Guhring 9041150215000 Replaceable Drill Tip 21mm

Product Description

The GUHRING 9041150215000 is a replaceable carbide drill tip in the 4115 series, designed for use with modular drill bodies that accept insert seat size 215. It carries a 21.00 mm (0.8465 inches) cutting diameter and a 140-degree two-facet point ground to a relieved cone geometry. The tip is manufactured from solid carbide and finished with a PVD-applied nano-A coating, which reduces friction and extends tool life when cutting tough materials. Web thinning is incorporated into the geometry to reduce thrust forces at the point. This tip is installed and replaced by machinists and tool-room technicians in production and job-shop environments.

The 9041150215000 is suited for drilling stainless steel as its primary workpiece material, with secondary suitability for steel, cast iron, superalloys, and titanium. The regular helical flute profile and two-flute configuration support chip evacuation in these materials. The 140-degree point angle is appropriate for harder, abrasive alloys where a more blunt point improves edge stability and reduces chipping at entry. Typical applications include production-volume hole making in aerospace, general metalworking, and heavy fabrication where insert tooling is preferred for cost-effective tip replacement without removing the drill body from the spindle.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard-to-machine alloys
• nano-A PVD coating reduces friction and extends cutting life in stainless steel and titanium
• 140-degree two-facet point with relieved cone geometry for stable entry on tough materials
• Web-thinned design lowers axial thrust and reduces centerline heat buildup
• Two helical flutes with regular spiral promote consistent chip evacuation
• Insert seat size 215 for direct replacement in compatible 4115-series modular drill bodies

Compatibility

Designed for use with GUHRING 4115-series modular drill bodies requiring insert seat size 215. Specific compatible drill body part numbers were not provided in the product data; verify seat size and series compatibility against the drill body documentation before ordering.

Installation Notes

Replaceable drill tip inserts are seated and clamped using the screw or clamp method specified by the drill body manufacturer; ensure the mating seat is clean and free of chips before seating the insert. Use the torque specification published in the GUHRING 4115-series tool documentation for the clamping screw — do not estimate. Always de-energize and lock out the machine spindle before changing inserts. Inspection of the seat pocket for wear or damage is recommended each time the tip is replaced to maintain runout and dimensional accuracy.
