Guhring RT100 vs OSG ADO
RT100 and ADO are broad solid-carbide drill families rather than single identical tools. Both include coolant-fed high-performance and deep-hole variants, but their product families emphasize different geometries, coatings, material-specific versions and depth ranges.
Side-by-side comparison
| Category | Guhring RT100 | OSG ADO |
|---|---|---|
| Family structure | RT100 includes general-purpose, high-performance, deep-hole and material-specific drills across Guhring’s round-tool program. | ADO is OSG’s A Brand coolant-through drill platform with standard, stainless/titanium, micro and long-reach variants. |
| Deep-hole strategy | RT100 deep-hole variants use dedicated pilot-hole procedures and are offered in long depth ratios depending on series. | ADO variants are listed up to 40xD and 50xD, with R-gash geometry and through coolant supporting chip control. |
| Coolant and chip evacuation | Coolant-fed RT100 series and specialized flute designs are selected by material and depth. | Internal coolant, Mega Cooler geometry on selected variants and wavy/R-gash cutting edges target flow, lower thrust and chip evacuation. |
| Material specialization | Dedicated RT100 versions are listed for steels, cast iron, high-temperature and nickel alloys, among other materials. | General ADO targets steels; ADO-SUS is specifically positioned for stainless steel and titanium, with additional small-diameter variants. |
| Selection discipline | The exact RT100 suffix and series determine geometry, coating, coolant and depth capability. | ADO, ADO-SUS, ADO-MICRO, ADOX and long-depth ADO versions should be treated as distinct products. |
Best fit by application
Guhring RT100
- Use RT100 when a Guhring material-specific or depth-specific series directly matches the application.
- Guhring’s broad drill program can be advantageous where coating, reconditioning and custom-tool support are already standardized.
- Follow the pilot and entry procedure for long RT100 drills.
OSG ADO
- Use ADO where OSG’s A Brand geometry, EgiAs coating and coolant-hole design match the material and depth.
- ADO-SUS provides a clearer official path for stainless and titanium than a generic ADO selection.
- Long-depth ADO variants are relevant when no-peck or one-shot deep drilling is a primary process goal.
Selection notes
Select the exact RT100 or ADO variant from material and depth first. Neither family is universally broader in every application; the meaningful comparison is between two identified series at the same diameter, depth and coolant condition.
Variables to validate
- A family-name comparison is insufficient: exact series, diameter, depth ratio and material must be identified.
- Deep-hole drills may require pilot tools, entry procedures and minimum coolant pressure.
- Runout, coolant flow and chip evacuation usually dominate small-diameter tool life.
