out per facility lockout/tagout procedures. Verify that the machine spindle and toolholder are configured for through-coolant delivery before engaging coolant flow. Follow the insert manufacturer torque and seating specifications when securing replaceable tips to the drill body.
