Precision tooling for hardline loops

The PrimoChill RFB Rigid Finishing Bit is a drill-bit accessory made for 10mm ID by 12mm OD rigid tubing. It reams, deburrs and trims PETG or PMMA tube ends in a single operation, removing the need for hand reamers and giving a clean, square finish that seals reliably in compression fittings.

Suited to custom-loop builders who want repeatable

Enthusiasts assembling hardline watercooling loops will appreciate the speed and consistency this bit adds to tube preparation. It is not intended for copper tubing because the material dulls the cutting edges rapidly, and it does not suit soft tubing or any inner-diameter size other than the stated 10mm.

Steady performance under sustained use

Sealed bearings keep the bit spinning without scuffing the tube surface even during longer trimming sessions. Running at mid to low RPM produces smooth deburred ends, while higher RPM lets you fine-tune tube length quickly; the supplier advises practising on scrap pieces first to gauge material removal rate.

Questions about this item

Does the 10 mm inner-diameter bit fit my existing standard drill?

Yes, the bit is designed to fit standard drills so you can use the drill you already own.

Will the finishing bit damage my 10 mm ID x 12 mm OD PETG or PMMA tubing if I keep using older copper tubing?

The bit is intended for PETG and PMMA only; copper tubing is not recommended because it dulls the cutting edges very quickly.

How can I confirm the bit is producing a clean, square end on the 12 mm outer-diameter tube after setup?

Run the drill at mid-to-low RPM and inspect the tube end — it should be smooth, free of burrs and perfectly square for a proper fitting seal.
