Tap and Drill Bit Cases

For Drill Bits


Steel	Plastic

Store and organize drill bits so they stay in good working condition and don't go missing. These cases have individually marked holes for each size in your set.

Steel—Steel cases have stands that fold in and out. Stand them up when you need them, then fold them back into the slim case for storage inside a workbench drawer.

Plastic—Plastic cases have screw-on lids to block out moisture. Compared to steel cases, they're lighter, and they resist rust and dents. Clip them onto your belt to take with you on the job.
