Finishing bit reams, deburrs and trims 10 mm ID by 14 mm OD rigid tubing using a standard drill
Option 10mm ID X 14mm OD
The PrimoChill RFB Rigid Finishing Bit is a dedicated drill-bit accessory for custom watercooling loops. It reams, deburrs and trims rigid tubing to a clean, professional finish. The tool is assembled and ready to use in any standard drill chuck, saving time compared with manual reamers.
Builders working with 10mm ID by 14mm OD PETG or acrylic tubing will appreciate the sealed bearings that prevent scuffing while spinning. The bit removes material quickly at higher speeds for length trimming, then smooths ends at lower RPM. Copper tubing is not recommended because it dulls the cutting edges almost immediately.
Compatibility is limited to rigid tubing with a 10mm inner diameter and a 14mm outer diameter. If your loop uses a different tube size, this bit will not fit and cannot produce the required finish.

The bit is sized for 10 mm inner and 14 mm outer diameter rigid tubing, matching those exact dimensions.
Run the drill at low speed; the bit should rotate smoothly without wobble or audible grinding.
The box contains one assembled Rigid Finishing Bit only; no extra bearings or case are included.
