Verified HSS Suffix Variant
Titan inventory directly verifies D167.025R-HSS as an HSS Jobber Drill, 2.5 mm, RH, distinct from the standard solid-carbide D167.025R item.


High-speed-steel right-hand 2.5 mm jobber drill stocked by Titan under the exact SKU D167.025R-HSS. The corresponding public D167.025R D167 core geometry is 2.5 mm diameter, 22 mm cutting edge, and 55 mm overall length.
Right Hand-hand HSS jobber drill with a verified 2.5 mm diameter and 55 mm overall length.
The D167 core geometry is used with D270 and D275 drill adapters in compatible drilling and boring systems.
The Royce Ayr D167.025R-HSS is Titan's HSS material variant of the D167.025R 2.5 mm right-hand drill.
Titan inventory directly identifies the exact suffix SKU as an HSS Jobber Drill, 2.5 mm, Right Hand. Public Royce D167.025R data establishes the core geometry at 2.5 mm diameter, 22 mm cutting edge, and 55 mm overall length. The D167 family is used with D270 and D275 drill adapters.
Because the exact HSS suffix variant is not exposed on the current public Royce product database, no HSS-specific performance or workpiece claims are added beyond the verified material and geometry. Confirm adapter bore, spindle direction, seating, runout, drill depth, feed rate, RPM, extraction, and workholding before production.
Technical Specifications
Titan inventory directly verifies D167.025R-HSS as an HSS Jobber Drill, 2.5 mm, RH, distinct from the standard solid-carbide D167.025R item.
The public D167.025R core listing establishes 2.5 mm diameter, 22 mm cutting edge, and 55 mm overall length for this SKU core.
D167.025R-HSS is configured for right-hand drilling positions and should be installed only in the corresponding machine station or spindle direction.
Confirm the exact SKU, rotation, drill-bank or adapter interface, toolholding condition, insertion depth, runout, drilling depth, workpiece support, and machine parameters before production. The exact HSS suffix is verified by Titan inventory; the 22 mm cutting edge and 55 mm overall length are inherited from the public D167.025R core geometry.
Royce Ayr D167.025R-HSS is the Titan-stocked HSS version of the D167.025R 2.5 mm right-hand drill, using the verified 22 mm cutting edge and 55 mm overall-length core geometry.
The page deliberately avoids assigning carbide or PCD material imagery or unsupported HSS performance claims because the public Royce database does not expose this exact HSS suffix variant.
