Title: 6 mm Micro-Boring – Three Shop Floor Problems, One Diamond Edge

Small bores aren't hard to machine. What's hard is machining them consistently, at volume, with zero drift.
The Palton 6 mm PCD micro-boring bar was built to solve the three most persistent challenges in precision finishing:

① Chatter & Deflection → Carbide Dampens It
Solid carbide shank offers 3x the rigidity of steel. No "spring-back" during deep, small-diameter boring. Diameter stability holds tight.

② Built-Up Edge → PCD Rejects It
PCD has no chemical affinity for aluminum. Heat flows into the chip, not the tool. No BUE formation—even on high-silicon A390, even in dry cutting.

③ Sub-Par Finish → Mirror Finish in One Pass
Copper, aluminum, magnesium, composites—clean exits, no burrs, and surface roughness reduced by 60% or more. Eliminates one polishing or honing operation in most cases.
