Guhring 9041120254000 Replaceable Tip Drill 1 Inch

Product Description

The GUHRING 9041120254000 is a replaceable tip drill from the Series 4112 product line, designed for precision hole-making in steel and stainless steel applications. The drill features a solid carbide insert tip manufactured from HT800 grade carbide and is finished with a Nano-FIREX coating applied via a PVD process. This coating provides enhanced wear resistance and thermal stability under demanding cutting conditions. The included angle measures 140 degrees with a 2-facet insert geometry, and the insert seat size is 250. The functional length of the tip is 15.80 millimeters. This tool is intended for use by machinists and tooling professionals in production and job-shop environments.

The 9041120254000 replaceable tip drill is suited for drilling operations in steel (ISO material code P) and stainless steel (ISO material code K and M). The 1-inch diameter tip fits into compatible Series 4112 drill bodies designed for that insert seat size. Typical applications include through-hole and blind-hole drilling in structural steel components, stainless fabrication, and general metalworking. This part is sold as a single replaceable tip insert and does not include the drill body shank.

Installation Notes

Installation of replaceable carbide tip drills should be performed by a qualified machinist or tooling technician. Ensure the drill body shank is fully secured in the tool holder and the machine spindle is powered down before seating or removing the carbide insert tip. Use the manufacturer-specified torque key or clamping tool for the Series 4112 insert seat to avoid damaging the carbide tip or the seating surfaces. Inspect the insert seat for chips or contamination before installing a new tip.
