Estimated shipping

Upgraded auto-lock—push up to unlock, turn to desired depth, release to auto-lock. No set screws, fast and easy.
Comes with a rigid plastic storage case with dedicated slots for each bit and accessory. Simply return each piece to its slot after use
Important note on receiving the order—upgraded vs. old version
We continuously improve the products. During transition, unavoidable a very small number of old units were mixed in. Old version works fine but lacks the auto-lock shown.
If you receive an old unit, just let us know—we'll process right away.
What material are the bits made of?
Alloy steel body with Tungsten Carbide Tipped (TCT) 2-flute cutting edges. Cuts cleaner and smoother than standard alloy bits
What sizes are included? How do I identify bit sizes?
5 sizes: 1/8"x3/8", 9/64"x3/8", 5/32"x3/8", 11/64"x1/2", and 3/16"x1/2". Each bit and its corresponding case slot are laser-engraved with the size—clear and easy to read at a glance
Any operation tips? Can this handle hardwoods?
Stop pressing immediately once the depth stop collar contacts the workpiece. Change bits on a stable surface to avoid losing the small screw. Optimized for wood, plywood, MDF, particle board
