Sandvik Coromant CoroDrill 860 vs Guhring RT 100 Al

Sandvik Coromant CoroDrill 860 and Guhring RT 100 Al are documented holemaking systems with different product architecture and application priorities. CoroDrill 860 is a Sandvik Coromant solid-carbide drill platform split into application-specific GM, PM, SM, and NM variants. Guhring RT 100 Al is a solid-carbide drill platform for aluminum and other nonferrous applications.

Side-by-side comparison

Category	Sandvik Coromant CoroDrill 860	Guhring RT 100 Al
System architecture	Official product records use complete ISO/ANSI ordering codes and separate Sandvik material IDs.	Official Series 6062, 5768, and 6063 are listed as 3xD, 5xD, and 7xD RT 100 Al carbide drills with coolant through, an HA shank, and a 140-degree point.
Documented application focus	CoroDrill 860-GM for broad multi-material drilling where the exact GM item supports the work material.	Production drilling in aluminum where polished functional surfaces and internal coolant support chip evacuation and built-up-edge control.
Technical selection detail	Cited variants publish H8 or H9 achievable hole tolerance depending on the application-specific family and item.	Guhring describes optimized cutting-edge geometry, a relieved cone, a slightly concave main cutting edge, sharp cutting characteristics, and polished functional surfaces.
Primary documented constraint	The 860 family suffix is an application distinction, not optional naming; GM, PM, SM, and NM data should not be blended.	RT 100 Al is not one interchangeable drill; 3xD, 5xD, 7xD, micro-precision, and deep-hole series have distinct geometry and operating requirements.
Manufacturer-guided selection	Store the complete ordering code and material ID, including application suffix and grade, rather than shortening the record to CoroDrill 860.	Store the Guhring series, code, EDP number, diameter, L/D, point angle, shank, coolant configuration, and current cutting-data source as separate searchable fields.

Best fit by application

Sandvik Coromant CoroDrill 860

CoroDrill 860-GM for broad multi-material drilling where the exact GM item supports the work material.
Store the complete ordering code and material ID, including application suffix and grade, rather than shortening the record to CoroDrill 860.

Guhring RT 100 Al

Production drilling in aluminum where polished functional surfaces and internal coolant support chip evacuation and built-up-edge control.
Store the Guhring series, code, EDP number, diameter, L/D, point angle, shank, coolant configuration, and current cutting-data source as separate searchable fields.

Selection notes

Use CoroDrill 860 when its documented application focus and technical configuration match the operation more closely; use RT 100 Al 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

CoroDrill 860: The 860 family suffix is an application distinction, not optional naming; GM, PM, SM, and NM data should not be blended.
RT 100 Al: RT 100 Al is not one interchangeable drill; 3xD, 5xD, 7xD, micro-precision, and deep-hole series have distinct geometry and operating requirements.
Normalize diameter or cutter size, reach, interface, work material, machine conditions, coolant, and acceptance criteria before comparing performance or cost.
