Guhring 9041120234200 Carbide Replaceable Tip Drill 59/64

Product Description

The GUHRING 9041120234200 is a carbide replaceable tip drill designed for high-productivity drilling in steel and stainless steel applications. Part of the Series 4112 platform, it accepts a solid carbide replaceable tip with a 2-facet insert geometry and a 140-degree included angle, which supports aggressive entry and self-centering on a variety of workpiece materials. The HT800 substrate is finished with a Nano-FIREX PVD coating, a multilayer nano-composite film engineered to reduce heat buildup and extend edge life under demanding feed and speed conditions. The insert seat size is 230. Installation and tip changes are performed by qualified machinists and toolroom technicians.

This drill is suited for production and job-shop environments where replaceable tip tooling reduces downtime compared to solid drill regrind cycles. The primary rated workpiece material is steel (ISO material code P), with secondary compatibility for stainless steel (ISO code K and M). Typical applications include through-hole and blind-hole drilling operations on CNC machining centers and drill presses where consistent hole diameter and positional accuracy are required. The 59/64 inch diameter fits common bore sizing requirements across structural, fabrication, and precision machining workflows.

Key Features

• Solid carbide replaceable tip with 2-facet insert geometry for clean entry and accurate self-centering
• 140-degree included angle optimized for steel and stainless steel drilling
• Nano-FIREX PVD multilayer coating reduces thermal load and extends tool life
• HT800 carbide grade rated for ISO P and K/M workpiece material classifications
• Replaceable tip design lowers per-hole tooling cost versus solid regrindable drills
• Insert seat size 230 for compatibility within the Series 4112 toolholder platform

Compatibility

Designed for use within the GUHRING Series 4112 replaceable tip drill platform with insert seat size 230. Verify shank and seat size match before ordering tip inserts or bodies separately.

Installation Notes

Tip installation and torque should follow the toolholder manufacturer's published procedure for Series 4112 bodies. Ensure the machine spindle is fully stopped and locked out before changing the replaceable tip. Inspect the insert seat for chips or debris before seating a new tip, as contamination can cause runout and premature tip failure. Coolant-through capability is not available on this configuration; verify coolant delivery method matches machine setup before use.
