Product Overview
The CGS Tool 507-0890 is a #43 solid carbide drill designed for precise, repeatable hole drilling on CNC equipment where hole size tolerance can't drift. At roughly 0.089” in diameter, this is a small-hole drill meant for pilot holes, tapping preparation, and fine-detail work where a standard jobber drill would flex or wander.
Machined from solid carbide rather than the more common HSS, it holds a sharper cutting edge for longer and resists the heat buildup that ruins small drills fast. The 2-flute drill point geometry clears chips efficiently even at this diameter, keeping the hole clean and reducing the risk of chip packing that leads to broken tools mid-run.
