Guhring 9041120222200 Carbide Replaceable Tip Drill 7/8

Product Description

The GUHRING 9041120222200 is a Series 4112 carbide replaceable tip drill designed for high-performance hole-making in steel and stainless steel applications. The drill tip is manufactured from solid carbide and coated with a Nano-FIREX finish applied via a PVD coating process, which improves wear resistance and extends tool life in demanding cut conditions. The 2-facet insert geometry and 140-degree included angle support clean entry and reliable chip formation. At 0.036 pounds, this is a lightweight tooling component suited for precision drilling operations where tip replacements help reduce overall tooling cost.

This replaceable tip drill is intended for use in CNC machining centers and drilling applications targeting steel (ISO material code P) as the primary workpiece material, with secondary suitability for stainless steel (ISO material code K and M). The 7/8 inch diameter and Series 4112 insert seat size 220 make it a fit for medium-bore precision drilling operations in production machining environments. It is typically installed and operated by machinists and tooling specialists working in metal fabrication, aerospace, and general manufacturing.

Key Features

• Solid carbide tip construction for consistent performance in ferrous workpiece materials
• Nano-FIREX PVD coating improves surface hardness and thermal resistance during cutting
• 140-degree point angle with 2-facet geometry supports accurate drill entry and chip control
• Replaceable tip design reduces tooling waste and lowers cost per hole over the drill body life
• Compatible with ISO P and K/M workpiece material classifications including steel and stainless steel
• Insert seat size 220 ensures precise tip seating and repeatable positioning on the drill body

Compatibility

Designed as an OEM-style replaceable tip insert for Series 4112 drill bodies using insert seat size 220. Consult the GUHRING Series 4112 body selection guide to confirm shank and body compatibility before ordering.

Installation Notes

Replaceable tip drills should be installed and changed by qualified machinists following the tool manufacturer's torque and seating procedures for the specific drill body. Ensure the machine spindle is fully stopped and the tool holder is secured before tip removal or installation. Inspect the insert seat for debris or damage before seating a new tip, as contamination in the seat can affect runout and tip retention. Follow applicable shop safety protocols and machine guarding requirements during all tooling changes.
