Specialised tool for rigid tubing
The PrimoChill RFB Rigid Finishing Bit is a drill-mounted accessory built for custom watercooling loops. It reams, deburrs and trims hardline tubing in a single operation. The bit is sized for 12mm inner diameter and 16mm outer diameter rigid tube. Enthusiasts assembling PETG or PMMA loops will find it removes the need for hand reamers.
Sealed bearings and standard drill fit
Sealed bearings allow the bit to spin without scuffing the tube surface. The shank fits a standard drill chuck so no proprietary driver is required. At mid to low RPM it produces a smooth finish; at higher RPM it can trim the tube to final length. Rough cuts can therefore be fine-tuned after the initial saw cut.
Material limits and practice advice
The manufacturer advises against use with copper tubing because the bit dulls extremely quickly on that material. PETG and PMMA are the supported tube types. Users should practise on scrap pieces first to learn the material removal rate. No power or thermal figures apply to this hand-tool accessory.
