Gridfinity M3 & M4 Tap and Die holder for an Irwin Set with Hexagonal dies. It will also hold the proper size drill bit for each.

Will stack with my other Gridfinity storage for the Tap and Die holders and the M5, M6, and M7 taps and dies to be the height of one standard divider bin.

For M5, M6, and M7 Tap and Die or for the Irwin Tap and Die Holder in my profile.
