.0157" Micro Carbide End Mill

In the CNC cue-making world, a .0157" (0.40mm) carbide end mill is an essential precision instrument for achieving the finest detail possible in custom cue construction. Its ultra-small diameter makes it ideal for executing micro-inlays, tight filigree patterns, and ultra-precise engraving operations where tolerances often reach within a few ten-thousandths of an inch.
 
Carbide tooling is the only reliable choice for such demanding applications because it maintains a razor-sharp edge even when subjected to the heat and vibration generated by cutting dense or resin-infused materials like Gaboon Ebony, Elforyn, or Juma. The stiffness and durability of carbide reduce tool deflection and chatter—key factors that allow this tool to cut cleanly rather than smear or burn at such a minute diameter.
 
For cue makers, the .0157" size is particularly effective when machining:
Micro inlays requiring surgical precision in fragile materials
Ultra-fine decorative ringwork with detailed geometric spacing
Microscopic engraving or logo work within cue butts and forearms
Tight corner detailing that demands perfect edge definition
 
This end mill allows cue makers to reach the highest levels of craftsmanship—producing crisp, sharp, and balanced details that distinguish a true custom-built cue. When combined with a stable spindle, accurate CAM programming, and proper chip evacuation, it becomes one of the most valuable cutting tools in the shop.
