Applications for Guhring
Guhring is ideal for production environments seeking to systematically reduce tooling costs and minimize downtime-related risks.
Its proprietary PVD coating technology forms a hard protective layer over the tool surface, while optimized edge geometries reduce wear and extend tool life. Coolant-through designs promote reliable chip evacuation and help maintain hole quality during continuous machining. As a result, tools require fewer replacements, reducing unplanned line stoppages and contributing to shorter takt times.
Note: Performance may vary depending on the product type and machining conditions, including spindle speed, feed rate, coolant, and machine rigidity.
Key Products
from Guhring
RT 100 XF Series

https://guhring.com/BrowseProducts/Products/RT-100-XF
Overview
The RT 100 XF Series is designed for high-feed machining, combining Guhring’s proprietary carbide substrate with a nano-FIREX coating to deliver exceptional wear resistance and toughness.
The substrate’s inherent “resharpening effect” helps suppress micro-chipping and reduces the risk of sudden breakage.
Available in 3×D, 5×D, 7×D, and 12×D lengths, the series uses a 140° point angle for 3–7×D tools and a 135° angle for 12×D—making it ideal for high-feed production drilling, especially in steel (ISO P).
This line supports better tool life management and helps reduce setup downtime during tool changes.
Compatible Materials
- Carbon and alloy steels (including structural and quenched/tempered grades)
- Stainless steels (austenitic, martensitic)
- Cast irons (gray, ductile)
- Non-ferrous metals (e.g., aluminum alloys)
- Nickel and titanium alloys
- Hardened steels
Lineup
- RT 100 XF 3×D (Series 6498)
- RT 100 XF 5×D (Series 5498)
- RT 100 XF 7×D（Series 5499）
- RT 100 XF 12×D（Series 6499）
GS 200 G Series

Overview
Featuring a 3-flute design for excellent centering, the GS 200 G Series offers high positional accuracy, excellent roundness, and superior surface finish quality.
Its 150° point angle makes it especially effective for fine finishing operations.
The combination of high centering stability and point angle geometry supports the creation of precise pilot holes, reducing defect rates in subsequent reaming or tapping processes.
By minimizing rework and secondary operations, the GS 200 G series helps improve overall part yield.

https://guhring.com/BrowseProducts/Products/Micro-Carbide-Drills
Overview
The ExclusiveLine VA/XL Series is engineered for deep-hole, micro-diameter drilling in high-precision fields like medical, aerospace, and automotive manufacturing.
The drills feature honed cutting edges optimized for small diameters, along with coolant-through designs capable of reaching up to 30×D.
These features suppress chip clogging and thermal damage during deep-hole machining.
The VA variant, designed for difficult materials like stainless steel and heat-resistant alloys, uses Guhring’s Perrox coating to prevent edge welding and ensure stable performance.
These features reduce critical risks such as tool breakage and burr formation when working with expensive materials, minimizing rework and scrap costs.
Compatible Materials
- Carbon and alloy steels (including structural and quenched/tempered grades)
- Stainless steels (austenitic, martensitic)
- Cast irons (gray, ductile)
- Non-ferrous metals (e.g., aluminum alloys)
- Nickel and titanium alloys
- Hardened steels

After-Sales Support
from Guhring
Guhring supports cost reduction across the full tool lifecycle.
Even after a solid carbide drill becomes worn, it can be restored to like-new condition at Guhring’s U.S.-based facilities.
The reconditioning process involves resharpening the tool and reapplying the manufacturer’s original PVD coating.
Since the same production process is used as for new tools, performance loss is minimal.
Authorized distributors handle the service process, offering seamless support from initial purchase through reconditioning—all within the United States.
