Walter Tools DC170 Supreme vs OSG A Brand AD-MICRO
Walter Tools DC170 Supreme and OSG A Brand AD-MICRO are documented holemaking systems with different product architecture and application priorities. DC170 Supreme is Walter's coolant-through solid-carbide drill family for high-performance drilling, with specified length variants from short through deep-hole ratios. OSG A Brand AD-MICRO is a small-diameter carbide-drill family released in 4D and 10D lists.
Side-by-side comparison
| Category | Walter Tools DC170 Supreme | OSG A Brand AD-MICRO |
|---|---|---|
| System architecture | Walter's catalog identifies DC170 Supreme as a 140-degree coolant-through solid-carbide drill family. | List 6004 is the 4D branch and List 6010 is the 10D branch. |
| Documented application focus | Production drilling in the ISO P and K material areas identified in Walter literature. | Small-diameter holes in steels and alloy steels. |
| Technical selection detail | Cited 16xD tools use DIN 6535 HA shanks and WJ30EJ cutting-tool material. | OSG specifies cutting-edge honing, point thinning, and Shoulder Edge Guard geometry. |
| Primary documented constraint | Depth ratio and diameter are embedded in the designation and cannot be inferred from the family name. | AD-MICRO and coolant-through ADO-MICRO are distinct families. |
| Manufacturer-guided selection | Store the complete Walter designation, diameter, depth ratio, grade, shank, coolant, holder, and reconditioning status. | Capture list, EDP, diameter, L/D, coating, coolant method, tolerance, material, and cutting-data source. |
Best fit by application
Walter Tools DC170 Supreme
- Production drilling in the ISO P and K material areas identified in Walter literature.
- Store the complete Walter designation, diameter, depth ratio, grade, shank, coolant, holder, and reconditioning status.
OSG A Brand AD-MICRO
- Small-diameter holes in steels and alloy steels.
- Capture list, EDP, diameter, L/D, coating, coolant method, tolerance, material, and cutting-data source.
Selection notes
Use DC170 Supreme when its documented application focus and technical configuration match the operation more closely; use A Brand AD-MICRO when its documented architecture and constraints provide the better fit.
Compare complete configured assemblies and current manufacturer data rather than treating either family name as one universal item.
Variables to validate
- DC170 Supreme: Depth ratio and diameter are embedded in the designation and cannot be inferred from the family name.
- A Brand AD-MICRO: AD-MICRO and coolant-through ADO-MICRO are distinct families.
- Normalize diameter or cutter size, reach, interface, work material, machine conditions, coolant, and acceptance criteria before comparing performance or cost.
