Guhring 9041150222200 Replaceable Tip Drill 7/8 in

Product Description

The GUHRING 9041150222200 is a Series 4115 carbide replaceable tip drill designed for high-performance hole-making in demanding materials. The drill features a solid carbide tip with a 140-degree included angle and a nano-A PVD coating applied through a physical vapor deposition process. The replaceable tip design separates the cutting insert from the steel shank body, reducing tooling cost per hole while maintaining consistent geometry across tip changes. The 7/8-inch diameter and relieved cone insert geometry make it well suited for applications that require controlled cutting action and thermal resistance in tough workpiece materials. Licensed machinists and tooling technicians are the typical end users for this type of cutting tool.

This drill is engineered for primary use in stainless steel (ISO material code M) and is rated for secondary use in superalloys and titanium (ISO material codes H, P, and S). It carries a manufacturer grade designation of K/P, reflecting suitability across both carbide and steel workpiece families. The Series 4115 platform is a modular drilling system where tips are indexed or replaced without removing the shank from the spindle, reducing machine downtime. It is commonly used in CNC machining centers, horizontal mills, and automated turning centers in aerospace, medical, and general metalworking environments. Coolant-through capability is not included in this configuration.

Key Features

• Solid carbide tip construction for rigidity and wear resistance in hard materials
• 140-degree included point angle optimized for stainless steel and superalloy entry
• nano-A PVD coating reduces friction and extends tip life at elevated cutting temperatures
• Relieved cone insert seat geometry provides stable, repeatable tip seating at size 220 seat
• Replaceable tip design lowers per-hole cost compared to solid carbide drills
• Non-coolant-through configuration suitable for applications without internal coolant supply

Compatibility

Designed as a replaceable tip for the GUHRING Series 4115 modular drill body platform at insert seat size 220. Specific compatible shank body part numbers were not provided in the input data. Confirm seat size and shank series compatibility before ordering.

Installation Notes

Replaceable carbide drill tips should be seated and torqued according to the tool body manufacturer specifications using the designated key or driver — do not use improvised tools. Ensure the spindle is fully stopped and the machine is locked out before changing tips. Inspect the insert seat on the shank body for chips or debris before seating a new tip, as contamination will cause runout and premature tip failure. This tooling is installed and serviced by qualified machinists or CNC tooling technicians following shop safety and machine tool operating procedures.
