Guhring 9041120142900 Replaceable Tip Drill 9/16 in

Product Description

The GUHRING 9041120142900 is a solid carbide replaceable tip drill insert from the Series 4112 line, designed for high-performance metal drilling applications. The tip is manufactured from DK460UF grade solid carbide with a K20/K40 material grade rating and features a Nano-FIREX coating applied via PVD process. This coating provides enhanced heat and wear resistance for demanding ferrous metal cutting. The insert measures 9.60 mm (0.378 inches) in height and features a 140-degree point angle with a 2-facet insert geometry. It is installed into compatible GUHRING Series 4112 replaceable tip drill bodies by tooling technicians and machinists in production and precision machining environments.

This replaceable tip insert is suited for drilling operations in steel and stainless steel workpieces, corresponding to ISO material groups P and K. The Series 4112 replaceable tip system allows worn tips to be swapped out without replacing the full drill body, reducing tooling cost in production runs. Typical applications include general-purpose hole-making in steel fabrication, machine shops, and production machining where consistent hole geometry and tool life are required. The 9/16 inch diameter tip targets mid-range bore sizes common in structural and mechanical component manufacturing.

Key Features

• DK460UF solid carbide grade with K20/K40 rating for high wear resistance in steel and stainless steel
• Nano-FIREX PVD coating provides thermal and abrasion resistance at the cutting edge
• 140-degree point angle with 2-facet geometry for accurate self-centering entry
• Replaceable tip design reduces tooling cost compared to full indexable or solid drill replacement
• 9/16 inch nominal diameter with 9.60 mm functional tip height
• No through-coolant required, simplifying setup on machines without high-pressure coolant systems

Compatibility

Designed for use with GUHRING Series 4112 replaceable tip drill bodies that accept a 140-degree insert seat at the 9/16 inch diameter size.

Installation Notes

Replaceable tip inserts of this type are installed and serviced by qualified tooling technicians or machinists. The drill body must be fully secured in the machine spindle and the machine must be powered down and locked out before removing or seating the tip insert. Follow the drill body manufacturer torque guidelines using the specified torque key for the insert seat — do not use improvised tools that may damage the seating surface. Inspect the insert seat for chips or contamination before installing a new tip to ensure proper seating and runout.
