ZEROPLAY 2-Step Plunge Bit - 1/4 in. Shank

Microjig ZEROPLAY Router Bit A2-Step Plunge Bit (1/4 in. Shank)

The Microjig ZEROPLAY Router Bit A2-Step Plunge Bit (1/4 in. Shank) is a specialty router bit from Microjig designed for making precise stepped holes and counterbores, mainly for jig-building systems like ZEROPLAY and MATCHFIT hardware.

It’s essentially a two-step plunge router bit that drills:

• a 1/4 in. (6.35 mm) through hole, and
• a 1/2 in. (12.7 mm) counterbore

This lets you quickly create consistent mounting holes without measuring or swapping bits mid-process.

This bit is mostly used in woodworking setups like:

• Table Saw Sleds
• Jigs And Fixtures
• Adjustable Fence Systems
• Hardware Mounting (Especially Microjig Systems)

The idea is speed + repeatability—every hole comes out the same, which is useful when building multiple identical jigs.

Why the “A2-step plunge” design matters

The stepped geometry:

• Reduces guesswork on screw depth
• Helps avoid over-tightening hardware
• Creates clean, repeatable mounting points
• Works in both a router table and drill press setups (depending on your workflow)
• Shank size note (important)

The 1/4-inch shank version fits trim routers and lighter-duty routers. It’s fine for jig work, but:

• It’s not meant for heavy material removal
• You should use shallow passes and good feed control
• It’s more about precision than aggressive cutting

This is a specialized jig-making router bit, not a general-purpose routing bit. If you’re building table saw sleds, fences, or Microjig-style systems, it’s very useful; otherwise, a standard straight or spiral bit is usually more versatile.
