Guhring 9041150190500 Replaceable Tip Drill 3/4 in

Product Description

The GUHRING 9041150190500 is a carbide replaceable tip drill from the Series 4115 line, designed for high-performance drilling in demanding metalworking applications. 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 uses a relieved cone insert geometry seated in an insert seat size 190 body, allowing the tip to be swapped without replacing the full shank. This drill is suited for machining operations where consistent hole quality and tool life are critical priorities. Machinists, CNC operators, and toolroom technicians are the primary users of this tooling.

The 9041150190500 is engineered primarily for cutting stainless steel, with secondary suitability for superalloys and titanium. The 3/4-inch diameter and 12.60 mm functional length make it appropriate for through-hole and blind-hole applications in tight-tolerance machining environments, including aerospace, medical device manufacturing, and industrial fabrication. This drill does not include coolant-through capability, so external coolant or flood cooling should be planned during setup. The nano-A finish reduces built-up edge and improves chip evacuation in tough, work-hardening materials.

Key Features

• Solid carbide replaceable tip construction with relieved cone insert geometry
• 140-degree point angle optimized for flat-bottomed entry and reduced thrust in tough alloys
• nano-A PVD coating for improved wear resistance and reduced friction in stainless and superalloy cutting
• Insert seat size 190 body accepts direct tip replacement without full tool discard
• Manufacturer grade K/P with secondary material codes H, P, and S for broad alloy compatibility
• Weighs 0.026 pounds, keeping toolholder load minimal in high-speed spindle setups

Compatibility

Designed as a replaceable tip insert for GUHRING Series 4115 drill bodies with insert seat size 190. Compatible drill bodies must match the relieved cone insert geometry and 190-series seat specification. Confirm shank and body compatibility before ordering.

Installation Notes

Installation of replaceable tip drills should be performed by qualified machinists or CNC toolroom personnel following the drill body manufacturer's torque and seating procedures. Ensure the spindle is fully stopped and the machine is locked out before changing the tip insert. Inspect the insert seat for chips or debris before seating the new tip, as contamination can affect runout and hole quality. Do not exceed the rated cutting parameters for the workpiece material grade.
