Guhring 9041070120050 Replaceable-tip Drill 1/2 in Shank

Product Description

The GUHRING 9041070120050 is a replaceable-tip drill body designed for precision hole-making in metal fabrication and machining environments. Built on the 4107 series platform, this tool accepts HT 800 WP inserts and covers a diameter range of 0.472 to 0.492 inches, allowing a single body to accommodate multiple tip sizes. Maximum drilling depth reaches 1.563 inches (39.7 mm), and overall length is 106 mm. The through-coolant design channels fluid directly to the cutting zone, extending insert life and improving chip evacuation during deep-hole operations. Machinists and tool-room technicians working on CNC machining centers are the primary users of this body.

This drill body is suited for production drilling applications in steel and similar materials where repeatability and insert interchangeability are required. The 3xD HT 800 WP toolholder style positions it for moderate-depth holes in a range of workpiece materials. The 1/2-inch shank diameter fits standard ER and straight-bore toolholders common on vertical and horizontal machining centers. The through-coolant feature makes it appropriate for applications where flood coolant alone is insufficient for chip control or thermal management at the cutting edge.

Key Features

• Accepts HT 800 WP replaceable inserts for quick tip changes without removing the body from the spindle
• Through-coolant design delivers fluid directly to the cutting zone for improved chip evacuation and heat control
• Diameter range of 0.472 to 0.492 inches accommodates multiple insert tip sizes on a single body
• 3xD toolholder style supports maximum drill depth of 1.563 inches (39.7 mm)
• Steel body construction with a 1/2-inch shank diameter for broad toolholder compatibility
• Flute length of 59 mm (2.323 inches) supports efficient chip flow throughout the drilling cycle

Compatibility

Compatible with HT 800 WP series replaceable-tip inserts. Designed as an OEM-style drill body for use in standard 1/2-inch straight-bore or collet-style toolholding systems on CNC machining centers.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered down and locked out per facility lockout/tagout procedures. Ensure the shank bore and mating surfaces are clean and free of chips before seating the body. Verify coolant-through connections are properly sealed before resuming spindle operation. Follow the insert manufacturer torque guidance when securing HT 800 WP tips to the body.
