Carbon Fiber Filament Recommendations

[EMGMachinist]

Hey guys,I'm looking into designing and printing jaws (6" x ~3" x ~3") for a couple 6" vises that are gonna be used to clamp on a 5.75" dia x 30" lg piece of 1018 round stock in a horizontal mill. I need a filament that's gonna be strong and clamp the part securely, be deformation resistant, not prone to brittle failure, and won't be compromised by the use of machine coolant mechanically or dimensionally. We're going to be drilling a ~1.7" diameter hole 22" deep as well as some other operations to give you an idea of the forces at work. We bought a Bambulab X1C Combo kit with a 0.8mm hardened steel nozzle.

The filaments that look promising on their website are as follows:PET-CFCarbon Fiber Reinforced PETProduct Features:- Very Low Moisture Absorption- Exceptional Mechanical Properties- High Dimensional Stability- Exceptional Thermal Resistance- Comes with High Temperature Reusable Spool- Diameter: 1.75mm +/- 0.03mmCautions for Use- 0.2 mm Nozzle Not Compatible- Stainless Steel Nozzle Not Recommended- Dry out before use- AMS NOT CompatibleASA-CFProduct Features:- Superior Outdoor Durability- Optimized for Large Models- Sleek Matte Finish- Enhanced Stiffness for High Load-Bearing Applications- Diameter: 1.75mm +/- 0.03mmCautions for Use:- AMS Compatible- Enclosure Printers Required- 0.2 mm Nozzle Not Compatible- Hardened Steel Nozzle Mandatory- Dry Out Before Use

Just wondering which of these you'd recommend for this application, both are carbon fiber reinforced. Also, if you have any other recommendations by a different brand we'd consider those as well. Thanks!
