Guhring 9041120155000 Replaceable Tip Drill 15.5mm

Product Description

The GUHRING 9041120155000 is a replaceable-tip drill insert designed for use in Series 4112 modular drill bodies. The insert features a solid carbide tip with a Nano-FIREX PVD coating, a 140-degree point angle, and a 2-facet insert geometry. At 15.5mm in diameter and 9.80mm in functional length, it is engineered for precision drilling in demanding production environments. The Nano-FIREX finish provides enhanced wear resistance and thermal stability, extending tool life in high-cycle applications. This insert is sold individually and is intended for replacement of worn or damaged tips rather than full drill body replacement.

This insert is suited for drilling steel and stainless steel in industrial machining environments. Typical applications include CNC drilling operations in job shops, production facilities, and manufacturing plants where modular tooling systems are preferred for reduced tooling cost and faster changeover. The Series 4112 platform is a common choice for through-hole and blind-hole drilling in structural and alloy steel components. Installation and changeover are performed by machinists or CNC tooling technicians following standard insert-seat torque procedures per the toolholder manufacturer guidelines.

Key Features

• Solid carbide tip with manufacturer grade DK460UF and material grade K20/K40 for hardness and toughness balance
• Nano-FIREX PVD coating for improved wear resistance and reduced built-up edge in steel applications
• 140-degree point angle with 2-facet geometry for self-centering entry and reduced thrust force
• 15.5mm diameter insert seat size 155, compatible with Series 4112 drill bodies
• 9.80mm functional length for controlled cutting depth at the tip interface
• Rated for primary use in steel (ISO P) and secondary use in stainless steel (ISO K/M)

Compatibility

Designed as a replacement tip insert for GUHRING Series 4112 modular replaceable-tip drill bodies with insert seat size 155. Confirm drill body insert seat size before ordering.

Installation Notes

Installation is performed by machinists using the appropriate Guhring torx or insert key for Series 4112 toolholders. Power down and lock out the machine spindle before any insert change. Seat the insert fully into the pocket and torque to the specification listed in the drill body documentation - do not substitute generic torque values. Inspect the insert seat for chips or debris before each installation to ensure accurate seating and runout performance.
