Guhring 9041150246100 Carbide Replaceable Tip Drill 31/32

Product Description

The GUHRING 9041150246100 is a carbide replaceable tip drill in the Series 4115 lineup, designed for precision hole-making in demanding materials. The replaceable tip accepts a solid carbide insert with a relieved cone geometry and a 140-degree included angle, making it well-suited for drilling into stainless steel and high-temperature alloys. The nano-A PVD coating reduces tool wear and supports higher cutting speeds. The functional insert seat size is 245, and the functional tip length is 15.80 mm. This tool is used by machinists and toolroom professionals in CNC drilling applications where consistent hole quality and insert changeability reduce downtime.

The 9041150246100 is built for use in primary workpiece material classification M (stainless steel) and is also rated for secondary workpiece material classifications H, P, and S, covering superalloys and titanium. It fits applications where through-coolant is not available, relying on the nano-A coating to manage heat at the cutting edge. Typical use cases include aerospace component drilling, stainless fabrication, and precision machining shops running CNC machining centers that require a modular, replaceable-tip drill system.

Key Features

• Solid carbide replaceable tip with relieved cone insert geometry for accurate self-centering
• 140-degree included point angle suited to drilling stainless steel and superalloys
• nano-A PVD coating applied via physical vapor deposition for extended tool life
• Insert seat size 245 for repeatable tip indexing without body replacement
• Compatible with stainless steel (M), superalloys, titanium (H, P, S) workpiece material groups
• No through-coolant required, reducing setup complexity on standard spindles

Compatibility

Designed for use as a Series 4115 replaceable tip drill insert with insert seat size 245. Suitable for drilling stainless steel, superalloys, and titanium workpiece materials per manufacturer grade K/P. Confirm body and seat size compatibility before ordering.

Installation Notes

Installation of replaceable tip drills should be performed by a qualified machinist following the drill body manufacturer torque and seating procedures. Power down and lock out the spindle before inserting or removing the carbide tip. Inspect the insert seat for chips or contamination before seating the new tip, as debris can cause tip runout and premature failure. Follow applicable shop safety procedures and machine tool manufacturer guidelines for tool changes.
