Guhring 9041150138900 Replaceable Tip Drill 35/64 in

Product Description

The GUHRING 9041150138900 is a carbide replaceable tip drill from the Series 4115 line, designed for precision hole-making in demanding materials. The drill features a solid carbide tip with a 140-degree included point angle and a nano-A PVD coating applied via physical vapor deposition. The replaceable tip design allows the body to be reused while only the cutting insert is swapped, reducing tooling cost per hole. With a relieved cone insert geometry and an insert seat size of 135, the tip locks securely into the body for consistent runout. A functional tip length of 8.50 mm supports accurate engagement at the point of cut. This tool is sized at 35/64 inch diameter and weighs 0.017 pounds.

This drill is intended for machining stainless steel as its primary workpiece material, with secondary application in superalloys and titanium. These material groups require a rigid, wear-resistant cutting geometry and an effective coating to manage heat and built-up edge. The nano-A finish addresses these demands in production and job-shop environments alike. The Series 4115 platform is suited to CNC machining centers and drilling cells where consistent depth and diameter tolerances are critical. Machinists and tooling engineers working in aerospace, medical device, and industrial manufacturing will encounter this drill in applications requiring reliable hole quality in difficult-to-machine alloys.

Key Features

• Solid carbide replaceable tip allows body reuse and lowers per-hole tooling cost
• 140-degree point angle optimized for stainless steel and superalloy entry without walking
• nano-A PVD coating resists wear and reduces friction in high-temperature cutting conditions
• Relieved cone insert geometry with size 135 seat ensures secure, repeatable tip seating
• Manufacturer grade K/P suitable for cast iron, steel, and non-ferrous applications
• 35/64 inch diameter with 8.50 mm functional length for controlled chip formation at entry

Compatibility

Designed as a Series 4115 replaceable tip insert compatible with GUHRING Series 4115 drill bodies accepting an insert seat size of 135. Confirm body seat size and shank interface before ordering.

Installation Notes

Replaceable tip drills are installed and serviced by machinists or toolroom personnel on CNC machining centers or drill presses. Before changing the tip, power down the spindle completely and follow lockout/tagout procedures. Use the appropriate torque wrench or insert key specified by the tool body manufacturer when seating the carbide tip — do not overtighten by hand or with unapproved tools. Verify runout after tip installation before returning the tool to production use.
